Mercedes-Benz C 200 CDI 115hp W203

2000 — 2006 C-Class

With the C-Class, an package of technical innovations was in, on an unprecedented level for this segment. Never before has so attention been paid in vehicle class to the aspects of and comfort as in the development of the Mercedes-Benz which with this technology guarantees a maximum of dynamism and driving pleasure.

at first glance the attractive with its modern interpretation of the headlamp face, expresses two of the key of the C-Class, namely dynamism and The sedan is a youthful, progressive car is characterized by newly developed technology, powerful engines, the technical innovations and, in sporty agility. These features are combined in the C-Class traditional Mercedes qualities as the maximum possible safety, top exemplary comfort and superb

The standard equipment of the sedan pioneering technical innovations were previously only in the flagship models bearing the 3-pointed star: windowbags, airbags for driver and front Headlamp Assist, the multifunction wheel and fiber optics are a few examples of a whole host of new that make the C-Class a trailblazer in its market segment. more than 20 technical from the Mercedes flagship were included as standard in the

In addition, maximum safety is by standard-fitted systems such as the Stability Program (ESP), Assist, automatic child seat recognition, seat tensioners and belt force for the front seats and rear seats, head restraints for all and side impact airbags in the doors. The SPEEDTRONIC electronic limiter and the 6-speed manual are also fitted as standard.

to the outgoing model, Mercedes-Benz has the value of the standard equipment of the by about 3700 DM.

Exterior

formation — this was the brief. They were with giving the Mercedes-Benz a dynamic character which instills affection and from the first glance leaves no about its pedigree. In short, the sedan had to visually reflect -Benz’s new, progressive image. But, in addition to dynamics and youthful attractiveness, the also specified embodying the elegance of a Mercedes sedan. The of the C-Class was a study in integration. It different worlds and spontaneously the attention of people with different aspirations and interests. design and equipment lines the realization of individual wishes in of form, colors and materials.

and elegance, that was the aim. two dozen designers set to work, their visions and ideas to discussed many hundreds of and transferred the best of them to the world of the computer so that could experience them in dimensions on special-surfaced screens. The finally fell on a draft which unites all the objectives in fashion: dynamism, emotional elegance, solidity and continuity in other words, the typical language of form.

Twin merge into harmonious

The headlamps are again character-shaping While the famous twin-headlamp of the E-Class in 1995 was the visible of a new departure for the Mercedes-Benz brand, the re-interprets this symbolism, marking the launch of the next in Mercedes-Benz’s product offensive. the sedan’s four “eyes” are identifiable. the design of the C-Class has the oval headlamps merge harmonious units in line the basic brief of integration. The and fenders pick up this finish and continue it backwards in curves, forming elegant sculptures. Associations with the anatomy are inescapable, as the shape of the is reminiscent of the muscles of trained

Seen through the eyes of the these athletic forms the width of the car’s body, a powerful appearance particularly viewed from the front. effect is reinforced by the bumper is perfectly integrated in the bodywork the discreetly molded spoiler in the lower section and the front fog especially as all the components use the same — in body color and therefore present a unified in color terms too.

The of dynamism and elegance is also in the radiator grille and headlamps. The have skillfully worked different rake angles to draw attention to the C-Class’s two while the slightly raked are reminiscent of a sports car, the and webs of the radiator grille are more upright. The effect of stretching the hood in this way is to the car power and elegance.

Seen the side: pronounced wedge-shaped and powerful shoulders

Seen the side too, the dynamic of the C-Class is the dominant first This is ensured primarily by the wedge-shaped body which is defined by the curve along the The conscious emphasis on what is known as the waistline actually to mind the broad shoulders of a athlete, topped by the side roof pillars and roof. line runs continuously the front to the rear end, form to the power of the body particularly at the rear where the C-pillars meet it and jointly the form of the rear end.

But the raked windshield, the coupé-like and the flat backlight are unmistakable of a spirited use of forms with emphases from the world of sedans.

Like the headlamps, the lamps are now also regarded as stylistic elements of Mercedes with a sporty yet elegant The tail lamp covers in a wedge shape into the of the body, underlining the car’s lines. This overlapping design was first used on a car in the SLK roadster and then also the eye in the S-Class and the top-of-the-range CL coupé not just because of its striking but also as an integrating style for formally linking the side and sections.

Further similarities other Mercedes models are in the V-shaped cut-out in the tail of the which is also formed by the lamps. They ensure the integration of the entire rear end the visual links between the trunk lid and bumper. At the same the trapezoidal tail lamp and the large-format bumper emphasize the of the sedan, which therefore makes a particularly powerful from the rear. The bumper almost seamlessly into the and also forms a unified in color terms with the metal skirt.

A successful of dynamism and elegance

Updated of twin-headlamp face

Distinctive as a symbol of power

Body

The C-Class has long meant to Mercedes-Benz than just a sedan. The C-Class has developed a complete model family and provides other Mercedes with a solid technical The same will hold for the new model range.

In the core of body technology, the new C-Class trailblazing trends, as the results of tests on the test stand

The static torsional resistance of the structure (without windows) a new top result for this vehicle with 3.57 millimeters per This value surpasses the result of the outgoing C-Class by more than 26%.

The of different body parts as the center tunnel and side measured in terms of static is up to 50% higher than for the outgoing

The dynamic resonant frequencies for and bending of the new sedan are up to 12% better for the outgoing model.

The occupants of the new will feel the benefits of advances especially in the improved and vibration comfort and in enhanced protection.

Recycled materials and materials are part of the materials

In addition to aluminum and plastic, the composition of the C-Class is still by steel, as the proven material, but the of high-strength panels, which minimal panel thickness and with a maximum of strength, has more than doubled to the outgoing model. One feature in field of material technology is the phase” steel. Its high conferred by its two-phase microstructure high crash stresses and plays an essential part in the solidity of the front end and occupant

Recycled materials and natural are all part of the materials concept for the Mercedes-Benz have approved a of 38 plastic components with an weight of some 30 kilograms for the use of materials; this represents 13 percent of all plastics used. A 33 components in the sedan are made of materials such as wool, coconut, wood and other fibers. They weigh under 23 kilograms in total 27 percent more than in the model. Thanks to its environmentally materials mix, the Mercedes-Benz achieves a recycling potential of 85 percent by weight and therefore meets the provisions of Germany’s Car Decree which will not into force until

New firewall concept for even occupant safety

The new firewall is out of six different individual components of panel thickness. In this Mercedes engineers adapt the to the relevant load and obtain an compromise between lightweight and crash safety. The special curve of this innovative also gives it its name: the firewall”. As in the Mercedes-Benz S-Class, large part plays an role in the safety concept of the since it is not only able to extreme loads but can also crash impact forces over a wide area, preventing dangerous intrusions the occupant cell. In the outgoing this function was performed by the side members, which are now no required.

The Mercedes-Benz S-Class and CL Coupe also provided the for the development of other front end For example, the front module of an independent unit that the same advantages in each version. Bolts reliably the module to the remainder of the body. the individual sheet metal inside the module are bolted so that accident damage can be faster and at lower cost. is no longer required when individual components or the entire module. The key components of the front are two steel crash boxes absorb the impact energy of frontal collisions, thereby damage to the load-bearing structure The advantage of this system is the crash boxes and load-bearing are fastened together by bolts and can be without problem after an This cost-cutting crash is operative for crash speeds of up to 15 against a rigid obstacle.

crossmembers and robust doors for impact protection

In a side crash, three crossmembers in the area and a solid square section under the instrument enter into action to the passenger compartment. The single-piece panel of the side wall individually welded inner that confer even strength to the roof pillars, frame and outer side The doors too consist of an outer and an shell and of several inner reinforcements. In addition, a flexible member is fitted in the lower of each door to reduce the in a side impact crash.

foam elements in cavities

and safety were not the only in the design of the occupant cell: the of noise comfort was also on the from the start. In this body engineers have a major contribution by filling cavities of the bodyshell with or fiber materials. These are first mounted on special plates and firmly fastened to the then, in the drying zones of the shop, these soundproofing expand automatically and completely the cavities. Overall, 42 of these or fiber elements are concealed the metal skin of the C-Class. of the two side walls alone 11 foam absorbers.

Steel panels with corrosion protection ensure

In many European countries, gives its car buyers a cost-free warranty for mobility and sustained “mobilo-life” is valid for 30 years and includes comprehensive warranty in the event of rust perforation of the and underbody, provided that the car has regularly serviced and maintained by an Mercedes workshop.

This promise is based on comprehensive protection. For the C-Class, the engineers in Sin have again enhanced the protection measures. Three aims were pursued: use of materials, avoidance of waste and the of environmentally critical materials. The is a bodyshell that has 85% of its total protected against corrosion by coating. By comparison, in the outgoing the share of zinc-coated panels was 65%.

Instead of an all-round galvanized body, Mercedes-Benz on steel with dual protection: electrolytically zinc-plated are additionally coated with an paint that also rust-inhibiting zinc pigments. this paint is only two to micrometers thin, it withstands the generated by pressing and spot-welding the thereby ensuring lasting Almost half of the galvanized parts of the C-Class are made of innovative steel sheeting. For the end, side members, and the inner shells of the doors, and trunk lid, Mercedes-Benz sheeting with organic on both sides. This therefore also replaces cavity sealing in many

Mercedes engineers have been able to dispense the conventional PVC underseal in the C-Class, nevertheless still guaranteeing corrosion protection in this The solution to the problem is an underbody made of glass-fiber reinforced which also offers advantages.

Exemplary Cd value of means best-in-class aerodynamics

driving on the motorway, more half the fuel consumption of a car can be attributed to wind drag. fact alone explains one of the why Mercedes engineers have themselves so intensively to the subject of for many years. In the C-Class, commitment is crowned with success: with a Cd value of 0.26, the C 180 is the most aerodynamic sedan of its market segment in the

Compared to the outgoing model, the engineers at Mercedes have able to reduce drag by a 13%, thereby bettering the exemplary Cd value of the E-Class and (0.27), previously the best in this aspect of body The product of frontal area (A) and which crucially affects consumption is about 13 per cent than the comparable figure for the C-Class,

The exemplary Cd value of is essentially due to the following body

Front air dam and rear skirt: function is to control the slipstream, it to the sides at the front, so that it back smoothly and finally from the body at the rear little turbulence.

Spoiler lip on the lid: this elegant improves the escape of the slipstream, lift and preventing the formation of behind the body.

Wheel at the front and rear wheels: small plastic elements the back pressure of the air in front of the thereby reducing the Cd value. At the time they reduce

Underbody encapsulation: The large, plastic panels that back to just in front of the axle allow the slipstream to back underneath the body turbulence.

Engine compartment Complete encapsulation of the engine not only improves acoustic but also guides the slipstream downwards and prevents the air swirling in the area.

Superlative aerodynamics excellent directional stability

A coefficient of drag is not the only that counts for Mercedes-Benz engineers. They are only if their work also the interests of road safety. The here is lift: the sedan is by exemplary stability, as is proved by the for front and rear body which are up to 57% lower than the values for the predecessor model. is due to the encapsulation concept for the underbody, the spoilers for the front and rear the elegant spoiler lip on the trunk lid and the developed flare elements in of the front wheel arches.

New functions for greater safety and

In the C-Class, the driver no longer has to about switching the headlights on and because this task has taken over by electronics the aid of a light sensor mounted on the This “Headlamp Assist” as it is called, which until was only available for luxury and top sports cars, is now included as in the Mercedes-Benz C-Class. This function is programmed by the multifunction wheel on the central display in the cluster and is activated by the light on the instrument panel (“Auto” In addition, electronic data bus on board the sedan permits a range of additional lighting and switching facilities that both safety and comfort:

light: If a data line or control unit is defective, a circuit prevents failure of the vehicle lighting system.

lighting: If bulbs important to safety go out, the electronic automatically switches on other that can provisionally replace the light.

Daytime driving The driver can program the light of the C-Class to switch on the low beam parking lights, rear and license plate light after switching on the engine.

switch-off delay: Optionally, the remain switched on even the occupants have left the car in to help them find way around in the dark.

Four functions in a single headlight

The headlights are not only important features of the C-Class but also set an by their modern technology. The rounded plastic lenses a two-chamber reflector that four lighting functions: the zone is used for low beam above it, the turn signal whilst the inner reflector is reserved for the high beam and sidelight. In other words, in the of increased light output, the low and high beam are housed The fog lamps are housed in the front trim.

Also new are the exterior housings with integral signal repeater lights. In high position they particular attention and therefore clear safety benefits.

light and high-pressure headlight available as an option

Instead of the H7 bulbs for the low beam headlights, headlights with gas discharge are optionally available to provide an similar to daylight. These are characterized by twice the light longer service life and a power consumption of only 35 Dazzling of oncoming traffic is by a dynamic headlight range system. With the aid of inclination on the front and rear axles, system detects brief of the car body when starting rest, braking or accelerating. the reflectors always follow the body position and adapt the of the beam accordingly. The newly headlight cleaning system water-jet technology. A telescopic unit is mounted under headlight, behind the bumper This telescopic unit is at the touch of a button and in response to the pressure to reveal two cleaning that spray a precisely quantity of water against the

The rear lamp units of the are recessed deep into the sides and contain the brake turn signal light, light and reversing light, with the rear fog lamp on the side. The brake lights in the lamp units are coupled to the raised brake light in the lid. This third light consists of 20 LEDs light up about 50 milliseconds than conventional bulbs in to the brake pedal. The LEDs make a major contribution to the of rear end accidents.

Interior

You it immediately on the first encounter: the C-Class has matured even and is even more comfortable before. The design of the interior, its equipment and classy appeal the premium character of the sedan more strongly than in the model. Anyone who sits in one of the two developed front seats feel immediately at ease and have no trouble finding the desired position. All the most driving controls the gear ventilation outlets, pushbuttons and are arranged within easy of the driver, and their functions are recognizable. Everything is literally to and in view.

One of the main aims has “rational automation”, so that the can concentrate on the essentials, namely the situation and the driving experience. As a certain functions on board the are automatically controlled and monitored. functions focus on the routine of drivers, thereby relieving the exactly where most Examples from a wide of settings:

Once programmed and set on the switch, the exterior lights are switched on in dark conditions.

All windows and the sunroof can be closed a single touch of a button on a tunnel or underground parking

Once programmed, on inserting the key, the seats, steering and rear view mirror to the position desired by the front The key also stores the settings of the climate control.

Once on removing the ignition key, the seat is always moved and the steering column automatically for a more comfortable exit.

activated, the optionally available automatic climate control to air recirculation mode upon increased pollutant levels in the air.

A touch of a button on the wheel is sufficient to instruct the car CD or cassette player and car phone to the driver’s spoken commands by of the LINGUATRONIC voice control

Individual settings can be stored the steering wheel

Many of settings are entered with the aid of the multifunction steering wheel, is coupled to the central display in the cluster and to the car radio and car phone. The simply has to touch the lower button in the steering wheel in order to display the main menu, where more 50 individual functions can be programmed five different submenus digital speed display to door locking once on the from automatic mirror for parking to the easy exit/entrance

In addition to these individual options, the central display provides a whole range of messages and data: daily and distance traveled, engine oil next service due, temperature, name of radio when listening to the radio, number when listening to or CDs, recommended directions of the system, fault messages or distance to empty.

The instrument has been redesigned. Instead of the round instruments, three displays indicate the engine (left), speed (middle) and level (right). The telltale and lights are located under the rev inside the middle speedometer and under the fuel gauge. lights only come on the ignition is switched on or if there is a otherwise the instrument panel dark at these points.

The is three times the size of the model

The top section of the dashboard the instrument cluster cover and the and middle ventilation outlets, have a modern, cylindrical that integrates perfectly in the front edge. The lower of the dashboard includes the knee on the driver’s and front passenger’s which is made of a special of polymers with a soft film, and the center console and glovebox that is part of a stowage space concept. a volume of 8.2 liters and measuring 400 wide by 162 millimeters deep, the is almost three times than its equivalent in the outgoing (3.0 liters). Consequently, a CD can now optionally be installed in the upper of the glovebox. A compartment for sunglasses or spectacles is also built the glovebox. The pockets in the interior of the driver’s and front passenger’s provide sufficient space to an umbrella, road maps, an ice and spectacles cases. The capacity of of these door pockets is 3 liters and is therefore double of the outgoing model. The cover of the stowage box between the front also serves as a padded which in the Elegance and Avantgarde as well as in conjunction with or THERMOTRONIC is adjustable in two tilt

Comfortable, improved spaciousness for all

The C-Class has the typical comfortable of a Mercedes. The occupants of the front have a shoulder room of millimeters and an elbow width of millimeters, representing increases of 11 and 8 respectively on the equivalent dimensions of the model. The comfort of the rear has been improved by extending the by 4 millimeters and the elbow room by 12 The rear headroom in models a sliding sunroof is 948 millimeters 10 more than previously.

by the VDA measuring method, the trunk has a of 455 liters including a stowage of 45 liters in the handy recess Mercedes -Benz provides of the traditional spare wheel. recess holds not only the toolkit but also the TIREFIT repair kit and the electric air pump get the driver back on the road in the of a flat tire without to fit a spare wheel

The driver and passenger of the C-Class can make thoroughly comfortable on the newly seats that combine design with significant especially in the fields of ergonomics and Whereas the occupants previously had to the seat height and backrest angle manually, each of functions has now been taken by two electric motors. All the occupant has to do is to a two-part switch on the outer trim, and the seat cushions and immediately move to the desired

A microchip in the ignition key stores seat adjustments

Even operating convenience is provided by the power adjuster package for all of the driver’s and front passenger’s available as an option from In this case, not only the height and backrest angle but the longitudinal adjustment, seat angle, head restraint, column and exterior rear mirrors are adjusted by electric A microchip stores the individual data of the driver’s seat and it to the electronic ignition key. as soon as the driver inserts the key in the starter switch, the seat, restraint, steering wheel and rear view mirror move to the desired position.

to the outgoing model of the C-Class, the at the Mercedes plant in Sindelfingen, have improved the lateral and support of the seat cushions. The basis for the front seats is by two suspended aluminum shells can rotate at the front for the tilt facility and that rest on two coil springs at the rear. the seat shells rock on the frame and can perform additional and damping functions to supplement the of the foam cushions lodged in the frames. A comfortable seat is ensured by ventilation holes in the cushion, an 8-millimeter thick of rubberized hair and the fabric cover, which, due to its high content, has highly active properties.

Split-folding rear bench available as an option

For who wish to vary the trunk of their sedan, Mercedes-Benz has an asymmetrically split rear bench that can be folded in a few simple steps at a ratio of First, the seat cushions are forwards individually or together a vertical position behind the seats. Then the backrests are forwards to produce an almost flat load floor.

controlled heating system for comfort

“Heatmatic” is the name by Mercedes-Benz engineers to the automatic and ventilation system on board its cars. As the name indicates, is a little more than an ordinary, conventionally engineered Heatmatic consists of an electronically system that measures the temperature by means of sensors and it constant at the level desired by the and front passenger. This technology has long been in use at Mercedes-Benz and has now been further and improved by Mercedes engineers for the The control panel for the heating and system is characterized by a design provides a clearly organized of all relevant functions, namely the fan adjustment (previously 4-speed), air separate temperature controls for the and front passenger, air recirculation defrost mode and heated window.

Furthermore, the number and of the various outlets in the dashboard and footwell have been to provide comfortable in other draft-free ventilation. This aspect of draft prevention was behind the development of an innovative ventilation system that has its at Mercedes-Benz. An outlet located in the of the dashboard and directed at the windshield cold air over a wide and therefore without causing a

Electric heater booster for CDI

In addition to the standard-fitted Heatmatic the diesel models of the C-Class are with an additional electrical system to ensure pleasant in the interior. This heater is necessary because although the CDI of the C-Class have the advantage of very little fuel, due to high thermal efficiency only transfer little to the coolant when running at As a result, the heating effect is than in a car with a conventional The additional heating requirement of the CDI is also supplied by a water-cooled (190 Amp) that at up to 18000 rpm when the car is on the move and its waste heat to the coolant.

sensor and variable compressor for air conditioning

When it comes to air Mercedes customers have a with the C-Class. Two systems are the THERMATIC automatic climate with automatic fan control and air (standard in the C270 CDI, and C320 models) and the THERMOTRONIC automatic climate control an activated charcoal filter, a sun and sensor and many other functions. Compared to the outgoing the electronic air conditioning control has further improved: for example, two (previously one) are now used to the interior temperature and to supply the with even more data, so that it can respond more rapidly to temperature

The newly developed automatic control of the C-Class operates on the basic principle as many air conditioning systems namely the principle. In other words, at cold outside temperatures, the is in permanent operation and always cools the incoming air, drying it so that the windows mist-free. The air is then reheated to the temperature. The new feature of this circuit is a 3-stage control that activates the reheat as a function of relative humidity. feature has been made by a newly developed dew point which supplies the air conditioning with the data required for control of the 3-stage reheat and ensures that the incoming air is and then reheated as a function of its moisture level. As a result, the air operates much more than conventional systems.

The has also been made by the use of a new refrigerant compressor with variable electronic control as a of the cooling power actually Whereas until now the air conditioning was engaged or disengaged with the aid of an clutch, it is now directly connected to the by belt drive, so that it is in operation. The infinitely variable function is provided by a solenoid

The system stores the individual settings and transfers the data to the ignition key. This function ensures that the climate control will with the desired program on the journey.

THERMOTRONIC for luxury climate control like in the

The newly developed luxury climate control lives up to its it brings S-Class comfort to the Examples of this luxury include:

Automatic control of and air distribution individually for the driver’s and passenger’s sides;

Additional signals for sunlight and pollutant in the outside air;

Standard-fitted charcoal filter;

Clearly display for temperature and fan speed;

of additional individual setting in the electronic ignition key;

outlets at the rear.

The Mercedes-Benz is the only car in its market segment to automatic climate control sensors for sunlight and pollutant as well as an activated charcoal

Electonics

All the latest-generation telematics are being premiered in the Mercedes-Benz They not only optimize traffic-jam warnings and use all the latest data to guide drivers to their destination, but also for the time provide a direct to the team of advisers at the Mercedes-Benz Assistance Center who can give in the event of technical queries or breakdown assistance.

With routing, the navigation system the connected car phone to contact Telematics, a joint venture in Bonn between DaimlerChrysler and phone company T-Mobil. Telematics analyzes the information Gesellschaft für Verkehrsdaten, a data provider that the traffic situation on German by means of about 3800 or ultrasonic sensors. Using the Message Service (SMS ) of the phone network, Tegaron congestion warnings to the dynamic system of the C-Class, which the latest traffic information account for the individual routing and recommends an alternative route in the of a traffic jam. As soon as the calculates an alternative route, a in the loudspeaker announces: “This has been computed on the basis of news,” and the message “Congestion appears on the navigation system

Radio Data System digital traffic data to the car

A possible method of receiving traffic data and using it for routing is provided by the Radio System (RDS) over the Message Channel (TMC). On channel, radio broadcasters inaudible signals that the system decodes and evaluates. signals contain traffic jam that are put together with the aid of loops in the road surface of or on the basis of information provided by the The information contained in these corresponds to the traffic news of the (audible) radio stations and is of charge. RDS-TMC is already in all over Europe. Dynamic with this technology is operational in Germany, and preparations are under way to introduce the system in European countries.


The system for dynamic routing is the APS navigation (Auto Pilot System) by Mercedes-Benz. This system drivers automatically to their with the aid of GPS (Global Positioning satellites, wheel sensors and road maps.

Car radio navigation system and dynamic

A choice of two combination units navigation systems with the for the modern “dynamic routing” service is available for the C-Class. The 30 APS combines an FM/MW/SW/LW tuner, CD and navigation system inside a housing that is the size of a car radio. The unit also a built-in 4-channel amplifier watts), LCD display, GPS tuner and diversity system, which the signals from four antennas. Radio reception is on the two-tuner principle: while one tunes into the radio selected by the driver, a second in the background constantly monitors the quality of all receivable transmitters. As a the radio can immediately switch to another frequency of the desired

In order to reach the desired under the guidance of the APS navigation the driver must insert the containing the digital map in the combination when specifying the destination. The car then stores the necessary of the CD-ROM and starts calculating the At this point, the CD player can be used to play music

COMAND integrates all communications features

The other system the navigation system and dynamic is the Cockpit Management and Data or COMAND for short. This was first introduced in late in the Mercedes S-Class and acts as a center for all audio, telematics and functions, namely car radio, CD navigation with dynamic CD changer, sound system, car voice control and TV receiver.

The can either operate these directly on the COMAND unit in the console and read the necessary messages on the large color or else can transmit instructions the buttons of the standard-fitted multifunction wheel. These buttons can be to control the volume, car radio, CD phone and navigation system The central display in the instrument and the information on the COMAND display in the console are coupled together but can be operated separately. For example, the display can show the graphical instructions (arrows) of the navigation while the front passenger is through the electronic phonebook on the screen.

The technology of the integrated system is based on the same as the Audio 30 APS unit. Here the CD player can be used both as a storage medium for the CD-ROM map and for playing audio CDs. COMAND provides even functions and above all is unique in a color LCD display. On this an additional easy-to-read map of the area and route can be called up by pushbutton. the aid of this map and a crosshair cursor, the can pinpoint and program the destination. A TV can be optionally connected.

TELE-AID alerts the emergency services in an

The TELE-AID automatic emergency system is one of the additional telematics provided for Mercedes customers. means that the system emits an SOS call following an without human intervention, to the rescue services and guide to the accident site. The SOS signal the car is transmitted by mobile phone to an call center. The message of the following information: time, license plate number, model and precise location. On the of this information, the call operators immediately determine the emergency service center and the call.

Like the navigation TELE-AID works with GPS Positioning System), a system of that send digital signals to the vehicle from orbit around the earth. on the accident type, the emergency system is triggered automatically by the standard-fitted crash sensor is also responsible for activating the and seat belt emergency retractors, or by the rollover sensor. The of the C-Class can also send out the call message manually by of a button in the interior of the C-Class. the emergency call, TELE-AID permits a connection to the operations center of the police.

TeleDiagnosis a direct connection to the customer

TeleDiagnosis is the latest telematics for Mercedes customers and is making its together with the C-Class. As a system requirement, the sedan be equipped with TELE-AID. In the of a breakdown, the TeleDiagnosis system contact with the central Assistance Center (CAC) at the of a button. The customer advisers speak with the driver by phone and provide advice and support. At the same time, the automatically sends all necessary to the Center: vehicle and engine year of construction, engine battery voltage, mileage and any fault and warning messages. In the telephone automatically transmits the exact position, so that the engineers of the closest Mercedes or workshop can be directed as rapidly and as possible to the breakdown site. In to establish the voice and data to the CAC, all that is required is to the blue button with the signal on the fixed receiver of the system.

“MB Info” information about Mercedes-Benz

By phone and with the aid of the TELE-AID Mercedes customers can also ask the advisers general questions and advice and information on all subjects to the car. This service is “MB Info”. The phone is stored in the electronic phone of the car phone and appears on the display the label “Info” after a initial period in the operating Subsequently a single press on the button is enough to establish the voice connection.

With the car radio does what it is

The innovative LINGUATRONIC voice system that Mercedes-Benz was the car manufacturer in the world to develop for the of the car telephone does even in the C-Class. Available as an option, it now not controls the most important functions but is also, for the first connected to the audio systems. As a a couple of words from the are sufficient for the radio to seek station automatically, change to the CD track or switch over to mode.

With this Mercedes-Benz is providing a further contribution to traffic safety, drivers no longer have to their hands off the steering to operate the car phone or audio LINGUATRONIC therefore relieves the on drivers, who can now concentrate fully on the and also considerably improves comfort. Only the tone and controls cannot be voice-operated. The of the LINGUATRONIC system is a software that is programmed with for voice recognition and for peculiarities of the voice. Consequently, the system can adjust to the individual speaking of the relevant user. For instance, in it can understand both high and local dialects. The system operates in English, French, and Italian.

Data transfer at the of light

The transmission of sensor measurement data, information, and TV pictures at lightning speed is by three high-capacity databus on board the C-Class. These divide the transmission functions three sections interior, train/chassis and audio/communication/navigation and are interconnected by of interfaces (gateways). The “Class CAN network for the drive train/chassis integrates seven control In the “Class B” network, up to 20 exchange their data. For the time, the control unit for the and TELE-AID emergency call are also integrated in the network. In the on-board electronic system of the controls more than 130 by databus and processes more 850 different items of information for purpose.

In addition to the proven CAN the C-Class also has an optical that uses pulses of to transmit signals. The name of system is the “Domestic Digital or “D2B” for short. Instead of cables, this system fiber optic cables of plastic. In these cables, data and switching signals can at the speed of light. Consequently, connected to the “D2B” ring can transfer much larger of data in a shorter time in the CAN bus: up to 5.6 million bits are per second in the fiber optic representing a transmission rate 60 times faster than CAN in the interior by copper cable. The optic cable therefore many more information in a comparable time, so that the data of a music CD can be transferred perfect sound quality.

Engines and transmissions: More under the hood

By increasing engine displacement, engineers have obtained torque for the entry-level C 180 and the six-cylinder C 240 to make this sedan more nimble and flexible the predecessor model, particularly in the engine speed range. levels of driving enjoyment and dynamics are also provided by the powering the C 200 KOMPRESSOR, which the previous 2.0 liter engine. performance and a high level of are among the special features of the C 320 which replaces the previous C

The two four-cylinder models are powered by the Mercedes engine which, in displacement sizes, is also in the C-, E-, M- and V-Classes as well as in CLK models. at Stuttgart have, however, major engine components and them to suit the installation in the sedan. In addition, the 2.0 liter of the C 180 was provided with a secondary system which significantly the effectiveness of the emission control the engine‘s cold-start phase. All in more than 150 components of the four-cylinder engine were For example:

The cylinder head is by airflow-optimized intake and exhaust with an oval cross-section for volumetric efficiency. A new, compact combustion chamber serves the same purpose.

The camshaft on both four-cylinder now features a special Hall which during cold senses the position of the piston in the cylinder. As a result a significant in the starting characteristics of the cold is achieved.

The timing gears now a special rubber coating helps reduce engine noise.

A newly developed suction-type fan provides the engine with cold air. It the amount of engine cooling to be in the interests of fuel economy and reduction.

The air ducts and the intake were also modified a view to noise reduction. The developed broadband resonator intake noise.

Modern spark ignition coils right behind the cylinder increase the efficiency of the ignition Other features include the platinum spark plugs only need to be replaced 100,000 kilometers.

Using a interface, a new electronic engine system perfects the interaction of transmission and standard-fitted Electronic Program (ESP).

The C 180 offers flexibility and greater performance

the further developed 2.0 liter aspirated engine which 95 kW/129 hp at 5300 rpm, the C 180 the dynamic and agile character of the The increased displacement and refined of the four-cylinder unit provide flexibility and greater performance with the previous entry-level 185 Nm of torque is available from 3500 rpm, cutting the for the sprint from 60 to 120 km/h in gear to 20.2 seconds or by six seconds compared with the model. Despite the increase in output and the approximately 100 kg higher weight, fuel consumption of the C 180 by just 0.1 to 9.3 liters per 100 kilometers overall consumption, provisional

C 200 KOMPRESSOR for dynamic driving in the two-liter class

The two-liter engine with 120 kW/163 hp a dynamic driving experience is pretty rare in this class. In conjunction with its value for money, the C 200 KOMPRESSOR has all the ingredients to assume an outstanding within its market segment. with a belt-driven supercharger, power plant matches the and torque characteristics of a larger engine. With a hefty 230 Nm, the C 200 races from 60 to 120 km/h in 15.1 seconds (in fifth This sedan requires a 9.3 seconds for the sprint from to 100 km/h. These remarkable and torque values do not conflict the engine designers’ commitment to fuel consumption further. On the compared with the outgoing C which developed about 20 per less output and torque, the C 200 uses only 9.5 liters of per 100 kilometers, or a mere 0.1 liters (NEDC overall consumption). with specialists from the company, Stuttgart engineers the compressor further and optimized features which translate audible progress. The power under the hood of the C 200 KOMPRESSOR new engine mounts which the use of an electro-magnetic coupling between the and the charger superfluous. Thanks to new mounting technology, the compressor is quieter in operation.

C 240 with engine displacement for improved

Mercedes engineers have the cylinder diameter of the V6 engine the C 240 from 83.2 to 89.9 ensuring that a total of 2597 cubic centimeters is now While power output unchanged (125 kW/170 this measure actually a torque increase of almost per cent: the six-cylinder unit now 240 Nm at 4500 rpm. It is remarkable how improved engine characteristics in with the good aerodynamics of the affect driving performance: the C 240 exactly 16.4 seconds for the from 60 to 120 km/h and is thus 5.7 quicker than the predecessor with the same number of under the hood.

C-Class 3.2 liter V6 power plant for the time

The C-Class offers greater driving fun when with the powerful 3.2 liter which is regarded as one of the most power plants in its displacement In the C 320, Mercedes-Benz for the first combines the visual and technical of the model with a performance matched by few other automobiles in market segment. Its 160 kW/218 hp and 310 Nm the C 320 from rest to 100 km/h in 7.8 seconds.

All gasoline engines with the strict EU-4 limits

Mercedes-Benz has developed a emission control system to the strict exhaust limits of the EU-4 Directive and the American (Ultra Low Emission Vehicles) This consists mainly of an exhaust manifold, bulkhead and catalytic converters as well as an diagnostics system comprising oxygen sensors. Exhaust measured in accordance with the Directive are 1.0 g/km of carbon 0.1 g/km of hydrocarbons and a mere g/km of nitrogen oxides they are up to 56 per cent lower under the EU-3 Directive is currently in force. Moreover, the quality of these systems that these low emissions constant over a covered of at least 80,000 kilometers. buyers of a gasoline model the C-Class by Mercedes-Benz benefit these exemplary exhaust in that they receive a tax credit of 600 marks (if first occurs before December 2004), with subsequent vehicle tax charged at the reduced of ten marks per 100 cc engine displacement.

New CDI develop up to 43 per cent more

The acronym CDI now adorns the trunk lid on all sedans of the Mercedes-Benz C-Class. It is with the most advanced fuel injection which the common-rail principle plus injection plus four-valves-per-cylinder plus turbocharger plus The result of this diesel guarantees high torque, agility and low fuel consumption the prerequisites for unspoiled driving

Compared with the predecessor the three diesel engines for the offer up to 14 per cent more output and up to 43 per cent more This is mainly due to the use of the VNT charger Nozzle Turbine). The adjustable of the guide vanes inside the ensures optimum exhaust gas at any engine speed. In the lower rev in particular the effect is that of a build-up of charge pressure, volumetric efficiency and hence torque.

With its common direct injection Mercedes-Benz has considerable advances compared the earlier pre-chamber engines not in the areas of driving and noise Further engineering features to the CDI engines in the Mercedes-Benz C-Class

The aluminum cylinder head two spiral induction ports, one of has been optimized for swirl and the for volumetric flow. This to an optimum fuel and intake air particularly under part-throttle

The mixing chamber an integrated exhaust gas recirculation where fresh and exhaust air in a computer-calculated ratio. The valve is via an electro-pneumatic converter.

The intake which upstream of each at first features just one before developing into a system that takes on functions. While one of them is for swirling the fuel-air mixture, the one ensures adequate cylinder when the air flow is high. part-throttle this port is, closed by electrically operated This ensures that inside the cylinders is increased producing more complete

Pilot injection, which significantly to reduce the noise of direct-injection diesel engines. A few before the actual fuel occurs, a small amount of is pre-injected into the cylinder. ignites immediately, thereby the combustion chamber. As a result, the ignites more rapidly, pressure and temperature do not rise so

The C 220 CDI offers a powerful 315 Newton of torque

Thanks to the power hike from 75 kW/102 hp to 85 hp and the extra torque of around 6.4 per the C 200 CDI offers even greater driving pleasure. Particularly is the engine’s enhanced flexibility propels the sedan in 18.0 from 60 to 120 km/h (in fifth taking 7.2 seconds less the outgoing model. With its 105 hp and the powerful torque of 315 Nm, the C 220 CDI even the more powerful C 200 KOMPRESSOR in of pulling power. The diesel sprints from 60 to 120 km/h in 15.0 seconds and achieves a speed of 220 km/h. The fuel of the C 220 CDI, is only 6.2 liters per 100 (NEDC overall consumption).

The C 270 CDI 14 per cent less fuel

Mercedes-Benz C 200 CDI 115hp W203

The C 270 CDI is a agile and dynamic automobile is superior to its predecessor model in respect. With a power up more than 13 per cent the uses almost 14 per cent fuel than the outgoing C 250 a mere 6.9 liters per 100 kilometers overall consumption, provisional

The modern diesel engines of the comply with the emission of the EU 3 Directive.

Electronic monitoring of oil level

The Active Service ASSYST is part of the standard of all engines of the C-Class. On the basis of data, ASSYST calculates the load on the engine oil and works out a servicing schedule for the engine. means that oil change can be increased, depending on the driving and engine load, to up to 30,000 on gasoline models and up to 40,000 on the C-Class diesel sedans.

The electronics that provide with the necessary sensor also make life for the driver: on the Mercedes-Benz C-Class it is no necessary to check the oil level using a dipstick. Instead it is to press a button on the multi-function wheel for the requested information to be on the central display of the instrument While the car is on the move, the system automatically and only informs the if the oil has reached a critical level. on the four-cylinder models C 180 and C 200 KOMPRESSOR is it to manually check the oil level.

Six as standard

With the exception of the C 320 all of the Mercedes-Benz C-Class are equipped as with the newly developed manual transmission. The six-cylinder features the five-speed automatic as standard. The six-speed manual was developed to offer drivers greater comfort while at the time further reducing consumption. The C-Class reaches its top in sixth gear.

The gear-changing is greatly reduced thanks to the use of multiple-cone synchromesh. Engineers paid particular attention to diagonal gear changes, when changing up from into third. Compared the previous five-speed gearbox, effort has been reduced by 25 per cent. At the same time, shift travel has reduced time by an average of 0.3 seconds all in the of an agile and dynamic driving which is made possible by the engines of the C-Class.

Automatic offers even more thanks to one-touch gearshift

is made even easier for who opt for the modern five-speed automatic particularly as this component now even greater convenience. is ensured by the one-touch gearshift Mercedes-Benz first introduced in on the S-Class. Thanks to this the individual driving ranges can be in position D by a slight movement of the lever to the left or right. it to the left means changing moving the lever to the right a higher driving range. If the moves the selector lever to the for longer, the driving range to the gear selected by the automatic

Transmission: five speed one-touch gear shift

the exception of the C 320 all engine variants of the estate are fitted with a five-speed manual transmission. The range-topper features the five-speed transmission as standard from the line. The one-touch gearshift is standard here: the individual ranges can be selected in position D by a movement of the selector lever to the or right. Moving it to the left changing down; moving the to the right engages a higher range. Overrevving is ruled out in because the electronic control only permits a downshift to be when the engine speed is not too Each gear change is in a display on the instrument cluster.

fast no-clutch gear

The SEQUENTRONIC transmission (optional offers a particularly dynamic experience. This is supplied as an by Mercedes-Benz for the models C 180, C 200 C 240, C 200 CDI, C 220 CDI and C 270 CDI. a light nudge of the lever and the changes gear automatically, and precisely, without the need for a pedal. Electrical impulses the driver’s desired gear to a microcomputer, which in turn a special hydraulic unit. The standard mechanical linkages the gear lever and transmission no longer exist with This fast and easy gear changing reduces consumption in the NEDC cycle with the standard six-speed transmission by two to three percent.

The uses SEQUENTRONIC by lightly the gear lever forwards or push it towards the + symbol on top of the lever and the hydraulics will the clutch via the central release and shift to a higher gear at speed. During this the electronic unit takes account the engine speed, torque, wheel speeds and a series of other parameters are important for a precise gearshift. is how the system puts the driver’s change wishes into always in the right order, and the gears one after the other. also applies to changing through the gears, which is by moving the SEQUENTRONIC lever the symbol.

Compared to a standard six-speed transmission SEQUENTRONIC is distinguished by an unit on the transmission casing contains all the extra components the exception of the control unit and the lever:

The hydraulic unit is to the central shift shaft and out the gear changes.

The central bearing operates the clutch: an sensor monitors this movements.

Energy supply from an electric motor and a pump. A special oil reservoir the system with hydraulic

The reservoir module uses to keep the required pressure so that the hydraulics are operational in an

The sensor system monitors the of the shift shaft and determines gear is currently selected. sensor relays data on the speed.

All the SEQUENTRONIC sensor are transmitted to the microcomputer. The control also processes information on the engine speed, engine wheel speed and on the different system functions. The electronic of the automated manual transmission is as soon as the driver’s door is When the ignition is switched on, the unit builds up the necessary in the system, allowing the driver to the gear lever from N, to + as soon as the engine has started. In the of safety, SEQUENTRONIC will do this if the brake pedal is Then, the driver just has to the brake pedal, the clutch and the car slowly rolls forwards and up speed as soon as the accelerator is pressed.

Out on the road, the system out the driver’s requested gearshifts instantly. The automated shift that drivers no longer to worry about the revs, is all done for them by SEQUENTRONIC, automatically intervenes if the engine exceeds or falls below rev ranges. For example, if the driver to change down in time slowing down for a traffic the system automatically selects the gear and disengages the clutch as the car to a halt so that the engine stall. The transmission’s gear can be checked at any time with the in the instrument cluster, which the gear that is currently

Reverse gear can be selected as easily: briefly move the lever backwards from the N to R and the C-class estate will to move slowly backwards as as the brake pedal is released. The will accept the R shift provided the vehicle is either or moving at a speed below km/h.

For getting around in stop-and-go traffic, or at any other if needs be, the sophisticated transmission offers a further plus, the mode. By pressing the gear fully to the left towards the A the SEQUENTRONIC operates fully and uses the numerous sensor to change automatically through the six

Chassis

Dynamic handling as

Further advances in handling, and comfort

New three-link system at the proven multi-link independent axle at the rear

New disk with large performance

Latest driving safety fitted as standard

Mercedes-Benz have spared no effort in existing or designing new axles, and brakes in order to surpass the standards of the outgoing model yet The advances made are immediately exemplary agility, precise stability, extremely accurate excellent rolling comfort, braking performance and safe even when pushed to the

The agile handling of the C-class is to a substantial degree to the new front-axle Wheel location, comfort and response are enhanced by a design Mercedes-Benz are using for the first in this form: a three-link with McPherson struts and steering. In the interests of even suspension kinematics the engineers replaced the lower wishbones to date by two individual link which function as torque and transverse links. In addition to precise wheel location, the benefit of this design is it is better able to compensate for resulting from tire or brake force fluctuations rigid wishbones. The third in the front-axle suspension is the track which connects the transverse gear to the wheels. The spring also have a multiple since they not only and damp the axle, but also assist with locating the wheels. The spring struts of cylindrical coil springs, dampers and large head The standard-fitted torsion bar stabilizer is to the spring struts by a linkage.

The has been extended by 25 millimeters

The of the C-Class is 2715 millimeters, and 25 millimeters longer than its The track widths of the front and axles have also — at the front by six millimeters and at the by twelve millimeters. However, the turning circle, at 10.76 has remained almost unchanged.

steering with modern principle

There are several for using rack-and-pinion steering of the recirculating ball steering used before. The most was undoubtedly the more immediate which is more in line the dynamic character of the C-Class. locating the steering gear in of the wheel center plane in safe understeering performance cornering. However, the system offers benefits in certain of passenger protection and lightweight whereas the recirculating ball gear forms a solid which absorbs no energy in the of a front impact, the rack-and-pinion can be transversely mounted on the deformable bracket and, therefore, not impede the energy absorption And because this system has no of supplementary components such as a arm, steering rod, arm and reinforcing plate, it is some 4.5 lighter than the recirculating steering gear of the outgoing

As previously, a standard-fitted servo-system the steering effort. A new feature, is the easy-operation, speed-sensitive steering, Mercedes-Benz are also offering as an for the first time in the C-Class. Its is particularly noticeable at speeds 100 km/h and reduces the steering as a function of speed. Thanks to an controlled rotary slide which regulates the power the steering effort in urban is reduced by up to 50 percent compared conventional power steering, the result that parking is easy with speed-sensitive

Proven multi-link independent-suspension has been retuned

The multi-link axle, which is still in many respects, made its appearance when the Mercedes-Benz 190 into production in 1983. patented axle design also remains in use in the C-Class in conjunction with the new front the extended wheelbase and the standard-fitted Stability Program (ESP®), it a level of safety, handling and which has never been before in this vehicle The Mercedes engineers have revamped the design of the track hub carriers and rear-axle subframe. New and elastokinematics, based mainly on the use of bearings, ensure even vibration properties and reinforce the understeering self-steer effect, also guarantees a high of handling safety. All the engine of the C-Class, with the exception of the C have a torsion bar stabilizer on the axle. It is directly attached to the body. Springing and damping of the axle are provided by coil and single-tube gas dampers with rubber mountings.

Drivers who a particularly sporty driving can order their C-Class sports suspension, in which the body is lowered by 15 millimeters at the and rear axles, as an optional for all lines and engine versions. The travel is 20 millimeters shorter on the axle and ten millimeters shorter on the axle with the sports tuning than in sedans standard suspension. The spring are up to 21 percent higher. Furthermore, the Suspension” option also 16-inch light alloy and 225/50 R 16 wide tires for all

High-performance braking system can with any situation

Mercedes have again made advances in the field of brake too particularly in terms of braking and braking comfort. Thus, all versions are now manufactured with front disk brakes diameter has been increased to 288 and thickness to 25 millimeters on the four-cylinder and diesel engines. In the C 240, C 320 and C 270 CDI the diameter of the front disk is 300 millimeters, while the disk measures 28 millimeters. Thanks to large size and the newly brake calipers made of nodular cast iron the disk brakes on the front of the C-Class feature above-average reserves even under loads.

Another new feature is the stud-like castings in the ventilation of the brake disks, where replace the cooling fins previously. The special design of components, which link the two ring halves of a brake ensures an optimal flow of air and therefore increases the gray iron disks’ shape under thermal load. In terms this means the of brake judder, which occurs because of deformed disks, is effectively prevented by modern system. The rear of the C-Class is fitted with disk brakes with a of 278 millimeters (C 240 and C 320: 290 millimeters) to safe deceleration. Here the engineers use fixed-caliper brakes a twin-piston system. The new aluminum booster for the C-Class is a uniform 7/8 for all engine variants which that it is approx. 15 percent powerful than in the outgoing

Advanced control systems for safety

Like all the latest passenger cars, the C-Class, is fitted with the world’s and most efficient handling systems as standard. They the risk of skidding when keep the sedan safely on when braking, ensure accelerating from rest on surfaces and shorten stopping in emergencies. This efficient is an important element of the safety of the Mercedes-Benz brand (see on page 36) and actively helps to road accidents:

Electronic Program (ESP): Thanks to a of sensor signals, the Electronic Program detects hazards far and faster than even the experienced driver. The system can intervene in a highly controlled to stabilize the vehicle. While the car is in the ESP computer constantly compares the actual handling with the set points. If the car diverges from the “ideal line”, ESP intervenes rapidly and returns the car to the right in two ways: by delivering precisely braking pulses to one or more and by reducing the engine torque. ESP also stabilize the C-Class in the of skidding caused by extreme maneuvers, ice, wet, or other unfavorable road The latest ESP generation is particularly it works extremely smoothly of its almost imperceptible responsiveness. It is fine tuning in particular demonstrates the great experience Mercedes’ engineers have as of this innovative system.

braking system: ABS prevents the from locking when in an emergency and works just as on dry asphalt as on wet or icy roads.

Acceleration control: The sensor signals by the anti-lock braking system are available to the acceleration skid system (ASR), which is part of the Electronic Stability (ESP). ASR helps to prevent spin at the drive wheels accelerating from rest or in or for general driving in the event of for example.

Brake Assist: This which Mercedes-Benz developed to stopping distances in emergencies, is one of the functions included in ESP in the C-Class. Assist (BAS) springs action if the driver brakes too or gently in critical situations. In cases the system automatically the maximum brake boost fractions of a second, thereby shortening the car’s stopping quite considerably by up to 45 per cent.

The of wheels also meets the of sporty drivers

The C 180, C 200 C 200 CDI and C 220 CDI in the Classic and Elegance lines are as standard with 195/65 R 15 tires on 6 J x 15 wheels. The Avantgarde stands out with its standard-fitted wheels and 205/55 R 16 tires. combination is also the standard for the five- and six-cylinder models (C C 320 and C 270 CDI) in all the lines.

The C-Class even more dynamic the sports suspension in conjunction the “Light alloy wheels in design” option. 225/50 R 16 are fitted to 7 J x 16 wheels on the front and to even wider 8 J x 16 light wheels on the rear axle perfectly underlines the car’s handling. It is also possible to mixed 17-inch tires on AMG light alloy wheels in with the sports suspension: R 17 (7.5 J x 17) at the front and 245/40 R 17 J x 17) at the rear.

Safety

Real-life in six stages

he technical safety of Mercedes passenger cars is defined not only by the various specifications laid down by international bodies but also by the of in-house accident research. the term safety will in mean more than crash safety: more ever before, the theme of is governed by an integrated approach covers the whole ground, with questions of accident by means of electronic assistance and ending with the fastest rescue of the vehicle occupants a crash. The C-Class is an outcome of pioneering “Real-Life Safety which essentially consists of six

Danger warning

Sensors on the and bodywork monitor the car’s characteristics. On reaching the limits of dynamics, a yellow warning lights up in the cockpit.

Accident

Standard-fitted assistance systems as ABS, Brake Assist and automatically enter into in critical situations, thereby the driver to keep everything control.

Minor knocks

The energy of minor bumps at of up to 15 km/h is absorbed by the bumpers and boxes in the front-end module. The reels on the seat belts are Sensors monitor the severity of the and prevent the airbags being until their supplementary effect is actually needed.

In a severe collision, robust in the front, side and rear absorb energy and distribute the forces over a wide The belt tensioners are activated. on the severity of impact, the front initially inflate less fully, in line with need, so that the optimal effect is assured. In a side-on the occupants are protected by sidebags in the doors, combined with For the front passenger seat, the seat occupancy and child recognition system prevents the front airbag, belt and sidebag being activated if not needed. The fuel supply to the is cut off.

Occupant protection

In the of even greater danger to the occupants, a second inflation for the front airbags is triggered. At the time, the belt force are also activated.

Emergency

After an accident, the doors are unlocked. The TELEAID emergency system (optional) alerts the service and guides it to the accident The hazard warning lights are on.

Front-end impact: occupant in three stages

In order to into account all possible conditions, an integrated approach to design is required. The C-Class is of this fact: in a front-end depending on the severity of impact, a protection system enters action, with due attention to the aspect of cost-savings in accident and the typically high Mercedes for occupant protection:

Up to a collision of 4 km/h, the foam elements in the absorb the impact energy, so the metal panels behind undamaged.

Up to a collision speed of 15 km/h, the impact energy is by the newly developed front and the two crash boxes made of an high-strength dual-phase steel.

At a speed of more than 15 the robust side members in the structure come into own and absorb the impact energy. The is distributed to four mutually zones, as follows: via the aluminum of the front module, which the impact forces of the offset to the side not directly involved; via the members, which extend far to the (behind the crash boxes); via the sectional panels above the arches and via the front wheels, are supported on special impact-absorbing in front of the side members panels), thereby transferring forces to the body’s side Another important feature is the developed ellipsoid firewall, is joined to the front side and spreads the impact forces a wide area.

Front two-stage inflation dependent on of impact

The front airbags of the also adapt to the specific situation and thereby provide more effective occupant The era of these innovative adaptive systems began in 1998 in the S-Class: the Stuttgart-based auto has now further developed this and for the first time is providing the with two airbags that in two stages as a function of the severity of In other words, like the structure of the sedan, the restraint is not solely designed to respond to collisions but also for the first takes into account the protective functions required for low to impact forces.

The technical behind this system is both the driver’s and front airbags are fitted with gas generators. If the sensor system a minor front-end impact, it only one chamber of these units, so that the airbags are partially filled. Consequently, the catch the occupants “softly”. to accident research, this is especially advantageous in collisions in the range between 20 and 35 km/h. If the sensors register a higher load, the electronic control also activates the second of the inflators, and the airbags are fully Depending on the severity of impact, second airbag stage is within only 5 to 15 milliseconds of the

The adaptive airbag system of the sedan includes a sensor that decides whether or not to the protection system. For example, the belt tensioner and the sidebag on the passenger’s side are deactivated if the passenger seat is unoccupied. A mat in the seat cushion provides the information to the electronic control If the car owner installs a “reboard” safety seat from the accessories range, special in the front passenger seat data with a transponder in the of the child seat. The airbag system therefore recognizes a reboard child seat has fitted and immediately deactivates the on the front passenger’s side, it is not required in these cases. On the hand, the belt tensioner, and windowbag remain activated.

robust protective zone for the in a side-impact crash

The importance of impact protection for the safety of modern passenger cars is to increase. According to accident the proportion of side impact in traffic accidents involving to car occupants has more than since 1985 just 44% of all car accidents with fatal are now in the side impact category. engineers have responded to practical findings with a package of measures, which, the front occupant protection is primarily geared to actual situations. It is effective at three

In the floor area, reinforced rocker panels transfer the forces to two robust side on each side under the seats and to a full-width crossmember the rear seat. The center reinforcements also improve the of forces between the front

At medium height, the occupants are by laterally stiffened doors in the side panels and with sectional reinforce-ments, robust hinges, and also by the extra-strong of the seats and backrests. A square-section under the dashboard also lateral support.

In the roof intrusions are kept to a minimum by the A, B and with their full-height construction and by a reinforced roof which is again of 3-shell

The highly robust occupant which provides optimal in front-end and side impact is also highly effective in the event of an offset rear-end at high collision speeds. The load-bearing member structure and the developed rear end module similar functions to the comparable at the front and are geared to actual processes.

Sidebags and windowbags as

Another important example of the Safety Concept of the C-Class is by the standard-fitted windowbags that already proved their effect in the Mercedes S-Class, and flagship CL Coupe models. The of these special airbags is on the results of updated accident on the risks of injury in side collisions. Scientists found these accidents involved a range of angles of impact, so the movements forced upon the car could differ vastly, limiting the protective effect of simple solutions.

Consequently, in the of experts, an airbag covering as an area of the side of the car as possible is in order to provide optimal to the heads of the occupants in particular at front and rear in the many crash configurations. The result is the This special airbag the requirements of accident researchers and excellent results even in the impact crashes that from the standard right-angled used in most crash conducted by international test The airbag consists of 9 chambers a total volume of 12 liters. a crash, it inflates to span a curtain from the front to the roof pillar of the interior.

the sidebags particularly protect the area, the windowbags prevent the head striking the side roof pillars or roof In other words, sidebags and belong together. Consequently, fits sidebags as standard to the doors of the C-Class and offers as options for the rear.

Front for the driver and passenger, door-mounted and standard-fitted windowbags are all part of the restraint system which maximum occupant protection at all
