2002 Mercedes-Benz F400 Concept news, pictures, and information

DaimlerChrysler is exhibiting a concept study at the 35th Motor Show: the F 400 Carving is a vehicle packed wîth systems designed to give the of tomorrow and beyond substantially active safety, dynamic control and driving pleasure.

The attraction in the F 400 Carving is a new system varies the camber angle on the wheels between 0 and 20 degrees, on the road situation. Úsed in wîth newly-developed tyres, it 30 percent more lateral than a conventional system a fixed camber setting and tyres. This considerably active safety, since lateral stability equals road adhesion and greater stability.

Active camber boosts the research vehicle’s lateral acceleration to 1.28 g, that the concept study current sports cars by 28 percent.

The active camber in the F 400 Carving paves the way for an equally new tyre concept. When the car is cornering, the outer wheels inwards, leaving only the area of these tyres in wîth the road. This of the tread is slightly rounded Meanwhile both the tread and the rubber blend have specially selected to ensure dynamic and extremely safe When driving straight however, it is the outer areas of the that are in contact wîth the These areas have a car tread pattern, offering high-speed and low-noise performance. Two concepts therefore come to in a single tyre, thanks to camber control.

The research ‘Carving’ epithet symbolises the new evoking images of the high-speed sport in which adepts sharp turns on a specially-shaped ski.

Less risk of and shorter emergency stopping The F 400 Carving is something of a mobile laboratory for the Stuttgart-based automotive They will be using it to the undoubted further potential of new chassis technology: besides excellent directional stability cornering, the new technology ensures a higher level of active in the event of an emergency. By way of example, if is a risk of skidding, the wheel is in-creased by an appropriate degree. The gain in lateral stability enhances the effect of ESP®, the Stability Program. If the research car to be braked in an emergency, all four of its can be tilted in next to no time, shortening the stopping dis-tance 100 km/h by a good five

Electronic §teering, active system and light from fibres

In addition to active control, the F 400 Carving research car is wîth other forward-lòòking and chassis systems, including a system. Sensors pick up the §teering inputs and send information to two microcomputers which, in control an electrically driven gear. The DaimlerChrysler engineers charted new territory when it to the suspension tuning, and introduced a an active hydropneumatic system optimises the suspension and shock in line wîth the changing on the road, all at lightning speed.

The F 400 is also the showcase for a totally new of lighting technology developed by the researchers: fibre-optic lines are to transmit light from lamps beneath the bonnet to the headlamps. This technology out by virtue of its high perform-ance and space-saving design. Additional positioned on the sides also on when the car is cornering.

Exciting symbolising innovation and emotion

The F 400 is an exciting and harmonious blend of and design. The shape of the sports car – its distinctive wing profiles – the necessary room for the wheels to when the active camber is at work during cornering at the same time, emphasises the and highly-adventurous nature of this study. In order to reflect the car’s high-quality driving the de-signers opted for a speedster – incorporating an extended bonnet, a wîth an extremely sharp a short tail end and an interior for two.

The of the F 400 Carving: Exciting Mix of Innovation and

• Forward-lòòking technology wîth design appeal

• Speedster for supreme driving pleasure

• lines symbolizing superlative dynamics

• Interior wîth seats and weatherproof materials

The F 400 design team focused on two lending shape to leading-edge and giving innovations real appeal.

A great deal of was required in order to harmonize the and the design. To put it another way: it was a job like no other. The F 400 designers the unique chassis technology a nut to crack. They had to come up a concept that allowed the enough room to move cornering wîth active control on the one hand, whilst that the car also cut a good wîth the wheels in the normal on the other.

Taking these as the starting point, a multinational was launched about two years inviting young designers the Mercedes studios in Germany, and the ÚSA to come up wîth ideas. A of exciting suggestions came in, from utopian supercars to fun-cruisers and from four-seater to pure driving machines one-man cockpits.

This stage of development became as the ’emotional phase’ and proved in determining the scope of the F 400 Carving design potential and in properly the design process. Indeed it was an necessity since there can be no that, besides requiring know-how, designing such a is all about emotions: a passion for a fascination wîth technology and an for dynamic and enthralling motoring.

And vehicle concept could and more aptly symbolize aspects than an open-top car? A completely open-top car — a speedster wîth an extremely flat and low-slung hood, a short tail an interior tailor-made for two. a whole host of stylish that immediately stir the and reinforce the car’s message: the low-slung air intake in the front the sharp rake of the windshield, the exhaust pipes and the distinctive bar behind the seats.

Exterior: the of dynamics Whichever way one looks at it, whatever angle, the speedster’s is like that of a perfectly and superbly conditioned athlete. The is structured by wing-like sections powerfully span the wheels, drawing them into the body concept, yet without their freedom of movement. wing sections fore and aft of the reinforce this effect, the wheels the dominant focus of when the car is viewed from the

The design team also used the distinctive wing to give the F 400 Carving a characteristic making the headlamps an integral of the wings and using the light to form two ‘eyes’, decisively the sports car’s enticing This stylistic detail is thanks to lighting systems state-of-the-art fiber-optic technology, conventional headlamps are simply too to be incorporated in the limited space in the wing sections.

And, of the two-seater’s face would not be without the three-pointed star, positioned in time-honored Mercedes car tradition. It forms the focal of a further important design that stretches centrally the engine hood, evoking of the unmistakable arrow-shaped nose of the team’s Silver Arrows. particular detail is well on the way to a classic Mercedes-Benz sports having already graced the SLR and Vision SLA sports car studies.

the most striking feature of because they are so steeped in the gullwing doors have to symbolize the Mercedes-Benz brand. It is now 50 years since the first Gullwing created a sensation, the beginning of the SL legend. The F 400 designers this feature and reinterpreted it in the of contemporary design and technology, that the idea is just as and exhilarating now as it was all those years The research car’s gullwing are not attached to the roof as they on the original 300 SL. Instead, they upward 60 degrees thanks to joints, supported by gas springs.

The muscular contour of the door into a sweeping, powerfully profile which forms a line stretching back as far as the tail end, where it as a fender for the rear wheels. The part of this section the rear lights, in the same way as its at the front incorporates the headlamps. The prism lenses enable the tail lights and brake to effortlessly blend in wîth the design concept and, cast an extremely impressive on things.

Interior: high-tech in packaging

A look inside the reveals another major theme of the F 400 Carving: technology in its form. Technology that on the essentials, on what motoring was all about and, therefore, on absolutely central to this Nothing more, nothing

Admittedly, this initially of purism, a totally stripped-down machine. But a closer look reveals all: the perfect the very best materials and a for detail. The designers at the Mercedes – in Como, northern Italy and southern Germany – devoted to the task in hand, giving the a characteristic appearance that on classic aspects of bodystyling and Nowhere is this more than in the ‘wing’ theme, the panel being a perfect in point: there is no firm link between the panel and the tunnel. It seems to be ‘floating’ in like some majestic and thus appears extremely and almost delicate.

The idea of in its purest form is most exemplified by the transmission tunnel, has the shape, color and texture of a transmission bell. As such it the racing car cockpits of the twenties and an era when drivers had to make do bare metal and little The simple sliding controls for the and the heater, the metallic lever for the transmission and the oval ventilation above the transmission tunnel all these images of bygone yet behind each of these styling features lies technology.

Passengers in the F 400 Carving are by carbon seats in which immediately feel at one wîth evocative car and its technology: man and machine in perfect harmony. The seats superlative lateral support and can be adjusted, despite their design. The multi-layered fiber means it is possible to vary the inclination without the need for or hinges — a small mechanism is all that is required. wîth spring and damper beneath the seat, the multi-piece ensures effective vibrational for good seating comfort.

all-weather performance

Choosing the cover fabrics for the F 400 Carving the designers wîth a particularly challenge: the two-seater is a pure and so it was essential that the interior be literally windproof and weatherproof. out wîth breathing yet hardwearing fabrics, the experts developed an range of cover materials for the vehicle. Thanks to a special coating, the materials are water-repellent and extremely suitable for this Furthermore, the upholstered sections of the are designed to be easily removable, so the owner can leave them in the if they need to dry.

In the F 400 Carving is an ‘active experience’ car masters extreme situations and safely. This is highlighted not by the new chassis technology, but also by interior features and by the two-seater’s styling concept. Technology and are uniquely and inextricably linked. New are not just supremely fulfilled, are also made an integral of the overall design and the emotive

The of the F 400 Carving

• Mobile research wîth leading-edge technology

• control the wheel camber in accordance wîth the road

• Úp to 30 percent better lateral when cornering

• Tires wîth asymmetrical pattern and two friction zones

• New system for §teering and braking

• active suspension and damping

• Carbon fiber body, composite brakes

• New headlamp wîth fiber-optic technology

The research car gives us an insight the future: the F 400 Carving follows in the of other vehicle studies as the F 200 Imagination and F 300 Life-Jet, which new §teering and chassis concepts in and 1997 respectively: ‘drive-by-wire’ and roll control’ were two of the concepts central to these research projects. The research and scientists at DaimlerChrysler have these ideas in the F 400 Carving and are to unveil an entirely new system further enhances active and dynamic handling and gives an more exhilarating driving

20-degree wheel camber for and reliable cornering

The ‘Carving’ already hints at the capabilities of the technology in this research Each time the car enters a or bend, two of its wheels tilt riding on a tire tread has been specially optimized for and has a high friction coefficient for directional stability and road The dynamics are reminiscent of the movements by alpine skiers using skis.

The computer- controlled in the F 400 Carving varies the camber on the outer wheels by between 0 and 20 when the car is cornering. The inner and the vehicle body remain in normal positions.

‘Active control’ is the culmination of a research spanning several years. It all wîth computer simulations and tests. But now the time has come for out on the road.

The F 400 Carving is something of a research laboratory for the Stuttgart-based engineers. They aim to use the open-top to further research the potential of chassis systems and to open up new in chassis technology for the passenger of the future. Initial test and measurements have delivered encouraging results.

Compared to a car chassis, the active camber in the F 400 Carving enables up to 30 percent lateral stability and 15 percent longitudinal forces. The numbers up these claims: whilst the lateral force on the wheel is about 6200 Newtons the camber is zero degrees, figure rises to 6900 when there is a negative of 10 degrees and as high as 7800 when the negative camber is 20

Thanks to the high level of stability on the outer wheels cornering, lateral acceleration in the F 400 is up to 28 percent higher than in cars that rely on chassis technology. When the wheels of the F 400 Carving are tilted by 20 degrees during cornering, the achieves a maximum lateral of 1.28 g.

This impressive is not just an indication of high dynamics and sporting agility, it signals a substantial improvement in safety, particularly in emergency such as cornering at (excessive) or sudden obstacle-avoidance maneuvers. The car remains more directionally than a car equipped wîth chassis technology. What’s it does so for longer and at a higher

Tires: the concept of asymmetry The are a major contributing factor to results: active camber enables a totally new concept for the first time and without combines the benefits of a passenger car wîth those of a motorcycle Asymmetry is the principle behind new tire technology, jointly by engineers from DaimlerChrysler and the tread pattern, tread and contour are all asymmetrical.

The most feature on the inside of the tire is the tread which ensures handling when cornering. The shoulder of the tire has a tried-and-tested car pattern, offering excellent stability and low road noise. For the time, the experts have in harnessing the benefits of an established theory, according to which, at camber angles, a tire a curved tread can transmit lateral forces than tires. The asymmetrical tread is possible by the fact that the of the tires only come contact wîth the road the active camber control the outer wheels inwards cornering. This leaves the one clear objective to focus on harmonizing and optimizing the inner of the tires: superlative cornering

Rubber blend: tire wîth different friction

The rubber blend used for the F 400 plays an equally important since the softer inner-tread enable even greater of the forces – i.e. even road adhesion – when These ‘high-friction compounds’ are not suitable for car tires as the soft blend is more susceptible to than the conventional rubber used. Therefore the new tire not normally achieve the mileage of today’s tires are capable.

The camber control in the F 400 Carving up for this short-coming: thanks to innovative technology, the softer of the tires only come contact wîth the tarmac the car is cornering and so do not wear as quickly. In the rubber compound the experts for the outside of the tire is much having been optimized regard to longevity, straight-line and road roar.

In other thanks to its asymmetrical contour and rubber blend, the newly tire provides the answer to a unresolved conflict of aims: cornering safety and superlative dynamics on the one hand; high and superb straight-line stability on the For the first time, therefore, two concepts come to fruition in a tire, thanks to active control.

Mercedes-Benz F 400 Carving

Tire size: two on one rim

Tires need a sufficiently contact patch in order to a high level of lateral when cornering, however. And presents a problem: the greater the camber, the smaller is the active patch, at least as far as standard are concerned. Recognizing this one of the chassis technology used in the F 400 the DaimlerChrysler engineers developed a new of wheel wîth two different 17 inches on the inside – the part of the that is in contact wîth the when cornering – and 19 inches on the On the one hand, this ensures the research car only runs on the section of the tire when straight ahead whilst, on the hand, the smaller inner provides the largest possible patch when the car is cornering.

In terms, the tire size is R 19 tires on the outer shoul-der and R 17 on the inner side.

Highly-promising

Active computer- controlled adjustment and asymmetrical tires brought the DaimlerChrysler engineers a step closer to achieving one of primary objectives: enhancing exemplary levels of active and driving dynamics for the benefit of models. But this is just the of what promises to be an extremely research project: alongside lateral acceleration and exemplary stability, this innovative provides a whole host of on-road benefits:

If there is a of skidding, due to understeer or oversteer, the briefly tilts one or more of the by a precisely calculated amount, boosting the lateral forces and the car. This means camber control has the potential to the effect of ESP®. Coupled electronically controlled §teering, allows automatic §teering this can greatly reduce the of skidding.

In the event of emergency all four wheels on the research car at lightning speed, leaving the insides of the tires – wîth rubber-compound tread – in contact the road. This reduces the distance from 100 km/h by a five meters.

If there is a of aquaplaning, the system is capable of the tire contact patch by an amount. A wheel camber of five degrees is enough to the desired effect: a substantial in the risk of aquaplaning. A new breed of system, currently under at DaimlerChrysler, detects the water on the road surface and sends the values to the ECÚ at the heart of the active control, enabling the system to adjust the tilt of the wheels to the road conditions.

Asymmetrical tires would prove beneficial in winter as the rubber blend and tread combine to provide extremely traction as well as short distances and superlative directional To ensure safe driving on or ice, the driver can tilt the at the push of a button, thus the car to run solely on the insides of the tires, for road adhesion.

Tilting hub wîth hydraulic cylinders

computer- controlled camber is possible thanks to two-piece hub and a powerful hydraulic system. hub carrier consists of one tilting and one rigid section: the wheel compo-nents of a double-wishbone suspension are attached to the rigid inside whilst the wheel bearings and the caliper linkages are located on the outside sections. During piston rods in dual cylinders press against the hub-carrier sections on the outer causing them to tilt at the bottom. In this way, the camber can be varied between 0 and 20 depending on the road situation.

The rear axle on the F 400 Carving is in much the same way as the front the variable-length axle shafts the only major difference.

At the of the hydraulic system is an axial pump wîth a working of up to 200 bar. Servo valves on the dual cylinders regulate the oil to control the degree of cylinder and extension. If the driver adopts a driving style, rapid movement is required and in this the pump receives assistance a hydraulic pressure reservoir. A function is also provided: shut-off valves interrupt the oil to the hydraulic cylinders and use the pressure in the system to set the wheel camber to zero degrees.

Steer-by-wire and

Active camber control, as in the F 400 Carving, represents a major forward in chassis development for car models. Even in its own right. But the engineers are taking things a further, marrying this to a whole host of other, pioneering systems. The key to it all is drive-by-wire. The F 400 wîth mechanical connecting such as the §teering column, all the shafts and joints that go it, and the linkage between brake and brake booster. In their are wires which transmit the §teering or braking inputs by electronic means.

Steering: The §teering wheel is equipped two inductive angle sensors pick up each movement of the wheel, convert the measured into an electrical pulse and the signal to the research car’s via data line. The computers these and other current signals, using the data to setpoints for the front axle angle. In critical situations, the system can also override the §teering inputs, to keep the car on an even keel. Two electric which are directly connected to the §teering, move the wheels of the F 400 This is why the automotive researchers to an ‘electric rack’ – a new feature they developed together the §teering experts from Lenkungen GmbH. Each motor generates half of the torque. In the event of a malfunction, one of the alone can assume total for the §teering functions. This is a redundant system, designed to maximum functional reliability. the research car’s power is based on a dual-system concept: a standard (12-volt) on-board supply, the F 400 Carving also has two systems which are primarily for the electronic §teering.

Brakes: is already very much a at Mercedes-Benz. The Sensotronic Brake (SBC) high-pressure brake on the following principle. When the pedal is depressed, an electrical is produced which is forwarded to a A sophisticated sensor system that the microcomputer receives a feed of data about the driving dynamics. The electronic can therefore calculate and modulate the pressure for each wheel, to the situation in hand. The end result is enhanced braking safety cornering.

Alongside Sensotronic Brake the braking system in the F 400 Carving a further technical highlight really sets it apart: the discs (330 millimeters in are made of carbon-fiber-reinforced ceramic, a material that is capable of extreme temperatures of between and 1600 degrees Celsius. It is around a third lighter cast iron.

Suspension and next-generation ABC

The new active hydropneumatic suspension system also the research engineers entering territory: the F 400 Carving is being to test this possible to future generations of the active system which is currently as standard in the Mercedes S-Class, and SL-Class models.

In contrast to the Active Body Control system, in which active of the forces between the vehicle and the wheel is performed by adjusting the action, the active hydropneumatic influences both the suspension and the adapting them at lightning to the situation in hand. The benefits of system include an even level of active safety and ride comfort.

Engine and Mercedes technology wîth new solutions

Beneath the engine of the F 400 Carving is a state-of-the-art 3.2-liter V6 a tried-and-tested unit installed in other Mercedes model This six-cylinder engine from the standard production in just one respect: the research have equipped it wîth a dry lubrication system which a constant supply of oil to the powerplant, when lateral acceleration is high.

The sequential gearbox in the car is also a standard Mercedes-Benz model. Only the SEQÚENTRONIC are different: in the F 400 Carving, the driver gear in racing-car style – selector buttons on the §teering

Xenon light from optics

Equally new is the headlamp of the F 400 Carving. For the first time, is using state-of-the-art fiber-optic to transmit the light produced by the lamps. These optical-fiber made up of thousands of individual strands, enable physical of the light source and the headlamps an advantage that primarily the sports car’s front-end since the headlamps only up a very small amount of This therefore allows an flat and low-slung front.

The for main and dipped beam is in two cylindrical casings beneath the hood. Each contains a lamp, and the light given off by lamps is concentrated by elliptic The reflector focal points the light into the fiber-optic which, in turn, ensure transmission of the light to the headlamps. lens systems in the headlamps the light to illuminate the road. In the F 400 Carving has two side-mounted lights for These fixed-position halogen come on when a certain angle is reached. They can be activated by a button, for use as fog lamps.

A design is also the hallmark of the powerful LEDs generate the which is then dispersed by of prism lenses.

Vehicle lightweight carbon fiber

The two-seater’s body is made carbon-fiber-reinforced plastic (CFRP). tried and tested in the world of One motor racing, its chief are minimum weight and maximum It weighs in at about 60 percent than steel, making the of the research car 100 kilograms lighter. The engineers use an intelligent three-material mix for the F 400 chassis: steel, aluminum and fiber (CFRP).
