Mercedes A-Class UK-Version

has started completely afresh for the generation of its compact front-wheel A-Class. The latest Mercedes-Benz is based on all-new vehicle and assembly techniques and introduces and more dynamic design greater emotional appeal. It is by an updated family of turbo-charged petrol and diesel engines up to 211 hp with CO2 emissions as low as 98 g/km.

The new is available with Mercedes-Benz’ double-clutch seven-speed automatic (7G-DCT), and the range also the company’s policy of ensuring as many people as possible the protection of advanced safety with the innovative Collision Assist headlining a comprehensive of active and passive protection fitted as standard.

The new Mercedes-Benz is the second model in what eventually become a family of front-drive cars from which began with the B-Class . But while the B-Class is on family usage, providing the of a much larger saloon a compact-car footprint, the A-Class has a dynamic role to play, as is in its dramatic styling.

Mercedes-Benz has introduced a new 2.0-litre direct-injection petrol engine to its Mercedes-Benz range generating 211 hp — to propel the car from zero to 62 mph in 6.6 and on to a 149 mph top speed. This is standard the exclusive range-topping Engineered by AMG as is the 7G-DCT double-clutch automatic along with AMG-inspired trim, equipment and chassis

2013 Mercedes-Benz A-Class

Two new diesel engines also their debut in the third-generation giving the car potential fuel of 74.3 mpg with CO2 emissions to 98 g/km.

At the other end of the spectrum, the 220 CDI engine generates 170 hp and 350 Nm of torque. In with the standard 7G-DCT it accelerates the A-Class from mph in 8.2 seconds. It meets the EU 6 emissions not due to come into force 2015, while posting a fuel economy of 64.2 mpg and CO2 of just 115 g/km, demonstrating with the new Mercedes-Benz A-Class, and efficiency are not mutually exclusive.

and engineers are rarely given the of a completely blank sheet of when starting work on a new yet that is precisely the opportunity engineers were given for the new Longer, wider and lower the previous two versions, the latest is a more emotive and dynamically car that’s little changed the radical Concept A-Class a wildly enthusiastic reception at the Shanghai Auto Show.

It is a and highly sculpted five-door model, now based on a monocoque rather than the sandwich assembly of the previous two generations. not only dramatically reduces the height of the car, but it also the seating position of the occupants by 174 mm, in turn brings down the of gravity by 24 mm to allow much dynamic and agile driving These are even more in the 15 mm lower AMG Sport and specifically Engineered by AMG versions.

The exterior mixes sharp edges and drawn convex and concave which seem to constantly with the angle of the light, along the sides. The long, front leads into a V-shape, culminating in the radiator with the central Mercedes-Benz between double slats, or a slat dividing a unique grille in the Engineered by AMG version. The and the light functions within are key elements of the design concept.

The emphasises the class-leading aerodynamics of the new A-Class, with its drag of Cd 0.27. This is especially in the smooth arc of the roof, which in a flat edge, and a spoiler conveniently hides the aerials. The is another interplay of convex and surfaces which further the interaction between design and the surface of the tail lights airflow around the car through break-away edges.

The interior of the represents a dramatic step in the quality of materials used, as as the consistency of design. The front of the adopts an aviation-inspired theme, the dashboard shaped like the of an aircraft and the round air vents of jet engines. Meticulous attention to is apparent everywhere, from the touch’ real metal trim embellishers to the free-standing screen with a black lacquer-look front panel and a silver frame.

The rear generous room for three despite looking as though it has two individual seats. A 341-litre area can be expanded to 1,157 with the rear seats In all models the seat backrests are 2/3:1/3.

Altogether, there are direct-injection turbo-charged engine in the new A-Class, all characterised by high outputs, flexible performance to strong torque across a rev range, outstanding efficiency and refinement.

In addition to the new 211 hp 2.0-litre unit (A 250 BlueEFFICIENCY) and the new 109 hp 1.5-litre (A 180 CDI and 170 hp 2.2-litre (A 220 CDI BlueEFFICIENCY) turbodiesels, are two further petrol units (A 180 and A 200 BlueEFFICIENCY) and two more diesels (A 180 CDI 7G-DCT and A 200 CDI BlueEFFICIENCY), which introduced with the latest All engines feature ECO start/stop as

The A 180 BlueEFFICIENCY is powered by a 1.6-litre 122 hp while the A 200 BlueEFFICIENCY uses a 156 hp The diesel engines are 1.8-litre a 109 hp option is fitted in conjunction the 7G-DCT transmission in the A 180 CDI BlueEFFICIENCY, and a 136 hp in the A 200 CDI BlueEFFICIENCY.

A six-speed manual is standard with the A 180, A the 1.5-litre A 180 CDI and the A 200 CDI, while the A the 1.8-litre A 180 CDI and the A 220 CDI have the 7G-DCT This is an option with the A A 200 and A 200 CDI. Fuel consumption has reduced by up to 35 per cent compared the preceding models, despite power increases.

The petrol are all-aluminium M 270 turbo-charged direct-injection four-cylinder units. They are versatile engines which are being phased into Mercedes-Benz models to help down fuel consumption and They employ technology introduced in 2010 with the BlueDIRECT V6 and V8 engines for the S-Class . The process is based on third-generation direct- injection technology highly precise, multiple

With the exception of the new 1.5-litre now in its sixth generation and specially by Mercedes-Benz for use in the A-Class, the diesel are developments of the OM 651 fourth-generation 2.2-litre unit premiered in 2008. then the OM 651 has been setting for performance, torque, economy, and smooth running. It is in more use than any other Mercedes-Benz engine.

The instantaneous response of the and the slick operation of the six-speed and triple-mode (Economy, Sport and 7G-DCT transmissions in the new A-Class is by the agile chassis, which a four-link rear axle, power steering, powerful disc brakes and advanced assistance functions such as tuned ESP® Electronic Control.

There are three suspension tunings, with a set-up for standard, SE and Sport a sportier 15 mm lower arrangement for AMG variants and the ultimate AMG-tuned in the A 250 BlueEFFICIENCY Engineered by AMG.

All from the more dynamic new and lower centre of gravity of the Mercedes-Benz A-Class. During the engineers made intensive use of the simulators at the Mercedes-Benz development in Sindelfingen to create a digital of the driving dynamics of the new A-Class. enabled them to achieve the balance of agility, nimbleness, and comfort required for each before a single prototype had built.

In keeping with new model introduction from the latest A-Class extends the afforded by advanced safety to as many people as possible by features that are the preserve of the most expensive cars some brands.

In the A-Class, starts with an extremely body shell incorporating areas of high-strength and ultra-high-strength for rigidity with lightness, and the innovative radar-based accident system, Collision Prevention which is fitted as standard. gives visual and audible to alert a distracted driver to the of a nose-to-tail collision, and prepares the Adaptive Brake Assist for the most effective braking as soon as the driver hits the pedal.

The Attention Assist to recognise and alert a drowsy is also standard, along Adaptive Brake Assist Hold and, on manual Hill-Start Assist. This the brakes for maximum stopping in a possible emergency, adds to by holding a stationary car without the having to keep a foot on the pedal and prevents the car from backwards when setting off on gradients. Seven airbags, a driver’s knee airbag, and an Bonnet to provide additional protection are also fitted to Mercedes-Benz A-Class as standard.

features include Lane-Keeping and Blind Spot Assist, Limit Assist, Active Assist with Parktronic, Plus autonomous acceleration and to maintain a gap to the car ahead, the Mercedes-Benz Light system and the anticipatory occupant protection feature.

The new is optionally available with Online in-car internet and in 2013 it will be offered seamless integration of the Apple in conjunction with a revolutionary new interface design. Highlights advanced navigation software Garmin, with internet-based traffic information, online searches and 3-D map display.

COMAND provides internet access via a mobile phone, plus Mercedes-Benz services on the move. include weather information, and a special destination search via as well as the option of downloading a previously configured on a PC using Maps.

Mercedes-Benz has taken a different approach to the design of the new Where the previous two models essentially pragmatic — packaging the space of a large into a car with the footprint of a runabout — the new A-Class rewarding elements of dynamism and to elevate it above its compact five-door hatchback rivals.

progressive and emotive, it brings the look and feel of the latest design idiom to the compact car

The key dimensions are in themselves enough to just how much the A-Class has At 4,292 mm long, 1,780 mm and 1,433 mm tall, it is 409 mm longer, 16 mm and almost 180 mm lower than the it replaces.

Its radical form language was seen in the Concept A-Class at the Auto Show of 2011. highly acclaimed design has now transferred to the production model a huge challenge in a car of compact which had to match its rakish and appearance with a usable and five-seater interior.

Design at always begins with an competition among all the company’s The winning entry for the exterior of the A-Class came from Mark Fetherston, a graduate of University’s School of Transport who has worked at Mercedes-Benz since Fetherston has excellent design at Mercedes-Benz — he also the exterior of the SLS AMG gullwing supercar .

For the sculpted shape of the A-Class, he was by the patterns of sand dunes and landscapes — and even the lines of the Concorde — and was to take advantage of the encouragement to the design team by the Mercedes-Benz to be more progressive.

The sides of the new are characterised by sharply defined and tautly drawn convex and surfaces, which seem to change as the light catches The pronounced front end meets in a V-shape, with the Mercedes-Benz mounted in a two-louvre grille in chrome, silver, black or colour, depending on model.

The headlamp units are a key element of the design. The light modules been arranged to deliver a for the daylight running lamps and indicators, creating an instantly visual signature for the new A-Class. headlamps and LED daytime running are fitted to the A-Class Engineered by

The new A-Class has a class-leading drag figure of Cd 0.27. Nowhere is more apparent than in the and smooth arc of the roof, which in a spoiler that neatly the aerials and lends structure to the assembly.

Along the flanks, a beltline in either black or enhances the car’s pronounced profile, while another rises from the mid-point of the wheel arches to create shoulder muscles at the rear, the new Mercedes-Benz A-Class a coupé-like Between these two crisp are sensuously moulded sculptured

Dynamic sills add an athletic touch, particularly pronounced in the AMG Sport, which rides 15 mm than other models, and the Engineered by AMG with its AMG sports

The interplay of convex and concave and taut edges is repeated at the The tail lights — LED in the A-Class Engineered by AMG models continue the line of the muscular back towards the rear. horizontal orientation emphasises the width of the new model.

The tail-light are also pointers to the superior of the new A-Class: not only are they a feature in themselves, but their shaped break-away edges been designed to improve from the rear of the car.

The of the new A-Class was also inspired by two cars. The starting point was the Aesthetics No 2 sculpture revealed at the Detroit Auto Show. was then incorporated into the A-Class, which was created at the Advance Styling Studio in the Italian city of Como in for the Shanghai Auto Show in of the same year.

If the dash vents and instruments were by the world of aviation then the areas, space, quality and to detail have been to give the spacious feel of a far car.

The objective was to complement the look of the exterior while the Mercedes-Benz A-Class a high-quality and feel unique in its segment the design and the choice of materials, and textures.

The sweep of the dash the aircraft wing-inspired theme of recent new models from It incorporates five circular air with electro-plated outer on SE versions and above. Airflow these vents is controlled by nozzles reminiscent of jet engines. In the Engineered by AMG these vents a red insert matching the car’s lower centre grille. The process gives the nozzles a metal finish with a effect, and has been extended to all elements.

The instrumentation and control appear in the upper part of the while a broad lower contains the switchgear and control The production process used for the section allows a wide of soft-touch surfaces to further the quality and attention to detail the cabin.

The instrument cluster is up of two large round dials, with a smaller dial set The dial faces are either or silver with a chequered design, depending on model. the dial needles are red or white, to the trim level.

To the right of the panel is a free-standing 5.8-inch colour display screen a black piano lacquer-look panel and a flush-fitting silver This is linked to the Audio 20 system or the option Audio 20 with Media interface.

The new has been configured so that an iPhone® can be fully integrated the operating and display system via the Kit Plus special app.

For all its looks and compact dimensions, the is a full five-seater hatchback, but the accommodation has cunningly designed to like two individual seats. All from SE have sports with integrated head and sports pedals with studs.

A sports three-spoke steering wheel with trim, perforated in the grip is fitted to SE and Sport versions of the new A-Class, while AMG Sport and by AMG versions have a flat-bottomed steering wheel trimmed in leather.

The rear seat are split 2/3:1/3 and the two sections can be individually to expand the standard luggage are to a maximum of 1,157 The luggage area allows more than a metre to fit between the wheel housings.

In place of the assembly of the previous two generations, is now an advanced steel monocoque that brings about reductions in the height of the car and the seating which, in turn, lowers the of gravity. The outcome is sharper, agile, nimbler handling uncompromised passenger accommodation.

The body construction of the previous two of A-Class, which placed the partly in front of and partly a twin-floor passenger cell, has replaced by a sophisticated steel in the latest model. This has not brought about a significant in the car’s overall height, has been reduced by 160 mm, and seating which are 174 mm lower, but it has lowered the of gravity by 24 mm — an ideal point for a car engineered to deliver dynamic and agile handling.

There is a new and floor, an integral support as a deformation element, a length of 435 mm which to dissipate crash and load distribution over planes. Altogether, three planes allow impact to be absorbed in a controlled manner.

The frame is the attachment point for the axle and steering assembly as as the torque support for the transversely engine and gearbox. It is made up of steel plates and a hydroformed and is connected by two aluminium struts to the radiator mount.

The new has all-independent suspension with different levels of tuning to the ideal balance between and sportiness according to the model Suspension engineers made use of the driving simulators at the Mercedes-Benz centre in Sindelfingen, compiling a profile of the car’s dynamic as part of the development process a single prototype was built.

All suspension arrangements rely on a MacPherson strut system at the and a new four-link rear axle for the new Mercedes-Benz family of compact cars. This, combined the lower centre of gravity of the Mercedes-Benz A-Class, provides a platform for excellent dynamic

The four-link rear axle is so that forces are absorbed by control arms and one trailing arm per This means that and lateral influences on the suspension are virtually independent of each The wheel carriers and spring are made of aluminium to reduce weight. The goal was to achieve lateral agility with straight-line stability and the minimum of on the rear axle.

All three configurations deliver exemplary of comfort with precise, responses, low degrees of roll and low pitch. The A-Class has been set up mild understeer at higher of lateral acceleration so that the can control changes in direction low steering input but high precision.

Standard comfort suspension is to A 180, SE and Sport models. AMG versions have the Dynamic Package (optional on Sport), lowers the ride height by 15 mm and firmer springs and dampers AMG multi-spoke 18-inch alloy Direct-Steer is also part of the Handling Package, adding an element of agility and precision. by AMG models feature modified AMG suspension.

The latest ESP® Stability Programme includes Vectoring Brake, which to control any tendency towards in fast cornering by applying brake pressure to the outer wheel. It has been designed to gently so that skilled and drivers can extract maximum out of the car without ever reaching a critical situation.

The new A-Class redesigned electro-mechanical steering, to give drivers maximum by delivering fast, accurate while saving fuel by power assistance from the only when the car is turning. A circle of just 11 metres to the practicality, especially in urban conditions, of the A-Class.

The electric which provides servo is mounted directly on the steering The steering permits various functions in conjunction with the control unit. For example, it can for the effect of crosswinds and cambered counter the torque-steer effect in some front-wheel-drive cars, the car straight when braking on where the levels of grip from left to right, and should the car nudge towards

Engines and Transmissions

A dynamic new engine, an ultra-economical new turbodiesel and a turbodiesel make their in the new A-Class. The new petrol engine is a development of the 1.6-litre unit seen in the new B-Class, and perfectly the dynamic design and agile of the new A-Class. It develops 211 hp and 350 Nm of torque, the A-Class to 62 mph in 6.6 seconds and on to a top speed of 149

It powers the A 250 BlueEFFICIENCY AMG Sport and the A 250 Engineered by AMG, driving the Mercedes-Benz 7G-DCT seven-speed automatic transmission, which is as standard to both models.

The new diesel engine is a 1.5-litre that develops 109 hp and 260 Nm of torque, but of significance is that it allows the new to attain a combined fuel figure of 74.3 mpg with CO2 as low as 98 g/km. It is available in SE, Sport and AMG versions.

This frugal and diesel powerplant is joined by the new 2,143 cc turbodiesel engine powers the A 220 CDI BlueEFFICIENCY AMG Sport. dynamic unit develops 170 hp at rpm and a muscular 350 Nm of torque available 1,400-3,400 rpm, good for an 8.2 sprint to 62 mph and a 137 mph top speed.

Only with the 7G-DCT dual transmission, this lightweight returns 64.2 mpg on the combined and posts a CO2 emissions figure of 115 g/km. These excellent illustrate just how advanced new engine is — compared the previous generation A 200 CDI, the new A 220 CDI is 30 hp and 50 Nm more powerful, yet is 11.9 mpg economical and 34 g/km cleaner on CO2

These three new advanced join four further that made their in the new B-Class.

The familiar 1.6-litre 122 hp engine is available in standard, SE and versions of the A 180 BlueEFFICIENCY and a 156 hp version of the engine is offered in the A 200 BlueEFFICIENCY and AMG Sport. All except the standard A 180 are available with the sophisticated transmission as an alternative to the standard manual.

The highly economical diesel unit develops 109 hp and 250 Nm of in the A 180 CDI BlueEFFICIENCY SE, Sport and AMG Sport — available with the transmission. A 136 hp version of the same also powers the A 200 CDI BlueEFFICIENCY and AMG Sport. This most diesel engine derivative is with manual or 7G-DCT

The petrol engines

The all-aluminium M 270 direct-injection engine makes its in the new A-Class. This 1,991 cc develops 211 hp at 5,500 rpm and 350 Nm of torque 1,200-4,000 rpm, and is the perfect for the engaging design and dynamic of the new Mercedes-Benz A-Class.

All three M 270 are 16-valve four-cylinder units twin overhead camshafts. are extremely versatile engines, are already being phased larger Mercedes-Benz models to lower fuel consumption, and production costs. Their is exceptional — they can be both transversely (M 270) or (M 274), combined with rear or 4MATIC all-wheel and paired with manual, torque converter or 7G-DCT clutch transmissions.

They technology first introduced in with the ultra-modern BlueDIRECT V6 and V8 for the Mercedes-Benz S-Class. The combustion is based on third-generation Mercedes-Benz with highly precise, piezo-injection technology. Mercedes-Benz is a in this field — in Mercedes-Benz was the first car manufacturer to direct-injection with spray-guided into series production.

developed piezo-injectors allow up to injections per power stroke. In the phase this enables emissions to be reduced by more 90 per cent. The overall result is all emission figures, including already surpass Euro 6 standards not due to be enforced until

Piezo-injectors have numerous in petrol engines compared conventional multi-hole solenoid The fuel vaporises up to four as fast, the jet of fuel penetrates deeply into the combustion and the injectors are able to deliver quantities of fuel with precision. This prevents from being deposited on the chamber walls, resulting in reduced particulate emissions.

An charge is applied to the piezo-ceramic which changes their in microseconds, and with a precision of a few thousandths of a millimetre. The central of a piezo-electric injector is the piezo-stack, directly controls the metering With a response time of 0.1 milliseconds, the injection of fuel can be and precisely adjusted to the current and engine speed, reducing fuel consumption and combustion

The third-generation direct-injection system features rapid multi-spark (MSI). Following the first and a brief combustion period, the is recharged rapidly and there is a spark. The MSI system enables up to sparks within one millisecond. MSI can both the timing of the sparks and the period to suit the current point. This provides for the best possible combustion, further reduces fuel Fuel savings of up to 4 per cent are possible by the use of piezo-electric injection combined with MSI.

has developed an innovation known as for its 1.6-litre engine. CAMTRONIC is a management system which intake cut-off and intake lift adjustment, and is a first in a direct-injection petrol engine. It throttling losses under load, lowering fuel by three to four per cent. In driving, which typically has a proportion of partial load the potential saving is even with fuel savings of up to 10 per It was developed completely in-house by the Technology Centre in Stuttgart and the engine plant in Berlin.

The specific outputs of the small-capacity M 270 are the result of turbo-charging, which intake air into the combustion at a pressure of up to 1.9 bar, with the vanes rotating at up to 230,000

The turbo-charger has been designed to high torque even at low speeds. It is integrated into a developed manifold turbo-charger positioned in front of the engine for the possible cooling. Separate ducting from the cylinders to the and a high exhaust temperature of up to degrees Celsius make use of the exhaust gas energy, producing a output and outstanding responsiveness.

By using a combination of direct-injection and adjustment of the intake and exhaust the engines are also able to the advantages of so-called scavenging. involves a partial overlap of the times of the intake and exhaust causing some of the cold air to flush the hot exhaust gas from the into the exhaust manifold, considerably improves charging.

At low speeds the turbo-charger also much more rapidly, reducing turbo-lag when off. The direct-injection system that the fresh gas is not yet mixed fuel when it enters the as would be the case in engines manifold injection. No unburned is therefore flushed into the manifold.

As a result, the 1.6-litre in the A-Class delivers its 200 Nm maximum at 1,250 rpm, maintaining twist action through to rpm. The 2.0-litre version even better results its maximum torque of 350 Nm is available 1,250 rpm through to 4,000 which means that it the field for four-cylinder engines.

A new management system has also developed for these powerplants. In state, a switchable water with flow-optimised ball ensures that no coolant through the engine, allowing the chambers to heat up quickly. The is electronically controlled and the coolant are adjusted according to driving and ambient conditions.

The variable oil pump operates with two stages. At low engine speeds and the pump runs at a pressure of 2.0 bar and the nozzles for piston cooling are off. The high-pressure stage is at higher loads and engine As a result, the lubrication and cooling of the requires significantly lower energy than with an pump.

The coolant ducting in the head is also new. The mantle is a two-piece construction to flow. This leads to increases in flow speeds and dissipation at certain points, by a reduction in pressure losses the coolant circuit. This has it possible to reduce the power of the water pump despite an in engine output.

As it warms up, the of coolant is regulated by a triple-phase management system so that it reaches normal operating Initially the coolant remains at in the engine. It then circulates in the circuit, but bypasses the radiator. a temperature of 105 Celsius has been the radiator is included in the circuit.

To absolute smoothness at all times, are two Lanchester balancer shafts in the of the 2.0-litre engine block to the secondary inertia forces in four-cylinder in-line engines. is the first car manufacturer to use anti-friction to balance these masses.

is achieved via cylinder roller with axial forces the gearing taken up by a ball This arrangement not only smoothness, but also helps to fuel consumption by reducing Because of its more favourable rod configuration, the 1.6-litre engine not need Lanchester shafts.

is also minimised by a reduction in through the oil and water pumps, pistons, piston rings and walls, plus the new thermal system and chain drive.

The and transmission are mounted at four — by an engine mounting, a mounting and two pendulum supports. are specially configured for the needs of the engines to minimise noise. The damping integrated into the mounting also contributes to driving comfort.

The turbodiesel

Two new turbodiesel engines make debut in the new A-Class. Features sixth generation common-rail with a rail pressure of bar, low-pressure Exhaust Gas and variable geometry turbo-charging.

The 1.5 engine in manual versions of the A 180 CDI generates 109 hp and a healthy 260 Nm available 1,750 rpm to 2,500 rpm, and CO2 figures which start at 98 g/km, making the new A-Class the most environmentally friendly diesels in its sector.

This and clean diesel powerplant is by the range-topping new 2,143 cc turbodiesel that powers the A 220 CDI BlueEFFICIENCY. dynamic unit develops 170 hp at rpm and a muscular 350 Nm of torque available 1,400-3,400 rpm, good for an 8.2 sprint to 62 mph and a 137 mph top speed.

Only with the 7G-DCT dual transmission, this engine a weight-optimised crankshaft with bearing covers bolted below and four counterweights, it to tip the scales at around six kilograms than a longitudinally installed OM 651 of the same displacement. The single-stage has larger dimensions than in the other less-powerful variants.

It a 64.2 mpg on the combined cycle and a CO2 emissions figure of just 115 These excellent figures just how advanced this new is — compared with the generation A 200 CDI, the new A 220 CDI BlueEFFICIENCY is 30 hp and 50 Nm powerful, yet is 11.9 mpg more and 34 g/km cleaner.

These two new join the 1.8-litre turbodiesel developed by Mercedes-Benz for the new B-Class and now in the A-Class. The A 180 CDI BlueEFFICIENCY in tandem the 7G-DCT double-clutch automatic employs a 109 hp version of the 1.8-litre engine, while the A 200 CDI BlueEFFICIENCY a 136 hp version of the engine alongside a manual gearbox or the 7G-DCT.

The new engine, which has been the in-house designation OM 607, is for its low weight. Components specific to include the engine mountings of the M 270 engine as well as a bespoke flywheel. The starter, the alternator and the compressor also come the Mercedes-Benz modular system, and are by a belt with six grooves. all Mercedes-Benz engines, the OM 607 was required to an extensive test programme bench and endurance runs.

engineers put the engine through a schedule to improve NVH (noise, and harshness) and driveability. Coordination also went into the ECO function which is standard on all of the A-Class. This feature, to Mercedes-Benz, operates at temperatures to minus 10 degrees Celsius so it can make a greater contribution to economy.

All three diesel in the Mercedes-Benz A-Class are extremely thanks to state-of-the-art injection and turbo-charging. The 1.8-litre units are of the OM 651 fourth-generation 2.2-litre four-cylinder premiered in 2008. Downsizing for the has been achieved by shortening the stroke from 99 to 83 mm. They an aluminium cylinder head and a block.

Compared with the version used in the rear-wheel-drive and E-Class models, they a modified belt drive and air and a new turbo-charger mounting to suit installation. Cylinder spacing of 94 mm and camshaft drive make particularly compact.

Third-generation technology, with the rail increased to 1,800 bar and a maximum pressure of 200 bar, allows versions of the engine to attain high specific outputs. is aided by a two-piece water in the cylinder head to provide cooling.

A number of engineering further enhance fuel The oil injector nozzles and the water become active only necessary, reducing energy on the engine, while the oil pump oil flow in a controlled manner. The two balancer shafts which the engines their exemplary under all loads run in low-friction bearings rather than plain bearings. The long rods also help friction and therefore improve economy.

Since its world premiere in the OM 651 has been setting standards in of performance, torque, economy, and smooth running. It is in more use than any other Mercedes-Benz engine and serves as a model of and power from the new A-Class up to the S-Class.

Thanks to BlueDIRECT and highly precise piezo-injection, the easily surpass the anticipated 6 emission standards coming force from 2015. For engines the regulations are particularly in relation to particulate limits, but has been able to better requirements without recourse to exhaust after-treatment.

ECO start/stop

All of the new A-Class are fitted with and extremely efficient ECO start/stop which ensures that no is used and no emissions are created the car is stationary in traffic. The system stops the engine when the car is at and swiftly restarts it the moment the wishes to pull away.

It not require any intervention by the driver. the six-speed manual gearbox, the switches off as soon as the driver the brakes, shifts the transmission into neutral and releases the The engine restarts when the presses the clutch.

With the dual-clutch automatic transmission, the ECO function deactivates the engine the driver presses the brake and the car comes to rest. The engine automatically when the driver’s is removed from the brake or the accelerator pedal is pressed.

A of defaults ensure it functions under full driver and when certain safety have been met. it will work only the car is stationary. In manual versions, the must be applied, the transmission be in neutral and the clutch pedal be released. With the 7G-DCT the shift lever must be in or Neutral.

In both cases, must be no steering wheel the doors and bonnet must be and the driver’s seat belt be fastened. The driver’s foot be on the brake pedal or the Hold must be active. The engine restart if it detects a vehicle-related such as extensive use of the air conditioning

The ECO start/stop system employs a which monitors the angle of the and the position of each cylinder. The determines which cylinder is in the position for ignition when to ensure smooth and instantaneous Mercedes-Benz direct-start technology the system operates spontaneously and little noise. Fuel is directly and ignited during the compression stroke, allowing the to fire up with little from the starter.

Advanced management ensures the ECO start/stop operates only when the and cabin have both the correct temperature. The driver can the system off if required. To handle the of the ECO start/stop system, the starter has been modified so that it can with eight times the number of starting procedures so even in continuous urban it will last the car’s A second battery supports the electrical system.

7G-DCT dual-clutch automatic

The 7G-DCT dual-clutch automatic which made its debut in the new B-Class, is available in the majority of new models, and standard on both the A 250 BlueEFFICIENCY and the A 220 CDI BlueEFFICIENCY diesel-powered

It delivers the comfort and convenience of a automatic system with the economy of a manual transmission. It drivers to exercise full control via paddles mounted the steering wheel, with changes taking place far than even the most driver can execute with a transmission. There are three programmes — Economy, and Manual.

In ECONOMY, gearshifts are automatic, but take place at the possible engine revolutions to the most fuel-efficient driving In SPORT, the gear changes are fully automatic, but are completed rapidly to minimise torque and maintain momentum.

In both the driver can intervene to make a shift at any time using the wheel paddles. The transmission to automatic mode if no manual changes are made within the 12 seconds, or after a longer when driving downhill or on roads. MANUAL mode full control to the driver, and the take place even than in SPORT.

The two wet multi-disc running in an oil bath are ideally to engines with high outputs like the direct-injection units of the new Mercedes-Benz A-Class. The are activated and the gears shifted without any interruption in power The seven ratios of the 7G-DCT been chosen to permit acceleration from standstill quiet, economical cruising.

The 7G-DCT is more compact and than comparable transmissions other manufacturers, and is operated by a lever and shift paddles into the steering wheel, a for a compact family car. One of the operates the odd-numbered gears and the works the even-numbered gears so the next gear is always ready to come into instantaneously and smoothly as needed, accelerating or braking.

Cruise and the Speedtronic variable speed are included with the 7G-DCT transmission in Sport, AMG Sport and by AMG models, along with the Hold function. All the driver to do is push the brake pedal more firmly than and the car will remain held the need to keep pressing the down. The Hold function restrains the car momentarily when off on steep gradients to prevent it backwards.

Six-speed manual

The standard transmission in the new A-Class is a new manual gearbox developed in with the 7G-DCT. They a large number of components and are in the same Hedelfingen plant.

The manual transmission is, like the compact and light, and designed for quick and positive shifting. cast-aluminium shift forks are on anti-friction bearings on the shift to reduce the effort needed for changing. A wide spread of ensures the new A-Class is particularly when setting off and yet is able to quietly and economically at motorway

It is this approach which has led to develop the radar-based Collision Assist, fitted as standard to the new range. Mercedes-Benz tries and foremost to ensure its cars are to avoid accidents — is why the A-Class is also fitted as with Attention Assist, Brake Assist, anti-lock (ABS) with Brake (BAS), ESP® with Skid Control (ASR).

But it ensures they are among the cars on the road should the happen, so there are seven including a driver’s knee and an Active Bonnet to offer further protection. The Pre-Safe® crash protection is optionally

The first of defence: the body shell

The line of defence is provided by the of the A-Class body itself. The new has sailed through Mercedes-Benz’ programme of crash tests. includes not only some 30 impacts required for safety and international type approval, but nine crash tests, as the roof-drop test or the pole test, developed by Mercedes-Benz.

The of the new Mercedes-Benz A-Class to satisfy far beyond statutory standards is by an internal offset front test. Despite the high speed, the A-Class passenger remained intact.

The ability of the shell to offer such a standard of passive safety is to the materials used — the of high-strength and ultra-high-strength steels is 67 per — and its structural design. At the end there is an impact absorption of 435 mm to soak up crash loads, are dissipated over several

A total of three longitudinal — straight front members, an upper plane of aluminium box sections attached to the end, and a third plane at the in front of the subframe — impact energy to be reduced in a controlled manner.

It of several steel plates, in ultra-high-strength steel, and a hydroformed The subframe is connected via two aluminium leading forward to the aluminium mount. In a frontal impact, can be discharged into the subframe via this third load to ensure the best possible dissipation.

A plastic crash at the rear of the front wheel helps to ensure that the do not slide under the front in a high-impact crash, so that it is possible to open the doors.

steels are used in the upper of the B-pillar to minimise intrusion and to the passenger cell in case of impact. The lower area of the is softer so that it dissipates better. The insides of the B-pillar what are referred to as ‘vampire’s to prevent cracking that ensue if the seat belt presses against the inner of the B-pillar.

The new A-Class features measures designed to help the risk of injury to pedestrians in the of a collision. The deformation space the bonnet and the components beneath it has maximised by relocating items as control units or fluid in the engine compartment.

For the A-Class, its sleek, low-slung body, is also an active bonnet. In the of a pedestrian impact, sophisticated combined with intelligent trigger actuators around the hinges. These raise the by 65 millimetres. The additional space creates between the bonnet and areas in the engine compartment that a pedestrian’s head is to comparatively low acceleration forces on

Intelligent restraint systems

The protects occupants with airbags as standard, including a knee bag. There are driver and front-passenger airbags, thorax-pelvis bags incorporated in the seats and window bags extend over both of seats to the A-pillar.

The driver and airbags operate in two stages, to the expected severity of the impact. The gas first fills the driver’s with 60 per cent gas and the front airbag with 70 per cent If a more severe impact is the second stage of the gas generator activate and the airbags will be at a higher pressure. Rear bags are optionally available.

The steering column yields by up to 100 mm the driver exerts pressure on the The head restraints for the driver and passenger are new developments to minimise the of whiplash injury. The key to effective prevention is to have the best distance between the head and the head of the person in the seat. The incorporates a button on the left-hand to unlock the head restraint and the distance. The button does not to be pressed to reduce the distance.

protection: planning ahead

The new meets the rear-seat protection of the Japanese and Chinese NCAP This takes into factors such as the ease of use of the and Mercedes-Benz safety experts that Euro NCAP soon extend its rating to include rear-seat safety.

The A-Class is already prepared for with features such as belt tensioners and belt limiters for the outer rear A torsion bar in the roller mechanism when the load on it exceeds a level. In this way the belt is limited and with it the load on the occupant. The A-Class has ISOFIX seat mounting points on outer rear seats. seats can additionally be fixed via anchorage points with top

Pre-Safe®: anticipating accidents

the Mercedes-Benz anticipatory occupant system which premiered in the of 2002, is available in the A-Class for the time as part of the on-going to cascade advanced safety throughout the range. It uses the between detection of a potential and a possible collision to initiate protection measures, thus the loads exerted on occupants if a occurs by up to 40 per cent.

On receiving the the emergency centre establishes contact with the vehicle within seconds in the language the driver has pre-set in COMAND Other than any mobile communication charges, no costs are by the driver and no additional phone is required to use this service.

range of driver assistance

The innovative radar-based Collision Assist heads a host of driver assistance systems to be in the new Mercedes-Benz A-Class. Collision Assist gives a visual and warning to a possibly distracted of the risk of a nose-to-tail accident. At the time it prepares Brake for full emergency braking of the force exerted on the pedal by the

Unlike other assistance in compact cars, Collision Assist does not merely minor damage in low-speed Instead, it protects against collisions at speeds above 19 Field tests carried out by in Europe, North America, and South Africa over a distance of more than million miles since confirm that the most rear-end collisions are at speeds 19 mph.

Mercedes-Benz expects the effect of Collision Prevention will be similar to that followed the introduction of ESP® as Tests involving 110 drivers in the simulator saw the accident rate from 44 to 11 per cent in three scenarios thanks to the combination of warning and adaptive braking Mercedes-Benz safety experts Collision Prevention Assist can around 20 per cent of all nose-to-tail and reduce the severity of them in a 25 per cent of cases.

Collision Assist can recognise when the is too close to the vehicle ahead at between 19 and 155 mph and warn the driver and acoustically. It can also recognise the gap is decreasing, detect stationary ahead at up to 45 mph and adapt the activation for the warning and adaptive Brake to given driving situations. It the precise braking force to avoid an accident.
