Mercedes A-Class Coupe, 2009

Mercedes A-Class Coupe, 2009

 
 
With more than 500,000 units produced within three and a half years, the Mercedes-Benz A-Class is among the bestsellers in the Mercedes-Benz passenger car range. Now the latest generation of this compact car is showing itself to be more youthful, attractive and environmentally compatible than ever before. This is ensured by a completely revised design, high-grade appointments and new technical developments which further improve safety, comfort and economy. A convenient ECO start-stop function which reduces urban petrol consumption of these BlueEFFICIENCY vehicles by up to nine percent is now available for the high-volume models A 150 and A 170, for example. For the three-door A 160 CDI Mercedes-Benz has developed an additional BlueEFFICIENCY package which lowers the fuel consumption of the Coupé by more than eight percent, to 4.5 litres per 100 kilometres. Independent experts have acknowledged these great advances in the environmental field with an internationally valid environmental certificate, which the Mercedes-Benz A-Class is the world's first compact car to achieve.

In spring 2008 Mercedes-Benz is presenting the five-door Saloon and the three-door Coupé in completely upgraded versions. Viewed from the front, this compact Mercedes-Benz now appears more youthful and self-confident than before. The sweeping lines of the newly designed headlamps harmoniously combine the front end and flanks, which literally appear to be cast from a single mould. The redesigned front bumper reinforces this impression; its lower air intake is now much larger, emphasising the width of the body. The radiator grille is also in a new design which underlines the progressive aura of the Mercedes-Benz A-Class.

Lines: ELEGANCE and AVANTGARDE with an even more pronounced styling emphasis
Design features at the front end provide more distinctions between the design and equipment lines of the Mercedes-Benz A-Class. While the louvres in the radiator grille of the basic version are painted in dark-grey, they are respectively in metallic atlas grey and high-sheen iridium silver in the ELEGANCE and AVANTGARDE lines, and are also visually upgraded by additional chrome strips. Discreet chrome trim strips further reinforce this impression. In the AVANTGARDE line, the front bumper also has a distinctive design which emphasises the arrow-shape of the front end and suggests greater agility.

When viewed from the side the different lines in the Mercedes-Benz A-Class are distinguished by wheel designs. While the basic model is equipped with 15-inch wheels and seven-spoke wheel embellishers as standard, ELEGANCE and AVANTGARDE are fitted with individually designed 16-inch light-alloy wheels. The new, larger exterior mirror housings and door handles are now painted in the vehicle colour for all model variants. The previous side rubbing strips have been replaced by discreet chrome trim strips, which provide additional visual highlights in the ELEGANCE and AVANTGARDE models.

Interior: upgraded with larger stowage compartments and new fabrics
Mercedes designers paid particular attention to enhanced value when redesigning the interior, choosing new, high-grade upholstery fabrics and door linings. In the ELEGANCE and AVANTGARDE lines the seats are upholstered in an attractive combination of ARTICO man-made leather and fabric, which is available in three colours. In addition new decorative trim of smoke-grey, diagonally brushed aluminium enhances the interior of the AVANTGARDE line, while the dignified aura of the ELEGANCE models is heightened by wood trim. All variants of the Mercedes-Benz A-Class share a larger stowage compartment in the centre console and a newly designed cupholder between the front seats.

Fuel economy: the A 160 CDI BlueEFFICIENCY consumes 4.5 litres
With fuel consumption figures between 4.9 and 8.1 litres per 100 kilometres, the new-generation A-Class is a model of fuel economy. Thanks to detailed improvements, the fuel consumption of the state-of-the-art direct-injection diesel engines has been reduced by more than eight percent or 0.5 litres per 100 kilometres compared to the preceding series. From autumn 2008 Mercedes-Benz will introduce a standard BlueEFFICIENCY package for the three-door A 160 CDI with a manual transmission, with further improvements in engine efficiency, aerodynamics, rolling resistance, energy management and weight. The sum of these measures achieves a fuel saving of 0.4 litres, which means that the A 160 CDI BlueEFFICIENCY has an NEDC consumption of just 4.5 litres per 100 kilometres. As a result the CO2 emissions of the 60 kW/82 hp Coupé are 119 grams per kilometre.

The BlueEFFICIENCY package also includes an aerodynamically optimised radiator grille. This has a closed-off interior face to reduce the airflow to the engine, though the CDI engine is still cooled effectively at all times. The suspension has also been lowered by ten millimetres to reduce the drag coefficient even further.

Start-stop function: the engine switches off automatically when idling
In the case of the petrol engines, Mercedes engineers have achieved NEDC fuel savings of up to 0.4 litres per 100 kilometres with a newly developed ECO start-stop function. From autumn 2008 this system will be available for the high-volume models A 150 and A 170 on request. It automatically switches off the engine when the driver shifts the manual transmission to neutral at a low speed while applying the brakes. If the conditions for engine switch-off are met, the driver is informed by a special display in the instrument cluster.
Economy: nine percent lower fuel consumption in city traffic

Ecology: the Mercedes-Benz A-Class is the first compact car with an environmental certificate
Practical trials such as this are of immense importance to Mercedes-Benz when it comes to evaluating new technologies. The environmental compatibility of vehicles is not only assessed on the basis of standardised emissions and fuel consumption measurement, but also taking into account the entire vehicle lifecycle - from production and many years of operation to eventual recycling and disposal. An analysis of more than 40,000 individual processes provides an overall picture and enables the development work to be objectively assessed.

Safety: flashing brake lights warn following traffic
The adaptive brake light introduces technology from the luxury class into the compact segment, which therefore benefits from a further accident prevention system as a standard feature. Under emergency braking from a speed exceeding 50 km/h, the brake lights flash rapidly to warn following traffic, enabling drivers to respond quicker and prevent a collision.

Flashing brake lights are the result of extensive practical research covering the braking behaviour of drivers. Mercedes engineers found that the braking responses of drivers are on average 0.2 seconds faster in emergency braking situations if a flashing red warning is given in place of conventional brake lights. The stopping distance can be reduced by around 4.40 metres from a speed of 80 km/h, and even by around 5.50 metres from a speed of 100 km/h. If the A-Class is brought to a rapid stop from a speed exceeding 70 km/h, the hazard warning system is switched on in addition to the flashing brake lights.

Parking assist: ultrasound and electric steering for easier parking
When finding and reversing into a parking space, drivers of the Mercedes-Benz A-Class will in future be aided by an active parking assist feature which is available on request for all model variants. Using side-mounted ultrasonic sensors, this system identifies suitable parking spaces on both sides of the road in passing, then informs the driver by means of a display. The sensors are active up to a speed of 35 km/h, and monitor the area to the left and right of the Mercedes-Benz A-Class. They measure the length and depth of possible parking spaces, indicating that the search is in progress with a " P " in the instrument cluster.

Mercedes A-Class, 2009

Mercedes A-Class, 2009




 
The Mercedes-Benz A-Class has made a name for itself as a trendsetter and innovative leader in its class. Outstanding safety, great day-to-day flexibility and reliability have always been among the strengths of the Mercedes-Benz A-Class, which has so far captured the enthusiasm of about 1.7 million customers with its distinctive and versatile vehicle concept.

Lines: ELEGANCE and AVANTGARDE with an even more pronounced styling emphasis

Design features at the front end provide more distinctions between the design and equipment lines of the Mercedes-Benz A-Class. While the louvres in the radiator grille of the basic version are painted in dark-grey, they are respectively in metallic atlas grey and high-sheen iridium silver in the ELEGANCE and AVANTGARDE lines, and are also visually upgraded by additional chrome strips.

All variants of the Mercedes-Benz A-Class share a larger stowage compartment in the centre console and a newly designed cupholder between the front seats.

The luxury seat package with seat cushion angle adjustment and lumbar support, seat height adjustment for the driver's seat, a front armrest and a parcel net in the front passenger footwell is standard equipment for ELEGANCE and AVANTGARDE models.

Fuel economy: the A 160 CDI BlueEFFICIENCY consumes 4.5 litres

With fuel consumption figures between 4.9 and 8.1 litres per 100 kilometres, the new-generation A-Class is a model of fuel economy. Thanks to detailed improvements, the fuel consumption of the state-of-the-art direct-injection diesel engines has been reduced by more than eight percent or 0.5 litres per 100 kilometres compared to the preceding series.

From autumn 2008 this system will be available for the high-volume models A 150 and A 170 on request. It automatically switches off the engine when the driver shifts the manual transmission to neutral at a low speed while applying the brakes. If the conditions for engine switch-off are met, the driver is informed by a special display in the instrument cluster.

Within fractions of a second, and almost noiselessly, the engine is restarted as soon as the clutch is operated or the brake released. This rapid and comfortable engine start is a major advantage of the ECO start-stop function versus other systems of this kind. To this end Mercedes-Benz uses a starter generator which is linked to the crankshaft via the drive belt. As a result the engine starts much more rapidly and quietly than with the conventional starter. During a journey the starter generator feeds electrical power to the onboard network of the Mercedes-Benz A-Class.

Economy: nine percent lower fuel consumption in city traffic

With the ECO start-stop function the NEDC fuel consumption is reduced by a further 6.5 percent or so. The A 150 BlueEFFICIENCY (70 kW/95 hp) absolves a measured test journey with a fuel consumption of 5.8 litres per 100 kilometres, which corresponds to 139 grams of carbon dioxide per kilometre.

Mercedes C63 AMG Estate F1 Medical Car, 2009

Mercedes C63 AMG Estate F1 Medical Car, 2009


 


The Mercedes-Benz SL63 AMG F1 Safety Car, another permanent feature of each Formula 1 race is the Mercedes-Benz C63 AMG Estate F1 Medical Car. At the start of every Grand Prix, the high-speed AMG estate car follows the Formula 1 field on the first lap. This is because the first lap represents a critical phase of the race in which the Formula 1 vehicles are especially tightly bunched. In the event of an accident during the race, the Medical Car is the first vehicle on the scene and is able to guarantee the fastest possible emergency treatment.

The Mercedes-Benz C63 AMG Estate has excellent credentials for such a challenging task, where literally every second counts: the high-performance estate vehicle is powered by the AMG 6.3-litre V8 engine, which delivers 336 kW/457 hp and 600 Newtonmetres of torque. The AMG sport exhaust system boasts larger pipe diameters and new rear silencers, this resulting in a considerably more distinctive sound that comes out of the two chrome-plated dual tailpipes. In order to guarantee greater reliability, the cooling of coolant, engine oil, transmission oil and power steering has been optimized, this being visible also from the new AMG front apron with its considerably larger cooling-air openings. The power from the engine is transmitted via the AMG SPEEDSHIFT 7G-TRONIC PLUS, which blips the throttle when changing down for even greater smoothness. Perfect traction is guaranteed by the combination of 3-stage ESP® and differential lock with 35 percent locking effect.

Coil-over suspension and AMG high-performance braking system

An adjustable coil-over suspension and 19-inch AMG light-alloy wheels, measuring 8 and 9 inches wide and fitted with tyres of sizes 235/35 (front) and 255/30 (rear), respectively, help to ensure perfect contact with the road. The powerful AMG high-performance braking system, with its internally ventilated and perforated composite brake discs on the front axle, guarantees extremely short stopping distances. The Official F1 Medical Car differs from the standard-production Mercedes-Benz C63 AMG Estate with its new AMG front apron with larger cooling-air openings as well as special brake cooling. The active cooling of the rear-axle differential is integrated into the diffuser insert at the rear. Like the Safety Car, the Medical Car, too, draws attention to its special role on the track through its F1 logos, roof bar and strobe-like LED flashlights at front and rear. Enhanced visibility in darkness or bad weather is ensured by the LED-illuminated number plate with Medical Car lettering on the boot lid tailgate.

The Mercedes-Benz C63 AMG Estate F1 Medical Car is driven by racing driver Alan van de Merwe (South Africa). His co-driver is Dr. Gary Hartstein (Belgium), who is the official FIA Grand Prix Chief Medical Officer. Both of them are accommodated in AMG sports bucket seats with 4-point seatbelts, as are the two medical assistants in the rear. Two monitors in the centre console help the crew to supervise the action on the racetrack, while an on-board two-way radio system is responsible for communication with the race management. The functional feel of the interior is marked by black leather appointments and aluminium trim parts. The 365-millimetre AMG performance steering wheel with its flat underside on the steering wheel rim and AMG aluminium shift paddles guarantees perfect control over the vehicle. With its unrivalled volume of 485 litres, the luggage compartment offers ample space for the full complement of emergency equipment, including defibrillator and respirator.

Mercedes B-Class, 2009

Mercedes B-Class, 2009

 
 

The restyled front end injects the Mercedes-Benz B-Class with more poise and assurance than before. This is primarily down to the radiator grille with its three chromed cross fins painted in metallic grey and the Mercedes star integrated into its centre. However, the more imposing appearance of the Mercedes-Benz B-Class also stems from the new-look bumper - whose design emphasises the large air intake at the bottom - as well as the modified bonnet. This new design idiom makes the front look broad and, as a consequence, especially powerful, symbolising the sporty attributes of the Mercedes-Benz B-Class even more clearly than before. The design at the sides seems more harmonious and elegant than before, because the exterior mirror housings, door handles and skirt panels are now painted to match the body colour on all model variants.

The rear styling picks up on the dynamic flow of lines at the front and along the sides. A direct visual link is created by the tail light assemblies, whose upper edges merge seamlessly with the character line along the vehicle's sides. The tail lights sport a new high-brilliance look and draw the gaze to the large tailgate, which now comes with en ergonomically enhanced chrome handle strip.

Interior: high-grade appointments with new upholsteries and trims

High-class appeal, attention to detail and a sense of ample spaciousness - these qualities have always been intrinsic to the Mercedes-Benz B-Class. The winning blend of forms, colours and materials teams up with the interior's roominess, the pleasant feel of all its surface materials and the expansive window areas to produce a most inviting ambience. This is helped by the high seating position - which, incidentally, improves the driver's all-round view, too - while the relatively high waistline fosters a sense of security without making the occupants feel confined.

The Mercedes design team has further upgraded the interior with a new upholstery fabric, plus a new fabric pattern for the seat cushions. If the Mercedes-Benz B-Class is ordered with the sports package, the side seat bolsters are trimmed in ARTICO man-made leather and the centre panels in fabric. The interior door linings likewise feature a new fabric trim.

The centre console continues to be bordered by trim strips on both sides, but they are now made from diagonally brushed aluminium in a smoke grey finish. The same, integrated trim is found again in the vicinity of the gearshift and in the door panelling, giving the interior an added sense of refinement.

Diesel engines: fuel consumption reduced by seven percent

the Mercedes-Benz B-Class continues to be available with a choice of six engines - two direct-injection diesel units (80 kW/109 hp and 103 kW/140 hp) delivering up to 300 newton metres of torque, as well as four petrol engines with a peak power output of up to 142 kW/193 hp and a maximum torque of 280 newton metres. The four-cylinder power units have undergone a series of detailed improvements in order to further reduce fuel consumption.

For the diesel models, this means that the combined NEDC fuel consumption of the B 180 CDI and B 200 CDI has dropped by as much as seven percent - depending on tyre size - to 5.2 - 5.4 and 5.4 - 5.6 litres per 100 kilometres, respectively. The two turbodiesel models, which are particularly smooth-running thanks to a balancer shaft, will therefore be an even less frequent sight at the filling station from now on; the B 180 CDI can clock up over 1000 kilometres on a single tank of fuel (54 litres).

Petrol models: new fuel-saving ECO start/stop function
Depending on the model and engine output, the four petrol variants of the B-Class return fuel consumption figures of between 6.6 and 8.1 litres per 100 kilometres on the NEDC driving cycle. From autumn 2008, motoring is set to become even more economical with the arrival of the B 150 and B 170 BlueEFFICIENCY models featuring the ECO start/stop function. This newly developed function automatically switches the engine off when the driver shifts to neutral at low speed whilst depressing the brake pedal. If the criteria for stopping the engine are fulfilled, a special display appears in the instrument cluster to inform the driver.

Natural-gas drive: a clean and economical alternative
A further new addition to the Mercedes-Benz B-Class range bears the initials "NGT" on the right-hand side of its tailgate. They stand for "Natural Gas Technology" and identify a model variant which is as economical as it is environmentally compatible, courtesy of its bi-fuel drive: the B 170 NGT BlueEFFICIENCY is able to run on both natural gas and premium grade petrol while delivering an identical maximum output of 85 kW/116 hp.

In addition to the petrol tank, there are five natural gas reservoirs whose total capacity of 16 kilograms equates to a range of over 300 kilometres. With overall NEDC consumption figures of 7.3 litres of premium petrol and 4.9 kilograms of natural gas per 100 kilometres, the new B 170 NGT BlueEFFICIENCY is therefore able to attain a total range in excess of 1000 kilometres. The driver determines which power source the engine is run on at the touch of a button using the multifunction steering wheel; an electronic control unit carries out the switch instantaneously without any jolts - even while on the move.

The four-cylinder engine has been modified by Mercedes-Benz to include additional gas injectors on the underside of the intake manifold. A close-coupled pressure governor with an electromagnetic shut-off valve regulates the supply of natural gas and keeps the pressure within the system constant.

The installation of the gas reservoirs, which are located in the rear and underneath the front passenger footwell, reduces the boot capacity of the B-Class by 128 to 422 litres (as per the VDA measurement method), but there is still sufficient space for carrying a family's luggage.

The lower carbon dioxide emissions and cheaper fuel costs make natural gas an attractive alternative to petrol and diesel, both ecologically and economically speaking. On the NEDC cycle, the CO2 emissions are 17 percent lower than in the petrol-powered B 170 at 135 grams per kilometre. If the 4.9 kilograms (7.5 m³) of natural gas consumed per 100 kilometres by the new B 170 NGT BlueEFFICIENCY is converted into the equivalent quantity of petrol energy, the fuel cost per kilometre is around 50 percent less than when running on petrol.

Environmental Certificate: first ever lifecycle assessment for NGT drive too
Mercedes engineers have, for the first time, compiled an eco balance sheet for the natural-gas drive. It forms one element of the Environmental Certificate awarded to the Mercedes-Benz B-Class by Germany's TÜV Technical Inspection Authority. Mercedes-Benz is the only automotive brand in the world to have been granted this certificate, which is based on the stringent international standard ISO 14062 "Design For Environment". It is a confirmation of the Stuttgart-based brand's commitment to all aspects of environmental protection. In contrast to just the standardised measurement of exhaust emissions and fuel consumption on the roller dynamometer, Mercedes engineers analyse the environmental compatibility of vehicles over their entire lifecycle - starting with their manufacture, continuing with their many years of use and finishing with their end-of-life disposal.

The results of this integrated analysis over a total distance travelled of 150,000 kilometres highlight, for example, a number of clear advantages for the natural-gas drive. The overall CO2 emissions are some 20 percent below the figure for the comparable petrol-engined model. Nitrogen oxide emissions are eleven percent lower, while the experts have calculated a 54 percent difference in carbon monoxide emissions over the entire lifecycle in favour of the natural-gas drive. The greater ecological cost of the manufacturing process for the new B 170 NGT is therefore balanced out after a distance of 17,300 kilometres.

Occupant protection: extensive safety features enhanced yet further

When it comes to safety, the Mercedes-Benz B-Class sets an example for all other models of these dimensions to follow: in the European NCAP test programme, the Sports Tourer was awarded the highest rating of five stars.

The comprehensive safety specification, comprising two-stage front airbags, belt tensioners for the front and outer rear seats, belt force limiters plus active head restraints in the front, ISOFIX child seat attachment points and head/thorax sidebags, has now been complemented by the addition of crash-responsive emergency lighting in the passenger compartment. Following an accident of a predetermined severity, the lighting comes on automatically to allow the occupants to get their bearings more easily in the dark and expedite the work of the rescue services.

Active safety: flashing brake lights as a warning to other motorists

Accident prevention is the overriding priority of the Mercedes safety concept - a concept that is geared towards motoring reality. To help them bring critical situations under control safely and with ease, drivers of the Mercedes-Benz B-Class can count on highly effective, standard-fit technology in the form of systems such as ABS, Brake Assist and ESP®. Mercedes engineers have however gone that little bit further by seeking to devise a way of offering other motorists added safety too. The result is a simple but highly effective method of avoiding rear-end collisions: flashing brake lights. This safety technology is included as standard on the 2008 model year B-Class.

During testing, Mercedes engineers were able to ascertain that the braking reaction time of motorists is quickened by an average of 0.2 seconds if they see a flashing red warning signal instead of conventional brake lights in an emergency braking situation. This shortens the stopping distance by around 4.40 metres if they are travelling at a speed of 80 km/h, and by a whole 5.50 metres or so when braking from 100 km/h. Brake lights flashing at a high frequency therefore prove to be an effective means of alerting drivers behind to the risk of a rear-end collision.

The flashing brake lights are triggered automatically if the driver initiates emergency braking when travelling at a speed of 50 km/h or more. And if the B-Class is braked to a stop from a speed of over 70 km/h, the hazard warning lights will come on too.

Assistance systems: automatic parking with ultrasound and electric steering

The Electronic Stability Program has been expanded to include a new, standard function: the automatic hill-start assist. This prevents the Mercedes-Benz B-Class from rolling backwards as the driver switches from the brake to the accelerator pedal when starting off uphill. In such situations, the ESP® briefly maintains the brake pressure to make pulling away easy.

Reverse parking will pose less of a challenge for motorists in future. The new active parking assist (optional) searches for an appropriate spot at the side of the road as the Mercedes-Benz B-Class drives by, than takes care of all the steering manoeuvres as the driver reverses into it. How it works: at speeds below 35 km/h, ultrasonic sensors at the sides of the car scan the zones to the immediate left and right of the Mercedes-Benz B-Class, and measure the length and depth of any potential parking spaces. Once a suitable spot has been found, the system flashes up a message in the display to inform the driver. When the driver engages reverse, confirms the display and presses the accelerator, the active parking assist takes over the steering and automatically manoeuvres the B-Class into the space. All the driver has to do is operate the accelerator and brake; the PARKTRONIC system's ultrasonic sensors provide further assistance by indicating how much room there is in front of and behind the Mercedes-Benz B-Class.
