2012 Mercedes-Benz ML

Has just been unveiled and already the majority of the audience expressed their feelings "of love" to the next generation of the German model. ML 2012 has received a huge portion of criticism on the design. However, the truth is that many spy shots announced that the new ML in no case will not be a shock in terms of aesthetics. Some compared it with the new Cayenne, both at the taillights, and the front grille, accusing a certain lack of originality. Others crucified it, saying that the SUV from Stuttgart not is not imposing respect anymore by the new look implemented by the Germans. In other words, the ML seems to be a real catastrophe in terms of style. However, there have been some who have manifested a certain attraction for German creation.

Mercedes Benz ML-2012 is 24 mm longer, 16 mm wider, height is lowered by 19 mm, a figure far too small for fans of smaller SUVs.

Even if the aesthetic level, the car was buried in a giant avalanche of negative comments, the new ML has managed to pleasantly surprise in terms of motorizations, which are more elevated. 350Bluetec version features a 3.0-liter V6 diesel engine with a stud of 258 horsepower (190 kW) and 619 Nm (457 lb-ft) of torque, values ​​with which the sprint from 0-100 km/h (62 mph) is achieved in 7.5 seconds.

In gasoline engines, the new ML features a 3.5-liter V6. Speedometer needle climbs up to 235 km/h (146 mph).

All engine variants come in standard with four-wheel drive system, transmission 7G-Tronic seven-speed Plus adaptive dampers. Self-adaptive Airmatic suspension remains an option, as the Active Curve and dynamic stability for the body rolling.

The options list also includes Night View Assist with the role of pedestrians recognition, Speed ​​Limit Assist for assistance to maintain lane, DISTRONIC Plus, and other delights.

There are currently no known information about the AMG version and the price of the new ML.

2012 Mercedes-Benz SLK Gullwing Hybrid


Mercedes-Benz clearly wants to revive in style those beautiful rising doors that made history in the 50s. That's why a little brother for the yet-to-be-unveiled SLC supercar is on the way.

The future mini supercar could use the underpinnings of the 3rd generation of the SLK-Klasse, which should hit the streets in 2011. The rumoured SLK Gullwing will feature a hybrid powertrain:a 3,5 litres V6 internal combustion engine(probably, the current one, which boasts a 305 BHP output/360 Nm max. torque and an electronically-limited max. speed of 250 km/h) and an electric unit coupled to Li-Ion batteries.

Specifically, those state-of-the-art technology batteries are the reason for planning such a dramatic SLK version. Mercedes-Benz intends to install them in the side sills, so there would be no room for the conventional doors. 

The 2012 Mercedes-Benz SLK Gullwing will try, as best as it can, to protect the environment:regenerative brakes and START/STOP function to be fitted, a 150 g CO2/km gas emission, an average 5,9 l/100 km fuel consumption, 193 km of all-electric autonomy. However, the car won't forget its main objective as a sports car, so it will ensure a 0-100 km/h sprint in approximately 5 seconds.

2011 MERCEDES-BENZ SLS AMG GT3


2011 MERCEDES-BENZ SLS AMG GT3


Automobile fascination paired with spectacular race car design - that is the new Mercedes-Benz SLS AMG GT3. The racing version of the SLS AMG has been conceived as a customer sport vehicle for participation in race series based on FIA GT3 regulations. Meticulous lightweight construction and optimized chassis, brakes and aerodynamics deliver uncompromising dynamics. The extra special Mercedes-Benz SLS AMG will make its race track debut in 2011.

The clean design and breathtaking form of the Mercedes-Benz SLS AMG have been effectively accentuated by targeted modifications to the bodyshell. The new components, made largely from lightweight carbon fiber offer a clear indication of extraordinary race track performance and extensive aerodynamic development work.

From the front, the GT3 race car boasts a new front skirt with enlarged air intakes. The wide opening beneath the characteristic radiator grille bearing the large Mercedes star and the wing-shaped horizontal fins supplies air to the engine oil cooler and brake discs. The same function is served by the two intakes below the vertical bi-xenon headlamps. Downforce on the front axle is provided courtesy of four externally mounted side flics, as well as a carbon front splitter; it runs directly into the smooth underbody panel, which connects to the rear diffuser.

The hood features a central opening for the extraction of heat from the engine, while side openings in the front fenders facilitate air flow through the wheel arches. Weight optimization measures include the application of extremely lightweight polycarbonate for the side and rear windows and, if desired, for the front windshield as well.

The fenders have been widened front and rear to accommodate the large racing tires. With a breadth of 78.3 inches, the GT3 bodyshell is a good 2 inches wider than the series production Mercedes-Benz SLS AMG. The new sills feature openings for cooling the rear brakes, with the smooth underbody visible along the underside of the sills. The B-pillar houses the standardized fuel tank adapter for the rapid refueling system. The 31.7 gallon fuel tank is located centrally behind the driver.

Wide rear carbon spoiler
The rear view of the Mercedes-Benz SLS AMG GT3 is dominated by its imposing width. Above the rear hatch sits a wide carbon fiber spoiler; it is extensively adjustable and facilitates perfect setup to suit individual race track characteristics. The new rear skirt accommodates two openings for extracting air from the rear wheel arches. A further visual highlight is the rear carbon fiber diffuser; it rises smoothly from the rear axle area as a continuation of the smooth underbody, its form adding to the downforce. The overall aerodynamic concept of the Mercedes-Benz SLS AMG GT3 was analyzed and defined through extensive wind tunnel and race track testing.

The black exhaust end pipes deliver a fascinating and, at the same time, characteristic AMG eight-cylinder sound. The regulation rain lamp is integrated into the rear hatch - it must be switched on by the driver in poor weather conditions.

Close to series production AMG 6.3 liter V8 engine
As defined in the FIA GT3 regulations, the AMG 6.3 liter V8 engine is virtually identical to that of the series production vehicle. Thanks to its low weight, the acceleration figures for the GT3 - 3.7 seconds for the sprint from 0 to 60 mph - are considerably below the already excellent figures for the series production vehicle. Depending on gear ratio, the top speed is more than 186 mph.

The AMG 6.3 liter V8 engine uses dry sump lubrication in the racing vehicle, too. The application of a suction and pressure pump, as well as an external oil tank means that the conventional oil sump can be omitted. This technology ensures reliable lubrication of the engine under high lateral acceleration, of the kind usually experienced on the race track.

Dry sump lubrication also facilitates a low mounting position for the V8 power unit - one of the key technological highlights of the Mercedes-Benz SLS AMG. The solution - installing the eight-cylinder as low as possible and as a front mid engine behind the front axle, combined with a transaxle transmission layout - results in excellent weight distribution.

Six-speed racing transmission with sequential shift
In contrast to the series production vehicle, the Mercedes-Benz SLS AMG GT3 is equipped with a six-speed racing transmission with sequential shift. Thanks to its compact construction, the race-tested transmission offers considerable packaging benefits - ultimately, the GT3 version has less ground clearance than the series production vehicle. The driver shifts gear using two shift paddles on the steering wheel. The transmission is mounted directly on the rear axle and connected to the V8 engine via a torque tube, which has a very high degree of flexural and torsional stiffness. This delivers considerable benefits when it comes to dynamics, as this sophisticated solution enables the entire driveline to be laid out with significantly less play. Alongside the traction control, a multi-plate locking differential integrated into the transmission delivers outstanding acceleration characteristics. Inside the torque tube, a drive shaft rotates at engine speed. As in the series production model, and in the Mercedes-Benz C-Class DTM touring car, the shaft is made from carbon fiber.

With its long wheelbase, low center of gravity and wide track, the SLS AMG vehicle concept was predestined for the race track - its strengths include precise turn-in characteristics, first-class agility, low inertia under sudden changes of direction and a high cornering limit.

It required only minimal modification for perfect race track performance. The lightweight aluminum chassis with double wishbone suspension at all four corners has modified kinematics to take into account the lower vehicle height. The array of adjustability options facilitates optimal modification to suit individual race track characteristics and varying weather conditions. As well as the ability to vary the spring and damper setup, there is also the freedom to adjust track and camber, vehicle height and the stabilizers on the front and rear axles.

Like the series production SLS AMG, the GT3 version is also equipped with rack and pinion steering with speed-dependent power assistance. The more direct input ratio facilitates even greater handling agility on the race track.

AMG race braking system using composite technology
Shortest stopping distances, highest stability and optimal control are guaranteed by the AMG race braking system. All four corners feature brake discs in motorsport-tested composite technology. Gray cast iron axial and radial floating discs are fixed to an aluminum hat via stainless steel composite elements. This sophisticated technology enables perfect heat dissipation and thus reliable stability. The Mercedes-Benz SLS AMG GT3 is also equipped with precisely calculated cooling channels - openings in the front skirt and ahead of the rear wheels direct cool airflow over the brake discs. All four brake discs are ventilated, slotted and drilled. Six-pot fixed calipers on the front axle and four-pot fixed calipers at the rear, finished in anthracite with the AMG logo in white, provide plenty of brake pad surface. An anti-lock brake system with special race track settings is fitted as standard. Due to space restrictions, the AMG high-performance ceramic composite brake system, available as an option on the series production vehicle, is not compatible with the 18-inch wheels prescribed by FIA regulations.

The AMG center-locking alloy wheels - 12x18 inches front and 13x18 inches rear - are fitted with racing tires in formats 11.3 x 26.9 inches (front) and 12.4 x 27.9 inches (rear). Depending on the application, the tires are available as profile-free slicks, intermediates or wet weather tires. The classic multi-spoke design aids ventilation of the braking system. Fast pit stops and wheels changes are ensured by the pneumatic lift system integrated into the underbody. Four pneumatic rams raise the GT3 race car by around 7.5 inches, enabling the pit crew to change the racing tires in double quick time.

Interior with racing bucket seat and race steering wheel
On opening the gullwing doors, the Mercedes-Benz SLS AMG GT3 displays a functional interior with a distinctly race car feel. The driver sits in a racing bucket seat fitted with a six-point harness and the HANS system (Head and Neck Support) that fixes the helmet in place in the event of an accident, thus minimizing the risk of injury. Additional safety comes courtesy of the steel roll cage, which also serves to further stiffen the aluminum spaceframe.

A steering wheel with a diameter of 13 inches facilitates perfect vehicle control. Because it is open at the top, the driver always has a perfect view of the central display, which provides all relevant information such as road speed, engine speed, operating temperatures, lap times and gear selection. The steering wheel is fitted with a quick-release mechanism that makes entering and exiting the vehicle considerably easier. The switches on the steering wheel hub enable the driver to activate additional functions such as the pit radio, headlamp flasher and the drink supply. Further operating elements are mounted on the center console and include the start/stop function for the AMG V8 engine, the traction control, reverse gear and - just in case - the integrated fire extinguisher. The control for adjusting brake balance is located on the torque tube tunnel.

The close relationship between the GT3 and its series production sibling is demonstrated by the instrument cluster, with its powerfully taut wing profile providing visual breadth. Integrated into the dash are the highly distinctive air vents galvanized in "Silver Shadow" and with adjustable cross-shaped nozzles - their form evocative of a jet engine.

Deliveries of customer vehicles to start early 2011
The new Mercedes SLS AMG GT3 has been developed in accordance with FIA GT3 regulations and is entitled to participate in all GT3 race series - including the popular 24-hour races in Spa-Francorchamps, Belgium, and on the Nürburgring in Germany. Interested customers can order the vehicle starting in autumn 2010, with delivery scheduled prior to the start of the 2011 racing season. Homologation will be completed in March 2011.

2011 MERCEDES BENZ SLS AMG

 

2011 MERCEDES BENZ SLS AMG


Design: purist, distinctive and passionate
The distinctive styling of the new Mercedes-Benz SLS AMG enthrals with its passionate sportiness and reinterprets the breathtaking lines of the Mercedes-Benz 300 SL - one of the outstanding design icons of the Mercedes-Benz brand. With its purist design the new SLS AMG reflects the philosophy of contemporary sports car engineering: the bonnet which measures just under two metres, the low greenhouse positioned well to the rear and the short rear-end with an extendable aerofoil are just as powerful a reminder of the superlative dynamism as the long wheelbase, the wide track and the large wheels. The short overhangs feed through into the proportions, just as does the design of the super sports car with its low-slung front-mid engine set well back and dual-clutch transmission in transaxle configuration. An undoubted styling highlight comes courtesy of the gullwing doors which lend the Mercedes-Benz SLS AMG its incomparable charisma - making a unique statement in this vehicle segment.

The gullwing doors are not alone in rekindling memories of the Mercedes-Benz 300 SL; the hallmark wide radiator grille with the large Mercedes star and the wing-shaped cross fins are a throwback to the front-end of the sports car legend. The three-dimensional, sculptured front-end with its low-set, swept-back front apron set well into the sides lends the 'Gullwing' its powerful stance on the road. Six large cooling air intakes and the vertically arranged headlamps set well to the outside with their alluring inner ambience provide a dominant aura: the central bi-xenon low-beam headlamp with its metallic wing section is framed at the top by two LED indicators and the LED daytime driving lights at the bottom.

Influences from aircraft construction
Allusions to aircraft construction come courtesy of the prominent Mercedes star, whose tubular section is reminiscent of the air intake on a jet engine when viewed from the side, as well as the long bonnet: as the eye is drawn forward, so the observer becomes more aware of the curve. The design of the four fins with their Silver Shadow finish that adorn the two air outlet grilles on the end of the bonnet create the same visual impression. These aircraft-style lines also visually accelerate the air that flows past - and make the Mercedes-Benz SLS AMG appear extremely dynamic even while stationary.

The fins on the bonnet are taken up on the vehicle flanks: the connoisseur also discovers here a hallmark styling feature of the 300 SL. The "6.3" lettering placed between the fins provides a clear reference to the high-displacement naturally aspirated V8 engine. The side air outlet feeds through into a stylistically prominent feature line, which together with the convex flanks and the exhilarating surface treatment, combines aesthetics with power. The compact passenger compartment proves as alluring as it is unmistakable. With its high beltline, low side windows and steeply angled windscreen it comes across as a kind of visor. The forward angled B-pillar with its stylish flowing sweep to the rear window exudes pure dynamism.

Side view dominated by muscle and shoulder
Seen from the side, the eye is drawn to the prominent vehicle shoulder of the Mercedes-Benz SLS AMG, which stretches like a taut muscle from the front to the rear. Distinctive 19-inch (front) and 20-inch (rear) light-alloy wheels fill the wheel arches, which stand out prominently from the sidewall. Three different wheel variants all provide a glimpse of the large high-performance composite brakes. Seen from above, a prominent, uninterrupted line runs from the muscle to the rear. This styling feature is also picked up on the bonnet where the eye follows a distinctive contour which flows over the roof between the gullwing doors, right through to the third brake light.

Rear view that emphasises width
The rear view of the Mercedes-Benz SLS AMG also exudes dynamism and power: the gently sloping boot lid emphasises a sense of width, an impression reinforced by the prominent vehicle shoulder and the sleek tail lights: fitted with LED technology, the horizontally structured lighting units provide a scintillating view. Wing-shaped LED lighting elements ensure a distinctive, enthralling night design. The Formula-1-style LED fog lamp/reversing light is set down low in the centre. Similarly inspired by motor racing are the black diffuser insert and the two chromed tailpipes of the sports exhaust system. The strikingly tapered rear apron provides an unimpeded view of the wide rear wheels, lending the 'Gullwing' its self-assured stance on the road. The spoiler integrated in the boot lid is automatically deployed from a speed of 120 km/h to ensure optimum stability at high speeds.

New colours: "AMG ALU-BEAM silver" and two matt finishes
The colour charts for the Mercedes-Benz SLS AMG include nine exclusive paint finishes. The highlight comes in the shape of the unique "AMG ALU-BEAM silver" paintwork: the new, unique process makes the paint shine like liquid metal. The paint covers the body panels like a metallic skin, emphasises the scintillating design lines of the 'Gullwing' more strongly than any previous paint job and makes them even livelier by means of targeted light reflections. This effect is made possible thanks to tiny pigments measuring between 30 and 50 nanometres.

The two matt finishes "designo magno allanite grey" and "AMG magno sylvanite grey" are just as eye-catching: with their matt silk surface they reinforce the sporty character of the two-seater through specific contouring of the crease lines.

Interior with allusions to aircraft construction and motor sports practicality
You only need to open the gullwing doors on the Mercedes-Benz SLS AMG and ease into the sports seats to experience a whole new level of interior. The Mercedes-Benz designers took their inspiration from aircraft construction when styling the interior - immediately bringing an aircraft cockpit to mind. The characteristic styling feature is the dashboard, whose powerful and dramatic wing shape makes for an impression of width. Strikingly integrated into the dashboard are the galvanised air vents with their adjustable, cruciform nozzles and Silver Shadow finish - their shape reminiscent of a jet's engines. The instrument cluster with its LED upshift indicator and two white backlit dial instruments add another decidedly sporty touch with their metallic Silver Shadow finish. The silver dials have red needles and a 360 km/h speedometer scale. As a central feature of the cockpit, the COMAND APSmultimedia system with its 7-inch screen is integrated between the two centre air vents.

The elongated centre console in matt metal similarly picks up on the design theme of the aircraft cockpit. It is home to the AMG DRIVE UNIT, which is inclined towards the Mercedes-Benz SLS AMG driver and allows them to choose their very own vehicle setup. The E-SELECT shift lever, whose styling recalls the thrust control of a jet, controls the AMG SPEEDSHIFT DCT 7-speed sports transmission. All the controls are made out of solid metal, with a high-sheen Silver Shadow surface.

The concave inner panels of the gullwing doors, the high beltline and the powerful side sill panels round off the cockpit-like impression, while imparting a feeling of sports car-like ergonomics. Fine materials such as nappa leather, solid metal and (optional) genuine carbon-fibre facings underline the pronounced "custom-built" nature of the Mercedes-Benz SLS AMG interior, and show enormous attention to detail. Five different designo leather colours are available to meet individual preferences: black, classic red, sand, porcelain and light brown.

Wide-opening gullwing doors for easy entry
Despite the low sitting position of just 369 millimetres in typical sports car fashion, the wide-opening gullwing doors make it easy to get in and out of the vehicle. At the design stage great attention was paid to the widest possible opening angle - it is a full 70 degrees. Equally importantly, the distance between the open doors and the road surface is a generous 1.50 metres, while the entry aperture between the open doors and the upper edge of the door sills measures no less than 1.08 metres. The entrance height, i.e. the distance between the road surface and the upper edge of the door sills is a very low 45 centimetres. As another important criterion for dignified access and egress, two gas-pressure struts positioned next to the door hinges require only very little pressure when opening and closing the doors - even at very low ambient temperatures.

The gullwing doors require less opening space than conventional coupé doors, and can be fully opened in a normal garage. The door is opened from inside by a handle finished in Silver Shadow. The grip section of the armrest moulded into the interior door panel ensures problem-free door closing. The operating buttons for the power windows, central locking system and exterior mirror adjustment are also located in the interior door panels for easy access. The feeling of comfortable spaciousness is in large measure due to the generous shoulder-room of 1483 millimetres and elbow room of no less than 1606 millimetres. In conjunction with the generous maximum headroom of 990 millimetres and effective legroom for the driver of 1058 millimetres, the result is a low but extremely relaxed seating position. At the same time the intentionally steep angle of the windscreen ensures good all-round visibility for the passengers.

Sports seats with magnesium backrests
The sports seat backrests are made from magnesium, a high-tech material that combines light weight with high strength. This leads to significant advantages where weight distribution and a low centre of gravity are concerned. The sports seats feature so-called two-zone seat cushions. Prominent side bolsters with a harder foam filling provide optimal lateral support, while the inner areas of the seat cushion and backrest are softer for a high level of comfort on long journeys. In conjunction with the Memory package (optional), the fore-and-aft position, seat height, backrest angle, squab angle and steering column are electrically adjustable; three individual settings can also be stored.

Four-way lumbar supports reliably protect the lower spine, while adjustable side bolsters in the backrests effectively improve lateral support on fast bends. Three-stage seat heating and seat occupancy/child seat recognition in the passenger seat are also standard equipment.

The sports seats with integrated head restraints and sporty transverse fluting are upholstered in designo leather - and two-tone seats are also available in classic red, sand and porcelain. If light brown is chosen as an interior colour, the sports seats are upholstered in natural leather with particularly high-quality woven leather on the centre seat panels. Depending on the colour combination, fluorescent or black piping provides another sporty touch.

The Performance leather steering wheel in a three-spoke design has a 365-millimetre rim with a flattened lower section, shift paddles and a metal insert, underlining the authentic custom-built look and ensuring the best possible vehicle control.

A host of stowage space for hallmark Mercedes day-to-day suitability
The interior of the Mercedes-Benz SLS AMG also impresses with the practical stowage space that makes for the day-to-day suitability typical of a Mercedes. The 3.7-litre glove compartment with a spectacles section is integrated into the dashboard on the passenger side. To the right of the E-SELECT shift lever there is a small stowage tray with a 12 V socket, or an ashtray with cigar lighter. The armrest behind the centre console not only serves to operate the COMAND Controller: at the touch of a button, the armrest can be moved in two stages to reveal a stowage compartment underneath. This has two cupholders and the telephone cradle (optional), and a holder for the ignition key in the rear section. Other items can be stowed on the rear wall between the seats and in the parcel net in the passenger footwell. Two fixed clothes hooks are attached to the seat backrests, while those in the roof liner fold down and are silicon-insulated.

The button to unlock the boot lid is located underneath the light switch. Alternatively the boot can be opened using the ignition key. The luggage compartment can hold up to 176 litres. A made-to-measure luggage set is available as an option, which enables the boot space to be used to full advantage.

Aluminium spaceframe for lightweight design and outstanding strength
The Mercedes-Benz SLS AMG is also breaking the mould when it comes to the body concept: for the first time, Mercedes-Benz and AMG are presenting a car with an aluminium chassis and body. Compared with the traditional steel design, this results in a significant weight saving, clearly illustrated in the DIN kerb weight of 1620 kilograms.

The newly developed bodyshell comprises an aluminium spaceframe. This exclusive design combines intelligent lightweight design with outstanding strength - thus delivering superlative driving dynamics. Lightweight aluminium sections connect the force nodes to a sturdy structure. The large, low-set cross-sections of these aluminium sections ensure high resistance torque, thus providing the required direct transfer of drive, braking and suspension forces. The structure prevents unwanted flexibility; the vehicle responds rigidly, almost without twisting and directly.

45 percent of the intelligent, weight-optimised aluminium spaceframe is made out of aluminium sections, 31 percent out of aluminium sheet, 20 percent out of aluminium cast and 4 percent out of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars. The bodyshell weighs 241 kilograms - an absolute benchmark in the super sports car segment when compared with the peak output of 420 kW/571 hp.

Low centre of gravity and transverse reinforcing struts for superb dynamism
The entire vehicle concept has been designed to achieve a centre of gravity that is as low as possible. This applies both to the low connection of the powertrain and axles as well as to the arrangement of the stiffness-relevant bodyshell structure, which has been kept as low as possible. Examples include the rigid flexural and torque connections between the front and rear section and the safety passenger cell, which have been realised consistently using force paths that are as low as possible. This results not only in a low centre of gravity but also a harmonious and, thus, efficient force path in the vehicle structure.

Another prominent feature of the lightweight construction design is the transverse reinforcing struts at the front and rear axle that are integrated into the bodyshell structure. The sections connect the side members precisely where the highest forces act upon the bodyshell under dynamic cornering. The advantages of this sophisticated solution include unrivalled transverse rigidity and the absence of heavy secondary stiffening or supports.

Passive safety of the very highest calibre
Naturally, the aluminium spaceframe meets all the requirements in terms of passive safety and the hallmark Mercedes-Benz body quality that applies to any car sporting the Mercedes star. The best possible passive safety for the occupants is ensured by the standard-fit three-point seat belts, belt tensioners, belt force limiters and eight airbags: two adaptive airbags and a kneebag each are available for the driver and passenger. Two sidebags integrated into the seats and two separate windowbags that deploy from the door waistline are also available.

Fine-tuned AMG 6.3-litre V8 engine developing 420 kW/571 hp
A powerful eight-cylinder engine manufactured by Mercedes-AMG forms the heart of the new SLS. The fine-tuned 6.3-litre V8 engine develops 420 kW/571 hp at 6800 rpm, turning the

Mercedes-Benz SLS AMG into one of the most powerful sports cars in its segment. A power-to-weight ratio of 2.84 kg/hp comes courtesy of the low vehicle weight. The naturally aspirated engine delivers maximum torque of 650 Nm at 4750 rpm. The 'Gullwing' accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed electronically limited to 317 km/h (all figures are provisional). Bearing the internal designation M 159, the V8 high-revving engine with its displacement of 6208 cubic centimetres has been thoroughly reengineered compared with the M 156 entry-level engine and boasts all the hallmarks of powerful racing engines.

The principal measures in increasing output include the all-new intake system, the reworked valve train and camshafts, the use of flow-optimised tubular steel headers and the de-throttling of the exhaust system. This results in much better cylinder charging, which feeds through into an increase in output of almost nine percent. The eight-cylinder engine responds swiftly to movements of the accelerator pedal, demonstrating much more pronounced high-revving flexibility across the entire rev range. The switch to dry sump lubrication also translates into a much lower position of the engine in the vehicle. And lowering the vehicle's centre of gravity has also paved the way for high lateral acceleration and exhilarating driving dynamics.

Perfect synthesis of lightweight design and strength
The use of high-strength components compensates for the increased engine load associated with the higher output. Forged pistons, a reinforced crankshaft bearing, optimised crankcase structure, along with improved lubrication thanks to an on-demand high-performance oil pump ensure optimum durability. Despite these higher loads, the engine weight for the M 159 has been further reduced. The forged pistons as oscillating masses play a particularly valuable role in this respect, resulting in a kerb weight of 205 kilograms and, in turn, a power-to-weight ratio of 0.36 kg/hp - an unrivalled figure compared with the competition. Sophisticated catalytic converter technology enables current and future exhaust emission standards such as EU 5, LEV 2 and ULEV to be met.

A match for demanding fuel consumption targets
Despite its uncompromisingly sporty character, the demanding fuel consumption targets have been met. The Mercedes-Benz SLS AMG consumes 13.2 litres per 100 kilometres (combined, provisional figure), earning it a place at the top of the competitor rankings. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimised twin-wire-arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimised oil supply and intelligent generator management: during the engine's overrun phases and braking, kinetic energy is used to charge the battery, rather than being wasted by simply generating heat. This recuperation assists the driver not only during braking action but also helps convert the braking energy into electrical energy. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine.

Dual-clutch transmission with transaxle configuration and torque tube
The AMG 6.3-litre V8 engine delivers its abundant power via an ultra-light carbon-fibre driveshaft at the rear axle - similar to the set-up used on the DTM C-Class racing touring car. The dual-clutch transmission is mounted at the rear (transaxle principle) and is connected to the engine housing via a torque tube. A carbon-fibre shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution are associated with the rigid link between the engine and trans-mission and, in turn, the optimum support for the forces and torque generated.

A new AMG SPEEDSHIFT DCT 7-speed sports transmission takes care of power transfer. The dual-clutch transmission boasts fast gear changes with no loss of tractive force - in as little as 100 milliseconds. The driver has a choice of four different driving modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) or "M" (Manual) along with a RACESTART function. In the Sport, Sport plus and Manual modes the automatic double-declutching function is active; all the modes can be selected conveniently via the rotary control in the AMG DRIVE UNIT. Optimum traction comes courtesy of the mechanical differential lock, which is integrated in the compact transmission casing.

Sophisticated suspension layout with double-wishbone axles
The chosen solution with a front-mid engine plus transaxle configuration ensures an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created the ideal conditions for consummate driving dynamics with precise steering, first-class agility, low inertia with spontaneous directional changes and outstanding traction. The commitment of Mercedes-Benz and AMG to building an alluring super sports car that combines consummate racetrack performance with hallmark Mercedes long-distance comfort has given rise to an ingenious suspension layout. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing, right through to Formula 1. With a double-wishbone axle, the wheel location and suspension function remain separate; the spring/damper struts are supported on the lower wishbone. The double-wishbone concept with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.

Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminium - substantially reducing the unsprung masses; this configuration also notably improves the suspension response. The long wheelbase of 2680 millimetres not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle's tendency to dive and squat. The broad track width - front 1682, rear 1653 millimetres - ensures lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tyres to retain more grip. The large caster angle of 11.5 degrees significantly increases negative wheel camber when cornering and also improves tyre grip - this also ensures outstanding stability when braking heavily while cornering.

Direct steering, differential lock and 3-stage ESP®
The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves the feedback for the driver as the road speed increases: an indispensable factor for high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The 'Gullwing' comes with 3-stage ESP® as standard, providing the driver with access to the three "ESP ON", "ESP SPORT" and "ESP OFF" modes at the push of a button. The result is even more driving pleasure without compromising active safety at all. In "ESP OFF" mode too, operating the brake pedal restores all the normal ESP® functions.

The system's traction logic of the acceleration skid control system (ASR) is active in all three ESP®modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction notably - especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road even more effectively when driving in a particularly dynamic style.

Ceramic composite brakes, innovative flow-forming wheels
The AMG high-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under enormous loads. The newly developed, optional ceramic composite brakes with larger brake discs guarantee even better brake performance. The ceramic brake discs will perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the unsprung masses has further optimised the handling of the 'Gullwing' - which pays dividends particularly when tackling fast bends on motorways.

Lightweight construction was also key when it came to the wheels: weight-optimised AMG light-alloy wheels - 9.5 x 19 inch (front) and 11.0 x 20 inch (rear) - based on the innovative flow-forming principle reduce the unsprung masses while increasing driving dynamics and suspension comfort. In addition to the standard-fit AMG 7-spoke light-alloy wheels, 5-twin-spoke wheels and 10-spoke forged wheels are available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tyres developed exclusively for the Mercedes-Benz SLS AMG ensure optimum performance. A tyre pressure monitoring system is fitted as standard to permanently monitor tyre pressure in all four wheels; individual tyres are shown on the display.

The reinterpretation of the legendary 'Gullwing' is scheduled to be launched in spring 2010. The sales price is EUR 177,310 (incl. 19% VAT).

The Mercedes-Benz SLS AMG embodies a blend of consummate automotive fascination and high tech. The super sports car delivers a compelling mix of purist styling, consistent lightweight design and superior driving dynamics. At the same time, the Mercedes-Benz SLS AMG fully lives up to all the expectations of hallmark Mercedes everyday practicality and optimum safety. In essence, the new 'Gullwing' offers the ideal synthesis of the strengths of Mercedes-Benz and AMG.

The new super sports car from Mercedes-Benz and AMG makes for an alluring proposition with its unrivalled technology package: aluminium spaceframe body with gullwing doors, AMG 6.3-litre V8 front-mid engine developing 420 kW/ 571 hp peak output, 650 Nm of torque and dry sump lubrication, seven-speed dual-clutch transmission in a transaxle configuration, sports suspension with aluminium double wishbones and a kerb weight of 1620 kilograms based on the DINstandard - this superlative combination guarantees driving dynamics of the highest order. The ideal front/rear weight distribution of 47 to 53 percent and the vehicle's low centre of gravity are testimony to the uncompromising sports car concept. The 'Gullwing' accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed of 317 km/h (electronically limited). The fuel consumption of 13.2 litres per 100 kilometres (combined) puts it at the front of the competitive field (all figures provisional).

"Mercedes-Benz is presenting an exhilarating super sports car in the guise of the Mercedes-Benz SLS AMG, which is bound to set the pulses of all car enthusiasts racing that extra bit faster. The brands Mercedes-Benz and AMG have joined forces to create the Mercedes-Benz SLS AMG - which is set to become one of the most alluring sports cars of all time", says Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.

"Our customers will experience with the Mercedes-Benz SLS AMG the expertise of Mercedes-AMG, built up over 40 years of motor racing. The unrivalled technology package delivers outstanding driving dynamics coupled with moderate fuel consumption figures - part and parcel of the modern-day AMG," says Volker Mornhinweg, Chairman of Mercedes-AMG GmbH.

"The styling of the new Mercedes-Benz SLS AMG is not only very special because of the exclusive gullwing doors. Our aspiration is to utilise this interpretation to create the classic of tomorrow and roll out the most alluring sports car of the 21st century. Our aim is also to create a new design icon, which shapes the incomparable legend of our brand, alongside Mercedes models like the CLS or the SL. At the same time, the new Mercedes-Benz SLS AMG paves the way for the design philosophy of forthcoming Mercedes-Benz sports cars", says Gorden Wagener, Head of Design at Mercedes-Benz Cars.

2010 MERCEDES BENZ Shooting Break Concept



2010 MERCEDES BENZ Shooting Break Concept


The Mercedes-Benz Shooting Break concept car represents a clear indication of the further emotional appeal of the Mercedes design idiom. In October 2004 Mercedes-Benz established a new market segment with the four-door Coupé CLS. In September 2008, the brand revealed a fresh and exciting interpretation of the emotionally-appealing Coupé-based design in the form of the FASCINATION concept car. Now making its premiere at Auto China 2010 is the Mercedes-Benz Shooting Break concept car - a further insight by Mercedes designers into the possible future development of the Coupé concept.

Wide and flat, with a long bonnet and a roof which continues through to the rear: the Mercedes-Benz Shooting Break concept car features some astonishing proportions which at the same time are clearly reminiscent of another design icon - the CLS. The design of the front is completely new, but makes use of elements which are mindful of the SLS AMG super sports car: the radiator grille, with the large star and eye-catching, bionic slats, is not integrated into the bonnet but has been designed separately in the form of a "soft nose". The grille is flanked on each side by full LED headlamps, which for the first time feature LED technology for all of the usual dynamic light functions. The side profile is given a touch of dynamism thanks to the high, exaggerated beltline sweeping towards the rear, and the dramatic character line which is supported by the powerful-looking rear wheel arches. The coupé-like side view is also emphasised with a low window design which also highlights the greenhouse with polished aluminium trim.

The interior is dominated by natural wood and leather materials. One eye-catching feature is the large full-length centre console. It highlights the four- seat layout as well as the high levels of comfort afforded by the Mercedes-Benz Shooting Break concept car. The wooden floor of the luggage compartment reflects the true interpretation of this area of the vehicle, where the dark-stained silky oak contrasts against inlaid aluminium protective loading strips.

The Mercedes-Benz Shooting Break concept car is driven by the forerunner to the forthcoming new V-engine generation from Mercedes-Benz. The V6 benefits from a 60° cylinder angle and a displacement of 3.5 litres, and is characterised by direct injection featuring a control system which enables lean-burn operation. The six-cylinder engine produces 225 kW (306 hp) with a maximum torque of 370 Nm and in line with the BlueEFFICIENCY criteria of Mercedes-Benz also sets new standards among the competition in terms of fuel consumption.

The exterior: stylish and sporty
The proportions are clearly those of a coupé: the long bonnet, narrow-look windows with frameless side windows, and dynamic roof sloping back towards the rear create a basic stance with which it looks ready for the off. It is only when taking a second look that it becomes clear that the Mercedes Shooting Break concept car actually has four doors and an estate rear. As such, this study in design reveals its philosophical links with the four-door CLS Coupé, a car which has established a new market segment since 2004 and today is already seen as a design icon which is likely to occupy a very special place in the history of the motor car. The Mercedes-Benz Shooting Break concept car may well be looked back on at some point as having played a similar role, taking ideas from the FASCINATION concept car premiered in 2008 and projecting them into the future.

"The Mercedes Shooting Break concept car is based on the great tradition of a stylish, cultivated sportiness which has always characterised the great Mercedes Coupés, and it takes this unique legacy an exciting step further," explains Professor Gorden Wagener, chief designer at Mercedes-Benz. "At the same time it points the way towards the future design idiom of Mercedes-Benz."

The vocabulary of the design idiom includes the contrasting play between lines and exaggerated areas, which combine to create an animated area of interaction. The expressive design of the front immediately catches the eye, using elements which are mindful of the SLS AMG super sports car, and with a radiator grille which for the first time has been designed as a "soft nose" and is not integrated into the bonnet. This contributes to better pedestrian protection and at the same time also helps to improve the focus on the long, sporty bonnet. The grille is dominated by the large central star, highlighting its relationship to the other Coupés of the Mercedes brand. It is supported by bionic, curved grille slats. Their curved design is reflected in the expressive look of the front apron and air intakes.

Particularly eye-catching are the full LED headlamps, which for the first time offer all of the regular dynamic light functions using LED technology. Inside they are divided into three arrow-shaped layers from top to bottom: the upper layer contains an LED indicator, beneath which is a striking LED side light offering LED low beam functions. The side light can also be seen when the dipped beam function is switched on, thereby creating a novel and separate night-time design and distinctive look. The lowest level of the headlamp houses the main beam and nightview functions. A total of 71 LEDs not only provide an unmistakable appearance, but also a significantly enhanced view of the road compared with previous systems.

The side profile of the Mercedes-Benz Shooting Break concept car is dominated by the low, frameless side windows, the coupé-like shape of which is further highlighted with the incorporation of a polished aluminium frame along the body. Thanks to the positioning of the outside mirrors on the beltline, the side line is emphasised and all-round visibility has been improved in the region of the A-pillars. The side windows are supported on a high beltline, which slopes towards the rear in a fresh interpretation of the classic "dropping line" of iconic Mercedes Coupés. An additional exciting touch has been made with the prominent, muscular hip points which forcefully support the side line. This interaction gives the impression of a sprinter, poised in the starting blocks, ready to release an explosive forward surge of energy. The roof follows through to the rear and also drops away in typical coupé fashion. Another special feature is the recessed, filigree door handles, which emerge on being touched with the aid of sensors to allow access to the interior.

The side view is rounded off with wide wrap-around tail lights featuring LED technology. As such they form a linking element to the low, steeply-angled estate car rear end with top-hinged tailgate. The shape is emphasised by the broad shoulder line, which is clearly visible from behind and supports the lowered-look greenhouse. The twin pipe exhaust system, with two polished exhaust covers, is integrated into the rear bumper, which features an elegantly curved wing.

Also contributing to the special appearance of the Mercedes-Benz Shooting Break concept car is the exceptional paint finish. A satin-finish clear coat has been used, which gives the vehicle's allanite grey magno colour a mysterious glint and also further brings out the Coupé's exquisite lines.

The sporty look of the Shooting Break concept car is complemented with large 20-inch sterling silver wheels, featuring a special bionically arranged five-spoke filigree design. They allow a glimpse of the large brake discs behind. The front wheels are fitted with 255/30 ZR 20 tyres, while the rear of this exceptional vehicle sits on 285/25 ZR 20 tyres.

The interior: design makes quality noticeable; high-quality materials, hand-crafted perfection
A large panoramic glass sunroof provides a glimpse into the high-quality, perfectly hand-crafted interior of the Shooting Break concept car, where natural materials such as wood and leather dominate. Wood is used on the trim elements and door pulls, the instrument panel and centre console, and primarily on the luggage compartment floor in the rear. When it came to choosing the wood, the interior designers opted for silky oak on account of its unusual, lens-shaped texture. The wooden floor in the luggage compartment has inlaid aluminium protective loading strips, and is reminiscent of finishes normally seen in yacht building.

Four saddle bags along the sides of the luggage compartment are useful for storing small tools. They are finished in leather, a material which has been used extensively throughout the Shooting Break concept car: in fact, almost ten square metres of leather have been incorporated into the interior. Light sections of porcelain-coloured nappa leather form an attractive contrast to the dark-brown natural-coloured aniline leather and perforated metallic-silver finish seat cushions and door centre panels. Extensive double-lapped stitching and discerning colour-coordinated upholstery seat piping reflect the hand-crafted perfection and attention to detail, as does the tuck stitching on the instrument panel, door sill covers and seat backrests, all of which highlights the contours of the components extremely well.

Perfection and attention to detail also apply to the trim elements. While on the exterior they are polished to a high-sheen finish, in the interior they feature a matt finish. A total of seven manual processes are necessary - from grinding to polishing - to transform the components, which are milled completely from aluminium, into their final decorative form. The matt finish of the interior trim has also served as inspiration for the metallic-silver leather on the seats, door centre panels and bags in the luggage compartment. The deep-pile carpet in the footwell - finished in porcelain colour - is a luxurious material used by Maybach-Manufaktur. The light-coloured roof liner made of silk cloth adds the finishing touch to the impression of comfortable elegance in the interior.

The Shooting Break concept car is clearly a four-seater. The four identically shaped leather seats have a touch of the sports car about them thanks to their integrated head restraints. Openings in the upper area of the backrests make it possible to see through the seats. A large full-length wood console on the transmission tunnel provides a visual divide between driver and front passenger and at the same time indulges the occupants with two large leather-covered armrests. It also houses two cup holders as well as controls for the rear-compartment air conditioning. The centre console is finished off at the rear with inlaid work: curved Mercedes lettering which harks back to the style of the 1920s. The striking cursive-script lettering is also repeated on the front door sills.

Since the central screen has been integrated into the upper part of the instrument panel, the cockpit has a "wrap-around" effect. The elegant verve and bionic details of the exterior are captured, among other things, in the dynamic wave-design air vents in the instrument panel. An analogue clock sits in the centre. The instrument cluster comprises three tubes for dial-type gauges as well as a colour display for service indications.

The headlamps: exciting LED technology offering full functionality
The Shooting Break concept car has dynamic full LED headlamps, which combine the exciting daylight colour impression of LED technology with the performance, functionality and energy efficiency of today's bi-xenon light generation. The new light system, due to make its debut in series production this year, features the Intelligent Light System which has already been tried and tested in Mercedes models with bi-xenon headlamps. Its five light functions - country lights, motorway lights, enhanced fog lights, active curve lights and cornering lights -have been specifically designed for typical driving or weather conditions.

The light specialists at Mercedes-Benz have also been able to combine LED technology with the innovative Adaptive Highbeam Assist for the first time, leading to a completely new level of safety at night.

The engine: enhanced performance, enhanced efficiency
The Shooting Break concept car is driven by the forerunner to the forthcoming new V-engine generation from Mercedes-Benz. The special features of the spray-guided direct injection engine include the latest generation of piezo-electric injection valves which enable multiple injections. Better lean operation is possible thanks to load monitoring of the pressure information. Even the operation of the ancillary components has been made efficient and there is also a start/stop function. The V6 with a 60° cylinder angle and displacement of 3.5 litres produces 225 kW (306 hp) with a maximum torque of 370 Nm.

It's all in a name: the origins of the name "Shooting Break"
Break, or the homonym Brake, was the name once given to carriages used to "break" in wild horses and also to restrict (or "brake") their urge to move, so that they could be put to use as work horses. Since the carts could easily be broken as part of this process, people tended not to use ones which they may have urgently needed for other purposes. Where necessary, "Brakes" were often fitted out with variable bodies, which were only really used to carry along anything that may have been necessary for the hunt, for example. Any such vehicle which was used when going out shooting was called a Shooting Brake or Shooting Break. In the 1960s and 1970s motorised Shooting Breaks were popular in Great Britain - exclusive cross-over vehicles, which combined the luxuriousness of a coupé with the luggage space of an estate.
