Renault Alpine A 110-50 Concept2012

 
 
 
 
 
 

The Alpine Berlinette turns 50 this year and, to mark the event, Renault has created the Renault Alpine A110-50 concept car, dedicated to performance and driving enjoyment.

So what's in a name? In some cases, the heritage of a name is like a national treasure - and that's certainly true for Alpine. Its DNA blends Renault's sporting passion and technical expertise.

    The Renault Alpine A110-50 concept car translates the most characteristic design features of the original A110 in a modern and spectacular way.
    The carbon-fibre bodywork features a new shade of blue which refreshes and reinterprets the famous original 'Alpine Blue'.
    Produced with the renowned expertise of Renault Sport Technologies, the Renault Alpine A110-50 concept car is imbued with the world of motorsport. It benefits from the experience gained from the racing Mégane Trophy by using the same technical platform.

A new interpretation of a timeless design
To mark the 50th anniversary of the iconic Berlinette, Design Yann Jarsalle and Concept and Show Car Director Axel Breun reinterpreted the original design cues to include the new Renault design language introduced by Laurens van den Acker with the DeZir concept car, and which will soon be rolled out in the company's future models. The new front-end look, with the upright, confident diamond, has been adapted for this very low and wide car. The Renault Alpine A110-50 is a car of today; a bold embodiment of Renault's passion for motorsport.

The Renault Alpine A110-50 concept car translates the most characteristic design features of the original A110 in a modern and spectacular way with:
    the sculpted forms of its elegant, flowing bodywork, enhanced by lights over which air seems to flow effortlessly.
    the half-domed additional lamps, with a technical but nostalgic interpretation, thanks to full LED yellow lighting - as it should be!
    a characteristic 3D rear window, which reveals the mid-rear engine.
    air intakes on each side echo the ducts on the rear wheel arches of the Berlinette. The right-hand opening is for gearbox cooling, the left is for the engine bay.

Produced by Faster, the carbon-fibre bodywork features a new shade of blue which refreshes and reinterprets the famous original 'Alpine Blue'. Every opening panel does so with dynamics worthy of the finest GTs, with the bonnet hinged at the front and the engine bay cover opening towards the rear. The doors feature a scissor motion.

A competition-focused cockpit
As you climb into the driving seat, the eye is drawn to the carbon-fibre sills. Everything inside this two-seater expresses build quality and sportiness, with black dominant.
    the driver's seat features embroidered 'Renault Alpine A110-50' badging, Sabelt full harness belts and different, attractive shades of blue.
    the dashboard is particularly uncluttered. The Renault Design-created steering wheel incorporates a colour screen and houses the same technology as a Formula Renault 3.5 single-seater to provide drivers with all the information they need.
    Racing driver equipment is provided by Sabelt and the helmet is created by Ruby.

A true prototype
Produced with the renowned expertise of Renault Sport Technologies, the Renault Alpine A110-50 is imbued with the world of motorsport. It benefits from the experience gained from the racing Mégane Trophy by using the same technical platform. Acclaimed by drivers in the World Series by Renault, the tubular chassis of the Renault Alpine A110-50 has been stiffened and undergone several developments. The roll cage and bracing in the engine bay have been modified (lowered) in the workshop of Tork Engineering to adapt them to the vehicle's height, which is lower than that of Mégane Trophy. The digital design work was led by Renault Design, Koller and Etud Integral, while final assembly was carried out by Protostyle. The final weight distribution is almost ideal, with 47.8% over the front wheels.

To facilitate servicing, the concept car features integral pneumatic jacks. Derived directly from the systems seen in endurance racing, they allow the wheels to be changed extremely quickly.

An exceptional car that fuses elegance and aerodynamic efficiency
The efficiency of the Renault Alpine A110-50 concept car is largely generated by ground effect. At the front, a splitter hidden in the bumper generates low pressure, which results in significant aerodynamic downforce. At the rear, a diffuser accelerates air flow beneath the floor. Ground effect therefore accounts for more than one-third of the car's downforce, with the rest coming from an adjustable rear wing.

The research and design of this air flow was conducted using Computational Fluid Dynamics, a cutting-edge technology used particularly in F1. CFD involves studying movements of a fluid, or their effects, by resolving digitally the equations which govern the fluid. This technique was used by Renault Sport Technologies primarily in order to fine-tune the aerodynamics and study the behaviour of the New Mégane Trophy as a function of air flow.

Exemplary road holding
The wheelbase of the Renault Alpine A110-50 is identical to that of Mégane Trophy (2,625mm), while the track is slightly wider at 1,680mm front and 1,690mm rear.

The 21-inch wheels, with a single central nut, are specific to this car and fitted with roadhomologated Michelin tyres.

The Sachs dampers can be adjusted in compression and extension, and are mounted directly onto the lower wishbones. There are numerous different set-up options: castor, camber and alignment, ride height, anti-roll.

In order to improve driver feedback, driving aids like ABS, traction control, etc. are not fitted.

Serious stopping power
The braking capability of the Renault Alpine A110-50 match its performance. At the front, large 356mm-diameter steel discs are slowed by six-piston callipers. At the rear, the discs are 330mm in diameter, while the callipers are four-piston models.

Mechanical excellence
Developed on the same technical platform as Mégane Trophy, the Renault Alpine A110-50 concept car also boasts the same chief technical characteristics.

It runs the Renault V4Y engine block, a 3.5 litre 24-valve 400hp V6 mounted in a mid-rear position. The crankcase (semi-wet), moving parts (pistons, connecting rods, crankshaft), valve train (camshafts and valve springs) and exhaust system are specific compared to the version featured on productions models.

Furthermore, the Renault Alpine A110-50 uses the carbon air intake employed for Mégane Trophy V6.

The inlet manifold is fed by a new roof-mounted air intake. This development broadens the engine's power band, with additional horsepower at all engine speeds. The engine mapping has been optimised for these modifications.

F1-style transmission
The Renault Alpine A110-50 concept car is fitted with a semi-automatic six-speed sequential gearbox, as well as a twin-plate clutch that can be controlled using either the clutch pedal or a paddle on the steering wheel.

The gearbox is fitted longitudinally behind the engine and incorporates a limited-slip differential (discs and ramps) with adjustable pre-loading.

The cerametallic twin-plate clutch is also specific to the car. It is activated automatically when downshifting, guaranteeing fast and reliable gear changes.

A black box at the heart of Renault Alpine A110-50

Supplied by Magneti-Marelli, the Marvell 6R electronic control unit includes functions for engine management, gearbox control and data acquisition.

Even more accurate data acquisition
All data collected by the Renault Alpine A110-50 can be analysed using version 4 of the benchmark Wintax software. Wintax 4 enables advanced analysis of more than 50 parameters: engine speed, gear, steering angle, car speed, throttle position, brake pressure... This information allows drivers and engineers to optimise settings and driving style. Wintax 4 data analysis also enables even faster diagnosis of any technical problems.

"Developing this concept car was a great adventure. It was a catalyst for creativity. We wanted to make a Berlinette that was of our time, and which boldly embodies Renault's passion for motorsport. We were guided by our hearts and emotions." - Axel Breun.

Renault Alpine A110-50 - The legacy of the Berlinette
When Jean Rédélé unveiled the A110 Berlinette at the 1962 Paris Motor Show, it marked the start of an Alpine adventure for the engine from the Renault 8. The car had been developed from the Alpine A108, but was more stylish and more dynamic, with an even lower engine cover, a larger glazed area and the rear lights from the Renault 8. The new engine demanded changes to the air intakes: with the radiator mounted at the rear, cooling exits were opened in the resin bodywork behind the rear wheel arches, disguised with four chrome strips. The changes served only to heighten the elegance of the A110 Berlinette. The restrained, balanced silhouette maintained its extremely pure lines.

A car for the enthusiast
To drive a Berlinette is a life-changing experience. Above all, it was designed to win rallies, so it's not surprising that it boasts a certain pedigree; not a tricky personality, but real character. You don't climb aboard an Alpine, you slide into it. But once you're behind the wheel, the connection is immediate. Agility and traction are particular strong points thanks to the mid-rear position engine, which tends to produce oversteer that is easy to control using the steering and throttle. It's sometimes a little trickier to keep going in a straight line, but life's all about compromise... This isn't a car you simply take for a drive - it demands to be properly driven. Its weaknesses are also its strengths.

The Berlinette in motorsport
The light weight and handling qualities of the Berlinette meant it was perfectly suited for motorsport. As well as being fun to drive, the cars were favourites with the fans, who often saw them cornering hard at lurid angles. It's almost impossible to catalogue every motorsport triumph for the Berlinette, but these are the main stages of the adventure.

1961-1968: the early successes
José Rosinski took the first win for the A110 at the 1963 Rallye des Lions. The remainder of the season followed this trend, with exploits including a win for Jacques Cheinisse on the Rallye d'Automne.

In the years that followed, a number of 'privateer' drivers achieved success at national and international level ahead of much more powerful cars from well-established brands.
1967: assembling a great team

Alpine became Alpine-Renault. New drivers joined the line-up: Gérard Larrousse, Jean-Claude Andruet and Jean-Pierre Nicolas in the works team, but also, among others, Bernard Darniche in the privateer ranks.

1968: the first French Rally Championship title
After victories on the Neige et Glace and Rallye de Lorraine for Gérard Larousse, Jean-Claude Andruet claimed the French title thanks to a total score of four wins during the season.

1969: Hitting its stride
Jean Vinatier and Jean-Claude Andruet were the stars of the season, with the former going on to become the French Rally Champion at the end of the year.

1970: European and French titles
The Berlinette 1600S was homologated for Group 4, which finally allowed the car to fight on almost equal terms with more powerful competitors. Jean-Claude Andruet, who had calmed his approach after several notable incidents, was crowned French and European Champion.

1971: The Berlinette dominates the Rallye Monte-Carlo
Another good year. Ove Andersson won the Rallye Monte-Carlo. Thérier finished second and Andruet third. Andersson also took the win in Italy against the flotilla of Fiats and Lancias dispatched to beat him. He subsequently triumphed on the Austrian Alpine Rally and on the Acropolis, securing the international title for Alpine. Jean-Pierre Nicolas won the French Championship.

1972: Heading for glory
The 1,600cc engine was replaced by a more powerful 1,800cc unit. Jean-Claude Andruet dominated the Tour de Corse. Numerous wins followed, shared between the team's drivers. Darniche was crowned French Champion at the end of the year, while Jean-Luc Thérier claimed the Rallye des Cévennes driving a turbocharged 1,600cc version. This was the first stirrings of a technology destined for major success...

1973: The climax of an era
Just imagine the best French drivers of the era: Andruet, Darniche, Thérier, Nicolas and Piot ably supported by the experienced Andersson. What's more, a team of mechanics giving their heart and soul, plus a car at the peak of its development. The season began with victory for Andruet on the Rallye Monte-Carlo, followed home by four other Alpines. In Portugal, Thérier and Nicolas scored a one-two. On the Rallye du Maroc, Darniche was unbeatable. And the rest of the season followed the same trend. Alpine won the inaugural World Rally Championship title and Jean-Luc Thérier was crowned French Champion.

1974 - 1975: the end of the works era
Nicolas won the Rallye du Maroc and finished second on the Tour de Corse. This was the Berlinette's swansong, and the year produced the last major win for the A110 on the Critérium des Cévennes, driven by Jacques Henry.

Subaru BRZ, 2013

 
 
 
 
 
 
 
 


Subaru BRZ is a rear-wheel drive sports car featuring the Horizontally-Opposed Boxer engine. It was developed as a joint-project between Subaru and Toyota Motor Corporation, to bring to the world a sports car with superior steering response and driving pleasure that everyone can experience. The Subaru Boxer engine in the BRZ was positioned even lower than other Subaru models so that the BRZ has one of the lowest possible centers of gravity s on the market today. This low center of gravity produces astonishing handling character and combined with a light-weight chassis BRZ realizes Subaru's aim for "Pure Handling Delight" - the driving experience taken to a new level.

Concept
The product concept of Subaru BRZ is "Pure Handling Delight." The Horizontally-Opposed Boxer engine has inherent qualities of low center of gravity, lightweight, and compactness. These attributes are maximized by placing this engine even lower and closer to the center of the chassis. These factors contributed to BRZ's low center of gravity - one of the lowest possible. The Subaru BRZ is a fun sports car that any driver can enjoy driving with peace of mind.

Design
The Subaru BRZ has a low-mounted Boxer engine on a specially designed sub-frame that forms an "ultra-low center of gravity package". With this arrangement, BRZ achieved a low driving position typical of a sports car. Overall height of Subaru BRZ is 1,300 mm and it has a wide and low body of a stylish coupe at 1775mm. Yet, it allows for 2+2 seating and a trunk with ample space. Not only is the BRZ a sports car, but it can also be a suitable partner for long tours with its unexpected utility.

Exterior
Subaru aimed for a sports car design that instinctively conveys the car's fun-to-drive character. In addition, it was detailed to be instantly recognizable as a Subaru.

Front fascia
The "ultra-low center of gravity package" also allowed a low hood design. This low hood and bulging front fenders raise expectations for the Subaru BRZ's drivability. Also, to communicate the Subaru identity the Subaru six-star ornament, headlights and hexagon lower grille follow the Subaru design motif common across new Subaru models.

Side
The low center of gravity enhances BRZ's sensuous beauty with its shapely fender flares. The aesthetic beauty is combined with functional beauty that advances aerodynamics through such areas as the C-pillar shape, rear glass inclination, trunk lid layout. As would be expected from a sports car, the front and rear overhangs were shortened to express the Subaru BRZ's liveliness. The front fender is accentuated with a distinctive garnish.

Rear fascia
The projecting rear wheel arches sit by way of contrast to the compact cabin and emphasizes the beauty of the BRZ's rear view.

Interior
Details were carefully designed to allow a new level of fun-to-drive experience in which the driver and vehicle become one.

The steering wheel was made smaller to achieve sports car maneuverability.

A tachometer with digitally displayed speedometer is placed in the center of the gauges so that the driver can instantly see information without diverting attention from the road.

Bespoke sports car seats were designed to hold the driver and passenger and feature lowered sitting positions to match the "ultra-low center of gravity package".

Engine
Making full use of the design concept of the new-generation Boxer engine, the newly developed engine made exclusively for the BRZ is highly efficient with superior output and environmental friendliness. It realizes an exhilarating high revving nature of a naturally aspirated sports engine.

It has square bore and stroke of 86 x 86 mm.
Due to the joint development with Toyota Motor Corporation, Toyota's direct injection and port injection technology "D-4S" was incorporated in the Subaru BRZ's power unit.

To achieve the "ultra-low center of gravity package", the engine as a whole has been made more compact by such means as adopting the shorter intake manifold and the shallower oil pan.

Transmission
The joy of sports car driving was realized through a transmission that focuses on shift feel and response.

The 6-speed MT employs a short stroke shift lever. The lever was optimized in rigidity, shift quality and weight application in its pursuit of a superb shift feel.

The 6-speed AT has "S mode" for better shifting response and "M mode" for optional shifting. Also, with the paddle shift and downshifting blipping control, this model can respond faithfully to the driver's inputs.

Body
The lightweight yet highly-rigid body was developed exclusively to maximize the advantages of the "ultra-low center of gravity package".

Low center of gravity and low driving position were achieved by the perimeter type body frame layout.

The body has a rigid and durable frame structure that also works in balance with the vehicle's light-weight. The rigidity is optimized for high drivability and appropriate durability is maintained for collision safety.

High tensile steel was used in the body to contribute to weight reduction. Effective use of this material in the upper structure of the Subaru BRZ contributed to its low center of gravity.

The front hood employs aluminum for lightness. The structure was fine-tuned for a low styling that also improves pedestrian protection performance.

Chassis
Excellent maneuverability and stability of the "ultra-low center of gravity package" offers direct and sharp response to steering and enhances driver's connection to the car

The front suspension employs struts for light-weight and high rigidity, while a double wishbone layout is adopted at the rear for better shock absorption.

To gain a low front hood from the "ultra-low center of gravity package", the front strut mount was lowered while maintaining the stroke.

The tires are 215/45R17 combined with lightweight and highly rigid aluminum wheels.

All models are equipped with electronic stability control to provide both driving pleasure and safety.

Mercedes-Benz SLK Gullwing Hybrid 2012

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.


MERCEDES BENZ SLS AMG 2011

 


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.
