Mercedes-Benz SLS AMG GT3 – Click above for high-res image gallery

AMG has been producing racing versions of Mercedes-Benz cars and high performance street machines for over four decades. That tradition continues with the unveiling today in Mexico of a GT3 spec version of the new SLS gullwing coupe. Sales will start this fall and AMG hopes to have the homologation process completed in time for the 2011 race season.

The GT3 SLS will use the same 6.3-liter V8 as the road car, but the FIA will determine its final output for racing. The aerodynamic enhancements are the big news here, with changes to the bodywork evident all over. The front end features a deep carbon fiber splitter that's only bested by the large rear wing out back. The hood sports a large cooling event and there are air intakes for brake cooling in the side skirts and cooling vents in the fenders behind the front wheels as well. Other race-spec features include a smooth underbody, rear diffuser, central-locking wheels and fuel filler pipes in the C-pillar.

Given the racing heritage of the original SL from the 1950s, seeing a gullwing back racing on the track will be the best kind of déjà vu for fans of the three-pointed star. Follow the jump for the official press release from AMG and Mercedes-Benz that includes a few more specifics.

Mercedes-Benz SLS AMG GT3

Spectacular racing car for the sporting customer

Puebla (Mexico) – Coinciding with the market launch of the SLS AMG on 27 March 2010, Mercedes-AMG is presenting a GT3 variant. This racing version of the gullwing model stands out with its spectacular design and thoroughbred motor sports technology. Developed to comply with the GT3 specifications of the FIA (Fédération Internationale de l'Automobile), the SLS AMG GT3 is designed as a racing sports car for customers competing in sprints and long-distance races. These race series for near-series GT cars are noted for their very varied participants and great excitement. Not least because of their comparatively favourable cost structure, they are enjoying increasing worldwide popularity.

AMG, the performance brand within Mercedes-Benz, is entering a new business sector with the new SLS AMG GT3: the development, production and marketing of sports racing cars intended for customer use. Sales of these customer cars are expected to commence in autumn 2010, and homologation of the GT3 variant will be completed in time for the 2011 racing season.

"Thanks to uncompromising lightweight construction and superior handling dynamics, the SLS AMG provides an outstanding basis for a highly competitive racing car. This exciting GT3 version is our response to strong customer demand for a car designed for these attractive motor sports series. Once again, it demonstrates AMG's huge experience gained in more than 40 years of motor sports, and its great expertise in the development of unique high-performance cars," says Volker Mornhinweg, Chairman of Mercedes-AMG GmbH.

The new SLS AMG GT3 is an emphatic continuation of AMG's commitment to motor sports. AMG has been a pioneer in the motor sports world ever since its foundation in 1967. The new racing version of the SLS AMG is developed and produced by AMG in close cooperation with HWA AG. HWA is responsible for the DTM racing team on behalf of Mercedes-Benz Motorsports. The HWA team is one of the most successful in international motor sports, as witness nine driver championships in the DTM and ITC, as well as two championship titles in the FIA GT Championships.

The SLS AMG GT3 is set to write another chapter in this success story, and harks back to the 300 SL racing sports car of 1952 which first established the "gullwing" legend. Its historic victory in the "Carrera Panamericana" long-distance race also made Mercedes-Benz a household name in North and Central America, and demonstrated the know-how and expertise of the Stuttgart-based automobile company.

Spectacular racing car looks and top-class performance

The new SLS AMG GT3 is wide, flat and has spectacular racing car looks. The main focus when modifying the body of this gullwing model was on aerodynamic performance – as is seen not only in the new front apron with a splitter, the bonnet with its central cooling air vent and the wider front and rear wings, but also in the the side wheel arch air vents, the sideskirts with cooling ducts for the rear brakes, the smooth underbody with a rear diffuser and the adjustable rear aerofoil. All these features ensure a low drag coefficient and maximum downforce – while guaranteeing effective cooling of thermally highly stressed components. The C-pillars accommodate the standardised filler pipes for the fast-refuel system.

The FIA will determine the maximum output of the AMG 6.3-litre V8 front-mid engine with dry sump lubrication on the "Balance of Performance" principle. This is intended to ensure that all the racing cars taking part have an equal chance. The classification process, during which the kerb weight is also determined, will be completed in 2010. Power transmission in the GT3 variant is by a sequential six-speed racing transmission with steering wheel shift paddles and an integrated multi-disc locking differential. As in the standard SLS AMG, the transmission is located at the rear axle: the engine and transmission are connected by a torque tube within which a carbon-fibre shaft rotates at the engine speed, as in the roadgoing version.

The wheels are located by a double-wishbone suspension of forged aluminium at the front and rear. Adjustment facilities for the springs and shock absorbers, the suspension height, the stabilisers, the track width and camber allow an individual setup for the racetrack. Rack-and-pinion steering with a more direct ratio and speed-sensitive servo assistance make for extremely agile handling. Behind the central-locking AMG light-alloy wheels, a composite steel racing braking system with racing ABS ensures outstanding deceleration.

Functional racing car atmosphere in the interior
The interior of the SLS AMG GT3 is dominated by a functional racing car atmosphere: the steel rollover cage not only ensures the driver's safety, but also adds additional reinforcement to the aluminium spaceframe. Another eye-catching feature is the racing buucket seat with a six-point seat belt and HANS system (Head and Neck Support). The central display is perfectly positioned in the driver's field of vision, and shows all the relevant information such as speed, engine rpm, operating temperatures, lap times and the selected gear. The open-top racing steering wheel with gearshift paddles makes perfect vehicle control possible.

Additional controls are located on the centre console. This is where the driver can not only start the AMG V8 engine or adjust the traction control, but also select reverse gear or – if the worst comes to the worst – activate the integrated fire extinguisher system. The adjustment control for the brake balance is located on the torque tube tunnel.

      very nice , but they should join GT2 if they are serious about it.
      • 4 Years Ago
      EGADS! How can you look at this "thing" and not think it's ugly as sin?
        • 4 Years Ago
        Some people call it taste.
      • 4 Years Ago
      Wow, this was not expected. Mercedes is back in GT Racing!
      • 4 Years Ago
      Awesome to see MBZ in FIA GT3. Now let's get at least 2 races in the USA from this series. Audi GT3 LMS, Corvette Z06R , Aston Vantage, Ford GT, Maserati GS, Spyker, Porsche GT3 RS, are all in this series. It's all over the world but North America. Please someone at ALMS make this happen !!!!!
        • 4 Years Ago
        yep, you lost a billion+ dollars when F1 left the united states.
        but get used it, it will happen more often.

        @ the first F1 Indianapolis in 2000 race, mechanics and crew where not allowed to enter and they where already on the airport!!!
        officials said back than, they have no work permit and therefor not alllowed to enter.
        that's bare truth, because it was anounced here on tv when it happend.

        far more than 50% of the U.S. population is as smart as a piece of rock.

        the country needs to change their mentality, it sucks.

        ALMS has these cars in the GT2 class:
        997 GT3 RSR
        Corvette ZR1
        BMW M3 E92
        Ford GT
        Ferrari 430 GT
        Jaguar XKR

        Not all the cars from your list but you make it sound like we have nothing in the states.
        • 4 Years Ago
        Never mind. I see your simply saying FIA GT needs to come to the states. Well with ALMS fields getting smaller they may be concerned about the lack of interest in the states. In the rest of the world you can probably watch FIA GT on main stream TV stations live. In the states you are very lucky to catch ALMS live and even more lucky if you can catch it live and on a main stream network. We are over saturated with NASCAR here. I love it on Speed TV when they cut into the 12 hours of Sebring coverage to cover NASCAR PRACTICE sessions. Practice... are you kidding me.

      I'm glad to see mercedes back to racing, but this just goes to show how far mercedes-benz has fallen. The cars exterior is a complete copycat blend of the nissan gtr front, mazda rx-8 rear be original not ricey!
      • 4 Years Ago
      This car is asking for a return of the back to the future series.
        • 4 Years Ago
        Are you kidding?!? this car has nothing the DeLorean had that made b2tf so good.
      • 4 Years Ago
      Anyone else feel like they ripped those head lights off a 350z? Ugly in my opinion
      • 4 Years Ago
      I don't like the spoiler, but I suppose it had to take a hit on aesthetics somewhere.
        • 4 Years Ago
        it's a race car, not a gangster car.
        you cannot drive with such wings wings and front lips on the roads.
        the car wouldn't hold a day.
        the wing is dangerous for people walking / riding bicycle on the streets.

        it's ment to race, not to look good.
