Mercedes-Benz 300SL
A production version of the successful 300SL racing sports car, which appeared in 1952 and won several major international events, including the Mille Miglia and the gruelling Carrera Panamericana road race.
Beyond any doubt, it was the 300SL coupe's gullwing doors that made the car so distinctive in appearance, although it would certainly attract attention regardless, for the styling is as dramatic as it is flawless. The sleek 300SL Roadster, which appeared after the coupe's demise, is equally appealing though less unique.
In the beginning a coupe, the 300SL was later developed into a handsome roadster. Both types regularly appear in concours d'elegance and sell for upwards of $250,000 at auction. Only 1400 coupes were made.
Built by Sauber as a successor to the Sauber C9 , the C11 used the same Mercedes-Benz M119 5.0L Turbocharged V8 from the C9. It was the first time that Mercedes-Benz chose to put their name on the car, instead of simply using Sauber. Although Sauber-Mercedes had been successful in winning the 1989 24 Hours of Le Mans , the team choose not to defend the title in 1990 due to the race not being part of the World Sportscar Championship schedule. The team chose instead to concentrate on winning the championship. Debuting at the first race of the 1990 World Sportscar Championship season , the car did not actually race, choosing instead to run only in practice while the team used the reliable C9 from the previous year. However, for the 2nd race the C11 did race, and was able to successfully come home with first and second. Throughout the rest of the season, the C11 won all but one race and easily took the team's championship for the year. Although the C11 was to be replaced by the Mercedes-Benz C291 for the 1991 World Sportscar Championship season , problems with the C291's new engine led Mercedes-Benz to continue to campaign the C11 alongside the C291. The C11 was able to gain three more wins in the 1991 season before the C291 fully replaced it. 
T he Mercedes-Benz C292 was a stillborn Group C prototype race car intended for the 1992 World Sportscar Championship season as an evolution of the Mercedes-Benz C291 , but never raced due to Mercedes-Benz withdrawing from sportscar racing after a dismal 1991 season. However, given the large amount of money Mercedes-Benz had invested in sportscar racing since their return, while receiving very little returns even after winning two championships and a 24 Hours of Le Mans , the decision was made to cancel the project after only a few C292s had been produced by Sauber. The exact number of C292s that were built is unknown, however one remaining copy is on display in the Sauber museum. With the cancellation, the C292 was never tested, and therefore its potential in comparison to its competitors was never able to be seen. It is unknown if Mercedes even got to the point of installing the M291 engine in the C292. Built by Sauber for Mercedes-Benz , the C292 featured the same Mercedes-Benz M291 3.5L Flat-12 which had initially disappointed in 1991, but during the offseason continued development and testing and was finally able to produce power similar to Jaguar , Peugeot , and Toyota . 
The technology used to beat McLaren on the track is currently bred into the new CLK GTR Roadster. The basis of our roadster is a race-proven, carbon fibre monocoque. Protection for the occupants is provided by an integrated steel roll cage with rigid crash-impact boxes.
A familiar six-liter, Mercedes V12 is the center piece of the roadster. AMG have refined this engine to include an increase in capacity from 6.0 to 6.9 liters. Other key features include an entirely new intake system and revised exhaust headers. The complete system allows the GTR to lash out 610 horsepower to it's rear wheels.
