History (Original Vehicle)

When Rudolf Uhlenhaut, the father of the 300 SLR racer, traveled to the Mille Miglia in 1955 to see the success of Mercedes up close, he also thought about providing the 300 SLR racer with a closed cockpit for long-distance events.

His ideas were realized in the form of a competition coupe with a level of performance that no other road sports car could match. During a test on a closed motorway section near Munich, the two-seater reached a speed of 290 km/h. Impressed by its exceptional performance during a 3500 km cross-country journey, the test reporter for the Swiss magazine Automobil Revue said: "We drive a car that takes barely a second to overtake everyone else and for which 200 km/h on a quiet motorway is little more than walking pace. With its insane handling in tight corners, the car seems to defy the laws of centrifugal force...

The 300 SLR racer was based on the famous W196 Formula 1 championship car of the 1954/55 season. The abbreviation SLR stands for Sport Light Race. As one of the most beautiful racing cars of all time, the new SLR was fitted with a slightly different eight-cylinder in-line engine, which was enlarged to a displacement of 3 litres. Two of the nine 300 SLR rolling chassis, 0007/55 and 0008/55, were converted into 300 SLR coupés with a closed body and gullwing doors. They were intended for use in the forthcoming Carrera Panamericana.

The body of the SLR coupe was clad in electron sheet, a magnesium alloy that is even lighter than aluminum. The semi-circular windshield offered very little drag. As with the SLR racer, the coupé driver had to operate the pedals behind the steering wheel with their legs apart. Under the hood was a longitudinally mounted eight-cylinder engine placed just behind the front axle and developing maximum torque of 234 Nm at 5950 rpm and a maximum power of 310 hp at 7400 rpm.

Due to safety concerns following the tragic Le Mans accident in June, Mercedes-Benz decided to withdraw from motorsport at the end of the 1955 season. As a result, the SLR coupe project was shelved and never put into production. Then Rudolph Uhlenhaut took over one of the SLR Coupés as a company car.

With a weight of just 1,117 kg and a speed of 290 km/h, the Uhlenhaut coupé was by far the fastest road car of its time in the world.

Although the 300 SLR coupés were no longer used in real racing, the 0007/55 chassis was no stranger to motorsport. It was used by the factory racing team as a test car at the 1955 Swedish Grand Prix in June and the RAC Tourist Trophy in September. At the Targa Florio, the last round of the 1955 sports car world championship, there was keen testing over a total of 16,695 kilometers to familiarize yourself with the 72-kilometer circuit and its 900 corners. The Mercedes team was no exception - Stirling Moss was constantly training at the wheel of chassis 0007/55. He damaged the front right of the car; the frame was warped at this point and the wishbones were bent. But that didn't stop him and Fangio from achieving a double victory with their SLR racers at the Targa Florio on October 16, 1955.
