1952: Impressive performance of 300 SL in sports-car races
The Mercedes-Benz 300 SL was developed for the first official races. It was based on the 300 series, which had been built in saloon, coupé and convertible versions. The 3-litre, six-cylinder in-line engines generated 115 hp of power. This was, of course, insufficient for motorsport competition. Its output was therefore boosted to 175 hp.
The vehicle was developed by the experienced design engineer, Rudolf Uhlenhaut. Its first competition was the classic Italian endurance race Mille Miglia. Karl Kling engaged in a long battle with a Ferrari and was ultimately forced to yield to his opponent after experiencing technical problems.
The Mercedes pilots Kling, Lang and Rieß enjoyed a spectacular three-way triumph in the next race in Bern (Switzerland). Rudolf Caracciola held the lead on occasions but then collided with a tree after experiencing brake problems. The world's most famous pre-War driver recovered from the accident but his racing career was over.
The double Mercedes victory in the Le Mans endurance race attracted enormous public interest. After 24 hours, Hermann Lang and Fritz Rieß were first across the finishing line, followed by team colleagues Theo Helfrich and Helmut Niedermayr. The 300 SL went on to secure the first three positions in the sports-car race at the Nürburgring.
Mercedes-Benz also beat off the competition at the Carrera Panamericana event. The 3300 km race, which took place in part on unstable Mexican roads, at icy altitudes and in humid lowlands, stretched both man and machine to the limit. The Kling/Klenk team experienced a major adrenaline rush when a vulture smashed through the windscreen at 220 km/h and came to rest in tatters inside the vehicle. The fact that they were still first to be shown the chequered flag demonstrates both the technical superiority of the 300 SL and the driving abilities and undaunted spirit of Karl Kling and Hans Klenk.
In producing the victorious 300 SL, Mercedes-Benz showed they were capable of mirroring their pre-War success.
