For Caracciola, 1938 was his most successful year not just on account of his spectacular speed record. After 1935 and 1937, it was in the same year that the man from Remagen won his third European Grand Prix championship, comparable with today’s Formula One world championship title. Victorious in the Swiss Grand Prix, Rudolf Caracciola finished second twice and third once in the other three races that counted towards the European championship. His car: the Mercedes-Benz W 154, powered by a three-litre V12 engine with over 450 PS, which had a top speed of up to 310 km/h depending on the transmission and rear-axle configuration. Designed according to the newly introduced three-litre formula, the car dominated the racing action in its very first season, helping Caracciola to his third title.
