With Formula One changing to 2.5 litre unsupercharged engines for 1954, Mercedes re-entered Grand Prix racing for the first time since the Second World War at the French Grand Prix with the Mercedes-Benz W196, a streamlined single seater which Fangio and Karl Kling took to a 1–2 win. Fangio's French success had come after switching from the Maserati team, with whom he had won the first two Grands Prix of the season. Although the streamlined, closed-wheel body proved unsuitable for Silverstone, Mercedes produced a more conventional open-wheel body for the Nürburgring race; Fangio won three of the remaining four races.
