The 1948 Swiss Grand Prix was a Grand Prix motor race held at Circuit Bremgarten, near Bern, on 4 July 1948. Despite racing for nearly two hours, at the finishing line Frenchman Jean-Pierre Wimille was only 0.2 seconds behind the race winner, the Italian driver Carlo Felice Trossi. Trossi's compatriot Luigi Villoresi finished over two and a half minutes behind the pair, in third place. Pre-WWII star driver Achille Varzi was killed when he crashed during practice, and the wealthy Swiss privateer Christian Kautz died in an accident during the race.
