Grand Prix racing returned after World War II, and the Bremgarten track remained the home of the Swiss Grand Prix. The first post-war race was won by Frenchman Jean-Pierre Wimille, and in 1948 it was designated the European Grand Prix, in a time when this title was an honorary designation given each year to one Grand Prix race in Europe. This event saw veteran Italian racer Achille Varzi die during a rain-soaked practice session in an Alfa Romeo. Helmets were not compulsory in those days, and Varzi, whose Alfa had overturned during the accident, was crushed by the car (Varzi was not wearing a helmet, and cars did not have roll-over protection in those days). The race also saw Swiss Christian Kautz die in a Maserati after going off the road and crashing into an embankment at the second Eymatt corner; the race was won by Carlo Felice Trossi. Frenchman Maurice Trintignant was nearly killed in another accident after crashing and being thrown out of his car and landing unconscious on the track. Three drivers including Nino Farina went off and crashed while trying to avoid the motionless Frenchman, who survived after multiple serious injuries and spending 8 days in a coma.
