 Pre-war great and three-time Swiss GP winner Rudolf Caracciola was competing in a support sportscar race and crashed into a tree, and the violent accident that ensued ended up breaking one of his legs, which effectively ended his long racing career.1953 saw Ascari battling back after a pit stop to fix the misfiring engine in his Ferrari; he came back out in fourth and stormed round the circuit, passed Fangio in a Maserati, his teammates Farina and Mike Hawthorn to take victory.Ascari also won his second Drivers' Championship at that event.
