He was back with Ferrari for the start of the 1955 season in Argentina, taking morphine injections to ease the pain. But the heat took its toll on all of the drivers. Farina pitted due to exhaustion, with his Ferrari 625 being taken over by the team's spare driver, Maglioli. When José Froilán González pitted, a revived Farina was sent out in his place. Later in the race, González – who was back in his car – crashed but rejoined and handed the car back to Farina, who brought it home in second. Third place in the 1955 Argentine Grand Prix went to Farina's original car which had been drivern by Maglioli and Maurice Trintignant. After a third place in Belgium, Farina retired mid-season, owing to the continued pain and the death of Ascari. He returned for the 1955 Italian Grand Prix, but his Scuderia Ferrari-entered Lancia D50 suffered a tyre failure at 170 mph during a practice session, whilst on the Monza's new banking. The car spun, but Farina stepped out unhurt. Ferrari withdrew the car from the event, and Farina did not start his final Grand Prix.
