However, despite its problems, the 312T2B was good enough to win the Drivers' Championship for Lauda, who won more through the car's reliability than outright speed. He took 3 wins, while Reutemann won once. The Constructors' Championship was also secured for a third successive season before Lauda walked out on the team before season's end after he won the championship at Watkins Glen in America. He was replaced by the fiery Canadian Gilles Villeneuve but Villeneuve could not get a handle on the T2B, as its neutral handling did not suit his oversteering driving style. Ferrari were due to run 3 cars at Mosport Park in Canada but Lauda decided to depart early because he felt Ferrari could not run 3 cars at a race without its resources being stretched.
