Villeneuve qualified ninth, splitting his two more experienced team-mates, and was running competitively when a faulty temperature gauge left him stranded in the pits for two laps.
Rejoining 21st, he charged back to finish 11th and set the fifth-fastest lap of the race.
Despite being hailed as a future world champion, McLaren didn’t keep him.
Teddy Mayer had already signed Patrick Tambay for 1978 and decided Villeneuve was surplus.
In August, Enzo Ferrari met the young Canadian and was immediately reminded of Tazio Nuvolari. McLaren’s loss became one of the most consequential gains in Ferrari’s history.

By 1973, Jacky Ickx’s relationship with Ferrari was crumbling.
The 312B3 was uncompetitive, the team was skipping races, and Ickx — twice a runner-up in the championship and winner of eight grands prix — found the situation intolerable and decided to walk out mid-season.
McLaren offered him a one-off drive in a third works Yardley M23 at the German Grand Prix at the Nürburgring, a circuit Ickx knew better than almost anyone alive, having won there in both 1969 and 1972.
The Belgian driver delivered immediately, finishing third behind the Tyrrells of Jackie Stewart and François Cevert in what was Stewart’s final victory before his retirement.
