1979 saw Renault expand to run a second car for René Arnoux. Jabouille secured Renault's first Formula One pole at the South African Grand Prix, and then won their first victory, fittingly at the French Grand Prix, also from pole. This was the first victory for a turbocharged car in Formula One. He took two more poles, at the German and Italian Grands Prix, but poor reliability meant the win was his only score.
