Career
Sage came from a wealthy background and was a collector of Ferraris, making his competition debut at the age of just 20 years old co-driving a Ferrari 250 with André Simon. He also co-drove for Jean-Pierre Hanrioud and Gérard Larrousse while competing in Formula Three through the early 1960s. Then in 1973 along with Larrousse and Paul Archambeaud, they established the Écurie Elf team Switzerland.
Archambeaud was a Swiss Mercedes-Benz dealer at the time.
They began work building sportscars, but soon switched focus to the European Formula Two Championship series where they guided Jean-Pierre Jabouille to the 1976 championship. When Larrousse was recruited by Renault, he hired Sage to run the newly forming F1 team in 1977.
Sage stayed with Renault until the end of 1987, when it stopped supplying its turbo engines to other teams. After Renault, Sage went to manage the running of Ferrari F40"s in the IMSA GT series through 1989 and 1990 with even Jean Alesi racing for the team
Into his later life he remained an active Ferrari collector and competitor in classic racing events, before his death on October 8, 2009.
