The most famous of the schemes to promote young drivers dates back to the start of the 1970s, when Francois Guiter of Elf established what was known as the "Volant Elf". The fastest drivers on each course at the Winfield Racing Schools, Magny Cours and Paul Ricard, were asked to return to the school in the autumn to establish the fastest driver of the year. The two winners were each given a full budget to race the following year in Formula Renault. If they were fast enough they would be retained by Elf in Formula Three and then Formula Two (or later Formula 3000), and eventually they would get a drive in Formula One. The first two "Pilotes Elf" were Patrick Tambay and Didier Pironi. Both went on to win Grands Prix.
