Dijon was last used in 1984, and by then turbo-charged engines were almost ubiquitous, save the Tyrrell team who were still using the Cosworth V8 engine. The international motorsports governing body at the time, FISA, had instituted a policy of long-term contracts with only one circuit per Grand Prix. The choice was between Dijon and Ricard – the small Prenois circuit had cars lapping in the 1 minute 1 second range, and Ricard was the main testing facility for Formula One at the time. So it was Ricard that was chosen, and it hosted the race from 1985 to 1990. From 1986 onwards Formula One used a shortened version of the circuit, after Elio de Angelis's fatal crash at the fast Verriere bends. De Angelis was not injured by the crash, however his car caught fire and there were no marshals to help him as it was a test session, and he died of smoke inhalation in hospital the next day. These two fast corners and the whole top section of the circuit was not used for the last five races. Prost won the final three races there, the 1988 one being a particularly dramatic win; he overtook his teammate Ayrton Senna at the Curbe de Signes at the end of the ultra fast Mistral Straight and held onto the lead all the way to the finish, and the 1990 (by which time turbo-charged engines had been banned) event was led for more than 60 laps by Italian Ivan Capelli and Brazilian Maurício Gugelmin in underfunded, Adrian Newey designed Leyton-House cars – two cars that had failed to qualify at the previous event in Mexico. Prost, now driving for Ferrari after driving for McLaren from 1984 to 1989, made a late-race charge and passed Capelli to take the victory; Gugelmin had retired earlier.
