Because of its tight confines, slow average speeds and punishing nature, Monaco has often thrown up unexpected results. In the 1982 race René Arnoux led the first 15 laps, before retiring. Alain Prost then led until four laps from the end, when he spun off on the wet track, hit the barriers and lost a wheel, giving Riccardo Patrese the lead. Patrese himself spun with only a lap and a half to go, letting Didier Pironi through to the front, followed by Andrea de Cesaris. On the last lap, Pironi ran out of fuel in the tunnel, but De Cesaris also ran out of fuel before he could overtake. In the meantime, Patrese had bump-started his car and went through to score his first Grand Prix win.
