his last F1 race. 1971 saw American Mario Andretti win his maiden Grand Prix, on debut for Ferrari. 1974 saw American Peter Revson crash horribly at Barbeque Bend during testing for the race and slam head-on to the barriers; he later died from his injuries. Argentine Carlos Reutemann won for the first time at that year's event. 1975 saw South African Jody Scheckter take victory. The 1977 event was the location of one of the most gruesome crashes in history, as Tom Pryce was killed when he hit and killed track marshal Jansen Van Vuuren at full speed. Niki Lauda won the race, but the accident sent shock waves throughout the sport. 1978 saw Ronnie Peterson take a late victory from Patrick Depailler and Riccardo Patrese; the 1979 event was held in changeable weather conditions and was won by Canadian Gilles Villeneuve. Going into the 1980s, turbo-charged cars began to dominate the Grand Prix. Because of the high altitude of the fast Kyalami circuit (approximately 6,000 feet above sea level) the forced induction turbo engines could regulate how much air went into the engine whereas the normally aspirated engines could not; the turbo-charged engines had a horsepower advantage in 1982 of 150 hp over the normally aspirated engines, and often qualified on the front row of the grid considerably faster than the normally aspirated engined cars; and the Renault team dominated both the 1980 and 1982 races; Frenchman Alain Prost won the 1982 race after he lost a wheel around mid-distance; he charged through the field and took victory from Carlos Reutemann. The 1981 event was a victim of the FISA–FOCA war. As agreement could not be reached with FISA for the Grand Prix to be run as a round of the Formula One World Championship or as a non-championship Formula One race, it was officially staged as a Formula Libre event. Consequently, it was contested only by the FOCA-aligned teams, with cars which did not strictly comply with the 1981 Formula One regulations. The 1983 event was the last race of that season, and it saw a three-way battle for the Drivers' Championship between Prost, Brazilian Nelson Piquet and Frenchman René Arnoux. Prost and Arnoux both went out with engine problems and Piquet took 3rd place and the Drivers' Championship; Prost made scathing comments about Renault's conservative approach to developing the car, and he was fired from the team.
