Arnoux left Renault in and American Eddie Cheever replaced him as Prost's partner, allegedly because of Renault's desire to sell more road cars in North America (three of the season's 15 races were on the North American continent). Prost earned a further four victories for Renault during the season and finished second in the Drivers' Championship, two points behind Nelson Piquet. Piquet and the Brabham team overhauled Prost and Renault in the last few races of the season. Prost, who felt the team had been too conservative in developing the car, found himself increasingly at odds with Renault's management, who made him the scapegoat for failing to win a championship. In addition to that, the French fans recalled the bitter fight that had caused their favourite, Arnoux, to leave the team. Prost said in an interview with ESPN during the final race that his car was "not competitive" and that he "didn't lose by my own fault" Renault fired Prost only two days after the South African race. He re-signed for McLaren for the 1984 season within days and moved his family home to Switzerland after Renault factory workers burned the second of 2 of Prost's cars, one of them being a Mercedes-Benz.
