off on entering the final corner (he claimed that Senna pushed him off) and Patrese had a gearbox failure. Mansell went on to record four more Grand Prix wins, including at the British Grand Prix. (In the final round, in Adelaide, the two Williams cars again retired, Mansell after Senna violently crashed into the back of him, and Patrese with electrical problems.) Williams won the Constructors' Championship with 164 points, 65 points more than second-place McLaren. Mansell became World Champion, scoring 108 points, with Patrese finishing second with 56 points. Placing first in nine races, Mansell had set a new record for the most wins by a single driver in one year. Despite this, there looked to be significant upheaval at Williams for 1993. Alain Prost ended his year-long sabbatical from competition following his 1991 firing by Scuderia Ferrari, and Williams was interested in bringing him in. At the same time Ayrton Senna’s contract with McLaren was ending, as was the team's engine contract with Honda, and he had long expressed a desire to pilot one of the Williams machines. Patrese decided to leave the team in the midst of this, joining Michael Schumacher at Benetton. Prost would eventually come to terms, and this would cause a domino effect that reached beyond F1 and into the PPG IndyCar Series as well. Mansell and Prost had been teammates at Ferrari in 1990, and friction between the two drivers almost led to Mansell retiring from driving altogether after the season. Thus, Mansell had no desire to race with Prost as his teammate again and decided to take his driving acumen elsewhere. As it so happened, A seat was opening up at Newman/Haas Racing in the IndyCar Series as Michael Andretti, the 1991 series champion, was joining the Formula One World Championship for 1993 replacing Gerhard Berger at McLaren. Mansell, thus, signed to drive for Newman/Haas alongside Michael's father Mario Andretti. As noted above, McLaren was also losing its Honda engine supply at the end of the 1992 season. Senna had been hoping the team would be able to get a supply of engines from Renault, and when they were not able to convince Renault to do so Senna decided to approach the Williams organisation with an offer to drive in Patrese's old ride and do so without collecting a salary. However, as part of the terms of the contract he signed with
