a rear tyre failure at and crashed out. The Williams team then pitted Piquet to change tyres as a safety precaution, while Prost had already pitted earlier due to a puncture and did not need to change his tyres again. He then held the lead ahead of a charging Piquet to the chequered flag and the Championship. Prost became the first driver to retain the title since Jack Brabham in 1960. Another memorable race that year for Prost was at the . He was cruising to victory when his car began to run out of fuel three corners from the chequered flag. Frantically weaving the car back and forth to slosh the last drops of fuel into the pickup, he managed to keep it running just long enough to creep over the line and win the race. Prost commented after the race that when his car started running dry he immediately thought to himself "shit, I am going to lose this race again", referring to his 1985 disqualification at Imola. It happened again at the : while running in fourth position, Prost's car ran out of fuel on the finishing straight of the last lap. Instead of retiring at a time in the season when points were critical, Prost got out of his car and tried to push it to the finish, to great applause from the crowd. The finish line was too far, though, and he never reached it. He was eventually classified sixth in the race, as the seventh-placed car (the Brabham-BMW of Derek Warwick) was a lap behind. Prost also finished sixth at the , where he collided with Gerhard Berger in the Benetton. As a result, the car's front suspension and engine mountings were bent, which badly affected its handling. It would behave one way in left hand corners and a completely different way in right hand corners. McLaren Technical Director John Barnard said afterwards that the car was "bent like a banana" upon the teams' post-race inspection of the car. 1987 With Rosberg retiring from Formula One at the end of 1986 season, underrated Swede Stefan Johansson filled the McLaren seat alongside Prost for the season. Even though McLaren had introduced the new Steve Nichols designed MP4/3 after three seasons with the MP4/2 model (Barnard had departed for Ferrari), the TAG engines were not the force they had been previously, lagging behind in power and
