second place was a lucky one though as Nigel Mansell was in second for much of the race. However, as it was his last race with Lotus before joining Williams in 1985, Lotus boss Peter Warr refused to give Mansell the brakes he wanted for his car and the Englishman retired with brake failure on lap 52. As Lauda had passed the Toleman of rookie Ayrton Senna for third place only a few laps earlier, Mansell's retirement elevated him to second behind Prost. Lauda had signed an initial letter of intent to leave McLaren team and join Renault for the 1985 season. The agreement was not implemented and Lauda stayed with McLaren for the 1985 season. The 1985 season was a disappointment for Lauda, with eleven retirements from the fourteen races he started. He did not start the Belgian Grand Prix at Spa-Francorchamps after crashing and breaking his wrist during practice, and he later missed the European Grand Prix at Brands Hatch; John Watson replaced him for that race. He did manage fourth at the San Marino Grand Prix, 5th at the German Grand Prix, and a single race win at the Dutch Grand Prix where he held off a fast-finishing Prost late in the race. This proved to be his last Grand Prix victory, as after announcing his impending retirement at the 1985 Austrian Grand Prix, he retired for good at the end of that season. Lauda's final Formula One Grand Prix drive was the inaugural Australian Grand Prix in Adelaide, South Australia. After qualifying 16th, a steady drive saw him leading by lap 53. However, the McLaren's ceramic brakes suffered on the street circuit and he crashed out of the lead at the end of the long Brabham Straight on lap 57 when his brakes finally failed. He was one of only two drivers in the race who had driven in the non-championship 1984 Australian Grand Prix, the other being World Champion Keke Rosberg, who won in Adelaide in 1985 and took Lauda's place at McLaren in 1986. Helmet Lauda's helmet was originally painted plain red with his full name written on both sides and the Raiffeisen Bank logo in the chin area. He wore a modified AGV helmet in the weeks following his Nürburgring accident so as the lining would not aggravate his burned scalp too badly. In 1982, upon his return to McLaren, his helmet was
