Lauda won a third world championship in 1984 by half a point over teammate Alain Prost, due only to half points being awarded for the shortened 1984 Monaco Grand Prix. His Austrian Grand Prix victory that year is so far the only time an Austrian has won his home Grand Prix. Initially, Lauda did not want Prost to become his teammate, as he presented a much faster rival. However, during the two seasons together, they had a good relationship and Lauda later said that beating the talented Frenchman was a big motivator for him. The whole season continued to be dominated by Lauda and Prost, who won 12 of 16 races. Lauda won five races, while Prost won seven. However, Lauda, who set a record for the most pole positions in a season during the 1975 season, rarely matched his teammate in qualifying. Despite this, Lauda's championship win came in Portugal, when he had to start in eleventh place on the grid, while Prost qualified on the front row. Prost did everything he could, starting from second and winning his 7th race of the season, but Lauda's calculating drive (which included setting the fastest race lap), passing car after car, saw him finish second behind his teammate which gave him enough points to win his third title. His 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 F1 rookie Ayrton Senna for third place only a few laps earlier, Mansell's retirement elevated him to second behind Prost.
