In just four years Dennis had turned McLaren from an also-ran team into a front-runner and in 1984, with Barnard's revolutionary MP4/2 car his work was rewarded with 12 wins from 16 races and both drivers' and constructors' titles. Lauda took the drivers' crown by a half-point from his McLaren teammate Prost, with both drivers scoring more than double the tally of third-placed Elio de Angelis. While neither Lauda nor Prost were the fastest combination of the year, that title going to reigning World Champion Nelson Piquet in his BMW powered Brabham BT53 who claimed 9 pole positions, the McLaren-TAG's reliability was unmatched. As said by Clive James in commentary on the official video review of the Formula One season produced by FOCA: "Anything as fast as the McLarens fell apart, anything as reliable finished later." The following year the situation was reversed and Prost won his first World Championship while Lauda suffered multiple failures and only won one race. At his home race in Austria Lauda announced his permanent retirement from Formula One at the end of the season. McLaren finished eight points ahead of second placed Ferrari that year but the pack was closing and in , McLaren lost out to Williams, although the consistent Prost won the drivers' title. Lauda's replacement was the 1982 World Champion Keke Rosberg, who also retired from Formula One at the end of the 1986 season.
