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 the 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."

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. Dennis signed Stefan Johansson from Ferrari for the season to partner Prost, but it was clear that the TAG engine was no longer competitive in the face of increased manufacturer involvement, and so Dennis approached Honda, who were at the time supplying rivals Williams and Lotus. Williams' unwillingness to accept a Japanese driver (Satoru Nakajima) in place of Nigel Mansell, as well as their displeasure with Williams team management for losing the 1986 drivers' title, led Honda to transfer their engine supply to the McLaren team. Dennis made no secret that Johansson's seat was only temporary as his intention had been to sign the Brazilian Ayrton Senna (who had developed a close relationship with Honda while at Lotus in 1987) to partner double champion Prost. Senna was under contract with Lotus for 1987 but Dennis got his man and midway through the year it was announced that Senna would be joining the team, along with Honda, for three years from . In 1988 McLaren was dominant, winning 15 of the 16 races and taking 15 of the 16 pole positions, and both the drivers' and constructors' titles with no real opposition. The team won
