end of that year Prost had the honour of notching up his 4th consecutive No.1 driver of the year by the editor of the Autocourse annual, matching Niki Lauda's run of No.1's from 1975 to 1978 in the same annual. Writing in 1987, the Autocourse editor mentioned that despite driving a down on power engine (compared to the Honda's) "Prost should have won at least 6 races in 1987 – but he won't moan about it. Despite being out of championship contention, 1987 was a memorable year for Prost. His win at Estoril was exceptional." In 1985, the Autocourse editor wrote of Prost: "In the long run, Ayrton Senna may be the better driver, but in 1985 for speed and consistency Prost had no equal", while in 1986, the Autocourse editor commented on Prost's season "Alain had an almost faultless year. 1986 was a year of Prost's outstanding all round ability." 1988 Despite Nelson Piquet winning the 1987 Drivers' Championship and Williams winning the Constructors' Championship, Honda decided not to supply the team with their engines, reportedly due to Williams's refusal to dump Nigel Mansell and hire Japanese driver and Honda test driver Satoru Nakajima (who debuted with Lotus in 1987), and instead supplied the McLaren team for . Prost had convinced Ron Dennis to sign Ayrton Senna to a three-year contract, which played a role in luring Honda (Senna's ability had been highly regarded by the Japanese giant when using their engines with Lotus in 1987 and both were keen to continue their association). However, this began the rivalry that pushed two of the sport's greatest drivers to unprecedented heights of success and controversy. McLaren-Honda dominated the season, winning 15 out of 16 races. Prost finished first or second in every race other than his two retirements at Silverstone and Monza. He won seven races and in total outscored his new teammate Senna by 11 points, despite Senna winning one more race than him. However, only the 11 best results from the season counted toward the championship total, and this gave Senna the title by three points. Prost went on to be a proponent of essentially the 1990s scoring system: all points counting toward the final results, with a race winner scoring 10 (rather than 9). In November of that year, Prost had a meeting with the head of Honda's R&D department and F1 racing program, Nobuhiko Kawamoto in
