Prost was tired of Renault's inability to put together a consistent challenge for either championship and was sacked at season's end after publicly criticising the team for their lack of development on the RE40. He would join McLaren at the end of the year. The RE40 took four wins and three poles during the season. However, Prost enjoyed driving the RE40 and later commented that it was ""a lovely car ... we should have been World Champions 10 times over."" Cheever was also gone at the end of a frustrating season and would join Alfa Romeo.
