The McLaren MP4-21 is a Formula One car designed by Adrian Newey for the 2006 Formula One season. The car continues the MP4-X naming system and is notable for its striking chrome livery designed to maximize the visibility of the team's new primary sponsor Emirates. The distinctive needle-nose design was previously used on the MP4-19 in 2004. The MP4-21 was the first McLaren car to be powered by purely Mercedes-Benz engines after 10 years partnership with Ilmor.
The car started the season in the hands of Kimi Räikkönen and Juan Pablo Montoya, but after a few races it soon became clear that it was not as competitive as its predecessor, the MP4-20, despite an apparent improvement in reliability. McLaren did not win a race all season, for the first time since 1996. Their best results were second-place finishes for Kimi Räikkönen in Australia and Italy, for Juan Pablo Montoya in Monaco, and for Pedro de la Rosa in Hungary.
