McLaren MP4-21
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 with red stripes 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. The MP4-21 was the first McLaren car to be powered by purely Mercedes-Benz engines after 11 years partnership with Ilmor as an engine builder.
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, with an apparent improvement in reliability countered by an underpowered Mercedes engine. McLaren did not win a race all season, for the first time since. 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.| Year | Team | Engine | Tyres | Drivers | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | Points | WCC |
