McLaren MP4-27 Mercedes

The continuation of the double world-champion driver line-up, further consolidation of the championship-winning engineering team and a subtle, yet deep-reaching technical update of the car all underpin the world-class strength, experience and ambition that exists at Vodafone McLaren Mercedes ahead of the 2012 FIA Formula 1 World Championship.

The presentation of the MP4-27 at the McLaren Technology Centre showcased a natural evolution of last year's six-race-winning car and underlined the message that the new season is very much one of growth through strength and continuity. After finishing second in both the drivers' and constructors' championships in 2011, the aim for the new season is to fight for both world titles from the very start of this year's campaign.

While the all-new Vodafone McLaren Mercedes MP4-27 closely resembles last year's multiple race-winning car, the 2012 chassis has been substantially revised from the ground-up, with all major systems updated or re-designed for the new season. The most evident visual differences include more tightly waisted rear bodywork, developed to improve flow to the rear of the car, and a revised cooling system, which re-directs the gearbox oil-cooler. Last year's U-shaped sidepods have also been re-designed - a legacy of the FIA's new exhaust regulations that redefine the shape of the rear bodywork.
