McLaren MP4-25 - revised rear diffuser 16 May 2010
The latest version of McLaren's diffuser is very similar to the one introduced by Renault, with double longitudinal profiles (yellow-highlighted area). However, there are differences to the French team's solution. The side diffuser is less angled (1), very long and has a unique profile in its end section. There is also a new, small flap (2) and an additional one (3) under the deformable structure, which is designed to boost suction of air from underneath the car.
