McLaren MP4-26 - new front wing 29 October 2011
McLaren have brought a new front wing to India. Drivers Jenson Button and Lewis Hamilton completed back-to-back comparisons on Friday and Hamilton eventually used the new version (see lower drawing) during qualifying and the race. Button, meanwhile, used the old version (see upper drawing). The new front wing has a straight main profile (2) and no longer features the indentation which divided the airflow under the car (1). There are also different upper flap mountings, although both solutions are reminiscent of ones used in 2010 before the team introduced the stepped main profile.
