McLaren MP4-25 - revised rear wing 10 October 2010

The new aero package introduced by McLaren in Japan included a revised version of the Singapore front wing, new longer exhausts, a new engine cover and a new rear wing. The team also changed the way their F-duct worked, as the new version blows on to the main plane (blue arrow, main picture) rather than the flap (blue arrow, inset). The team only had two sets of this new rear wing, so when Lewis Hamilton crashed during Friday practice and damaged it there was no spare and he reverted to the standard rear wing in the afternoon. On Saturday, after a plane and helicopter ride, a new rear wing arrived at Suzuka, but after not completing any running in the rain-hit third practice the team opted to use the standard version (inset) in qualifying and the race. The new wing also had angled gills like the Red Bull, rather than horizontal gills.
