McLaren MP4-22 - rear-end bodywork development 12 May 2007
In addition to their new front wing, McLaren also introduced some interesting rear-end changes in Spain. The bodywork close to the clearly-visible exhaust pipes (upper arrows) now looks slightly lower and the flip-ups in front of the rear wheels now feature a different vertical endplate with a sculpted lower edge (lower arrows). The changes reduce the negative influence of the turbulence generated in this area by the rear wheels' rotation. The flip-ups can now generate slightly more downforce aswell as reducing drag.
