McLaren MP4-22 - rear wing development 20 October 2007

This solution, as with the Ferrari front wing shown previously, is designed to compensate for the low air density at the high-altititude Interlagos circuit. Air pressure is increased in the rear wing area by a greater angle to the extremities of the main profile, its boundaries limited at one end by the endplates and at the other by flap separators (see detail circle). The 'channel' created between endplate and separator helps accelerate airflow both above and below the main profile, providing performance gains not just at high speeds on the straights, but also in the slower sections of the track where rear-end grip is improved.
