McLaren MP4-23 - rear wing 16 March 2008
McLaren's MP4-23 features an interesting rear wing, which has been deeply revised both in terms of its main profile and its endplates. These endplates still sport the now atypical horizontal slits, which reduce the turbulence generated by the impact of the airflow where they attach to the main profile. The endplates' flap (red arrow) also features a revised solution, similar to one introduced by Renault two years ago. On the MP4-23 the flap is separated from the rest of the endplates by a deep cut. This provides a cleaner exit for the airflow passing under the main sculpted profile. The efficiency of the rear wing and the overall driveability of the car has been thus increased, while the additional downforce is not negated by increased drag on the straights.
