Renault R26 - rear wing analysis 12 May 2006

Slight changes for Spain, with better airflow management helping to cut drag on this circuit's very long straights. This is achieved by effectively reducing the sectional area of the flap and main profile (while retaining their original general design) through the main profile bending dramatically downwards towards its extremities, with the central section higher than the outer ones and supported by a tiny pillar.The flap, meanwhile, is completely flat, though of course its front edges bends downwards so as to maintain a constant gap with the main profile. The overall effect is one of sufficient downforce coupled with very low drag, the latter enhanced by the endplate side-slits that have been slightly modified to further reduce turbulence in this area.
