Renault R25 - rear-light wing 29 May 2005
Already seen on other cars, at the Nurburgring Renault introduced a small wing on top of the rear light. Roughly 15 cm wide, it is connected to the light cover and crushable structure by means of a tiny pillar. This device helps with the extraction of air from the bottom of the car by means of a depression that it creates right behind the rear diffuser's central section.
