Renault R29 - new front wing endplates 14 July 2009

Renault introduced this new front wing endplate on Fernando Alonso's car in Germany at the weekend. Notable features are the strange, curved shape at the rear of the endplate and the new longitudinal slot (black arrow), also seen previously on the Toyota. The slot acts as a kind of sealing skirt for the endplate, accelerating airflow and directing it outwards, hence allowing the front wing to work more efficiently.
