2006 trends - double rear winglets 13 December 2006

These were orginally introduced by Renault in 2005 and retained on the R26. However, it was arguably Ferrari (left) who best interpreted the function of these additional wings, adding them in the latter part of the season, with notable modifications at Hockenheim, to improve the airflow management in front of the rear wheels. The result was reduced drag and better extraction of air from the rear diffuser's side sections. Many teams adopted the same concept, but not quite as neatly. Williams (top right) improved their aerodynamic performance with a very complex solution, featuring a wide vertical pillar below the winglet to divert airflow towards the centre of the car's rear end. A similar solution was featured on the Honda (bottom right), with Super Aguri and Spyker also on the same wave length.
