Renault R26 - front-wing development 20 October 2006
Not surprisingly, the last race of the season sees relatively few changes. This one was introduced at the last round and remains for Brazil. The knife-edge profile on the front wing's endplate has been widened, in turn reducing the overall section of the wing elements. This is to reduce airflow disruption caused by the front wheels close to the extremities of the wing. With the airflow hitting the front wing finding less turbulence, this cuts drag and improves overall aerodynamic efficiency.
