2006: Adaptation of the zero keel

By on

Honda, BMW, Toyota and Midland have all chosen for the zero keel, thinking that the aerodynamic benefits would outweigh the disadvantages in front suspension geometry. Looking backward, it were still single (or V) keeled designs that ruled. None of the teams have performed very well in twisty circuits, apart for Button's Honda that prof... Read more
