Prototypes may get F1 style fins

The shark fins that have become commonplace in Formula 1 over the past two seasons look set to become mandatory on Le Mans prototypes.

A central fin is being investigated as a means of preventing prototypes from becoming airborne if they snap sideways. The idea is the result of an aerodynamic study commissioned by the FIA in the wake of a series of aerial accidents during the first half of 2005.

FIA technical consultant Peter Wright explained that the fin would “increase yaw stability if the car gets out of shape”, adding: “The effect of the fin will be to keep the car on the road.”

The idea was discussed by the manufacturers and constructors at the end of January. It was decided that fins should not be introduced until 2011, but the final rules are not expected to be finalised until the end of February.
