Spyker reintroduce WRC rear wing
Formula One car design today is basically to optimise the car's bodywork in order to make the wings and the diffuser work as efficient as possible. The slightest change in the rear wing can quickly induce an important downforce or drag change. Spyker tried to do so by bending the end plates towards the outer sides of the car. This will cause air under the wing to flow faster. Since faster air directly means lower pressure, the downforce generated by the rear wing will be increased. Ferrari attempt to achieve the same effect by adding gurney flaps to the trailing edges of the end plates. Also note the obligated gap spacers. An experienced F1 eye can already see this redevelop to the vertical panels that used to be fitted on BAR's 2004 car - a feature that was at the time copied from WRC to limit sideways draft.
It´s there on the new williams too :wink:
