Most of the drag was frontal area, and the only thing stopping me cutting it was the driver's eyeline.
An outgoing body shell on a vehicle whose entire purpose is fuel efficiency, where drag is most of what there is to win.
Ran the whole aerodynamic analysis and shape optimisation for a new generation of car, cutting drag principally by reducing frontal area while holding the driver visibility requirement.
A predicted drag reduction of nearly 35% against the outgoing car, in CFD.
The 35% is a CFD prediction. The body was manufactured but the car never raced it, so the number I would most like to have is track data to put against the model.
