My CFD simulations show laminar flow along the majority of the body of a car.
Furthermore, the boundary layer has huge effects on flow separation. Reduction of flow separation in certain areas of a car can reduce the C pillar vortices strength. This reduction can greatly lessen the size of the wake of a car and thus reduces the induced drag.
