2011 cars had no winglets, and the TRD stickers on the Prius show me Toyota involvement. Also, the Prius is one of the most aerodynamic cars in the world. It's drag coe. is among the lowest in cars. I'm sure it's shape is fine. I think that GTR is 2011 car, no rules for 2012 GT500 has been given yet AFAIK.
