alt Hacker NewsOptimal aerodynamic efficiency on a 4 wheel car still requires a narrower rear, with a corresponding shorter rear axle to make the rear wheels roll in the slipstream of the front wheels. This can be seen on two of the most aerodynamic cars of all time, the GM EV1 and Mercedes EQXX.
>make the rear wheels roll in the slipstream of the front wheels.
thanks. That is in general what i meant by saying "4 wheels which are only 2 vertical columns resisting the upcoming air", i missed the shorter axle as being the most aerodynamic, and your description is just much better and more right detail level correct.
