Irrelevant as long as the Reynolds numbers are similar. |
As long as the Reynolds number and the shape are similar, which they are not.
You could expect cars with a round rear end, like a Taurus, to behave somewhat like a golf ball and benefit from carefully placed vortex generators near the trailing edge. You should not expect VG's to benefit cars that already have good aerodynamics, though.
Due to their lack of scientific rigor, Mythbusters stopped short of conclusively proving anything, though.
