I have not tested it for lack of practical means to do so, but it should have even better benefit in a car than in an airplane.

1. Less air resistance
2. Engine detuned a bit for cruise
3. as for advantage over an airplane, a propeller will "slip" more in thin air whereas a car does not experience such slip.
