I don't know if there is a more suitable thread to suggest some active areodynamics, but here are my suggestions for active and passive aero ideas:
1. Variable cooling management for cooling of the engine and brakes, as demonstrated in this advertisement from Mercedes-Benz:

3. The ability to remove exterior side mirrors and replace them for cameras, as shown for the Tesla Model X and the Volkwagen XL1?

5. Is the shape of the windscreen and other details from the car bodies going to affect aerodynamics beside the basic aero drag from a car body?
