When I read “electric fan car” I thought the fans would be producing forward thrust to accelerate the car, not downforce. This raises the question—would it be more effective to accelerate the car this way (probably less efficient, even with huge aircraft style electric ducted fans) vs. putting the force through the wheels (limited by traction)?
- jackmott42 4y agowell it sucks to the ground AND blows that air out the back, though the thrust is negligible. The answer to your question though is no. It is much more efficient to push against the ground with the tire. In fact this sucking method is more efficient than a wing or other aerodynamic down-force devices. You might see the wing they have no go away at some point, as it was added to improve balance. Maybe they will figure out how to adjust that with the skirt or something.

In water it'd work, but then you've made a boat and the wheels are irrelevant. Boats have always been capable of faster acceleration in theory. Problem Child, for example, did 0 to above 250mph in about 3.5s.
