Tesla patent hints at downforce fans for the new Roadster

A newly surfaced Tesla patent describes four powered fans in the rear diffuser that pull air from under the car to generate downforce independent of speed. The drawings show a Model S, but with that model discontinued, the tech is widely linked to the new Roadster, expected to be shown on October 15.
