- Tesla patented a fan system to increase an EV's downforce.
- It comes two weeks before the event revealing the Tesla Roadster.
- It isn't clear whether this is going into a production car, but it could help the Roadster fulfill some of its wildest promises.
With the Tesla Roadster event just a couple of weeks away, the automaker has patented a design for a car that uses fans to improve downforce and reduce drag. Coincidence? It very well could be. Car companies patent things all the time, and it doesn't mean these features are actually going into production.
