Downforce is more than the wing. You see those giant diffusers in the back? Those work as venturi tunnels, creating a sucking force, sticking the car down.
As a matter of fact, F1 cars in the 70s-80s were using venturi tunnels that extended the entire length of the vehicle. This is impractical in a modern gasoline-powered car.
Theu were even getting so good with their aerodynamics that they were rumoured to be generating more downforce with ground effects than from wings.
In an electric car, you could do what they were doing back then.
- neom 9y agoI guess I'll be eating my hat then. I'm pretty amazed that you'll be able to keep it planted that fast around corners, but if you can, this will be an incredibly fun (or maybe very boring!) car to drive.

- wallace_f 9y agoJust pretend, the same way they do with the claims about the GTR's ~0-degree wing, and most all aero claims on street-legal cars. Aero at street legal speeds is basically worthless and range-destroying. Many supercars don't have more aero than the Roadster, just go look at them, they usually either have no wing, like the Lambo Huracan, or a wing with virtually no angle of attack.
