This is probably the most unique EV projects that I've seen out there. I can't help to be really impressed by their ambition. Personally I'm really hoping this projects succeeds. Skip to ~8:20 for the Tesla portion.
The remaining question here, which they seem to avoid mentioning, is how the controller/inverter that supposedly works with a Tesla motor is going to perform for them. They should have no problem fitting the Tesla axle into that car and also fitting a few Tesla battery segments as well but stay tuned for when they finally step on the accelerator.
