Any clue what the energy provided to the wheels is for electric cars like a Tesla? I'm wonder what the energy loss is for electric cars from stored form to actual power at the wheel.
- plorkyeran 13y agoThe Tesla Roadster was 88% efficient. I don't remember the exact value for the Model S, but it's in the same general range. This huge difference is the main thing that makes electric cars viable.
