Note that No, even best supercapacitors are a long way to go from reasonably good electrochemical energy sources. But you can recharge and discharge them very quickly, and they take lots more of cycles than the best battery. Ideal for absorbing the braking energy and turn them into smoking tires few moments or minutes afterwards. > the battery packs are fully swapped out for recharging after each run > anyway, just like a gas dragster is refueled, so this wouldnt be cheating. > 200 MPH should be no problem. I don't see any reason why EVs shouldn't dominate dragster runs. The traction is the limiting factor, not motor power. You can basically put the motors into wheelhubs mounted on a composite frame, and dump juice into them until they melt, which will be some 100 sec downstream. Plenty of time to smoke anything. Of course, it doesn't roar, and spew smokage, so it won't happen.
