Electric car 3 times more efficient than a Prius Answered
OptaMotive is working on the E. Rex, an electric three-wheeler that goes 0-60 in under 5 seconds, is three times as efficient as a Prius, and has a range of 100 miles. The focus is on the driving experience, though, and there's barely enough room for the driver and passenger, much less a couple more friends or some groceries in the trunk. OptaMotive is predicting a top speed of 160 mph, but hasn't had a chance to test that out yet.
Right now the car is in the testing phase so there's little chance of getting to drive it any time soon. If it does go on sale it's likely to cost over $50k, making the Prius a hell of a deal in comparison.
