I can believe it. 20 hp is enough if the car is slippery and light.

If just 80 hp can propel a 2-ton AUV with the aerodynamics of a brick to 140 km/h, I suppose just 20 can do the same for something weighing less than 1/4 as much and with much much less drag.

Wonder how much it'll cost? Looks like a good alternative to a motorbike.
