I want my hovercar too, dammit

Some British engineering firm has built a hybrid mini that gets 80 mpg, does 0-60 in 4.5 seconds, and has a radius of 800 miles. There is no doubt some hyperbole in this, and I suspect there are some unsolved problems (I wonder about the unsprung weight of those wheel-motors), but still, very impressive.

This makes me angry. If a shop like this can do it, why can’t the big guys? Shoot, I’d settle for a car with those specs that did 0-60 in 5.5 seconds.
