This is obviously no gadget (or technically is albeit at current a potentially very big and expensive none existent one) but I just had to feature it for its proposed concept with the technologies they reckon it will use. Its not often the words sports car and good fuel economy can be motioned in the same sentence in the real world if at all. As far as I'm aware it doesn't actually exist except as a computer simulation. I just couldn't get over how beautiful it looked as a sports car concept. More drool worthy concept images and a video peek into it all just below.
