The SWINCAR.  It’s an all-electric off-road vehicle with a very, VERY flexible chassis (and ya’ll can just get your minds out of the gutter right now, it ain’t that kind of flexible chassis).

The key thing to note is the lack of any axles.  Each wheel has it’s own electric motor, which allows for a low slung design and a wide range of motion for the suspension arms.  Some years back I had drawn up some initial designs for something similar, but with a higher center of gravity.  Alas, no money, and battery technology wasn’t quite there yet, so it was all just on paper.
