General Motors

Heard of GM's Hummer 02 concept?

GM designers used a far-future Hummer design to win a competition at the L.A. Auto Show to design an environmentally sustainable vehicle of the future.

What you're looking at will likely never be built - it's a 2D design only. Not even a small scale mockup has been made.

It boasts a jet engine. It's very cool. And it's real, but you can't buy it.

Entertainer and American car buff Jay Leno inspired GM (yes, stodgy General Motors) to build a jet powered bio diesel supercar. And they did. The car was introduced last night at the Specialty Equipment Market Association (SEMA) show in Las Vegas.
