Silbervogel Gravity Car Has No Muscle, Still Makes the Mark

The Silbervogel Gravity Car concept, by Jakob Hirzel from the Pforzheim University Of Applied Sciences in Germany, has no engine, but still wants to grow up and be a real racing vehicle. The racer relies solely on, you guessed it, gravity to pick up speed. We're thinking the whole exempt engine thing is going to give the Gravity Car a little handicap in conventional races, but as a play thing, it would be pretty great. [Jakob Hirzel via Tuvie]
