These awesome General Motors Gravity cars were designed and made for the Extreme Gravity Competition in Irvine, California. They're crafted from the same materials as Formula One race cars.
The General Motors Extreme Gravity cars can reach screaming-fast speeds of up to 70 mph. The models shown here were conceived and created at the General Motors 5350 Design Studio. With price tags of up to $30,000 each, these motorless downhill racing vehicles are definitely a step up from the soapbox derby racers that inspired them.
