Subscribe – http://goo.gl/wpc2Q1 Every industry has its mavericks and the car industry is no exception. This car was created by car designer Jim Router, and takes its inspiration from a surprising source, the Lockheed Martin F-117A stealth bomber. It disregards standard design concepts and follows the angular shape of a plane, made up of a series of carefully angled panels. The jet feel continues inside the car, the driver sits in the centre of the cockpit, and even the instruments are based on the F-117 bomber. Router’s stealth car may look eccentric, but he also helped design the Lotus Elan, and the world’s most expensive car, the F1 McLaren. Clip from the documentary “Extreme Machines – Car Crazy”.
