The Eco-Jet is a hyper car developed in joint by GM and Jay Leno. This car was developed in mind to the need for a flying car. Jay came to General Motors and presented his idea. They thought he was crazy so he built it himself in his own garage. This car is capable of speeds of over 600mph when is car mode. When engaged in jet it can reach near supersonic speeds but will run out of fuel in approximately 2 hours and 40 minutes. Not much is known about this vehicle other than it is in Jay's garage and he occasionally launches it off a ramp he built in his backyard.
