What I would give to be Jay Leno right now.  Not just because hes a famous celebrity but because when he talks to the GM Vice President of design Ed Welburn about creating a mid-engine supercar, not only does he listen, he actually produces the car.  "EcoJet's esthetics were driven by aeronautical and jet-age influences," said Welburn. "It's a purpose-driven design that conveys power, capability and even danger, with a hint of Cadillac's sophisticated design vocabulary."  The 650-horsepower (400 lb-ft of torque) Leno original is powered by a Honeywell LT-101 turbine engine that runs on bio-diesel fuel. The engine sits in a modified Corvette Z06 hydroformed aluminum frame with aluminum and magnesium structural and chassis components.
