Jay Leno's Ecojet mobile.
The world's biggest car nut has done it again. Jay Leno has found a new way to make his already fascinating life with cars even more interesting, and it comes in the form of the Ecojet. The Ecojet is a turbine-engined car that runs on both jet fuel and bio-diesel, and has been built in collaboration with GM. Lucky for us, Jay has made a great video of the build process of his car, and takes it out for a "little spin" (by which we mean a drag race with a private jet).
