Biodiesel Hummer

The world's first Hummer H2 with a Duramax LBZ engine and Allison 1000 transmission to run on biodiesel. This Hummer achieves 500+ horsepower and over 20 miles per gallon. We're increasing that to 700+ horsepower and 30+ mpg by adding more of our technologies! All this, without using a drop of petroleum fuel. (Although it runs great on petroleum diesel, biodiesel or any combination of these two fuels.)
