A HUMMER H1 Alpha is truly like nothing else! Using the Original H1 as a base, our engineers set out to create a truck that could do even more and do it better. They succeded. We made improvements wherever the latest technological advances led us. New to the H1 Alpha, you'll find a Duramax engine, an Allision transmission and a highly refined interior. The new H1 Alpha has more performance, torque, pulling power and luxury, giving you one of the most unique driving experience in the world.
