2006 Hummer H1 Alpha

The H1 Alpha delivers more power, more torque, and enhanced on- and off-road capability, with significantly improved fuel economy. It represents HUMMER performance taken to its ultimate extension.

As was the case for previous H1 models, the 2006 H1 Alpha is offered in both Open Top and Wagon models. The Duramax 6600 replaces the previous 6.5L Optimizer Turbo-Diesel, which continues as the power plant for the military HUMVEE. All commercial H1s produced for the 2006 model year will be H1 Alpha models.
