New H1 Alpha Hummer revealed
Anaheim, Calif. – The 2006 H1 Alpha, featuring GM’s Duramax 6600 diesel engine, arrives in dealerships in early 2005. The H1 Alpha, revealed today at the California International Auto Show, delivers more power, more torque, and enhanced on- and off-road capability, with significantly improved fuel economy. GM’s award-winning Duramax 6600 (6.6-liter) turbo-diesel engine and Allison 1000 five-speed automatic transmission give the H1 Alpha performance improvements and add to the H1’s legendary off-road capabilities.

H1 Alpha is the first in Hummer’s new performance series. “Alpha represents Hummer performance taken to its ultimate extension,” said Susan Docherty, Hummer general manager. “That means improving Hummer’s already-unmatched off-road capability, along with enhancements to fuel efficiency and driving comfort on the road. As the original Hummer, the H1 is the perfect vehicle to mark the start of the Alpha series.”
As was the case for previous H1s, the 2006 H1 Alpha will be offered in both Open Top and Wagon models. The Duramax 6600 replaces the previous 6.5-liter Optimizer Turbo-Diesel, which will continue on as the power plant for the military HUMVEE, the vehicle on which the H1 is based. All commercial H1s produced for the 2006 model year will be H1 Alpha models. H1s used for fleet sales will use the Optimizer engine.
The Duramax 6600 delivers 300 horsepower at 3000 rpm, a 46 percent increase over previous H1s equipped with the 6.5-liter Optimizer Turbo-Diesel. Peak torque is a massive 520 lb.-ft. at 1500 rpm, an increase of 18 percent.
