2006 HUMMER H1 Alpha
The new 2006 H1 Alpha, featuring GM’s award-winning Duramax 6600 diesel
engine, is the first in HUMMER’s new performance series and represents the
single greatest advance in the 14-year history of the original HUMMER.
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.

2006 H1 Alpha: The Original HUMMER’s Legendary Performance Reaches a New Level
|
Source: GM | Published: Tue Sep 27, 2005 |
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.
HUMMER Alpha Performance:
Best-Ever H1
The Duramax 6600 delivers 300 horsepower (223.5 kW) at 3,000
rpm, a 46-percent increase over previous H1s equipped with the 6.5L Optimizer
Turbo-Diesel. Peak torque is a massive 520 lb-ft (719 Nm) at 1,500
rpm, an 18-percent increase.
The added power enhances the vehicle’s already-extreme off-road crawling and
climbing capability. On the road, the new powertrain offers smoother, quieter
and more comfortable operation, with better acceleration. Zero-to-60
acceleration improves by three seconds to 13.5 seconds.
In addition, preliminary testing indicates significantly improved fuel economy
(mileage estimates not yet available). A revised fuel system also increases
capacity of the H1’s two on-board tanks to 51.5 gallons (195L), 9.5 gallons
(36L) more than previous H1s. The increased tank capacity combines with the
efficiency of the Duramax to increase cruising range from 400 miles (643 km) to
an estimated 570 miles (917 km) between fill-ups.
The five-speed automatic Allison 1000 transmission is extremely stout and
durable, as it also is used in medium- and heavy-duty commercial trucks. It
features a Tow/Haul mode that adjusts shift patterns for optimal performance
when the vehicle is towing or carrying heavy loads. The Allison unit aids the H1
in severe maneuvers with features such as improved drivetrain braking and a
crawl ratio of 45:1, an increase of 22 percent. ...HUMMER H1 Alpha: Page 2
