The H1 Alpha is the first in Hummer’s new performance series and represents the single greatest advance in the 14-year history of the original Hummer.
As was the case for previous H1 models, the H1 Alpha is offered in both Open Top and Wagon models.
The 6.6-liter V8 engine delivers 300 horsepower at 3000 rpm. Peak torque is a massive 520 lb.-ft. at 1500 rpm.
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.
The five-speed automatic 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 H1 Alpha also has greater towing capacity. Gross Combined Weight Rating (the sum of vehicle, maximum cargo and towing capacities) increases by 2,000 pounds, to 17,300 pounds
