Offering the towing capability that only a V-8 can, the 2008 H3 Alpha broadens HUMMER’s range of versatile, do-anything and go-anywhere vehicles. HUMMER announced the H3 Alpha at the NY Motor Show; it goes on sale this summer.
The H3 Alpha is the second member of HUMMER’s exclusive Alpha series, representing the pinnacle of performance, both off the road and on it. It comes with a new, 5.3L V-8 engine that delivers 295 horsepower (224 kW)* and 317 lb.-ft. of torque (438 Nm)*. It is partnered with a four-speed automatic transmission and enables a maximum towing capacity of 6,000 pounds (2,721 kg) – an increase of more than 33 percent over other H3 models
“H3 Alpha is, simply, the ultimate HUMMER H3,” said Martin Walsh, HUMMER general manager. “It delivers all of H3’s renowned off-road capability, but with enhanced performance that is suited to a variety of lifestyles.”
In addition to the V-8 engine, the H3 Alpha also includes the popular “Luxury” equipment package, the Chrome Appearance package, 16-inch chrome wheels, a 4.10 rear axle ratio and special Alpha identification, including a prominent tailgate badge, horn pad badge and embroidered front headrests with the “Alpha” insignia.
For customers who want a more accessorized appearance straight from the factory, the Alpha model can be combined with the H3 X content, which includes bright roof crossbows, chrome fuel door, a body-color grille and unique spare tire cover, tires, wheels and center cap, and a brush guard. Additionally, HUMMER Accessories offers an exclusive line of GM-designed, manufactured and validated accessories that are engineered and tested for no-compromises fit, finish and performance.
“Because HUMMER stands for more than just off-road performance, the H3 Alpha builds on the style and refinement of the H3 lineup and offers a unique, instantly recognizable statement on the road,” said Walsh. “In short, the H3 Alpha matches HUMMER’s off-road expectations with on-road attitude.”
Alpha – the ultimate HUMMER
HUMMER Alpha models represent the top in performance, capability and comfort. The H1 Alpha was the first of these ultimate HUMMERs, and like the H3 Alpha, it offered a more powerful engine as well as unique styling and comfort features.
The H3 is the newest model to carry the Alpha flag, and represents HUMMER’s first Alpha model engineered in conjunction with GM Performance Division.
Award-winning interior and safety enhancements
The H3 Alpha shares the same widely admired interior as all H3 models, including detail revisions and enhancements that have been implemented across the lineup. New child safety locks for the rear doors and easier-to-use power window switches were introduced during the ’07 model year and reflect customers’ input.
“Details matter, and our customers told us these details were particularly important, so we updated the H3 lineup to address them,” said Walsh.
Also new for the H3 Alpha and the entire 2008 H3 lineup are standard head curtain side air bags; they were previously optional. Additional standard safety features now found on all H3 models include:
HUMMER’s Rear Vision system and a navigation system are available. The Rear Vision system uses a camera mounted near the rear bumper to provide a view of objects directly behind the vehicle. Also, the safety and security of OnStar is standard, and its new Turn-By-Turn Navigation feature is available.
Powertrain details
The H3 Alpha’s 5.3L engine is a powerful and efficient member of GM’s legendary small-block V-8 family. It is rated at 295 horsepower (224 kW)* and 317 lb.-ft. of torque (438 Nm)*; and is similar to the small-block V-8 found in the Chevy Silverado, which was named the 2007 Truck of the Year at the North American International Auto Show.
“For jobs such as towing personal watercraft up a mountain to the lake, the small-block V-8’s torque performs with effortless ease and little impact on fuel mileage,” said Christopher Meagher, assistant chief engineer of small-block V-8 truck engines. “The 5.3L engine greatly broadens the H3’s towing capability.”
Effortless highway driving also is an attribute of the 5.3L V-8, which enables 0-60 mph performance of approximately eight seconds.
“All of the powertrain options in the H3 lineup deliver performance suited to different driving styles and needs,” said Meagher. “But when it comes to certain tasks such as towing, there is sometimes no substitute for a V-8 engine.”
An aluminum cylinder block is used with the H3 Alpha’s engine. It helps reduce overall mass and maintains a more desirable front-to-rear weight balance. Like all of GM’s small-block V-8 engines, highlights include:
GM’s small-block V-8 engines are engineered to meet today’s more stringent emissions standards. In fact, the H3 Alpha’s V-8 engine beats the deadline for new, U.S. federal emissions standards by a year. And compared to truck engines of a decade ago, the small-block engine family is approximately 90 percent cleaner. Cast iron exhaust manifolds matched with four close-coupled catalytic converters help reduce cold-start emissions, which is the largest source of vehicle emissions.

At the same time, the V50 approaches the new V-range and the all-new V70 without compromising on its original compact and sporty attributes.”When it comes to the exterior, we’re aiming for increased differentiation between the two models. The interior refinements have focused on liberating smart storage space,” says Volvo Cars Design Director Steve Mattin.
