H3 ALPHA

INTRODUCING THE NEW H3 ALPHA. Performance bred, the H3 Alpha is quite simply the ultimate H3. Part of the elite HUMMER "Performance Series," the H3 Alpha excels in both off-road capability and interior comfort. More horsepower, more torque, more towing capacity, more cabin amenities. Top to bottom, the perfect combination of performance, power, capability and luxury in a midsize SUV.
ENGINE
At the heart of the H3 Alpha is a powerful 5.3L V8 engine that delivers an impressive 300 horsepower and 320 lb-ft of torque.
With the Alpha, our engineers didn’t merely shoehorn the V8 into the H3’s engine compartment; they went back to the drawing board and made a number of significant improvements that enhance performance.
To begin, the front section of the frame and the engine compartment of the H3 were modified to fit the new engine while a special oil pan was designed to ensure constant oil pressure when driving on steep grades. A cast-iron front differential case replaced the old aluminum one to better handle the torque output, and an improved steering system enhances on-road feel and off-road reliability. New engine mounts, a thicker front prop shaft, higher torsion-bar rates to support the increased mass, and specific shock valving are unique to the V8 and ensures outstanding on- and off-road handling.
Engineered to meet stringent emissions standards, the H3 Alpha’s V8 engine is not just cleaner but beats the deadline for the new U.S. federal emissions standards by a year.

BADGE
Introduced as a high performance line, the HUMMER Alpha series is built around one central motivation. Passion. In 2006, driven by a passion for engineering, we introduced the H1 Alpha. A vehicle so immensely capable, it surpassed anything that came before it. In 2008, we did it again. The H3 Alpha delivers a driving experience beyond compare. With the most horsepower, torque, pulling power and luxury of any H3 yet produced, this is not only a vehicle that sets you apart, but truly sets you free. And the "Alpha" badge emblazoned on the tailgate signals your departure from the ordinary and your arrival into a whole new class.

ONSTAR
DRIVING CONFIDENCE
See how OnStar is giving drivers greater confidence on the road.
Standard for 1-year on HUMMER H3 Alpha is the state-of-the-art OnStar system. First and foremost, OnStar means safety. In an emergency, such as vehicle collision, your OnStar system can automatically notify your OnStar Advisor and provide your Alpha’s exact location. The OnStar Advisor can attempt to contact you to inquire whether you need assistance. Also, the OnStar Advisor can notify emergency services and send help to you.*
But, we hope that never happens. So we made sure OnStar would still be useful to you in a multitude of other ways. For example, if you ever make the unfortunate mistake of locking your keys inside your HUMMER, you can call the OnStar center and an Advisor can send a signal to unlock your doors remotely.† If your "check engine" light ever illuminates, or you suspect trouble, at the touch of a button on your Alpha’s rear-view mirror, your OnStar Advisor can help by running a diagnostic check of your engine, even while you’re still driving. Or, if you ever forget where you parked your Alpha, you can alert OnStar to activate your horn and lights to easily locate your truck.
In the event of theft, OnStar can also attempt to pinpoint your Alpha’s exact location in real time, aiding greatly in vehicle recovery.† Also, OnStar can help you stay connected with OnStar Hands-Free Calling, which allows you to make and receive hands-free calls in your Alpha while keeping your hands on the wheel and your eyes on the road.‡
AND WITH YOUR NEW H3 ALPHA YOU WILL RECEIVE THE ONSTAR SAFE AND SOUND SERVICE PLAN.
For more information call 1.888.4.ONSTAR (1.888.466.7827) or visit www.onstar.com for system limitations and details.
*OnStar acts as a link to emergency service providers. Visit www.onstar.com or call 1.888.4.ONSTAR (1.888.466.7827) for system limitations and details.
†Success varies with conditions.
‡OnStar Hands-Free Calling requires a Hands-Free Calling enabled vehicle, existing OnStar service contract and prepaid minutes or enrollment in a shared minutes plan. Not available in certain markets. Calls may be made in U.S. and Canada only.
XM RADIO
XM Radio* comes standard with thee trial months of service on every H3 Alpha.

TOWING
The 5.3L V8 when partnered with the Alpha’s Hydra-Matic 4L60 electronically controlled four-speed automatic transmission enables a maximum towing capacity of 6,000 pounds. So if you decide to tow your boat up the mountain to the lake, the H3 Alpha performs with utmost ease.
ON THE OUTSIDE
PROTECTION
With all this off-road capability, exterior protection is obviously imperative. To that end, the H3 Alpha boasts underbody protection that runs the entire length of the vehicle beginning with the thick, solid aluminum, front skid plate. This shield helps protect the frame and front suspension components from rock strikes and other hard hits. Also standard are three high-strength steel skid plates to help protect the oil pan, fuel tank and the transfer case.
An available Underbody Protection Package features two skid plates, providing enhanced protection for the transfer case and the transmission oil pan as well.
Also available is the full-body Rocker Panel Protection designed to help protect the sides of the vehicle from even the meanest off-road threats.
With all these features, the H3 Alpha not only makes sure you can get your truck out into the rough country, but also makes sure you have all the protection required to get back.

OFF-ROAD CAPABLE
The H3 Alpha’s large tires, wide stance, and short front and rear overhangs combine not only to carve a distinctly HUMMER silhouette, but also to provide stability, outstanding ground clearance and enhanced rock-climbing capability. The skidplate provides vital underbody protection while off-roading. The large tires also enhance traction both on- and off-road.
In short, the H3 Alpha is capable of…
GROUND CLEARANCE
Standard 32" tires: 8.5 in.
Optional 33" tires: 9.1 in.
Vertical scaling height: 16 in.
Side slope capability: 40%
Grade capability: 60%

ON THE INSIDE
SEATING
The H3 Alpha features standard leather-appointed plush bucket seating, that comfortably houses 5 adults. The front seat headrests are embroidered with the premium "Alpha" logo as a finishing touch to double-stitched "French" seams throughout the rest of the interior. The front and back row seats all come with dual density foam and soft bolsters to provide additional comfort and help provide support during severe off-road maneuvers. In addition, the back row seats have a 60/40 split that can be folded down to create 56.4 cubic feet of cargo space.*
The leather-appointed seating comes in Ebony with Pewter piping, Light Cashmere with Ebony piping or Ebony with Morocco-toned seat inserts and piping.
*Cargo and load capacity are limited by weight and distribution.
INTERIOR
The H3 Alpha was designed to be as intuitive as possible. To act as an extension of your body and a reinforcement of your instincts. The cockpit controls and features are a natural progression from the slick, streamlined interface of the legendary H1. From the rotary control switches to the individual gauge bezels, to the soft touch caps on the control switches, you’ll notice everything is logical, organized, easy to use and accessible.
In addition, you’ll find a host of subtler features that enhance your interior experience. Like the five standard assist handles that make entry easier and offer support in severe off-road terrain. The unique brushed finish on the driver information center adds a premium feel while the leather-appointed seating, automatic gear controls and chrome door handles combine to create class and richness.
The idea is workmanship. Intense dedication has brought an iconic HUMMER design full circle with a rich, classy and sophisticated interior. The kind of luxury that easily puts us in the same league as other, more expensive vehicles. This is an Alpha, after all.
STEREO/NAVIGATION
The H3 Alpha comes with an ETR AM/FM stereo with in-dash 6-disc CD changer. A larger (single-line, 12-character) text display features a performance-enhanced, premium, 7-speaker Monsoon® sound system delivering 200 amplified watts.
The optional DVD-based Navigation Radio instantly maps routes with 2D and 3D graphics.* View the maps on a 6.5-inch diagonal LCD touch screen. Once en route, drivers hear verbal instructions to keep them on course. The navigation system comes with separate DVD and CD slots as well as XM Radio† with three months of trial service.

H3 ALPHA OFF-ROAD
THE HUMMER REPUTATION FOR OFF-ROAD CAPABILITY IS LEGENDARY. With the H3 Alpha, we’re making our latest claim to the throne. This is the vehicle that gets you up the mountain, out of the ditch, over the logs, into the wilderness and makes it seem effortless. Here’s why.
V8 ENGINE
At the heart of the H3 Alpha is a powerful new 5.3L V8 engine delivering an impressive 300 horsepower and 320 lb-ft of torque. In addition, we have painstakingly engineered a host of platform enhancements to properly accommodate the V8’s increased size, weight, and power.
A cast-iron front differential case replaced the old aluminum one to better handle the torque output, and an improved steering system enhances on-road feel and off-road reliability. New engine mounts, a thicker front prop shaft, higher torsion-bar rates to support the increased mass, and specific shock valving are unique to the V8, ensuring outstanding on- and off-road handling. And with up to 6,000 lb. in towing capacity, you can tow your trailer through the snow, uphill, both ways without even breaking a sweat.
POWERTRAIN
In a well-built machine, power and control go hand in hand. Built around an advanced, fully integrated powertrain system, the H3 Alpha is a full time 4WD vehicle. The Alpha’s 5.3L V8 engine, when partnered with the Hydra-Matic 4L60 electronically controlled four-speed automatic transmission enables a maximum towing capacity of 6,000 pounds. And with the powertrain integrated, 2-speed, electronically controlled, full-time 4WD system, the Alpha can generate more precise throttle and more horsepower custom fit to the turf of your choice. This, coupled with the full-function, single wheel traction control, allows the Alpha to marry powerful off-road capability with outstanding fuel efficiency.*
*EPA estimated mpg 16 highway/13 city.
HORSEPOWER
Horsepower is muscle – plain and simple. And the H3 Alpha packs a 300 horsepower engine with 320 lb-ft of torque. This makes a wide variety of terrain yours for the taking.
And with the 2-speed, electronically controlled, full-time 4WD system, you can choose between a range of high for on-road and low for off-road. This way, the H3 Alpha gives you more precise throttle and more horsepower at slower speeds for the times when you need it most.
