Hummer H3T Alpha, 2009
Hummer H3T Alpha, 2009
The Hummer is bringing its unmistakable style and unmatched capability to the truck market with the 2009 H3T. It is based on the architecture of the popular H3, but features a five-passenger crew cab and a separate five-foot-long (1.5 meters) bed.
The Hummer H3T is bigger than a midsize truck and smaller than a full-size truck, creating its own niche in the market. It also is infused with the attributes expected of a HUMMER, including exceptional off-road capability and a premium interior that is as functional as it is comfortable.
Design
Like all HUMMER models, The Hummer H3T has a purposeful design. Its consistent and iconic styling cues include a wide, aggressive stance; a low roofline and high beltline; and large, off-road tires. The wide, seven-slot grille and round headlamps mounted in square housings are signature HUMMER design elements.
The crew cab body shares H3 styling and components from the B-pillar forward, while the rear section of the cab and the separate bed are unique to The Hummer H3T. The five-foot bed is similar in design and function to GM's recently redesigned full-size trucks, including an easily removable tailgate and provisions for a bed-rail accessory system. A full-size spare tire is mounted beneath the bed.
The bed is sized to carry a wide range of popular outdoor necessities, from hauling motocross bikes to Baja, a quad to camp, or backcountry gear to the trailhead. One of the industry's largest portfolios of accessories complements The Hummer H3T's bed, offering different cargo management options to suit all of those lifestyle interests.
Accessories
One of the industry's broadest portfolios of vehicle accessories has been developed for The Hummer H3T. Centered on active lifestyles, items such as removable and lockable bed-mounted storage boxes; an adjustable bike chock that can be used to help secure mountain bikes or motorcycles; and a bed extender make full use of the standard bed-rail cargo management system. A range of additional accessories that improves off-road capabilities, provides passenger entertainment and enhances exterior styling is also available. There are more than 75 HUMMER Genuine Accessories offered.
In addition to the factory-developed accessory portfolio, HUMMER has partnered with top automotive aftermarket companies to develop more than 50 Officially Licensed HUMMER Accessories - a first for the brand. A variety of exterior enhancements, such as a Slant Back Bed Cover, hard tonneau covers and a winch are offered, along with cargo management solutions such as the BedSlide and bed divider, offering countless possibilities to personalize The Hummer H3T.
Interior
The Hummer H3T's crew cab cabin offers seating for five adults, with a 60/40-split rear bench seat that folds flat for increased cargo-carrying options. The cabin's layout is essentially identical to the acclaimed H3 SUV, with premium materials and attention to detail that give the vehicle a functional yet refined aesthetic.
Standard amenities also include air conditioning, power locks, power windows and remote keyless entry. An AM/FM radio with CD is standard and a premium Monsoon audio system is available. XM Satellite Radio also is standard and includes three months of trial service.
Powertrain
Standard in The Hummer H3T is the Vortec 3.7L I-5 with dual overhead cams and variable valve timing. This inline five-cylinder engine offers an excellent combination of power and efficiency, delivering 242 horsepower (180 kW) at 5600 rpm* and 242 lb.-ft. of torque (328 Nm) at 4600 rpm. It is backed by a five-speed manual transmission or an available four-speed, electronically controlled automatic.
The Hummer H3T Alpha's 5.3L engine is a powerful and efficient member of GM's legendary small-block V-8 family. It is rated at 300 horsepower (224 kW)* and 320 lb.-ft. of torque (434 Nm).* 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.
A Hydra-Matic 4L60 electronically controlled four-speed automatic transmission is paired with the 5.3L engine. Flat towing is enabled on all H3 and H3T models.
Chassis
The Hummer H3T's frame and suspension system are based on a stretched version of the H3 SUV's chassis and suspension - the same race-proven design found on Baja 1000-winning stock-class race trucks. The wheelbase measures 134.2 inches (3,409 mm) - 22 inches (86 mm) longer than the H3 SUV.
A ladder-type frame is the truck's foundation and it has a modular, three-piece design that incorporates fully boxed components for outstanding strength and stiffness. An independent SLA torsion bar front suspension and multileaf Hotchkiss-type rear suspension are used.
There are two suspension packages:
* Z85 Heavy-Duty Handling and Trailering - This standard suspension delivers an excellent balance of on-highway comfort and off-road capability. It includes 32-inch all-terrain tires mounted on 16-inch, smoke-color steel wheels, specially tuned heavy-duty shocks and either a 4.56-ratio (3.7L) or 4.10-ratio (5.3L) rear axle.
* Off-Road Adventure - Designed for more aggressive off-road performance, this optional suspension package includes taller, 33-inch tires, specifically tuned shocks, locking front and rear differentials, 4.03:1 low-range gearing in the transfer case and industry-leading crawl ratios of either 68.9 with the manual transmission or 56.2 with the automatic.
To support the torque output of the 5.3L V-8, The Hummer H3T Alpha's front differential case is made of cast iron; other models feature an aluminum case. V-8-powered vehicles also receive higher torsion bar rates to support the increased mass and specific shock valving. The chassis and suspensions were validated in real-world testing on off-road trails in Moab, Utah; the Rubicon Trail in California, and other challenging off-road venues.
Off-road capability
The Hummer H3T lives up to HUMMER's legendary off-road reputation, with best-in-class extreme off-road capability. Highlights:
* Ability to climb a 60-percent grade and traverse a 40-percent side slope
* Exceptional 10.2-inch (285 mm) ground clearance (with 33-inch tires)
* 38.7-degree approach angle and 30.1-degree departure angle (with 33-inch tires)
* Segment-first available front- and rear-locking differentials
* Standard HUMMER Hill Hold Assist for improved hill ascension

Hummer HX Concept, 2008
Hummer HX Concept, 2008
With its unmistakable HUMMER design and a compact, go-anywhere driving ethic, the HUMMER HX concept challenges the hierarchy of the trail. HUMMER displayed the nimble.
More compact than a HUMMER H3 - 81 inches (2,057 mm) wide, with a 103-inch wheelbase (2,616-mm) - the HX concept is an open-air, two-door off-road vehicle that packs the off-road acumen for which HUMMER has become legendary, along with an easily convertible body that acclimates to varied trail conditions, cargo needs or passenger whims. Its design is based on the ideas developed by a trio of young designers who are new to the HUMMER studio.
The HX was shown with a slant-back configuration, wearing a desert-inspired matte olive paint scheme, at the North American International Auto Show. Additional convertible features:
- Removable doors - easily removable pins in the exposed hinges allow the doors to be removed quickly - an appreciated feature of many serious off-roaders
- Removable fender flares - attached with quarter-turn quick-release fasteners, the composite fender flares can be quickly removed for additional trail/rock clearance, or if the flare is damaged during off-road driving
The design of the HX was driven by input from three young designers who were new to GM and the HUMMER design studio. As part of their "initiation," they were charged with developing concept drawings for a smaller, youthful HUMMER and the HX is a direct result of their creativity. The HX concept is based on one of the designers' original illustrations, but incorporates the best ideas and elements from the other designs.
On the exterior, the lightweight theme is evidenced in the appearance of exposed, billet aluminum suspension components that feature CNC-machined lightening relieves, as well as clean, unadorned bodywork and minimal trim. The lightweight theme is taken to its extreme when the roof panels, roof assembly, fender flares and doors are removed.
Classic HUMMER design cues make the HX instantly recognizable, including the round headlamps located in square housings, an upright windshield profile, minimal overhangs, hood vents and prominent air intakes. The air intakes are functional and feed a V-6 engine beneath the hood, while the hood vents are active - they articulate to allow hot underhood air to escape.
Aeronautically inspired interior
From aircraft-inspired seats to integrated, off-road-ready tools, the HUMMER HX's interior has a beauty that lies in its purposeful intent. It was inspired by the functional and lightweight elements found in aircraft.
Reinforcing the stripped-to-the-essence feel, the exterior's matte olive color carries over onto the interior's largely sheet metal-covered panels. The color is accented with pressed or extruded aluminum components, such as the handles, switches and other necessary parts.
Furthering the aeronautical influence is the instrument panel, which uses an exposed, extruded aluminum cross-vehicle beam as its foundation. On the beam, the instrument cluster and other vital controls are mounted; and it also features a unique, removal top cover that provides significant storage capability.
Seating and console details
Like aircraft seats, the HX's seats are constructed on a lightweight framework with minimal components that feature lightening holes and strength-enhancing cross braces or triangulations. They are mounted on exposed, aircraft-style tracks and trimmed with a weather-resistant neoprene material.
The HX seats four, with a pair of bucket-type seats in the second row. The rear seats mimic the front seats' design and can be removed to generate more cargo room. All the seats feature a four-point, racing-style safety harness.
The inner seat track on both front seats is located beneath the outer edges of a prominent center console. The console offers exceptional storage capability and houses a unique shifter that mounts low and out of the way when the vehicle is parked - also hiding from sight the engine starter button. It has a spring-loaded cover that pops up when the driver is ready to select a gear.
The console houses a resting place for phones, MP3 player and iPods or iPhones. In fact, there is no conventional radio in the HX, only integrated speakers. Passengers plug in an iPod, or similar device, to a USB connector to play music in the HX.
Gauges and tools
The "cut-off circles" motif of the exterior is seen even more so on the HX's interior, as the gauge cluster, instrument panel vents and even the steering wheel carry the design element.
A three-element gauge cluster - each of the three instrument "pods" carries the cut-off circle design - delivers crucial driver information in either a highway or off-road mode. This conceptual reconfigurable gauge layout uses LCD screens with multiple layouts, including a navigation system. The nav system features GPS and compass information; and is designed to upload trail information before setting off on an excursion.
The center gauge pod houses a speedometer and tachometer, but changes to a wheel angle indicator when the transmission is in the low position. This off-road mode changeover from the highway mode gives the driver information that is more pertinent to the driver conditions. The trail view of a camera mounted in the rear-view mirror can be displayed on the instrument panel, too.
The off-road mode features of the instrument panel comprise the virtual tools of the HX, while others are mounted for physical use, including a folding shovel, flashlight and first-aid kit. They all carry the "clipped circle" design motif found throughout the vehicle.
Ready for rocks, trails and more
With its compact dimensions, almost no overhangs and grippy 35-inch tires, the HX is ready for all terrains. Like all HUMMER production models, the HX has sturdy, body-on-frame construction, onto which is mounted front and rear independent suspensions.
The front suspension features an electronic-disconnecting stabilizer bar for enhanced maneuverability when driving off road, and the rear suspension is located with Computer Numerical Controlled (CNC)-machined, billet trailing arms. Heavy-duty shocks with piggyback reservoirs were custom-made for the HX by renowned racing shock manufacturer Fox; one is mounted at each wheel position.
A full-time 4WD system pulls the HX over, through and around off-road obstacles. It transfers torque to the front and rear axles, each of which is equipped with a locking differential. The torque meets the trail via custom 35-inch-tall off-road tires that are mounted on a set of custom, bead-lock-style wheels that have a two-tone appearance; dark-painted wheel centers complemented by silver-anodized outer rims.
A complete underbody armor kit, including a front skid plate, powetrain protection and more, protects the HX from wayward rocks and other potentially damaging objects. A power-operated winch is located in the front bumper, and the HX has recovery hooks mounted on the front and rear bumpers, just in case its help is required for wrangling others out of unfortunate off-road situations.
Motivation for the HX comes from an E85 FlexFuel 3.6L SIDI V-6 that is backed by a six-speed automatic transmission. The transmission is teamed with the 4WD system to offer exceptional low-speed traction and crawling capability. Four-wheel-disc brakes provide confident stopping power.

Hummer H3 Alpha, 2008
Hummer H3 Alpha, 2008
<Click the picture to enlarge>
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
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.
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.

- StabiliTrak electronic stability control system
- Four-wheel antilock brakes with traction control
- Dual front air bags with Passenger Sensing System
- Tire pressure monitoring system
- Vehicle-to-vehicle crash compatibility
- LATCH rear child seat anchors
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.
Effortless highway driving also is an attribute of the 5.3L V-8, which enables 0-60 mph performance of approximately eight seconds.
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, the highlights:
- Deep-skirt cylinder block with cross-bolted main caps
- High-flow cylinder heads
- Electronic throttle control
- 58X ignition system
- E67 32-bit controller
- Polymer-coated pistons with full-floating wrist pins
- Returnless fuel system
- Lightweight valvetrain
- Steel camshaft
- Low-restriction air intake system
A Hydra-Matic 4L60 electronically controlled four-speed automatic transmission is paired with the H3 Alpha's V-8 engine. And, as with all H3 models, flat-towing is enabled.
New V-8 drives vehicle-wide enhancements
HUMMER H3 and GM Performance Division engineers did more than simply shoehorn a V-8 engine into the H3's engine compartment. Accommodating the new power plant necessitated the execution of a seemingly endless number of technical details - many of which have been implemented across the entire H3 lineup.
The H3's frame was modified to accept the V-8 engine, and a special oil pan was designed to ensure constant oil pressure when driving on steep grades - a hallmark of HUMMER's off-road capability. Also, the engine compartment front of dash was modified to accommodate the V-8, and a new steering system is used on all H3 models to deliver better on-center feel and even more improved off-road reliability.
To support the torque output of the powerful V-8, the H3 Alpha's front differential case is made of cast iron; other models feature an aluminum case. New engine mounts, higher torsion bar rates to support the increased mass, and specific shock valving also are unique to the V-8-powered model, ensuring it continues to deliver the unparalleled ride quality - both on- and off-road - that customers expect.
All of the chassis and suspension changes were validated in real-world testing on off-road trails in Moab, Utah, the Rubicon Trail and other challenging off-road venues.
A HUMMER by any measure
All H3 models pack HUMMER's trademark capability into a midsize package. Compared to the H2, the H3 is 16.9 inches (429 mm) shorter in length, six inches (152 mm) shorter in height and 6.5 inches (165 mm) narrower. Roughly the same length as a midsize family sedan, H3 comfortably navigates city traffic and fits nicely in parking garages.
The H3 lineup also delivers exceptional rock crawling and climbing performance; it was engineered for off-road leadership among midsize SUVs. The heart of this capability is its electronically controlled four-wheel-drive system and suspension tuning tailored for off-road performance. In addition, the H3 features standard underbody shielding, brake traction control, and an optional 4.03:1 transfer case with rear locking differential.
Among its off-road credentials, the H3 can ford 24-inch (610 mm) streams at a 5-mph pace, climb 16-inch (407 mm) vertical steps and rocks, make its way through deep sand and race easily over sandy surfaces.
H3's more maneuverable size provides advantages, such as a 37-foot turning circle that is about the same as a typical compact car, making easy work of parking lot maneuvers and tight turns when off-roading. The 9.1-inch (231 mm) ground clearance and maximum breakover angle of 25 degrees (with 33-inch tires) both make it possible to clear large obstacles in off-road driving. Serious off-road performance is also aided by the maximum approach angle of 39 degrees and maximum departure angle of 37 degrees. These approach and departure angles permit the H3 to drive into a hole and back out again, without getting hung up in the front or rear.

Hummer H2, 2008
Hummer H2, 2008
The heart of the '08 H2 is a new, 6.2L V-8 engine that uses variable valve timing technology to maximize performance and fuel efficiency. It is rated at 393 horsepower (293 kW) and 415 lb.-ft. of torque (574 Nm). The engine features lightweight materials, including an aluminum cylinder block, which helps reduce the vehicle's overall mass.
The 6.2L V-8's technologically advanced features also help it meet new federal emissions standards a year before mandatory implementation.
A new six-speed Hydra-Matic 6L80 RWD electronically controlled automatic transmission backs the 6.2L engine. The 6-speed automatic has a wide, 6.04:1 overall ratio - including two overdrive gears - that helps deliver an excellent balance of performance and fuel economy. Also, the 6L80 has a "tap up/tap down" capability that allows the driver to manually select upshifts and downshifts with a button on the column shifter.
The new powertrain combination helps the 2008 H2 and H2 SUT deliver an additional 1,500 pounds (680 kg) in towing capacity - an increase from 6,500 pounds (2,948 kg) to 8,000 pounds (3,629 kg). A host of additional powertrain revisions contributes to the H2's improved performance and efficiency:
The transfer case is improved in the '08 H2; it is stronger with improved performance. A new traction control system also is standard, which helps ensure sure-footed traction in most driving conditions.
Driving performance off the road or on is enhanced by a revised steering gear that has a quicker ratio and improved on-center returnability. The driving experience also is quieter and more refined, thanks to new, tuned air intake and exhaust systems.
Safety standard
Complementing the H2 lineup's performance and comfort changes are enhancements to the safety system. They include several new standard features:
The first application for a full-size GM truck or SUV - which detects emergency braking situations and maintains maximum brake pressure to help stop the vehicle more quickly and with more control. It is a standard feature on all H2 models. Also, the standard OnStar system now offers the optional Turn-By-Turn navigation system. Additional optional features that contribute to a safer driving experience include HUMMER's Rear Vision System - a rearview camera system - and a navigation system.
Exterior enhancements
All 2008 H2 models are distinguished from previous models with functional changes that maintain HUMMER's instantly recognizable design identify. The iconic, seven-slot grille features larger openings and the lower grille also is enlarged, accommodating the cooling needs of the more powerful 6.2L V-8 engines. The lower bumpers on '08 models are painted silver (previous models had black lower bumpers).
The soul of a HUMMER
While the '08 H2 is offered with a new powertrain and interior, its foundation remains the same: a fully welded ladder-type frame that features a modular, three-piece design incorporating a number of hydroformed components. This design delivers outstanding strength, stiffness and dimensional accuracy.
The H2 has short overhangs for radical approach and departure angles, and exceptional ground clearance for minimal impact on trails. Standard 17-inch wheels, heavy-duty independent front suspension and a five-link rear suspension provide superior handling, carrying and towing capability. The solid rear axle ensures durable sure-footedness, particularly in tight, off-road situations. Also standard is underbody protection and rocker protection. These elements help the H2 deliver on HUMMER's mantra of capability, including traveling through streams 24 inches (508 mm) deep, climbing 16-inch (406-mm) steps and rocks and paddling through deep sand or snow.
A new, four-channel anti-lock braking/traction control system (ABS/TCS) provides optimum control on slippery surfaces. In addition, the ABS can detect and adjust its braking capabilities to rough off-road surfaces like gravel and potholes. The TCS also includes the ability to gain traction through a single wheel, if necessary, and more wheel slip in a second traction control mode for sand and desert racing conditions.
H2 SUT - maximum utility and fun
Like the H2, the H2 SUT carries passengers and cargo, but does so with a twist: an open cargo bed enables convenient storage of larger items. When cargo requires more space, a 4-foot by 6-foot (122-cm by 244-cm) pickup bed can be created by powering the rear window into the Midgate, then folding forward the Midgate and rear seat. With four passengers on board, the bulkhead at the rear of the SUT's passenger compartment remains upright, still providing ample cargo-carrying capacity.
The 6.2L V-8's technologically advanced features also help it meet new federal emissions standards a year before mandatory implementation.
A new six-speed Hydra-Matic 6L80 RWD electronically controlled automatic transmission backs the 6.2L engine. The 6-speed automatic has a wide, 6.04:1 overall ratio - including two overdrive gears - that helps deliver an excellent balance of performance and fuel economy. Also, the 6L80 has a "tap up/tap down" capability that allows the driver to manually select upshifts and downshifts with a button on the column shifter.
The new powertrain combination helps the 2008 H2 and H2 SUT deliver an additional 1,500 pounds (680 kg) in towing capacity - an increase from 6,500 pounds (2,948 kg) to 8,000 pounds (3,629 kg). A host of additional powertrain revisions contributes to the H2's improved performance and efficiency:
- Larger-capacity cooling system complements larger, more powerful engine
- Electric engine cooling fans reduce "drag" on engine, enabling more horsepower
- Regulated voltage control maximizes fuel economy by charging electrical components only when necessary
- New LAN electrical architecture is more efficient and uses less electrical energy
- Standard 3.73 rear axle ratio

Complementing the H2 lineup's performance and comfort changes are enhancements to the safety system. They include several new standard features:
- Roof rail head curtain side air bags for first-, second- and third-row passengers with rollover sensing system
- Safety belt pretensioners (first-row seats)
- Electronic stability control system with rollover mitigation technology
- New traction control system
- Tire pressure monitoring system

2009 Hummer H3T Sportsman
The Hummer H3T Sportsman concept enhanced the Hummer H3T Alpha’s inherent functionality with a combination of powertrain modifications, suspension enhancements and a balanced selection of Genuine HUMMER Accessories and aftermarket components. Starting with a new Hummer H3T Alpha, engineers added nearly 70 horsepower to its 5.3L V-8 via components available in the aftermarket. They include LS2 cylinder heads, a higher-lift camshaft and supporting components. Also enhancing performance is a custom, 3.5-inch exhaust system.
The H3T rides on 35-inch-tall BF Goodrich All-Terrain T/A tires mounted on HUMMER Accessory 20-inch wheels. The concept also uses racing-proven stock and aftermarket suspension components, including Light Racing JounceShocks and 2-inch-diameter Rod Hall Racing piggyback reservoir-type performance shocks. The modified suspension improves the H3T’s inherent off-road capability for traversing all forms of terrain.
To enhance the storage flexibility of the H3T’s 5-foot bed and standard bed-rail system, the Sportsman includes right- and left- side lockable storage boxes from HUMMER Genuine Accessories, perfect for securing valuable hunting and fishing gear.
Additionally, the Wildrye Matte custom paint is highlighted by functional HUMMER accessories, including grille-mounted and custom low-profile front- and rear-facing roof-rail mounted Delta off-road lamps, a body-color upper grille and a matte finish fuel door. A Predator Motorsports H3 winch mount system with a Warn XD9000 winch and Viking Off-Road synthetic winchline and Expert Recovery Kit provide the necessary recovery tools for any situation.
