Hummer H3T Alpha, 2009

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 offered in four trim levels, including five-cylinder models and the popular, V-8-powered H3T Alpha edition. Production is scheduled to begin in the third quarter of 2008 at GM's Shreveport, La., assembly plant, with vehicles arriving at HUMMER dealerships shortly thereafter. HUMMER will sell The Hummer H3T in North America, Europe and the Middle East.

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.

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.

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.

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.

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.

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

Complementing the features that enable The Hummer H3T's impressive off-road prowess are a host of first-class protective elements, including four standard skid shields: a front shield, an oil-pan shield/front-axle shield, a transfer case shield and a fuel tank shield.

Safety
Continuing HUMMER's tradition of delivering a broad range of safety systems, The Hummer H3T offers the following standard features:

•  Dual frontal air bags with GM's passenger sensing system
•  Head curtain side-impact air bags
•  StabiliTrak electronic vehicle stability control system

Hummer HX Concept, 2008

 

 

 

 

 

Hummer HX Concept, 2008

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, reconfigurable off-roader at the 2008 North American International Auto Show.

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 offers an open-air driving experience via a pair of removable roof panels above the driver and front passenger, and a modular, removable rear roof assembly. With the roof panels and roof assembly removed, the HX is transformed into a true convertible.

Easy removal of the roof panels and rear-roof assembly enables quick conversion from a closed vehicle to an open one. The HX also was designed with several roof assemblies, allowing this versatile vehicle to be configured as an SUT (with the roof assembly removed), a stylish slant-back or a traditional, wagon-like design that offers a bit more cargo space.

The 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

Purposeful exterior
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.

Inside and out, the HX carries a purposeful aesthetic that, from initial sketches to finalized clay models, was refined in only six months.
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.

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.
A rubberized floor and ballistic nylon-material covering on the instrument panel and other interior components reinforces the functional aesthetic.

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.

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.

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.

Hummer H3 Alpha, 2008

 

Hummer H3 Alpha, 2008

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

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.

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.

The H3 Alpha and the entire 2008 H3 lineup are standard head curtain side air bags; they were previously optional.

Standard safety features on all H3 models:

•  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

The 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, 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

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.

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.

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.

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 HUMMER announced the 2008 H2, with a completely redesigned, more refined interior that combines luxury with HUMMER's legendary ruggedness; enhanced safety features and a more powerful engine that is coupled with a new, six-speed automatic transmission. The new powertrain combination improves efficiency when compared with previous models.

The new powertrain combination consists of a 6.2L all-aluminum small-block V-8 engine, rated at 393 horsepower (293 kW) - an increase of about 20 percent over the previous engine - and a Hydra-Matic 6L80 six-speed automatic transmission. Performance-optimizing engine technologies, such as variable valve timing, and the six-speed's wide gear ratios, including a "tall" overdrive gear, enable the improved performance and efficiency over previous models.

All-new, luxury-appointed interior
While drivers will feel the '08 H2's improved performance on the road, they'll appreciate it more while experiencing it in the all-new interior. It features a completely redesigned instrument panel, new seats - including a full third-row seat for two passengers- new door trim panels, new controls, new rear-seat heating/air conditioning system, new rear-seat overhead DVD entertainment system and a new family of premium radios.

The seats in the H2 have a new, chiseled appearance and offer improved comfort. In fact, HUMMER engineers focused on every detail to improve interior comfort. For example, the front seat safety belts are now mounted to the vehicle's B-pillars rather than to the seats themselves. This change enabled engineers uncompromised comfort tuning for the seats. Front seat safety belt pretensioners are new, too, and are standard.

Complementing the new seats are new door trim panels and an all-new instrument panel and six-gauge instrument cluster that features a more refined appearance and better tolerances. In fact, the new interior is designed with interior gap tolerances of one millimeter or less. Soft-touch materials and new, more tactile controls enhance the feeling of craftsmanship. A new center stack houses the climate controls and a new family of GM radios - including a standard premium Bose audio system and an available surround sound system. The instrument panel also features new vents that enhance heating or cooling comfort throughout the vehicle - particularly for the second- and third-row seats.

Driving experience
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 also 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 six-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 also 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

Off-road acumen also was enhanced with the new powertrain system. The 6L80 transmission's tap up/tap down feature provides more control on grades and it offers automatic grade braking. It also improves the off-road crawl ratio to approximately 39:1 - an improvement of about 20 percent.

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. The several new 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

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 H2 SUT also offers an open, invigorating driving experience. At the push of a single button, the driver can lower all four side windows and the rear window. Using a separate switch, the standard sunroof can also be opened, giving SUT a truly open-air feeling.

Hummer H1 10th Anniversary Edition, 2002

 

The Hummer H1 is a civilian vehicle based on the High Mobility Multipurpose Wheeled Vehicle (HMMWV), popularly known as the Humvee, which was created by AM General.

History
Originally released in the civilian market in 1992, the Hummer H1 owes its birth to the popularity of photos from Operation Desert Storm and the enthusiastic campaign from actor Arnold Schwarzenegger, who personally owns several variants of Hummer vehicles. GM announced that 2006 would be the last model year for the Hummer H1 with production winding down in June 2006, due to a new emission laws for Diesel engine vehicles which take effect in 2007. No version of the Hummer H1 ever produced would meet these new standards. AM General currently has orders for an excess of 50,000 new HMMWVs to be produced between 2006-2009 for the United States Military. AM General also will continue to produce the H1, just not the Alpha. These vehicles will be sold through Fleet sales. The next H1 will most-likely bear a refined version of the prior 6.5L Turbo Diesel engine, but that has not been confirmed. Selling the H1's through fleet sales will allow the AM General to not be subjected to the new emission rules and regulations. AM General has sufficient fleet orders to produce 600-800 units per year right now.

Specifications
The Hummer H1 has three common variants: a convertible-like soft top, a four-door hard top pickup truck and a Wagon body version. Other less known variants include a two-door pickup truck and a four-door slantback. At this time, the convertible/soft top and the station wagon versions are the only ones available in the mass market. The two door and four door pickup versions are only available in fleet livery.

Five engine types and three automatic transmission types can be found in Hummer H1s. The common engine/transmission combinations are:
    * 6.2 L Detroit Diesel V8/GM TH400/3L80 3-speed

Hummer H2 SUV Concept, 2002

Hummer H2 SUV Concept, 2002

 

The H2 is the second vehicle sold under the Hummer marque of General Motors. It is a large SUV (though smaller than the Hummer H1) with room for five passengers and substantial off-road ability. The rearmost part of the H2 SUV was modified to a pickup truck bed for the 2004 H2 SUT ("Sport Utility Truck").

Overview
The H2 is built under contract by AM General at a specially constructed plant in Mishawaka, Indiana, USA. Although it shares GM's GMT820 truck platform with the Chevrolet Tahoe and GMC Yukon, those vehicles differ in many ways and are constructed in three other GM plants. The H2's final frame assembly is made up of 3 sections: The front uses a modified GM 2500-Series utility frame, the mid-section is all new and is completely boxed, and the rear section uses a modifed GM 1500-Series frame which is upgraded for the 8000 pound (3629 kg) gross vehicle weight.

H2 sales were initially strong, but fell to 28,898 for 2004 and 23,213 for 2005.
The H2 was nominated for the North American Truck of the Year award for 2003.

Engine
2003–2005 6000 6.0 L (366 in³) V8

Capabilities
With its high ground clearance, large tires, protective underbody plates, and low gearing, the H2 is capable of climbing over a 20-inch-high (0.4 m) step-up wall. A massive truck frame and wide track offer stability against overturning compared to some of the more common light truck SUVs, although objective tests have not been performed by the government or other outside parties due to its specialised vehicle class.

Fuel economy
For typical travel on improved roads, users report fuel economy of between 10 and 14 miles per gallon, which converts to between 14 and 17 L/100 km. Worst case urban driving is said to be in the range of 8 to 14 U.S. mpg (21 to 25 L/100 km). Although General Motors does not provide official H2 fuel economy ratings, most reviews have observed high single to low double-digit mileage, similar to the numbers above.

It should be noted that other large vehicles also have poor fuel economy especially with optional larger engines including the Dodge Ram 1500 series pickup trucks equipped with either the 8.3L V10 (MSRP US$48,500) or the 4.7L V8 Flexible Fuel engine running E85 fuel (MSRP US$31,300). Both of these engines are rated at 9 U.S. mpg city and 11 U.S. mpg highway by the E.P.A. as one example.

Criticism
The Hummer H2 is one of the most severely criticized civilian vehicles on the market today. Critics have expressed concern at the fuel economy which they cite as being among the most inefficient of vehicles. The Environmental Protection Agency does not test them for fuel economy because of their weight, they are thus categorised as light trucks and thus are not bound to fuel economy standards.

The Hummer H2 is criticised for contributing towards petroleum comsumption in the United States. In addition, they are criticized for obstructing the views of drivers behind them with their large vehicles. Criticism is also leveled at the H2 by safety advocates who have expressed concern that their size and height make them far deadlier to smaller vehicles as well as bicyclists, and pedestrians since the front of the Hummer H2 will likely strike the head and/or chest where injuries are far more life-threatening instead of the knees where regular cars are most likely to impact a pedestrian.
