2004 Hummer H1
2004 HUMMER H1: ONE OF A KIND
"Unique." "The original." "The world's premier off-road vehicle." There are many ways to describe the HUMMER H1. Also fitting is "cornerstone," since it's the foundation upon which the HUMMER sales growth is built.
"The H1 is what started it all for HUMMER," said Michael C. DiGiovanni, HUMMER general manager. "It's the vehicle that drew the interest of adventurous consumers across the nation, as well as the interest of GM. It offers superior off-road capabilities rugged enough for the Baja and powerful highway performance."
More power and plenty of poise
HUMMER H1 is powered by a retuned 6.5L, turbo-diesel V-8 engine that for 2004 delivers 205 horsepower (152 kw) at 3400 rpm and an impressive 440 lb.-ft. (596 Nm) of torque at 1800 rpm. That's 10 horsepower (7 kw) and 10 lb.-ft. (14 Nm) of torque more than the 2003 powerplant. Yet enhanced performance is only part of the engine's story. The retuning also enables the 6500 to meet the more stringent emission requirements starting in 2004. It's mated to GM's Hydra-Matic 4L80-E electronically controlled four-speed automatic transmission. Over time, this transmission monitors the customer's driving technique and adjusts for driving style. The New Venture Gear Model 242 transfer case enables the driver to customize the drivetrain configurations to match virtually any terrain.
H1 has a four-wheel fully independent suspension system and variable-rate heavy-duty coil springs. The front suspension incorporates a large stabilizer bar to improve handling and reduce sway when cornering. The truck's four-channel ABS four-wheel power disc brakes are mounted inboard as a component of the axle assembly, making them less vulnerable to damage than conventional wheel-mounted components.
"There's still nothing else on the road today with the panache of the H1," said DiGiovanni. "No other SUV can match its off-road capability and no other SUV - and very few vehicles in general - have the attention-grabbing styling of the H1. It remains the foundation upon which to build the HUMMER future."

2008 HUMMER HX Concept
General Motors is known to have had its eye on the niche occupied by the Jeep Wrangler. And at the Detroit auto show next month, it may reveal more of its intentions to field a Wrangler competitor in the shape of the HUMMER HX concept.
The HX Concept, shown in sketches at a GM press event today, also embodies some of the off-road hallmarks of the Toyota FJ Cruiser. BUT GM says the design of the new HX concept is all HUMMER, even though it's the work of three new designers.
David Rojas, Min Young Kang, and Robert Jablonski are the artists GM assigned to envision a future off-road vehicle for the HUMMER brand. All three are graduates of the College for Creative Studies in Detroit. The vehicle would have to evince HUMMER's off-road credentials while passing muster with Carl Zipfel, the director of the brand's design studio.
The resulting HX concept shares some elements with other HUMMER vehicles, like its flex-fuel-capable powertrain. But as the HX model is smaller and is a two-door vehicle, it has some stylistic touches uncommon to other HUMMER vehicles. The roof, for example, has removable panels and a removable rear roof that converts the HX from hardtop to an open-air vehicle with a short truck bed. The doors and fender flares are removable, too.
Stay tuned for more pictures and details on the HX concept as TheCarConnection.com covers the Detroit show debuts through January 15, 2008.

2007 Hummer Racing
HUMMER H3 Alpha and H3 first stock class vehicles to finish Baja.
Racing legend Rod Hall earns 19th career win in 40th Anniversary race
DETROIT – Team HUMMER once again demonstrated the inherent off-road capability of the HUMMER H3 as Rod, Josh and Chad Hall piloted their stock class H3 Alpha and H3 nearly 1,300 miles to become the first stock class vehicles to finish the 2007 SCORE International Baja 1000. The 2007 Baja 1000 marked the 40th anniversary of the grueling off-road race and covered 1,296.39 miles from Ensenada in Baja California to Cabo San Lucas, Mexico, Baja California Sur. It ran from November 13-15, 2007.
Team HUMMER races in the SCORE International full and mini stock classes which feature production-based vehicles with stock frames, stock suspension designs and production-based engines. With 18 entries, the 2007 race boasted the most stock class vehicles in the history of the 1000 and included models from seven different automakers.
As the only racer to have competed in a car or truck in all 40 Baja 1000 races, Team HUMMER owner Rod Hall marked his 40th race with a victory behind the wheel of his #760 stock mini class H3. Hall shared driving responsibilities in the race with his eldest son Josh Hall and business partner Mike Winkel. The trio piloted the vehicle to victory in 40:04:30 hours averaging a speed of 32.34 miles per hour. The H3 was the second stock class vehicle to cross the finish line.
The first stock class vehicle to cross the finish line was the #863 Team HUMMER H3 Alpha, piloted by Chad Hall and Sam Edgar. The team drove the H3 Alpha to a full stock class victory in its inaugural race, finishing in 36:27:25 hours and averaging a speed of 35.56 miles per hour.

First Drive: 2008 Hummer H3 Alpha
After two years of lion styling with housecat horsepower, Hummer’s runt of the litter finally gets a V-8 variant, dubbed the H3 Alpha. With 300 horsepower and 320 pound-feet of torque, the Alpha’s 5.3-liter V-8 is the mill the H3 should have had all along. Surprise, surprise—we like it better even though we still don’t love it.
Not Enough Power?
When Hummer introduced the H3, it was steadfast that its new baby had plenty of grunt, although we certainly wouldn’t have used that word to characterize the 220 horsepower of the original inline-five. Still, without admitting fault, the 3.5-liter was hastily bored to 3.7 liters for 2007—and horsepower rose to a still-not-enough 242. We kept bitching.
Why were we being so hard on it, GM wondered? Man, had anyone at the company driven it? On the road? Sorry for being so demanding, but we’ve never found 0-to-60 times in the mid-10-second range to be terribly stirring, especially in this day and age when there are SUVs that can be going a mile a minute from a dead stop in half that time. Granted, most of ’em aren’t worth much off-road, but still….
Turns out, even 300 horsepower under the H3’s chunky hood may not be enough. Sure, we were doing our on-road driving at more than a mile above sea level, on high-speed two-lanes between northern New Mexico’s noted (but fabulously unspoiled) Rock Garden off-road area and Durango, Colorado. But even with two aboard and no luggage, the Alpha’s 4900 pounds asked more of the wheezing OHV V-8 than it seemed willing to give. Backing that up is Hummer’s claim that the Alpha hits 60 mph in a just-okay 8.0 seconds. That’s slower than the much larger (albeit much more powerful) 2008 H2, which can hustle its 6650 pounds to 60 in a reasonably impressive 7.8 seconds with a 393-hp, 6.2-liter V-8 and six-speed automatic.
Much of the blame for the H3’s lackadaisical thrust can be attributed to the modest gear spread of the H3’s four-speed automatic, which was retained on account of insurmountable underhood packaging constraints. Hummer engineers admit—begrudgingly—that we’re going to be stuck with it until the next all-new H3 comes along, which won’t be happening any time this decade.
Engineers Were Busy
Certainly, said engineers already had enough to do in their efforts to squeeze the longer, wider, and heavier small-block V-8 into the tight engine bay of the H3, designed as it was for the narrower inline-five. Thus, according to H3 chief engineer Lee Visci, parts of the front-of-dash panel had to be moved rearward, and the frame had to be modified so the engine mounting points could be accommodated and a new, heavier-duty cooling system could be installed. The transmission was modified to accommodate a larger-diameter torque converter, and the front anti-roll bar was beefed up to handle the 100 pounds of additional weight.
Packaging of the exhaust system and the application of 2009 emissions controls made it impossible for Visci’s team to achieve the same horsepower and torque figures for their version of the 5.3 as, say, those in other GM applications, such as the 2007 Chevrolet Silverado, where it makes 315 horsepower, or even the ’07 Hummer H2, where it produces 325. “We had to work very hard for that 300 figure,” Visci said. But she added that the team is very satisfied with the results of its efforts, which included a one-third increase in towing capacity to a now-credible 6000 pounds, as well as meeting the same safety standards (specifically for cabin intrusion in severe frontal collisions) as the inline-five model’s.
Off-Road Strength
The Good Part: Even Better Off-Road
Where the H3 Alpha proves nothing short of brilliant is where Hummers usually prove themselves: off-road. Indeed, off-road is where the Alpha’s combination of reasonable size; spectacular wheel articulation; uncanny approach, departure, and break-over angles; and, alas, effortless torque—multiplied by the 4.10 final drive and low-range transfer case—makes a strong case for itself. Climbing up and down the ancient mesas and ravines of the Rock Garden (some seriously gnarly stuff) was so easy a caveman—or even an automotive journalist, for that matter—could do it. Credit must also be issued to the traction enhancement provided by the locking rear differential, without which we might never have gotten out of some of the holes in which we found ourselves. That and the fact that we let most of the air out of our tires.
On the Right Track, but Not Quite There Yet
There on the bluffs, we noted the numerous bones thrown at comfort and style for the $39,260. (That’s $8565 more than a base H3, and the total rises to $43,730 with the H3X bling package.) The window switches are relocated to the door panels (standard across the H3 line), “Alpha” badges and embossments are applied here and there, and all the goodies that come with the normal H3’s Luxury and Chrome packages were made standard. Also added is a silver front bumper that meets new car-to-car crash standards.
Back on the highway, however, we yearned for something more. Yes, the revised steering system adds some much-needed precision to the H3’s straight-line demeanor. But we hoped for less road rumble and more exhaust burble at speed, and the on-road ride remains as brittle as ever, with no changes made to the rear leaf springs. And then there’s that pesky fuel-consumption problem.
We believe Hummer is on the right track with the H3 Alpha, but it would be much better with more gears and less weight. Perhaps when the smaller and potentially more nimble H4 hits the market in 2009 or so, Hummer will finally have a product that makes its drivers just as happy on the road as off.

2008 Hummer H2
(from General Motors Press Release) 2008 HUMMER H2 DELIVERS GREATER CAPABILITY AND COMFORT, RETAINS ICONIC DESIGN
All-new interior features refined, premium appointments, all-new instrument panel and all-new, more comfortable seats with a full third row
New standard safety features include new electronic stability control system with rollover mitigation technology, panic brake assist and roof rail head curtain side air bags with rollover sensing system
All-new 6.2L V-8 and six-speed automatic combination delivers more power and efficiency
Towing capacity increased to 8,000 pounds (3,629 kg)
NEW YORK – 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 2008 HUMMER H2 represents a major step in the evolution of this iconic vehicle,” said Martin Walsh, HUMMER general manager. “From performance to comfort to safety and overall refinement, the new H2 lineup delivers more of what customers expect from HUMMER; they will be especially impressed with the new, more refined interior.”
HUMMER revealed the 2008 H2 at the New York Auto Show. The powertrain, interior and exterior changes also are included on the H2 SUT. The ’08 H2 and H2 SUT go on sale later this year.
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.
“This is one of those rare instances where enhanced performance is matched with improved efficiency,” said Walsh. “More power in the H2 helps make highway maneuvers, such as entering from a freeway on-ramp, feel effortless while simultaneously bolstering towing capability.”
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 new interior delivers a refined, premium feel while maintaining HUMMER’s trademark ruggedness,” said Dennis Burke, interior designer. “Everything from the flushness of the controls to the feel of the materials exudes craftsmanship in the H2’s new interior, while the fine details, like leather seat piping, create a consistent, premium interior design style across the entire HUMMER family.”
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.
Numerous available comfort and convenience features are either new or carried over into the ’08 H2, such as a new rear-seat overhead DVD entertainment system, a navigation system, a rear-view camera system and heated windshield washer fluid. OnStar and XM Satellite Radio are standard.
The ’08 H2 also offers a remote starting system that enables the vehicle’s interior to be heated or cooled prior to driving.
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, including:
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. 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
Also new is a panic brake assist feature – 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.
A self-leveling rear air spring suspension system is available for extreme off-road and towing requirements.
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.
Practicality aside, 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.

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, including:
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. 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
Also new is a panic brake assist feature – 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.
A self-leveling rear air spring suspension system is available for extreme off-road and towing requirements.
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.
Practicality aside, 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.

"International" Hummer H3
MANCHESTER, U.K. — It's a watershed moment for one of the most iconic American brands. General Motors on Monday took the wraps off a prototype right-hand-drive Hummer H3, which signals the Detroit brand's commitment to making serious inroads into foreign markets.
The automaker said the right-hand-drive H3 will be built in South Africa and will be rolled out to right-hand-drive markets including South Africa, Australia and Japan starting this summer. Pricing for the right-hand-drive H3 will be announced later, GM said.
"We are determined to build on the brand's unique recognition in Europe and especially here in the U.K.," said GM Vice Chairman Bob Lutz at the opening of a new Hummer showroom here.
Hummer reported that its sales grew nearly 34 percent globally in 2006 with 82,000 vehicles delivered, compared with 61,000 in 2005.
The H3 is powered by a 3.7-liter inline-5 that makes 242 horsepower and 242 pound-feet of torque. It is linked to either a four-speed automatic transmission or a five-speed manual transmission.

GM's Street-Fighting Transformer Vehicles Rev Up
DETROIT — Until now, moviegoers only got a quick glimpse of the Chevrolet Camaro that stars in Paramount's upcoming Transformers movie via a trailer that hit theaters late last year. The brief clip also offers teaser images of the GMC TopKick truck, Hummer H2 and Pontiac Solstice that will star in what is likely to be the blockbuster film of the summer.
But General Motors took the edge off this weekend, releasing several images of its four Transformer vehicles. The Chevrolet Camaro is undoubtedly the über-Transformer, dubbed "Bumblebee," a major character in the saga of aliens who take mechanical forms when on earth. GM said it will "roll out a fully integrated marketing and promotional effort around the film in the near future, including a major Chevrolet promotion."
Insiders say this effort may include specially badged vehicles to commemorate the film, as well as the usual line of toys, posters and other movie-related accessories.
GM vehicles are not merely static displays in Transformers. They are clearly embedded in the story line. "Autobot Jazz" converts from a hardtop Pontiac Solstice. "Autobot Ratchet" is a Hummer H2 that has been modified to serve as a rescue vehicle. "Ironhide" changes from a GMC TopKick medium-duty truck.
The movie will hit theaters July 4.

Hummer goes global with new H3 model
The Hummer brand goes global with the introduction of the Hummer H3. Developed for markets around the world and built in South Africa, the H3 adds unique styling features to the marque''s iconic shape, an all-new interior design and a 3.7-litre engine with, for the first time on a HUMMER, a choice of manual or automatic transmissions for the full-time four-wheel drive system. A right-hand drive version will be available summer 2007.
In the beginning Hummer was a vehicle in a class of its own, with extreme style and capability, unmatched and untouched by the competition. The latest chapter in the story is the Hummer H3, designed in response to demand from global markets for a luxurious everyday driving vehicle, offering the legendary Hummer performance.
H3 packs authentic Hummer style and capability into more compact dimensions. Compared to the Hummer H2, the H3 is 39 mm shorter, 171 mm lower and 73 mm narrower. Roughly the same length as a larger family saloon, H3 can navigate city traffic, yet still deliver HUMMER’s trademark crawling and climbing capability off-road.
The 4,782 mm long Hummer H3 is powered by General Motors’s Vortec 3.7-litre, inline five-cylinder engine with dual overhead camshafts and variable valve timing. Specifically designed for this type of vehicle, it delivers 244 hp (180 kW) at 5600 rpm and 328 Nm of torque at 4600 rpm.
H3 is the first Hummer ever to offer the choice of a manual or an automatic transmission. In addition to the Hydra-Matic 4L60 electronically controlled four-speed automatic transmission, a smooth-shifting five-speed manual transmission is available, the first-ever for HUMMER, offering ultimate driver control.
At the heart of the Hummer H3’s capability is its electronically controlled four-wheel drive system. The system is augmented with traction control, an optional locking rear differential and StabiliTrak stability control, which is offered as standard. The H3 can Ford 407 mm deep water at 20 mph or 610 mm deep streams at a 5 mph pace, and climb 407 mm vertical steps or rocks.
This off-road performance is also aided by the “wheel at each corner” design giving a maximum approach angle of 37.5 degrees and maximum departure angle of 34.6 degrees. These approach and departure angles permit the H3 to drive into a hole and back out again, without getting hung up at the front or the rear.
The H3’s more compact size provides manoeuvrability advantages, such as a
11.3 m turning circle, making equally easy work of parking manoeuvres or tight turns when off-roading. A 216 mm ground clearance and maximum breakover angle of 23.5 degrees make it possible to clear large obstacles in off-road driving.
Until recently, Hummer had primarily focused its attention on establishing a strong presence in North America. GM acquired the brand in late 1999 and since then Hummer sales have grown from around 1,000 vehicles per year in 2000 to more than 60,000 in 2005.
The H3 made its debut in North America in May 2005 and has helped make Hummer the fastest growing automotive brand in the United States. The H3 has made the brand more accessible with its smaller, more efficient package, while still retaining the characteristics that make a Hummer unique: iconic design and unparalleled off-road performance.
In addition to growth in the United States, Hummer has shown significant expansion around the globe. In Europe, where Kroymans Corporation has the exclusive rights to import and distribute Hummer vehicles in 27 European countries, sales have more than doubled since 2005. The H3 is a specific response to this rising customer demand. In the first 11 months of 2006,
1,712 HUMMERS were sold, compared to 548 vehicles in 2005.
While all previous Hummer H3s have been assembled in GM''s North American facility in Shreveport, Louisiana, the new international H3, intended for all markets outside of North America, is being assembled at the Struandale Assembly Facility in Port Elizabeth, South Africa. The $100 million investment in the plant has been described as one of the most important milestones in the history of GM in South Africa.

Hummer: Bio-fuel-ready engine
Who'd have thought that Hummer will be in the vanguard of car makers pushing for greener fuels?
The all-American icon is coming to the UK with right-hand-drive vehicles in the autumn of 2007 and has promised these cars will be followed by bio-fuel compatible versions within three years.
A Hummer insider told us that the company will be taking 'an aggressive approach' to putting forward the case for more fuel stations equipped with bio-fuel pumps.
The first Hummer to come with a bio-fuel-ready engine will be the 'baby' H3, which uses a 3.7-litre five-cylinder unit.
Hummer also promises it will add a diesel engine to the H3 range in 2008, but there are no firm dates or details as yet.
All of this means you can look forward to upsetting the tree-free brigade with a Hummer that's environmentally sound. Well, almost.
