H3T Concept HUMMER Truck
No matter the dimensions or configuration, a automobile adorned with the HUMMER title should ship the best-in-class capabilities which have made the model the usual in opposition to which different off-road automobiles are measured. That’s definitely the case with the dynamic H3T, a midsize truck that infuses all of HUMMER’s military-derived DNA into an environment friendly, refined bundle and carves a brand new area of interest within the midsize truck market. HUMMER launched the ruggedly refined H3T idea automobile on the 2004 Greater Los Angeles Auto Show, offering a glimpse at a rising household of expressive, versatile automobiles.
“The H3T idea expresses a imaginative and prescient of the potential of future HUMMER automobiles, focused at fanatics who need the HUMMER picture and functionality, however in a smaller, non-SUV configuration,” stated Clay Dean, design director for small vehicles and HUMMER. “It additionally gives a visible clue to the evolution of HUMMER’s design.”
Innovative options abound within the H3T: The pickup field incorporates side-access doorways, together with drop-down help steps that additionally double as weather-tight storage compartments. The H3T’s distinctive tailgate kinds an unbroken load floor when down, contributing to the H3T’s versatility.
There’s additionally a big, power-operated folding canvas sunroof and drop-down rear window that mix to supply an open-air driving expertise. There wouldn’t be a HUMMER badge on the H3T if it didn’t have the potential to dive into twisty terrain that would depart lesser 4x4s spinning their wheels. Its wheels-at-the-corners stance, together with 34-inch-tall tires and 11.5 inches of floor clearance, offers the H3T a 51-degree method angle and a 50-degree departure angle – important measures on HUMMER’s inner “off-road efficiency metric” of capabilities.
And whereas the H3T delivers on the promise of its familial seems, it does so with a youthful, masculine aptitude. “Regardless for those who’re a person or girl, it brings out a rebellious aspect to you that harks again to youthful days,” stated Dean. “It’s an irreverent automobile – a nasty boy in a black tie.”
Riding on a 118.6-inch wheelbase and measuring 74.5 inches broad, the H3T embodies the basic HUMMER proportions – broad stance, low roofline, and wheels on the corners – which have made the H1 and H2 immediately recognizable all over the world. And just like the H1 truck, the H3T incorporates the cab and mattress in a single construction for enhanced power and an built-in look.
“This is a special measurement automobile, nevertheless it’s a HUMMER all through,” stated Dean. “The cab configuration is private and the smaller measurement makes the H3T extra manageable and fewer intimidating to some drivers than bigger automobiles. The smaller measurement additionally offers the H3T a extra sporting and dynamic driving sensation.”
H2H – Hydrogen Powered HUMMER
Design:
HUMMER is like nothing else, and the H2H carries that custom ahead. Not solely does the H2H carry HUMMER’s iconic design, it creates a daring and placing visible assertion on the way forward for hydrogen.
HUMMER designers took the chance to make the H2H a singular expression of HUMMER’s trademark look. The H2H is predicated on an H2 SUT (Sport Utility Truck) physique, with a number of enhancements. The SUT rear cargo mattress is roofed by a particular composite tonneau, giving the truck a “slant again” look. The slant again form is a brand new interpretation of a physique fashion created for the navy HUMVEE, the precursor and inspiration for HUMMER itself.
The H2H is instantly acknowledged by its Laser Blue exterior paint, a wealthy, deep colour by no means earlier than used on a HUMMER. A particular graphic on both sides of the physique declares the truck’s hydrogen gas utility, together with HUMMER’s assist for California’s Hydrogen Highway Network initiative. A particular built-in roof rack and lightweight bar sits atop the truck, with a singular chrome grille guard on the entrance.
On the within, designers once more took the chance to combine some one-of-a-kind touches. These additions not solely make the H2H extra distinctive, they’re additionally styling experiments permitting designers to check concepts which will affect future automobiles. These embody particular waterproof seats fabricated from a prototype nylon-based materials. Rather than splattering and soaking, spilled water hits this materials and instantly gathers into droplets perched on the floor of the seat that may be simply brushed apart.
H2H is provided with a rear leisure system, that includes DVD gamers with screens mounted into the headrests. The headliner of the H2H is fabricated from Ultra-Suede, a fabric that’s particularly mushy, luxurious and sturdy. The instrument panel incorporates a carbon fiber-patterned appliqué evoking the fabric used for the H2H’s gas tanks.
H2H – Hydrogen Powered HUMMER
Technology:
Many worthy experiments concerning hydrogen gas are being carried out on smaller, much less expressive and fewer rugged automobiles. The H2H is a uncommon alternative to use this idea to one of many world’s most rugged and distinctive automobiles – a HUMMER H2.
The H2H options the identical Vortec 6000 (6.0-liter V-8) engine utilized in all HUMMER H2s on the street at this time. This experimental automobile achieves a lot of the identical on-road driving traits and luxury of the H2, a serious accomplishment for such a sophisticated technological effort.
The dynamics of gas supply to an inner combustion engine are a lot completely different for gaseous hydrogen gas, in comparison with gasoline, because of the completely different combustion dynamics of those fuels. Specially designed gas injectors ship hydrogen to the engine extra conservatively than in a gasoline gas system, thus lowering engine energy. The H2H provides a supercharger mounted onto the Vortec 6000 to assist the engine reclaim a few of that deficit, reaching a peak of roughly 180 horsepower (134 kw).
The truck’s powertrain, fueling and electrical programs have all been extensively reconfigured to function with a devoted 350-bar compressed hydrogen gas system. This consists of three on-board carbon fiber gas tanks. Two tanks are mounted underbody within the approximate location of a conventional gasoline gas tank. The third is mounted within the H2 SUT’s rear cargo mattress. The three tanks mix to create 5.5 kg (12 kilos) of complete hydrogen storage.
The H2H’s hydrogen gas system together with gas injection, digital controls, ultra-light composite hydrogen storage, full with integral strain regulation and security programs, was developed in collaboration with Quantum Technologies (NASDAQ: QTWW), a California-based chief in packaged gas programs for hydrogen and one in all GM’s gas cell expertise alliance companions. In 2002, GM acquired a considerable minority possession place in Quantum to collaborate on bettering the vary of GM’s gas cell automobiles by way of the event of hydrogen storage, hydrogen dealing with and digital management applied sciences for gas cell functions.
The hydrogen refueling interface for the H2H follows the prototype design set forth in California. It consists of two connectors (one within the conventional fuel-fill location, the opposite on the rear bumper) that allow the quickest gas fill presently obtainable in California’s rising hydrogen infrastructure. In its early testing and growth, it’s estimated that the H2H can journey roughly 60 miles (97 km) between fill-ups.
GM’s foremost powertrain and automobile growth engineers within the U.S., Canada and Germany collaborated to create the H2H’s hydrogen gas system. The electronics and security programs of the H2H are state-of-the artwork for a hydrogen-powered automobile. In reality, the H2H’s security system is modeled after that used on GM’s Hydrogen3 minivan, GM’s record-setting hydrogen gas cell automobile.
GM is transferring very quick on lowering the price of gas cell stacks and proving expertise and industrial viability of gas cell expertise, and is dedicated to perfecting gas cells as a result of they’re extra environment friendly and cleaner than inner combustion engines. Therefore, there are not any plans at GM to supply the H2H or pursue hydrogen inner combustion engine expertise long run.

HUMMER Vision:
GM is transferring very quick on lowering the price of gas cell stacks and proving the expertise and industrial viability of gas cell expertise. GM is dedicated to perfecting gas cells as a result of they’re extra environment friendly and cleaner than inner combustion engines.
“As a part of our ‘march towards zero’ with gas cell automobiles, we have to be taught many issues in regards to the dealing with and storage of hydrogen and its use as a motorized vehicle gas,” stated Lowery. “We consider the H2H will enhance our understanding of utilizing hydrogen as a motorized vehicle gas and of making a viable hydrogen-refueling infrastructure.”
In addition to its experimental use, HUMMER will use the H2H to convey consideration to the promise of hydrogen, particularly the private and non-private partnerships required to create a hydrogen financial system. For instance, H2H can be used to assist illustrate necessary milestones within the growth of California’s Hydrogen Highway Network, an initiative that mixes the efforts of trade and authorities to develop that state’s infrastructure, analysis and financial growth efforts.
The H2H was created by a crew of GM engineers from the U.S., Canada and Germany, in collaboration with Quantum Technologies (NASDAQ: QTWW), a California-based chief in packaged gas programs for hydrogen and one in all GM’s gas cell expertise alliance companions.
HUMMER’s daring experiment
The H2H additionally makes a daring assertion for HUMMER.
“The H2H is a daring experiment showcasing HUMMER’s assist for long-term options to power and environmental challenges,” stated Susan Docherty, HUMMER basic supervisor. “It is one thing we will do proper now to assist assist GM’s long-stated targets of pursuing commercially viable gas cell applied sciences.”
Along these strains, HUMMER gas financial system will enhance in 2005. The midsize H3 debuts within the spring as an genuine HUMMER in a smaller and extra fuel-efficient bundle. Also in 2005, the unique HUMMER, the H1, will see a gas financial system improve of as much as 15 % with the introduction of the H1 Alpha mannequin geared up with the Duramax diesel engine.
