HUMMER declared the 2008 H2, with a totally redesigned, more refined inside that combines luxury with HUMMER's celebrated ruggedness; increased safety features as well as a far more powerful engine that's coupled with a brand new, sixspeed automatic transmission. In comparison with previous versions Efficiency is improved by the new powertrain combination.

"The 2008 HUMMER H2 represents an important part of the development of the iconic vehicle," said Martin Walsh, HUMMER general manager. "From performance to comfort to security and over all refinement, the newest H2 line delivers more of what clients expect from HUMMER; they are going to be particularly impressed with the new, more refined inside."

HUMMER unveiled the 2008 H2 at the Brand New York Auto-show. The exterior, interior and power-train changes are also contained on the H2 SUT. The '08 H2 and H2 SUT go for sale later in 2013.

The brand new powertrain combination includes a 6.2L allaluminum smallblock V-8 engine, rated at 393 hp (293 kW) - a rise of approximately 20 per cent over the last engine - and a HydraMatic 6L80 sixspeed automatic transmission. Performance-optimizing engine technologies, for example variable valve timing, as well as the six-speed's broad gear ratios, including a "tall" overdrive gear, empower the improved performance and efficiency over previous versions.

"This is certainly one of these rare examples where increased functionality is matched with improved efficiency," said Walsh. "More power in the H2 makes highway maneuvers, for example entering from the freeway onramp, feel effortless while simultaneously bolstering towing ability."

Allnew, luxurious-appointed interior

"The new inside delivers a tasteful, superior feel while keeping HUMMER's trademark ruggedness," said Dennis Burke, decorator.

Seats in the H2 have a brand new, chiseled look and offer comfort. Actually, HUMMER engineers dedicated to each aspect to enhance interior comfort. For instance, the front seat safety belts are actually mounted to the automobile's B-pillars as opposed to to the seats themselves. Front-seat safety belt pre-tensioners are new, also, and are conventional.

Complementing the new seats are new door trim panels and sixgauge instrument cluster and an allnew instrument panel that has a more refined look and better tolerances. Actually, the fresh interior was created with interior gap tolerances of 1 millimeter or less. Softtouch substances and new, more tactile controls improve the feeling of workmanship. A brand new center stack houses the climate controls plus a brand new group of GM radios - including an accessible surround sound system and a normal premium Bose audio system. The instrument panel also features new ports that enrich heat or cooling comfort through the vehicle - especially for the 2nd- and thirdrow seats.

OnStar and XM Radio are conventional.

The '08 H2 also provides a remote starting system which permits the vehicle's interior to be heated or cooled just before driving.

Driving experience

The center of the '08 H2 is really a brand new, 6.2L V-8 engine which uses variable valve timing technology to optimize performance and fuel economy. It's rated at 393 hp (293 kW) and 415 lb.ft. of torque (574 Nm).

The 6.2L V-8's technologically higher level features also make it meet new national emissions standards annually before compulsory implementation.

The sixspeed automatic has a broad, 6.04:1 complete ratio - including two overdrive gears - that helps produce an exceptional balance of performance and fuel economy. Also, the 6L80 has a "tap up/tap down" capacity that enables the driver to manually select up-shifts and downshifts having a button around the column shifter.

A range of added power-train revisions also plays a role in the H2's improved functionality and efficiency, including:

Regulated voltage get a grip on maximizes fuel economy by charging electric parts only when essential
New LAN electric architecture uses less electricity and is more effective
Standard 3.73 back axle ratio
Offroad acumen also was improved using the newest power-train system. Additionally, it enhances the offroad crawl ratio to around 39:1 - an enhancement of about one-fifth.

A fresh traction get a grip on system is also standard, which helps to ensure surefooted grip in many driving conditions.

Driving performance off the street or on is enhanced with a revised steering gear which has a quicker ratio and improved oncenter returnability. The experience is also much more tasteful and quieter, thanks to brand new, tuned air intake and exhaust systems.

Safety standard

Complementing the H2 line's functionality and relaxation changes are improvements towards the security system. They contain several new regular attributes:

Safety belt pre-tensioners (firstrow seats)
Electronic stability get a grip on system with roll-over mitigation technology
New traction get a grip on system
It's a regular feature on all H2 models. Also, the conventional OnStar system now provides the Turn - By - Turn navigation system. Additional optional attributes that contribute to some safer driving experience include HUMMER's Back Vision System - a rear-view camera system - and a navigation system.

Exterior improvements

All 2008 H2 models are recognized from previous models with functional changes that keep HUMMER's immediately recognizable design identify. The iconic, sevenslot grille features bigger openings as well as the reduced grille is also enlarged, accommodating the cooling necessities of the more powerful 6.2L V-8 engines.

The soul of the HUMMER

As the '08 H2 is offered having a fresh powertrain and inside, its base stays the same: a completely welded ladder-kind framework which includes a modular, threepiece layout comprising numerous hydroformed parts. This design provides outstanding strength, stiffness and dimensional precision.

The H2 has short overhangs for revolutionary approach and departure angles, and special ground clearance for minimal effect on trails. A fivelink rear suspension, heavyduty separate front suspension plus standard 17inch wheels provide exceptional handling, carrying and towing ability. Durable sure-footedness is ensured by the solid rear axle, especially in tight, offroad situations. Also standard is under-body rocking chair and protection protection.

A brand new, fourchannel antilock braking/traction control system (ABS/TCS) provides optimum control on slick surfaces. Additionally, the ABS can discover and correct its braking capabilities to rough offroad surfaces like gravel and pot-holes. The TCS also comprises the capability to get traction via just one wheel, if needed, and much more wheel skid in another traction get a grip on mode for desert and sand racing conditions.

A selfleveling rear air spring suspension system is accessible for towing requirements and extreme offroad.

H2 SUT - fun and maximum utility

With four passengers up to speed, the bulkhead in the back of the SUT's passenger compartment stays erect, still providing ample cargocarrying ability.

Practicality aside, the H2 SUT offers an open, invigorating driving experience. In the push of one button, the driver can lower the rear window as well as all four side windows. Utilizing a different switch, the sunroof may also be opened, giving a genuinely openair feeling to SUT.
