The new powertrain mixture consists of a 6.2L all-aluminum small-block V-8 engine, rated at 393 horsepower (293 kW)* – a rise of about 20 p.c over the earlier engine – and a Hydra-Matic 6L80 six-speed automated transmission. Performance-optimizing engine applied sciences, corresponding to variable valve timing, and the six-speed’s large gear ratios, together with a “tall” overdrive gear, allow the improved efficiency and effectivity over earlier fashions.
“This is a type of uncommon cases the place enhanced efficiency is matched with improved effectivity,” mentioned Walsh. “More energy within the H2 helps make freeway maneuvers, corresponding to coming into from a freeway on-ramp, really feel easy whereas concurrently bolstering towing functionality.”
All-new, luxury-appointed inside
While drivers will really feel the ’08 H2’s improved efficiency on the street, they’ll respect it extra whereas experiencing it within the all-new inside. It includes a fully redesigned instrument panel, new seats – together with a full third-row seat for 2 passengers– new door trim panels, new controls, new rear-seat heating/air-con system, new rear-seat overhead DVD leisure system and a brand new household of premium radios.
“The new inside delivers a refined, premium really feel whereas sustaining HUMMER’s trademark ruggedness,” mentioned Dennis Burke, inside designer. “Everything from the flushness of the controls to the texture of the supplies exudes craftsmanship within the H2’s new inside, whereas the nice particulars, like leather-based seat piping, create a constant, premium inside design model throughout your complete HUMMER household.”
Seats within the H2 have a brand new, chiseled look and provide improved consolation. In truth, HUMMER engineers centered on each element to enhance inside consolation. For instance, the entrance seat security belts at the moment are mounted to the automobile’s B-pillars moderately than to the seats themselves. This change enabled engineers uncompromised consolation tuning for the seats. Front seat security belt pretensioners are new, too, and are normal.
Complementing the brand new seats are new door trim panels and an all-new instrument panel and six-gauge instrument cluster that includes a extra refined look and higher tolerances. In truth, the brand new inside is designed with inside hole tolerances of 1 millimeter or much less. Soft-touch supplies and new, extra tactile controls improve the sensation of workmanship. A brand new middle stack homes the local weather controls and a brand new household of GM radios – together with a typical premium Bose audio system and an accessible encompass sound system. The instrument panel additionally options new vents that improve heating or cooling consolation all through the automobile – notably for the second- and third-row seats.
Numerous accessible consolation and comfort options are both new or carried over into the ’08 H2, corresponding to a brand new rear-seat overhead DVD leisure system, a navigation system, a rear-view digicam system and heated windshield washer fluid. OnStar and XM Satellite Radio are normal.
The ’08 H2 additionally presents a distant beginning system that permits the automobile’s inside to be heated or cooled previous to driving.
Driving expertise
The coronary heart of the ’08 H2 is a brand new, 6.2L V-8 engine that makes use of variable valve timing know-how to maximise efficiency and gas effectivity. It is rated at 393 horsepower (293 kW)* and 415 lb.-ft. of torque (574 Nm)*. The engine additionally options light-weight supplies, together with an aluminum cylinder block, which helps cut back the automobile’s general mass.
The 6.2L V-8’s technologically superior options additionally assist it meet new federal emissions requirements a yr earlier than necessary implementation.
A brand new six-speed Hydra-Matic 6L80 RWD electronically managed automated transmission backs the 6.2L engine. The six-speed automated has a large, 6.04:1 general ratio – together with two overdrive gears – that helps ship a wonderful stability of efficiency and gas financial system. Also, the 6L80 has a “faucet up/faucet down” functionality that permits the motive force to manually choose upshifts and downshifts with a button on the column shifter.
The new powertrain mixture helps the 2008 H2 and H2 SUT ship a further 1,500 kilos (680 kg) in towing capability – a rise from 6,500 kilos (2,948 kg) to eight,000 kilos (3,629 kg). A bunch of further powertrain revisions additionally contributes to the H2’s improved efficiency and effectivity, together with:
Larger-capacity cooling system enhances bigger, extra highly effective engine
Electric engine cooling followers cut back “drag” on engine, enabling extra horsepower
Regulated voltage management maximizes gas financial system by charging electrical elements solely when obligatory
New LAN electrical structure is extra environment friendly and makes use of much less electrical power
Standard 3.73 rear axle ratio
Off-road acumen additionally was enhanced with the brand new powertrain system. The 6L80 transmission’s faucet up/faucet down characteristic offers extra management on grades and it presents automated grade braking. It additionally improves the off-road crawl ratio to roughly 39:1 – an enchancment of about 20 p.c.
The switch case is improved within the ’08 H2; it’s stronger with improved efficiency. A brand new traction management system is also normal, which helps guarantee sure-footed traction in most driving circumstances.
Driving efficiency off the street or on is enhanced by a revised steering gear that has a faster ratio and improved on-center returnability. The driving expertise is also quieter and extra refined, because of new, tuned air consumption and exhaust techniques.
Safety normal
Complementing the H2 lineup’s efficiency and luxury adjustments are enhancements to the protection system. They embrace a number of new normal options:
Roof rail head curtain aspect air baggage for first-, second- and third-row passengers with rollover sensing system
Safety belt pretensioners (first-row seats)
Electronic stability management system with rollover mitigation know-how
New traction management system
Tire strain monitoring system
Also new is a panic brake help characteristic – the primary software for a full-size GM truck or SUV – which detects emergency braking conditions and maintains most brake strain to assist cease the automobile extra shortly and with extra management. It is a typical characteristic on all H2 fashions. Also, the usual OnStar system now presents the non-compulsory Turn-By-Turn navigation system.
