The HUMMER H3 | Part Four



Premium equipment for everyday Comfort and Convenience

In addition to its uncompromised off-road capabilities, the 2008 H3 also provides the refinement, comfort and convenience required for enjoyable everyday motoring.  It presents an inviting and modern interior, blending premium cues with high-quality craftsmanship.  Upscale touches include a chrome H3 emblem in the centre steering wheel boss, bright-accented instrument panel, chrome interior door release handles and a chrome bezel for the automatic transmission shifter.

The 2008 HUMMER H3 is equipped with a wide range of premium luxury fixtures and fittings.  Standard equipment on the SE model includes: air-conditioning, cruise control, radio/CD player with six-speaker audio system, powered windows (front and rear), electric power-adjustable door mirrors, a ‘electrochromic’ inside rearview mirror with compass and outside temperature indicator, plus two covered 12-volt auxiliary power outlets - one in front, one in the cargo area and remote keyless entry with two transmitters and panic button.

Both the Luxury and Adventure versions H3 come with eight items of additional equipment that include: a Chrome Appearance Pack, leather seats and interior trim, heated eight-way powered front seats, and an AM/FM radio/single CD, with MP3 disc-playing capability and a premium seven-speaker Monsoon sound system with subwoofer and amp.

As standard, the H3 Luxury also features 16-inch chrome alloy wheels, chrome bonnet louvre, chrome roof cross-bars and chrome tubular assist steps - while the H3 Adventure has heavy-duty off-road suspension and a 4.03:1 transfer case and locking rear differential - instead of the Luxury’s chromed additions.

Among the premium options available are an in-dash 6-disc CD changer, a touch-screen DVD-based navigation system, a large electric express open/close sliding glass sunroof and numerous customised HUMMER accessories.  These include roof marker lights, bright and black roof rack crossbars, a chrome–plated fuel filler flap in solid metal, an under-bonnet engine-bay liner with H3 logo moulded splash guards, a hard cargo carrier and roof or tailgate mounted carriers for bikes, skis, snowboards, or even canoes.

HUMMER high technology for off-road Supremacy

The 2008 H3 simply would not be a HUMMER if it didn’t deliver a class-leading performance off road.  The H3 is engineered for off-road leadership among midsize SUVs, with an electronically controlled four-wheel drive system, traction control, a (optional) locking rear differential and StabiliTrak stability control.

The standard 265/75 R16 Goodyear Wrangler all-terrain tyres have a 32-inch external diameter.  They are larger than those found on any other midsize SUV and provide optimum traction and an opportunity for increased approach, departure and breakover angles.

Serious off-road performance is also aided by the ‘wheel at each corner’ nature of the design which results in a maximum approach and departure angles of 37.0 and 34.6 degrees, respectively.  These angles permit the H3 to drive into a hole and back out again, without getting hung up in front or rear.

The 219 mm ground clearance and maximum breakover angle of 23.5 degrees make it possible to clear large obstacles during off-road driving.  Among its off-road credentials, the H3 can ford 407 mm of water at 20 mph or wade through 610 mm deep streams at a steady 5 mph pace.

The HUMMER H3 is equally at home making its way through deep sand or racing over sandy surfaces, or climbing 407-mm vertical steps or rocks.

State-of-the-Art Safety Equipment…

HUMMER owners value the inherent strength and feeling of security that their vehicles exude.  The 2008 H3 fulfils that brand promise with a range of ‘active’ and ‘passive’ safety technologies, including a robust all-steel chassis frame, steel body panels and a reinforced passenger compartment safety cage, plus features such as TCS, StabiliTrak, curtain air bags and rollover protection.

‘Active’ technologies that enhance stability include a standard-fit traction control system (TCS), that uses a combination of engine throttle reduction and braking one or more wheels, to provide impressive traction capability even when three wheels are slipping.

GM’s sophisticated StabiliTrak ESP-style electronic stability enhancement system is standard on the HUMMER H3.  Partnered with the new ABS brake and TCS traction control systems, it applies individual brakes to correct understeer or oversteer during emergency manoeuvres and ensure stability and traction.

StabiliTrak is always ‘on’ and its operation is fully automatic.  In the H3, the transfer case’s control algorithm has been integrated with both the StabiliTrak and ABS systems to provide enhanced vehicle stability by managing the front-to-rear, as well as the left-to-right torque distribution, as required, to achieve optimal control.

…’Passive’ protection for all occupants

The standard two front air-bags are advanced dual-stage bags, computer controlled to inflate to a greater or lesser extent - depending on the severity of the accident.  In H3 these bags are also controlled by GM’s Passenger Sensing System.  This uses weight-sensing technology to turn the front passenger air bag ‘on’ or ‘off’ as appropriate.  If the sensor system detects an unoccupied seat or the presence of a smaller occupant, the front passenger air bag is designed to automatically turn off so it would not deploy in the event of a frontal collision.

In the event of a roll-over, the standard full-length curtain air bags drop down from the interior roof rail to the belt line and help provide head and upper torso protection for all occupants.  The rollover protection sensing system also has a predictive ability, with motion monitors that can ‘sense’ an impending rollover and trigger the inflation of the side curtain air bags to increase occupant protection in the anticipated incident.

Three-point seatbelts are provided in all five seating positions, along with the Child safety seat Lower Anchors and Tethers for Children (LATCH) system in the outer rear seats.  Both front seatbelts feature pretensioners that help keep occupants in the optimum position to gain maximum benefit from the vehicle safety systems.
