The next chapter of the growing HUMMER legacy, the 2006 H3 delivers authentic HUMMER style and off-road capability in a more accessible, midsize package.
H3 packs uncompromising HUMMER style and capability into its midsize dimensions. Compared to the H2, the H3 is 16.9 inches (429 mm) shorter in length, 6 inches (152 mm) shorter in height and 6.5 inches (165 mm) narrower. Roughly the same length as a midsize family sedan, H3 comfortably navigates city traffic and delivers HUMMER’s trademark crawling and climbing capability.
Powered by the Vortec 3500 engine with dual overhead cams and variable valve timing, the H3 is projected to reach peak fuel economy of up to 20 miles per gallon. Specifically designed as a truck engine, the Vortec 3500 is a 3.5L inline five-cylinder offering an excellent combination of power and efficiency. It delivers 220 horsepower (164 kw) at 5600 rpm and 225 lb.-ft. of torque (305 Nm) at 2800 rpm.
H3 will be the first HUMMER to offer the choice of a manual or an automatic transmission – either a standard, smooth-shifting five-speed manual transmission or a Hydra-Matic 4L60-E electronically controlled four-speed automatic transmission.
The H3 was engineered for off-road leadership among midsize SUVs. The heart of the truck’s capability is its electronically controlled four-wheel-drive system. The system is augmented with features such as traction control, underbody shielding, an optional rear locking differential and StabiliTrak stability control with the automatic transmission. H3 offers two tire packages, a Goodyear 32-inch, all-terrain tire and Bridgestone 33-inch off-road tire, both larger than those found on any other midsize SUV.
Among its off-road capabilities, the H3 can ford 16 inches (407 mm) of water at 20 mph or 24-inch (610 mm) streams at a 5-mph pace, climb 16-inch (407 mm) vertical steps and rocks, make its way through deep sand and race over sandy surfaces.
H3’s more maneuverable size provides advantages, such as a 37-foot (11.3 m) turning circle, about the same as a typical compact car, making easy work of parking lot maneuvers and tight turns when off-roading. The 9.1-inch (231 mm) ground clearance and maximum breakover angle of 25 degrees (with 33-inch tires) both make it possible to clear large obstacles in off-road driving. Serious off-road performance is also aided by the maximum approach angle of 40 degrees and maximum departure angle of 37 degrees. These approach and departure angles permit the H3 to drive right into a hole and back out again, without getting hung up in front or rear.
In addition to its uncompromised off-road capabilities, the H3 also provides the refinement, comfort and convenience required for enjoyable driving. It offers premium options such as heated leather seats, a large electric sliding sunroof, a DVD-based navigation radio and numerous customized accessories.
H3’s bold looks make it readily identifiable as a HUMMER. It’s a matter of form following function. Features such as its wide track width, short overhangs and huge tires provide stability, outstanding ground clearance and quick rock-climbing capability in off-road driving.
The H3’s flat, chiseled surfaces; upright windshield and windows; signature seven-slot louvered grille; round headlamps housed inside square openings; and pronounced fender flares are all pure HUMMER. Power and strength emanate from its cube-like metal billet form.
The H3’s interior is inviting and modern, blending premium cues with world-class craftsmanship. Upscale touches include a perforated, leather-wrapped and stitched steering wheel and automatic transmission shift handle; bright-accented instrumentation; brushed, machine-finished trim plates; chrome door release handles; chrome bezel for the automatic transmission shifter; and a chrome H3 emblem in the center of the steering wheel.
HUMMER owners value the inherent strength and feeling of security their trucks exude. The H3 fulfills that promise with available features such as standard StabiliTrak electronic stability control (automatic transmission), roof rail-mounted side curtain air bags, rollover protection system, and stout vehicle structure projected to earn top safety ratings for both the driver and passenger in front and side impacts.
OnStar-equipped H3s will feature OnStar Dual-mode (analog-digital) equipment. OnStar’s digital equipment also includes enhanced hands-free voice recognition capabilities including more intuitive continuous digit dialing and improved voice recognition accuracy. OnStar is the leading provider of in-vehicle safety, security and information services in the United States and Canada . Using the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Hands-Free Calling that allows drivers to make and receive voice-activated phone calls using an externally mounted antenna for greater reception.
The OnStar service standard on the 2006 H3s includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to the participating 911 centers to help them dispatch the appropriate life-saving personnel and equipment to crash scenes faster.
HUMMER owners value the inherent strength and feeling of security their trucks exude. The H3 fulfills that promise with available features such as StabiliTrak electronic stability control, roof rail-mounted side curtain air bags, rollover protection system, tire pressure monitor and stout vehicle structure designed to earn top safety ratings for both the driver and passenger in front and side impacts.
The H3 incorporates structural enhancements designed to help in crash protection, as well as a number of advanced safety systems to assist in both crash avoidance and protection, including a reinforced passenger compartment safety cage that helps provide protection in the event of side and frontal impacts. The strong, rigid steel structure surrounds the passenger compartment, runs from the A-pillars to the roof rail, back to the D-pillars and includes the bottom rocker panels, under-floor longitudinals and frame. The all-steel body panels and exceptionally strong frame further help protect occupants in a collision. The fully welded, ladder-type frame optimizes crash performance, in addition to standing up to rigorous off-road requirements.
Additional crash protection is provided by a standard frontal dual-stage air bag system. The H3 has GM’s Passenger Sensing System, which uses weight-sensing technology to turn the front passenger air bag on or off as appropriate. If the sensor system detects an unoccupied front passenger 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. Even with this system, GM strongly recommends restraining child passengers 12 and under in an appropriate child seat or, for older children, lap-and-shoulder belts in the second or third row of the vehicle.
Optional roof rail-mounted, side curtain air bags drop down to the belt line to help provide head and rollover protection for the driver and front passenger. A rollover protection sensing system also helps protect occupants against impending rollovers by triggering side curtain air bags to increase the likelihood of occupant containment in a rollover event. Seat belt pretensioners help keep occupants in the proper position, reducing their likelihood making contact with the inside of the vehicle.
