2006 Hummer H3: What's New

Vehicle Overview
The latest model from General Motors’ Hummer brand was created to attract a broader range of potential buyers. Like the mammoth H1 and the large H2, the new H3 promises authentic Hummer style and offroad capabilities in a smaller, more fuel-efficient package.

Hummer claims the H3 is about the same length as a typical midsize sedan — and therefore is able to maneuver through urban traffic. When necessary, however, the H3 can demonstrate Hummer’s famous crawling and climbing abilities just like its larger siblings. The H3’s ground clearance is 9.1 inches, and it can turn in a 37-foot circle.

This is the first Hummer offered with either a manual or an automatic transmission. Its four-wheel-drive system is augmented by standard traction control and GM’s StabiliTrak electronic stability system, which is also standard in H3s with an automatic. Sales began in spring 2005.

Exterior
The H3 is easily identifiable as a Hummer due in part to its short overhangs, pronounced fender flares, upright windshield and windows, wide track and immense tires. Flat, chiseled surfaces also make the H3 noticeable. A seven-slot grille that’s flanked by round headlights within square openings sits up front. Front tow hooks are standard. The rear swing gate incorporates fixed glass and a door-mounted full-size spare tire.

Compared with the Hummer H2, which is based on a GM full-size truck platform, the H3 is 16.9 inches shorter overall and 6.5 inches narrower. Its height is 6 inches lower. Two tire types are available: a 32-inch all-terrain Goodyear tire and a 33-inch Bridgestone tire. Six-lug 16-inch aluminum wheels are standard, but chrome wheels are available. A sliding sunroof is optional.

With the optional 33-inch tires, the maximum breakover angle is 25 degrees. Offroad enthusiasts may also need to know that the H3’s maximum approach angle is 40 degrees and the peak departure angle is 37 degrees. The H3 can ford 16 inches of water at 20 mph or up to 2 feet if it slows to 5 mph. It can also climb 16-inch vertical steps and rocks.

Built on a ladder-type frame, the H3 has an independent front torsion-bar suspension and semi-elliptic leaf springs at the rear. The underbody includes four protective shields. An Off-Road Adventure Package enhances the vehicle’s offroad capabilities.

Interior
Five occupants fit in sporty bucket seats up front and a 60/40-split, folding rear bench. The driver faces a perforated leather-wrapped steering wheel and bright-accented instruments. Brushed, machine-finished trim plates are included. Controls on the center stack are arranged horizontally in four rows.

Four radio systems are available, and each is compatible with GM’s OnStar communication system and optional XM Satellite Radio. Cloth upholstery and remote keyless entry are standard, and three 12-volt power outlets are installed. Options include heated leather seats and a DVD-based navigation system.

Under the Hood
The H3 is powered by a 3.5-liter inline-five-cylinder that develops 220 horsepower at 5,600 rpm and 225 pounds-feet of torque at 2,800 rpm. Hummer claims the H3’s acceleration matches the pace of the larger H2’s for most driving conditions. Either a five-speed-manual gearbox or a four-speed automatic can be installed. The automatic unit includes shift modes that are specific to low-range operation.

The new BorgWarner two-speed, full-time, four-wheel-drive system has a 2.64-1 gear reduction for low range in order to yield satisfying control during offroad obstacle climbing. For ultimate climbing capabilities, an optional 4.03-1 ratio is available. A locking rear differential is optional. A Neutral position is included for flat-towing the vehicle.

Safety
Antilock brakes incorporate Dynamic Rear Proportioning. Side curtain-type airbags with a rollover system are optional. Daytime running lights and a tire-pressure monitoring system are standard.
