GM introduced the Hummer H3 in 2006 as an entry-level Hummer for the masses. It features styling that is strikingly similar to its older brother, the H2. If it weren't for the H3's broader fender flares the casual spotter might have a tough time telling them apart.
The H3 also shares the H2's off-road prowess. Short overhangs, aggressive approach and departure angles and nine inches of ground clearance help navigate rough terrain. The standard rear axle is a tall 4.56 ratio, and the standard push-button transfer case has a 2.64 crawl ratio. Customers may also opt for an even taller 4:1 transfer case and a full-locking rear axle for extra-slow rock crawling.
The H3 is built on GM's Canyon/Colorado platform, but with a sturdier frame and specially tuned shocks. The H3 also features a two-speed transfer case and electronically controlled four-wheel-drive system with traction control. The H3 also has the option of riding on enormous LT285/75R16 tires, the largest available on any midsize SUV.
The Hummer shares its 3.7L inline five-cylinder engine with its pickup siblings. It was enlarged from 3.5L for 2007, and now generates 242 horsepower and 242 ft-lbs of torque. The standard transmission is a five-speed manual, but Hummer does offer an electronic four-speed automatic transmission.
The standard suspension setup for 2007, the Z85 Handling/Trailering system, should be sufficient for most users. Those looking to test their H3s in the field will be interested in the ZM6 Off-Road Adventure suspension. This option includes a full-locking rear differential, the steeper 4:1 ratio transfer case and special off-road shocks.
The H3X package, new for 2007, features an upgraded Monsoon stereo, eight-way power heated front seats, and chrome accents on the exterior. A touch-screen navigation system is available, and includes the Monsoon stereo.
The WBL Tactical package gives the H3 a body-color grille, black brush guard, and black assist steps, while restricting the exterior paint choices to gray, black, and red.
Addressing complaints that it was underpowered, Hummer's H3 got a larger and more powerful 3.7L inline five-cylinder engine for 2007. An exclusive H3X package is available this year as well, which includes a Monsoon stereo with seven speakers, heated leather power seats, a burly-looking brush guard, assist steps, and chrome wheels.
