The HUMMER H3 SUV is a vehicle from General Motors' Hummer division introduced in 2006 and based on the GMT355 that underpins the Chevrolet Colorado and GMC Canyon compact pickup trucks. Currently produced at GM's Shreveport, Louisiana factory and the Port Elizabeth plant in South Africa the H3 is the smallest of the Hummer models, and the first to be built by GM. It is available either as a traditional midsize SUV or as a midsize pickup known as the H3T.

H3 in the International Market

In 2007 GM South Africa launched their first Hummer production facility in Port Elizabeth, this move introduced the Hummer brand to the South African market and also somewhat lightened the load of the Shreveport factory in Louisiana. The plant manufactures only the Hummer H3, and builds for the South African market as well as the Asian market and European continent Particually In England.The Nearest Hummer Dealership In the North east of England is located just outside Newcastle upon tyne near the Tyne Tunnel.

Powertrains

The H3 was launched with a 3.5 liter straight-5 cylinder L52 engine that produced 220 hp (160 kW) and 225 ft·lbf (305 N·m) of torque and was mated to a standard five-speed manual transmission or an optional Hydra-Matic 4L60-E four-speed automatic transmission. In 2007 this engine was replaced by 3.7 liter LLR that produced 242 hp (180 kW) and 242 ft·lbf (328 N·m) of torque, figures that were revised in 2009 to 239 hp (178 kW) and 241 ft·lbf (327 N·m). Under revised EPA testing standards when equipped with either transmission this straight-5 engine achieves 14 mpg_-US (17 l/100 km) in the city and 18 mpg_-US (13 l/100 km) on the highway with a combined average of 15 mpg_-US (16 l/100 km). Available solely with the automatic transmission, a 5.3 liter LH8 V8 producing 300 hp (220 kW) and 320 ft·lbf (430 N·m) of torque was added in 2008 for the Alpha model of the H3 and returns slightly lower fuel economy estimated at 13 mpg_-US (18 l/100 km) in the city, 16 mpg_-US (15 l/100 km) on the highway, with a combined average of 14 mpg_-US (17 l/100 km).^[1]

In 2012, the H3 and H3T are expected to be facelifted along with the total redesign of their Colorado/Canyon siblings. The 281 hp 3.6 L LLT V6 found in the Chevrolet Traverse is expected to replace the current 3.7 Atlas I5 model with the promise of better fuel economy. The 5.3 Vortec V8 is still expected to stay in production.

Plug-in hybrid

An April 2009 Engadget column^[2] reported that Raser Technologies and FEV had built a prototype plug-in hybrid H3 that could achieve 100 MPG given enough mains power. This vehicle, known later as the Electric Hummer H3, was then showcased by California State Governor Arnold Schwarzenegger at a press conference at the State Capitol in Sacramento as part of a campaign to promote greener vehicles.^[3]

Capabilities

The H3 features a two-speed, electronically controlled full-time four-wheel drive system that is suitable for both on-road and off-road driving in all conditions, with electronic locking front and rear differentials optionally available. Like its larger sibling the Hummer H2, the H3 can ford 24 inches (610 mm) of water (tested in depths up to 31 in/790 mm) at a speed of 5 miles per hour (8.0 km/h) and 16 inches (410 mm) of water at a speed of 20 miles per hour (32 km/h). Standard ground clearance is measured at 9.7 inches (250 mm) while the approach, departure, and breakover angles are measured at 37.4°, 34.7°, and 22.1° respectively, allowing the H3 to scale a 16-inch (410 mm) vertical wall and negotiate grades of 60% and side slopes of 40%. Though fore and aft recovery hooks are standard, a trailer hitch and wiring harness are optional.

Maximum towing capacities are 3,000 pounds (1,400 kg) for the straight-5 with manual transmission, 4,500 pounds (2,000 kg) for the straight-5 with automatic transmission, and 6,000 pounds (2,700 kg) for the V8 with automatic transmission. Cargo volume with the second-row seats in the upright position is 25.0 cubic feet (0.71 m³), which expands to a maximum of 62.8 cubic feet (1.78 m³) when the seats are folded down. V8 models feature the lightest maximum payload capacity of just over 1,100 pounds (500 kg) while straight-5, manual transmission models allow the greatest payload at 1,300 pounds (590 kg).

Safety

Electronic stability control, anti-lock four-wheel disc brakes, brake-controlled traction control, LATCH child-seat anchors, and tire-pressure monitoring are all standard features on the H3. Side-curtain airbags were optional until 2008 when they were made standard across. The H3 is rated Acceptable, the second highest rating, by the Insurance Institute for Highway Safety in both frontal offset and side-impact crashes (with side airbags) and Poor, the lowest rating, for rear-crash protection/head restraints.^[4]

The NHTSA gives the 2008 H3 the following scores:

H3T

See Hummer H3T

The Hummer H3T was a concept vehicle from Hummer - mainly used as a media diversion from the Hummer H3 which was to be released in mid 2005. The Hummer H3T production model was shown at the 2008 Chicago Auto Show, with sales set to begin in August 2008 as a 2009 model. The H3T is based on the H3 model, and is a crew cab pickup truck. With a 5-foot (1.5 m) bed, the H3T lands between mid-size and full-size truck classes.
