<Tr> <Th> Curb weight </Th> <Td> 4,700--4,900 lb (2,100--2,200 kg) </Td> </Tr> <P> The Hummer H3 is a sport utility vehicle / off - road vehicle from Hummer that was produced from 2005 to 2010 . Introduced for the 2006 model year, it was based on a highly modified GMT355 underpinning the Chevrolet Colorado / GMC Canyon compact pickup trucks that were also built at GM's Shreveport Operations in Shreveport, Louisiana and the Port Elizabeth plant in South Africa . The H3 was the smallest among the Hummer models, and the only one to be built by General Motors . It was available either as a traditional midsize SUV or as a midsize pickup known as the H3T . </P> <P> The H3 was launched with a 3.5 liter straight - 5 cylinder L52 engine that produced 220 hp (160 kW) and 225 lbf ⋅ ft (305 N ⋅ m) of torque and was mated to a standard five - speed Aisin AR5 manual transmission or an optional Hydra - Matic 4L60 - E four - speed automatic transmission . In 2007 this engine was replaced by the 3.7 liter LLR that produced 242 hp (180 kW) and 242 lbf ⋅ ft (328 N ⋅ m) of torque, figures that were revised in 2009 to 239 hp (178 kW) and 241 lbf ⋅ ft (327 N ⋅ m). Under revised EPA testing standards when equipped with either transmission this straight - 5 engine achieved 14 mpg (17 l / 100 km) in the city and 18 mpg (13 l / 100 km) on the highway with a combined average of 15 mpg (16 l / 100 km). Available solely with the automatic transmission, a 5.3 liter LH8 V8 engine producing 300 hp (220 kW) and 320 lbf ⋅ ft (430 N ⋅ m) of torque was added in 2008 for the Alpha model . The V8 version had lower fuel economy, estimated at 13 mpg (18 l / 100 km) in the city, 16 mpg (15 l / 100 km) on the highway, with a combined average of 14 mpg (17 l / 100 km). </P> <P> The H3 featured a two - speed, electronically controlled full - time four - wheel drive system that made it for both on - road and off - road driving . Electronic locking front and rear differentials were optional . Like the Hummer H2, the H3 can ford 27 inches (690 mm) of water (tested in depths up to 34 in or 864 mm) at a speed of 5 mph (8.0 km / h) and 20 in (508 mm) of water at a speed of 20 mph (32 km / h). Standard ground clearance with the 31 inch tires measured at 9.7 in (246 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 (406 mm) vertical wall and negotiate grades of 60% and side slopes of 40% . Front and rear recovery hooks were standard, with an optional trailer hitch and wiring harness . The H3 features an intelligent traction control similar to what modern Land Rover or Toyota off road vehicles have, which can use the brakes independently to stop wheelspin and improve traction while being adjusted automatically to the road conditions with no driver action . It is also equipped with Stabilitrak stability control, and intelligent ABS with variable brake force distribution assist . </P>
