About Hummer H3

Hummer H3 is a sport utility vehicle (SUV) or off-road vehicle manufactured by General Motors but marked by Hummer from 2005 to 2010. The first Hummer H3 was introduced in 2005 as a 2006 model year vehicle. It was built at the GMT355 platform at which Chevrolet Colorado and GMC Canyon compact pickup trucks were produced as well. The Hummer H3 is the smallest model among all Hummer models. But it did well in safety and had received Acceptable rating from Insurance Institute for Highway Safety (IIHS).
Hummer H3 featured a two-speed, electronically controlled full-time four-wheel drive system, which made it possess powerful both on-road and off-road capacities. Standard Hummer H3 was equipped with electronic stability control, anti-lock four-wheel disc brakes, brake-controlled traction control, LATCH child-seat anchors, and tire-pressure monitoring. Hummer H3 was first powered by a 3.5 L L52 straight 5-cylinder engine that could produce 220 hp and 225 pound feet of torque and then a 3.7 L LLR straight 5-cylinder engine that could produce 242 hp and 242 pound-feet of torque replaced it. Both engines were mated to a standard 5-speed manual transmission or an optional Hydra-Matic 4L60-E 4-speed automatic transmission.
