Hummer H3 Off-Road Rubicon Trail

Hummer H3 is the smallest of the three Hummer models, and though the H3 concept car was a pickup truck, the final vehicle is a conventional SUV. Its GMT345 platform is based on the GMT355 which underpins the Chevrolet Colorado and GMC Canyon pickup trucks. The H3 is built at GM's Shreveport, Louisiana factory. Export versions will also be produced at the General Motors South Africa facility in Struandale, Port Elizabeth, South Africa.

H3 uses the 3.7 L (3653 cc) Atlas straight-5 engine, the same engine that is used in the Chevrolet Colorado and GMC Canyon pickup trucks. This 20-valve DOHC unit produces 242 hp (180 kW) at 5600 rpm and 242 ft�lbf (327 N�m) at 2800 rpm. It is available with a 5-speed manual or 4-speed automatic transmission that includes GM's Stabilitrak vehicle stability control.

For 2007, H3 receives a new engine: the Vortec 3.7L I-5 with dual overhead cams and variable valve timing. This inline five-cylinder engine offers an excellent combination of power and efficiency, delivering 242 horsepower (180 kW) at 5600 rpm* and 242 lb.-ft. of torque (328 Nm) at 4600 rpm.
