The Hummer H3 is a new vehicle from the General Motors Hummer family. The Hummer H3 is the smallest of the three Hummer models, and more in-line with standard SUVs. The H3 concept was originally for a pickup truck, but the final vehicle is a conventional SUV. It shares the GMT355 platform with the Chevrolet Colorado pickup truck and similar vehicles.
The H3 uses the 3.5 L (3464 cc) Atlas straight-5 engine. This 20-valve DOHC unit produces 220 hp (164 kW) at 5600 rpm and 225 ft.lbf (305 Nm) at 2800 rpm. It is available with a 5-speed manual or 4-speed automatic transmission. Its 111.9 in wheelbase is 1.1 in shorter than the GMT360 SUVs it is related to. It includes an electronically-controlled dual-speed transfer case and electronic locking differential.
Since it is rated at less than 8500 lb (GVWR ), Hummer is required to provide official fuel economy ratings. It is rated at 15 mpg in the city cycle and 18 mpg on the highway.
The H3 is built at GM's Shreveport, Louisiana factory. Export versions will also be produced at a GM facility in Struandale, Port Elizabeth, South Africa.
