Hummer H3

The Hummer H3 is a vehicle from the General Motors Hummer family, introduced in 2005. 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. Its platform is based on the GMT355, but the vehicle actually uses a GMT345, though it is still similar to the Chevrolet Colorado pickup truck and its relatives.

Since it is rated at less than 8500 lb (GVWR), Hummer is required to provide official fuel economy ratings. It is rated at 16 mpg in the city cycle with both transmissions and 19 mpg with the automatic or 20 mpg with the manual on the highway. While the Hummer H2 will ford through 16 inches of water, the H3 will handle 24 inches of water. The H3 is the only vehicle in its class to have a 2 speed transfer case standard.

A review in the Boston Globe referred to its engine as having only "modest" horsepower and torque, having "reasonable" performance but "a bit sluggish passing uphill," and "certainly not for heavy towing or serious off-road driving." {{ref|globe}}
