2010 HUMMER H3 Review

Bye-bye big boy

Reviewed by Automotive on

In a Nutshell
The 2010 Hummer H3 is available as a midsize sport utility vehicle (SUV) or truck (SUT) in four trim levels: Base Sport Utility, Alpha Sport Utility, Adventure Sport Utility, and Luxury Sport Utility. Equipped with full-time four-wheel drive and a two-speed transfer case, the Hummer 3 base engine is a 3.7-liter inline five-cylinder mated to a standard five-speed manual transmission or optional four-speed automatic. The Alpha trim has a 5.3-liter V-8 engine paired to a four-speed automatic transmission.

Acceleration is lackluster due a 5,000-pound weight, and the maximum towing capacity is rated at only 4,500 pounds. EPA estimated fuel economy is poor, with a 14 mpg city / 18 mpg highway rating. Safety ratings are not that great, either, earning only "Acceptable" in two categories of crash testing.

New for 2010

For 2010, the Hummer H3 gets only a few changes, including silver on the front bumper, a flexible-fuel capability, and the Appearance package.


Engines: 3.7L I-5, 5.3L V-8
