What is the Hummer H2's gas mileage?

The Hummer H2's fuel economy ranks as one of the worst of any consumer automobile, with reviewers reporting the vehicle gets around 8-10 miles per gallon. Poor maintenance can degrade the mileage even further, making the Hummer an extremely costly vehicle to drive.

Because of the H2's gross vehicle weight rating, the manufacturer is not required to publish official fuel economy figures for the vehicle. Testing under various driving conditions has produced fuel economy measurements as high as 12.4 miles per gallon under ideal circumstances, considerably below that of most passenger vehicles and well below the increasing Corporate Average Fuel Economy, or CAFE, standards put in place by the government.
