Hummer was a brand of trucks and SUVs, first marketed in 1992 when AM General began selling a civilian version of the M998 Humvee. In 1998, General Motors (GM) purchased the brand name and marketed three vehicles: the original Hummer H1, based on the military Humvee, as well as the H2 and H3 models that were based on smaller, civilian-market GM platforms.
Criticism of Hummers mirrors the criticism of SUVs in general, but to a higher degree. Specific criticisms of Hummers include:
Hummers (specifically the H1 and H2) are significantly bigger than other SUVs; this can cause problems parking, driving and fitting in a garage. Their large size may also pose a serious threat to smaller vehicles.
Poor fuel economy
Even compared to other heavy passenger vehicles, Hummers without the diesel engine options have very poor fuel economy. Because the H2 is built to the over-8500-lb GVW class, its fuel economy is neither published by the U.S. EPA nor counted toward Corporate Average Fuel Economy. For example, H2 in one engine configuration averages an estimated 14 mpg-US (17 L/100 km; 17 mpg-imp) on the highway and 10 mpg-US(24 L/100 km; 12 mpg-imp) in the city. It has a curb weight of around 6,400 lb (2,900 kg).
Crash data for Hummers is less complete than for other SUVs. As a Class 3 truck, the Hummer is exempt from many DOT safety regulations. The H1 lacks standard safety features, including child safety locks, child seat tethers, side air bags, and stability control. Large blind spots make parking difficult and possibly dangerous.
A one-year study, conducted by a firm that provides statistical information to insurance companies, found that drivers of H2 and H3 Hummers receive about five times as many traffic tickets as the national average for all vehicles (standardized based on the number of violations per 100,000 miles driven).
