Hummer (stylized as HUMMER) is 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 from AM General and marketed three vehicles: the original Hummer H1, based on the military Humvee, as well as the new H2 and H3 models that were based on smaller, civilian-market GM platforms. The manufacturer of the Hummer H1 and H2, AM General, lost their bid to build the HMMWV's replacement for the U.S. military in 2015, to Oshkosh Corporation.
