Hummer was basically a Military vehicle M998 Humvee. In 1992, AM General made civilian version of Humvee. General Motors (GM) purchased AM General in the year 1998.GM marketed three vehicles. The first one is based on Humvee, the original Hummer named H1. The other models H2 and H3 are based on civilian market. GM was responsible for branding and marketing of the vehicles manufacture by AM General.
During the 2009 bankruptcy, Hummer was retained by GM. A Chinese manufacturer was interested in acquiring the company and finally dropped acquisition plans in 2010. Since inventories were depleted and dealers were closing, GM has finally stopped the production in 2010. There were many criticisms because of its design and built up. The first criticism was regarding size. Because of its size there were parking problems, driving and fitting in a garage. Without diesel engine variant, hummer had a very poor fuel economy increasing the running costs. It even lacked some of basic safety features as it was originally designed for military use.
