Hummer is an American brand of vehicles, originally a subsidiary of General Motors (GM), that was later acquired by China's Tengzhong Heavy Industrial Machinery in 2009. The brand is best known for its rugged, military-inspired SUVs, particularly the Hummer H1, which was introduced in 1992 and was based on the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV or Humvee) used by the U.S. military. The H1 was followed by the smaller H2 and H3 models, which were based on GM platforms and were designed to appeal to a wider consumer market. Despite their aggressive styling and off-road capability, Hummers faced criticism for their poor fuel efficiency and large environmental footprint, which ultimately led to the brand's downfall. After struggling with declining sales and financial losses, GM discontinued the Hummer brand in 2010, only to revive it again briefly in 2020 as an electric truck.
