The army requires the service life of automobiles to be as long as 12 years under almost full load. Unprecedented power performance, maneuverability and durability, it can be applied to all kinds of special roads, and it can drive many roads that sports cars can't drive, and it is praised as the "king of off-road vehicles" by the industry. High ground clearance, large angle approach angle and departure angle, wide body, low center of gravity, V8 diesel engine, full-time four-wheel drive, independent suspension, power steering, etc. There is also a central tire inflation system where the driver can change the tire pressure and assemble the flat tire. When the tire is deflated, it can still travel 30 kilometers at a speed of 48 kilometers per hour. However, Hummer is better than military Hmmwv in comfort, interior and dynamic performance, but its appearance remains unchanged, making it a special "substitute" for driving in cities.
There are five types of Hummer series, including two-door and four-door hardtop hatchbacks, four-door hood hatchbacks, four-door and two-door pickup trucks. Now, American General Motors Company has obtained the trademark right and production right of Hummer from AMG Company, and designed a brand-new Hummer H2 with luxurious interior, leather seat, central information display system, GPS satellite navigation system, DVD and audio system, night vision driving system, mobile phone stand and notebook computer, which has been put on the market in early 2002.
