It is now recognized that the best-performing civilian off-road vehicle in the world is the Hummer of the American AM General Company (AMG for short). The origin of the Humvee dates back 20 years. In 1980, the U.S. Army decided to develop a universal 4-wheel drive light truck. The main goal was to replace the relatively backward multi-model military vehicles at the time and unify multiple models of vehicles into a single model. , in order to reduce procurement costs and simplify spare parts supply and maintenance. In 1981, it invited bids from major car manufacturers in the United States. As a result, AMG won the bid with its long-term experience in producing military vehicles and quickly produced a prototype, named Hmmwv. In 1983, the U.S. military signed a contract with AMG to supply the first batch of 55,000 Hmmwvs. To date, more than 140,000 Hmmwv series vehicles have been produced, 100,000 of which have been equipped by the US military and exported to more than 30 countries and regions. Hmmwv participated in the Gulf "Desert Storm" war and was responsible for transporting personnel and materials. After the war, the U.S. Pentagon released the final report on the war and stated: "The Hmmwv vehicle met all requirements, or exceeded people's requirements... showed excellent cross-country mobility, and its availability exceeded the Army's standards, reaching 90%. "Highly rated.

The first civilian Hmmwv was launched in 1992, named Hummer, transliterated as "Hummer", a very appropriate Chinese name. Hummer immediately became popular with some male car buyers after its launch. Movie superstar Schwarzenegger bought two of them. People in the American basketball and boxing circles also bought Hummer. For a time, Hummer became famous, but few people knew about the "ancestor" Hmmwv.

Hmmwv has a strong appearance and is full of fierceness. It was not designed for civilians, but for the harsh requirements of the U.S. military. The military requires cars to have a service life of up to 12 years when used at almost full capacity. It has unprecedented power performance, handling performance and durability. It can be applied to various special road surfaces and can travel on roads that many sports vehicles cannot travel. It is known as the "King of Off-Road Vehicles" in the industry. It has high ground clearance, large approach and departure angles, wide body, low center of gravity, V8 diesel engine, full-time 4-wheel drive, independent suspension, power steering, etc. There is also a central tire inflation system that allows the driver to change the tire pressure and install run-flat tires. When the tires are deflated, they can still travel at a speed of 48 kilometers per hour and 30 kilometers per hour. While the Hummer has changed in terms of comfort, interior decoration, and power performance compared to the military Hmmwv, the appearance of the model remains the same, making it particularly "alternative" when driving in the city.

The Hummer series has five models, including two-door and four-door hardtop hatchbacks, four-door soft-top hatchbacks, and four-door and two-door pickup trucks. Now, General Motors of the United States has obtained the trademark use and production rights of Hummer from AMG, and has designed the new Hummer H2 with luxurious interior decoration, leather seats, central information display system, GPS satellite navigation system, DVD and audio system, Night vision driving systems, mobile phone holders and laptop computers have been put on the market in early 2002.
