There are at least three Chinese automobile manufacturers building Humvee copies. Two of the Humvee copies rely heavily on copied U.S.-made parts including chassis, gear box, and diesel engine in the past. Currently, these companies have the capability of making indigenous parts for these Humvee-like vehicles.
During the 1988 Beijing Defence Exhibition, AM General presented a M998 4x4 to the People's Liberation Army. The PLA didn't show much interest to the vehicle before the events of Operation Desert Storm, which made them interested in studying the vehicle. The Chinese petroleum industry purchased Hummers through American commercial sources in the mid-1990s. This provided the Chinese auto makers with an opportunity to examine the vehicle closely and provided an opportunity for reverse engineering. Later in 2003, the EQ2050 made its debut in a car show after a prototype was made in 2002. The vehicle became the preferred candidate in 2004 with 57 vehicles sent to the PLA for trials from 2004 to 2006. The first 100 EQ2050s were made with American-made parts. It passed design trials in 2006. EQ2050s were then delivered to PLA special forces unit in the Guangzhou Military Region. It's known as Mengshi in Chinese.
The EQ2050 is based on an imported AM General Hummer H1 chassis. The DFM EQ2050 is powered by a Dongfeng license-built Cummins EQB150-20 110 kW/2,700R turbo-charged diesel, but it can also be fitted with the U.S.-made V8 diesel originally designed for Humvee. Both vehicles have a 5-speed gear box and a 2-speed transfer box. They are both four-wheel drive with independent suspensions and central inflating system. The EQ2050 also has re-designed lights and radiator to make it look different from the original Humvee. DFM has cooperated with AM General Motors on getting American-made parts for the first EQ2050s made.
A variant of the EQ2050 called the EQ2058 was made for military purposes, which has an armored body. A civilian version of the EQ2050 is being made by DFM, which will use petrol engines instead of diesel engines.
While the EQ2050 was adopted by the PLA, it was also adopted by People's Armed Police Fire Fighting brigades and by Chinese Public Security Police forces. It is called the Hanma, an approximation of the Chinese pronunciation of Hummer.
