The SX2190 7 tonne 6x6 truck was developed from the Austrian Steyr-Daimler-Puch (now part of General Dynamics European Land Combat Systems) Steyr 90 truck technology. China first approached Western countries in the late 1970s to see heavy duty truck technology, and a co-production agreement was signed with Austria in the 1980s. The truck entered the PLA service in the late 1990s to replace its ageing Huanghe JN252 and Hongyan CQ261.
The SX2190 truck adopts the “cab over engine” (COE) layout. The forward control cab has two doors with a hard top to accommodate four crews. The rear cargo body is provided with a drop tailgate and sides, and removable bows with canvas cover. A single spare wheel is mounted vertically behind the crew cab, adjacent to a stowage space between the cab and rear cargo body. This space could be used to accommodate a repairing tools box and other loading/unloading equipment. A hydraulic winch (optional) unwinds to both front and rear with a pulling capacity of 10,000kg.

The truck is powered by an in-line, 6-cylinder, 4-stroke, liquid-cooled, turbo-charged Steyr WD615.50 diesel, with a total displacement of 9.762 litres, providing 206kW at 2,400r/min. The RT11609 gearbox has nine forward and two reverse gears. The vehicle is fitted with power assisted steering as standard.
The SX2190 has been mainly deployed by the artillery troops for artillery gun hauling, and engineering troops for heavy equipment transport role. As well as the standard truck version, it is also available in a range of variants, including the SX2190BQ (short cab), SX2190D (with winch), SX2190E (long wheelbase), and SX4260 (tractor/semi-trailer).
