Detailed Description
This HOWO NX 400HP 6x4 typically ships with the WP12S400 (or WP12.400 series) engine delivering 400 HP and an approximate displacement around 11.6 L, producing typical peak torque in the ~1700–1900 Nm range (depending on exact engine tune). Matched to a heavy-duty HW19710 transmission and HC16 dual rear axles (ratio ~4.42), the drivetrain is optimized for heavy loads and stable high-speed cruising. Advantages: robust powertrain, high torque for hill climbs and heavy trailers, and industrial-grade gearbox.
The chassis comes with a reinforced double-layer frame option, multi-leaf heavy springs (front/rear strengthened), ABS (4S/4M) and choices of large fuel tanks (single 400L or dual 400L+400L) for extended range between refuels. Cab options include the modern HW76 front-face cab with air conditioning and optional comfort seats; tire options such as 12.00R20 or 295/80R22.5 are available per spec. Advantages: long range (large fuel capacity), heavy-duty frame and suspension for high payloads, and flexible factory/aftermarket options to fit fleet needs.
