HOWO 7 6×4 Tractor Truck

The Golden Power Combination: Whether equipped with the market-renowned D10 and D12 series engines developed in-house by Sinotruk in earlier models, or the high-end Weichai powertrain fully adopted in later upgraded models, the HOWO 7 delivers ample horsepower. Its maximum torque is available across a wide RPM range and starts at a low RPM, meaning the vehicle can generate high torque even at low engine speeds.
Excellent Acceleration and Hill Climbing: These power characteristics give the vehicle exceptional heavy-load acceleration and hill-climbing capabilities. In harsh operating conditions such as construction sites, mines, riverbeds, or muddy roads, the vehicle is unlikely to stall, and power is readily available, allowing it to easily handle various complex low-speed scenarios.
In-House Developed Transmission: Paired with the powerful engine is Sinotruk’s in-house developed classic HW series multi-speed transmission (such as the HW19712 and HW25712). It features clear shift logic and high transmission efficiency. Some high-end models are further equipped with the S-AMT seamless shifting system, which significantly reduces driver fatigue and ensures precise, smooth power delivery every time.
