This heavy-duty 420HP Tractor Truck unit belongs to the SINOTRUK HOWO brand, designed specifically for high-efficiency express transportation scenarios. It is configured with a roof fairing (aerodynamic deflector) that effectively reduces wind resistance during high-speed operation, thereby optimizing fuel efficiency and enhancing long-haul performance.

Under the cab, it features a robust powertrain: a 420hp engine with a displacement of over 8 liters, delivering a maximum torque range of 1500-2000Nm—providing sufficient power reserve for handling heavy loads (gross vehicle weight: 10001-15000kg) even on complex road conditions. The vehicle complies with Euro 2 emission standards and adopts a 6×4 drive system, ensuring strong traction and stability for long-distance logistics tasks.

In terms of structure and components, the 420HP Tractor Truck measures 6.8m × 2.5m × 3.1m, offering a balanced combination of maneuverability and loading compatibility. It is equipped with a HW76/HW79 cab (supporting both left-hand and right-hand driving layouts for global market adaptability), 12.00R20 heavy-duty tires for enhanced load-bearing capacity, and an HC16 rear axle that ensures reliable power transmission. Whether for inter-city express freight or regional bulk cargo hauling, this HOWO 6×4 tractor with a roof fairing stands out as a durable, high-performance solution for modern logistics operations.
