SINOTRUK 6X4 HOWO A7 420HP Tractor Truck for Sale
This SINOTRUCK 6X4 HOWO A7 420HP Tractor Truck was among the first Chinese-brand models to widely adopt an intelligent automated manual transmission (AMT) at the time, equipped with the HW19710 series AMT. This system intelligently selects the optimal gear based on load and road conditions, fully freeing the driver while eliminating operational inconsistencies and power interruptions caused by manual shifting. It serves as the “intelligent control core” for improving average speed, reducing fuel consumption, and easing driver fatigue.
