The all-new hybrid architecture Hi4 represents the world’s pioneering intelligent 4WD electric hybrid technology. Based on the concept of “more fuel-efficient, longer-range, and safer”, Great Wall Motors has created a “top-tier” hybrid technology with the innovative configuration of series-parallel electric 4WD featuring dual motors on the front and rear axles.
Through the dynamic switching of 3-engine 9-mode and the intelligent energy management system, the all-new Hi4 truly achieves “4WD experience at 2WD price, 4WD performance with 2WD energy consumption”, realizing “optimal efficiency in all working conditions and worry-free driving in all scenarios”.
Key advantages：
