GWM NEW ENERGY
Hi4
The new intelligent 4WD electric hybrid technology, Hi4 truly realizes "performance of four-wheel drive and the energy consumption of two-wheel drive", achieving "optimal efficiency in all working conditions, worry-free driving in all scenarios".
H(Hybrid)
i(Intelligent)
4(4WD)
Hi4, H (Hybrid) , I (Intelligent), 4 (4WD), the new hybrid architecture Hi4 represents the world's first intelligent control four-wheel drive hybrid technology. Based on the concept of "go with more", GWM uses the innovative configuration of dual-motor series-parallel electric four-wheel drive on the front and rear axles to create a "ceiling-level" hybrid technology.
The Hi4 achieves the "four-wheel drive experience, two-wheel drive price, four-wheel drive performance, two-wheel drive energy consumption" through the dynamic switching and intelligent energy management system of 3 engines and 9 modes, achieving "optimal efficiency in all operating conditions and worry-free driving in all scenarios".
Three Innovations
The new intelligent four-wheel drive hybrid technology Hi4 achieves three major innovations, namely, the hybrid "new configuration" with three power sources and dual-axis distribution, the "new breakthrough" of the iTVC intelligent torque vector control system, and the "new height" of the electromechanical coupling transmission system.
