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.

New Configuration

Hybrid with three power sources and dual-axis distribution

Dual-motor dual-axis distribution, close to 50:50, achieves free transfer of torque between axles in the full range of 0-100, capable of easily coping with daily travel and complex road conditions.

New Breakthrough

iTVC intelligent torque vector control system

Improves vehicle stability, comfort, and safety, with a maximum acceleration increase of up to 40% in the full speed range.

New Level

Electromechanical coupling transmission system

The lifespan of key components that cooperate with the engine and dual motors can be extended by more than 1.3 times.

3 Engines and 9 Modes, Adding 3 New Modes

Seamless adaptive switching, torque request <10ms, 1s = 100 data interactions
Pure electric four-wheel drive, parallel four-wheel drive, dual-axis energy recovery
