Leading Chinese automaker GWM has unveiled its latest hybrid technology platform Hi4  at its NEV Day, featuring an advanced EV-based powertrain technology that Efficiency optimized under all road conditions and driving scenarios.

GWM has continuously deepened its new concept of energy and intelligence, and has a complete industrial vehicle chain, which includes hybrid architecture, energy batteries, hydrogen energy, electric propulsion technology, intelligent cabin, intelligent driving and intelligent chassis.

The Hi4 platform has two powertrains with a maximum system output of 340 kW, which covers vehicle models from classes A to C. The e-hybrid powertrain achieves an industry-leading thermal efficiency of 41.5% made possible by its advanced combustion system, high-pressure direct injection and low-pressure exhaust gas recirculation technology. In addition, the intelligent energy management and control strategies of the Hi4 platform ensure optimal operational efficiency, improving vehicle energy savings by around 8% compared to traditional energy management.

The Hi4 platform also offers a range of over 100 km in pure electric mode. This is thanks to the powerful battery, which is equipped with advanced lithium-ion technology and thus ensures a long service life. High-voltage charging technology and intelligent charging management system enable the fast charger to be 97% energy efficient, and it takes less than 30 minutes to charge from 30% to 80% under normal ambient temperature.

The Hi4 platform also features three new breakthroughs in hybrid technology: a new E-Hybrid architecture to expand the user's driving scenarios, a new dynamic control technology that relies on high-precision millisecond sampling, and a new, more powerful electromechanical coupling transmission system .

The new E-Hybrid architecture uses a hybrid "new design" with three power sources and two-axle distribution. It uses two electric motors with a serial parallel electric hybrid architecture for 4WD vehicles. This expands the user's driving scenarios and is suitable thus for both city and off-road trips.

GWM's iTVC (intelligent Torque Vectoring Control) system is a new dynamic control technology based on high-precision millisecond sensing of vehicle speed through engine rotation. GWM's iTVC distributes and adjusts torque between the front and rear axles in milliseconds, effectively preventing slippage on low-friction road surfaces and improving steering stability and driving safety when cornering.

The electromechanical clutch system is an innovative design of two electromechanical clutch units that covers almost the entire engine speed range and meets the driving needs of users in all scenarios.

"The Hi4 platform offers strong performance and lower fuel consumption, and thanks to the innovative features of its dual motors and dual-axis control, it also improves steering stability and driving safety when cornering," said the Technical Manager for Propulsion Systems.

GWM's Hi4 platform will revolutionize the hybrid SUV market by offering customers an unprecedented combination of performance, safety and efficiency. This makes them the smart choice for riders who demand the best.
