On March 27, Kuai Technology reported that Great Wall Motors officially launched its heavy truck Hi4-G hybrid technology.

Great Wall Motors stated that during the development of the Hi4-G hybrid, the technical team has been stationed at the front line of user transportation for years, following drivers to run their routes and accumulating 1,026 sets of scenario data. This data has transformed users' core demands for fuel efficiency, power, and scenario adaptability into achievable technical solutions.

Great Wall Commercial Vehicle CTO Sun Yu announced on-site that, based on user test data verified over 5 million kilometers,The Great Wall Hi4-G heavy truck's fuel consumption on flat highways is reduced by 3-4 liters compared to traditional diesel heavy trucks.

The fuel consumption for plain express delivery is as low as 19.9L/100km; the fuel consumption reduction for cold chain transportation in mountainous areas exceeds 30%.The comprehensive fuel-saving rate for complex routes reaches 15%-25%.

The certification tests conducted according to CHTC-TT national conditions show that.The Great Wall heavy-duty truck equipped with the Hi4-G super hybrid system is the first heavy-duty truck in the country with a comprehensive fuel consumption of less than 30L/100km.

The comprehensive fuel consumption is only 29.7L/100km, which is a 17% reduction compared to the national Stage IV standard (35.8L/100km), leading the industry in working condition fuel consumption.

It is reported that...The Great Wall Heavy-Duty Truck Hi4-G Super Hybrid System is specifically designed for heavy-duty trunk logistics, integrating three engines, eight-speed transmission, and ten-mode core technology.

Combining the Cummins 13L high-efficiency engine to achieve efficient collaboration between diesel and electric power, with a total horsepower exceeding 1000.

Industry-first three-engine intelligent power architecture (P2 + P2.5 dual motors + diesel engine), independent control of dual motors, uphill assist, downhill energy recovery, and 15% range enhancement in mountainous scenarios.

The intelligent domain control system can analyze load, road conditions, and time requirements in real time, automatically switching between ten driving modes.

In addition, Great Wall's heavy-duty trucks feature an all-in-one domain controller developed in-house, which integrates functions such as battery management and drive control, supports OTA remote upgrades, and further enhances system response speed and reliability.

The 30C high-rate battery supports fast charging and discharging, with a cycle life exceeding 1 million kilometers. The engine's B10 lifespan reaches 1.8 million kilometers, and the oil change interval is extended to 200,000 kilometers. The lifespan of the clutch and brake pads is doubled, reducing maintenance costs and providing users with reliable performance across all scenarios.
