On May 16, it was reported that at the technical communication meeting of Great Wall Motor Hi4, the technical director of Great Wall said: "Hi4 has two core values. It achieves the performance of four-wheel drive and energy consumption of two wheel drive. It saves energy wherever it is driven, and achieves the best efficiency under all working conditions. At the same time, it achieves the four-wheel drive experience. The price of two wheel drive is easy to drive wherever it is driven, and it can drive wherever it is going. It realizes the worry free driving in the whole scene."

It is reported that the new Hi4 has been launched on the Haval Xiaolong series recently, achieving landing applications.

Great Wall stated that the all-new Hi4 has broken the technical barrier of traditional series parallel hybrid systems where dual motors can only be two wheel drive, solving the problem of difficult balance in hybrid technology structure complexity, cost control, performance efficiency, and driving experience that has plagued the industry for many years, making the impossible triangle of traditional hybrid "performance, efficiency, and price" a reality. The all-new Hi4 has achieved comprehensive innovation in its underlying configuration, control logic, oil electric power collaboration, intelligent energy management, and other aspects.

The all-new Hi4 breaks the traditional focus of series-parallel hybrid dual motors on the front axle. It adopts a hybrid "new configuration" with three power sources and two axes distribution, allowing the front axle single motor to achieve two functions: power generation and driving under different working conditions. Without increasing car manufacturing costs and user purchasing burden, it achieves a series-parallel four-wheel drive hybrid architecture, expanding user travel scenarios.

In addition, the new Hi4 achieves a new breakthrough in the iTVC intelligent torque vector control system. Through millisecond level monitoring frequency, it can quickly distribute and dynamically adjust the torque of the front and rear axles, which can effectively suppress the slip of the low adhesion road, and understeer or oversteer when cornering, and improve the stability of operation and driving safety; In addition, the electromechanical coupling transmission system achieves coverage of engine direct drive in the near full speed range, meeting the driving needs of users in all scenarios; The all-new Hi4 innovative intelligent energy management system can achieve flexible switching between "3 engines and 9 models" power modes.

In terms of economy, the all-new Hi4 adopts a hybrid "new configuration" of engine+dual motor three power source dual axis distribution, which has the advantages of simple structure and low cost compared to the existing three motor hybrid four-wheel drive system, achieving a "four-wheel drive experience, two wheel drive price". In addition to the price advantage of purchasing a car, the all-new Hi4 also brings cost advantages to users during the driving process.

The all-new Hi4 adopts a series of efficient hardware configurations, including a hybrid dedicated engine with a thermal efficiency of up to 41.5%, a front drive assembly with a transmission efficiency of 98%, and a rear drive assembly with a motor efficiency of 96.5%. Through the combination of intelligent energy management system and iTVC intelligent torque vector control system, it can intelligently switch to a more suitable working mode in different scenarios and conditions, and perform refined power control, achieving a significant reduction in energy consumption of the entire vehicle system, Moreover, the energy recovery model has been further refined to achieve lower fuel consumption performance and lower travel costs for users. The energy consumption performance of the Haval Xiaolong MAX equipped with the new Hi4 technology exceeded expectations, with a WLTC comprehensive fuel consumption of only 1.78L/100km and a WLTC feed fuel consumption as low as 5.5L/100km.

In terms of driving experience, Great Wall Motor, through a new configuration and high-performance power source combination, combined with the iTVC intelligent torque vector control system, can carry out intelligent distribution and dynamic adjustment of front and rear axle torque in real time, which can achieve super acceleration capability in the full speed range. The ability to start and climb on snow slopes is stronger, and the low road surface does not slip or lose control. High speed cornering and high limit driving make it more confident, good continuous cornering and easier to drive, The advantages of driving in six major scenarios, such as getting stuck in a car and stronger relief, allow users to drive anywhere from straight to curved roads, from high to low attachments, and from paved to unpaved roads.
