Fast science and technology news on October 22nd, today, Great Wall held the Great Wall TK autumn technical conference, at the meeting, Great Wall officially released the vertical dual-motor hybrid architecture Hi4-Z cross-country platform.
According to Gu Yukun of Great Wall Automobile, the Hi4-Z cross-country platform meets the needs of users who yearn for cross-country and attach importance to the daily car experience.
in addition to daily commuting in the urban area, it can also cross the desert and camp outdoors.
, , Gu Yukun said that tanks only play bright cards, not edge balls, and in strong cross-country scenarios, Hi4-T is the best solution for cross-country new energy, while in pan-cross-country, Hi4-Z is definitely at the top.
Thanks to the integrated design of three-speed DHT and stepless variable speed, Hi4-Z can achieve the first power preservation capacity in the industry in high-load crossing scenarios, with zero acceleration of 4 seconds and a maximum comprehensive power of 715kW.
The Hi4-Z cross-country platform is positioned as an ultra-long-range cross-country platform with a pure electric range of more than 200km.
Because 85% of mixed users have a city travel mileage of less than 200km a week, the goal of Hi4-Z is to make the vast majority of users work in cities with zero fuel consumption and recharge only once a week.
To this end, they increased the battery of the general hybrid car from 3 to 40 degrees to 60 degrees.
during this period, the Great Wall successfully highly integrated the structure of the stepless transmission with the motor system, creating the world’s first shortest longitudinal three-gear hybrid model, successfully stuffing the battery capacity of a Tesla into the girder of the tank.
, in addition, large-capacity batteries have higher requirements for fast charging.
The Hi4-Z off-road platform is equipped with the fastest fast charging battery in the plug-in field, with a maximum charging power of 163kW, more than 60% higher than other off-road vehicles, high-speed fast charging for 15 minutes, and an increase of 120km in pure electric life.
In the case of
, the Hi4-Z engine achieves the highest thermal efficiency in the field of off-road vehicles while achieving high power and high torque through Miller cycle low-voltage EGR energy-saving technology.
The deep integration of 
, three-gear DHT and infinitely variable speed allows the engine to drive directly in the full speed range, reducing the loss of power transmission.
Different from the series-based structure in the market, power can only be generated by generators under feed.
When driving in the power supply city, the fuel consumption of Hi4-Z is 100 kilometers lower than that of the same class of competitive products.
when driving at high speed, Hi4-Z locks the rear axle through the stepless transmission mechanism and disconnects the front axle with efficient direct drive.
Compared with the same class of competitors, the fuel consumption of high speed is reduced by 1.
3L/ 100 kilometers.
In terms of power, the Hi4-Z platform is equipped with a high-performance engine and a front and rear high-power motor system, with a comprehensive power of up to 715kW.
When accelerating at full speed, the three power sources generate force at the same time, zero acceleration for 4 seconds.
Even in the case of a power deficit, a 5-second acceleration can be achieved.
, 
, in addition, according to the Great Wall, the third gear DHT structure of the Hi4-Z, the second gear is for daily use, the third gear is used for high-speed cruising, and the first gear is used for low-speed all-wheel drive.
