On December 4, the off-line ceremony of Great Wall Motors' "Bee Mang Goes Nest to the Future" 3.0T 9AT super powertrain was successfully held in Yongchuan, Chongqing. The successful off-line ceremony means that the 3.0T 9AT super powertrain has officially achieved global mass production, which strongly verifies Great Wall Motors' hard-core capabilities in the field of core power technology.
As China’s first fully self-developed high-end powertrain, Great Wall Motors’ 3.0T 9AT breaks the technical barriers of joint ventures, achieves comprehensive performance leaps with many advanced innovative technologies, and is comparable to the top international levels. It can be called a traditional powertrain A milestone product in the field, its mass production off the production line marks the official entry of Chinese automobile brands into the high-end product market, and it has an epoch-making industry status and value that will shape the future. The first model of this powertrain is the Tank 500, which was recently released for pre-sale at the Guangzhou Auto Show.

The "king" of 550N·m peak torque and 38.5 thermal efficiency power officially debuts
In the context of dual carbon goals, industry companies have turned to new energy tracks or chosen to reduce displacement. In the traditional fuel field, High-end power has become a rarity in the market. Currently, only a few luxury brands have related products in the market, while Chinese brands are almost at a blank stage. Great Wall Motors bucked the trend and launched the 3.0T 9AT super powertrain, which is composed of the Great Wall Motors 6Z30 engine and the first domestic V6 9-speed hydraulic automatic transmission. It has three major characteristics: powerful, efficient and reliable. It is powerful with high energy and low consumption. The advantages solve the contradiction between large displacement and low emissions.

The Great Wall Motors 6Z30? 3.0T engine that rolled off the production line this time can be called the king in the field of traditional power. It has a displacement of 3.0L and adopts a V-type The 6-cylinder layout, with the support of hard-core technologies such as dual injection and dual VGT supercharging, the maximum power and torque are as high as 260kW and 500N·m respectively. At the same time, using a 48V light-hybrid BSG motor, the peak torque can be further increased to 550N·m. The engine A powerful torque of 340N·m can be unleashed at a low speed of 1000r/min, and the maximum climbing ratio reaches 57.2, enabling 100-degree climbing, allowing the vehicle to calmly handle extreme off-road scenes such as climbing.
Wang Yifu, product director of Honeycomb Power 3.0T engine of Great Wall Motors, explains the 6Z30 3.0T engine
In terms of reducing energy consumption, the performance of Great Wall Motors 6Z30 3.0T engine is still eye-catching. It passes the Miller cycle , full map oil pump and a series of advanced technologies to raise the upper limit of thermal efficiency, reduce mechanical losses, and ultimately achieve a high thermal efficiency of 38.5, which is extremely rare in the 3.0L displacement level. The Great Wall Motors 6Z30 3.0T engine not only achieves extremely high single-point thermal efficiency, but also further enlarges the high-efficiency range. The high-efficiency range with a fuel consumption rate below 250g/kWh accounts for more than 70%, allowing the vehicle to even face more complex conditions. Under working conditions, it can still maintain a satisfactory level of low fuel consumption.

750N·m torque carrying capacity and more than 20 driving modes to enjoy a new smooth experience
As the central nervous system of the entire power system, Great Wall Motors' 9AT transmission also performs amazingly, with advantages such as good compatibility, high transmission efficiency, and large torque capacity. This mass production rollout will open up a new smooth driving experience for users.
Wang Yibo, Director of the Honeycomb Transmission 9AT Project of Great Wall Motors, explains the 9AT transmission
The 9AT transmission of Great Wall Motors adopts advanced technologies such as the independently developed hydraulic automatic transmission structural scheme optimization program, and is also more innovative Incorporating patented technologies such as ultra-highly integrated hydraulic control module, redundant parking system design, high-performance hydraulic torque converter, compact and efficient clutch design and intelligent control software, it can achieve a torque carrying capacity of up to 750N·m.
It can match engines of different displacements and types such as 2.0L, 3.0L gasoline or diesel, and meet users' stringent needs for strong and smooth power experience.
In addition, Great Wall Motors' 9AT transmission can also realize full life cycle adaptation in 3 categories and 4 working conditions. It can achieve full cycle synchronization through the FOTA system. It has more than 20 driving modes and can be customized. . At the same time, it can use advanced external perception algorithms to navigate different scenarios such as plateaus, mountains, and cities, and calmly face various complex terrains such as steep slopes, mud, and deserts, achieving load spectrum coverage in all working conditions. It can achieve comprehensive excellent performance in various scenarios and terrains, including long-distance crossings in harsh road conditions, off-road climbing, and wading.
