Great Wall Motors Shanghai Auto Show released 3.0T+9AT/9HAT super power
China Automotive News, April 20th. Yesterday, Great Wall Motors officially unveiled the world’s first high-end powertrain for a Chinese automobile brand at the 2021 (19th) Shanghai International Automobile Industry Exhibition-3.0T+9AT/ 9HAT super powertrain. At the press conference, Zheng Lipeng, co-chairman of Great Wall Auto Hive Yichuang, gave a wonderful introduction to the product technology and future layout of this super powertrain.
It is reported that this set of powertrain consists of a 6Z30 engine completely independently developed by Great Wall Motors and the first domestic 9-speed hydraulic automatic transmission/the domestic first P2 hybrid 9-speed hydraulic automatic transmission. The installed tank platform has three major characteristics: powerful, efficient and reliable, and will be mass-produced within this year.

Fill the gaps in China's high-end powertrain field and show the hard power of Great Wall Motors
In recent years, Chinese auto brands have continued to make efforts in technology research and development, and product performance and quality have been continuously improved. The small and medium displacement power combination represented by Great Wall Motors 4N20 series engines and 9DCT/9HDCT has gained consumer recognition and Favor, sales in the mainstream market are steadily increasing.
Vertical hybrid four-wheel drive platform equipped with 3.0T+9AT powertrain
However, in the high-end market, although Chinese car brands have a very small number of large-displacement engines, there is currently no independently developed high-level transmission to match it. The 3.0T+9AT/9HAT super powertrain released by Great Wall Motors this time has made up for the gap in China's high-end powertrain field and once again demonstrated Great Wall Motor's hard power to lead China's 'core'.
6Z30 3.0T twin turbocharged engine
As the flagship power of Great Wall Motor's high-efficiency fuel technology route, the 6Z30 3.0T engine adopts a V-type 6-cylinder type, adopts dual injection system, Miller cycle, dual VGT supercharger, and intake manifold integrated water cooling. Many advanced technologies in engine fields, such as coolers and full-map oil pumps, can output 260kW of maximum power and 500N·m of maximum torque. They are the strongest power among Chinese automobile brands' 3.0L displacement engines. And low-torque and strong, it can burst out 340N·m of torque at 1000rpm, which can cover a variety of off-road life-related products such as large SUVs, pickups, and RVs. At the same time, this engine also has high efficiency, low emissions and other highlights, meeting the national 6b+RDE, Euro VI d, SULEV30 and other emission standards.
9AT transmission
Great Wall Motor released two transmissions, 9AT and 9HAT. Among them, the 9AT transmission is an advanced transmission used in the vertical high-efficiency fuel power system; the 9HAT transmission is an advanced P2 hybrid transmission used in the hybrid power system. With the release of Great Wall Motors 9AT and 9HAT transmissions, the technical barrier was broken in one fell swoop. The start is high-end and the start is the lead.
As the first 9-speed hydraulic automatic transmission in China, Great Wall Motor 9AT transmission adopts self-developed hydraulic automatic transmission structure scheme optimization program and intelligent integrated electronic hydraulic module and other technologies to achieve transmission performance breakthroughs. Under the condition that the transmission size is controllable, a transmission load capacity of up to 600N·m is realized. Based on the powerful torque support of the 3.0T engine, the 9AT transmission sets the three gears 7, 8, and 9 as overspeed gears to improve the fuel economy performance of the vehicle. In daily driving, the 9th gear can be engaged when the vehicle speed reaches about 90km/h.
9HAT transmission
The 9HAT transmission released this time is the first P2 hybrid 9-speed hydraulic automatic transmission in China. On the basis of 9AT, 9HAT adds a high-power P2 hybrid motor, which can realize the pure electric or The hybrid drive mode achieves a transmission load capacity of up to 750N·m while ensuring that the transmission size is controllable, further improving the power and smoothness of the vehicle. In the end, the 3.0T+9HAT powertrain achieves a total system power of 410kW and a peak torque of 750N·m.
Mass production is coming soon. Great Wall Motor's power family layout will be further advanced
The 3.0T+9AT/9HAT super powertrain will be mass-produced within this year and will be mounted on the tank platform. The tank platform is positioned as a global intelligent professional off-road platform. Since its release, it has always provided users with the ultimate off-road capability with powerful power and intelligent off-road mode. With the mass production application of the 3.0T+9AT/9HAT super powertrain, the tank platform will be even more powerful, driving further improvements in power performance, and providing users around the world with the ultimate off-road experience.
Great Wall Motors Advanced Powertrain Family
In recent years, with the persistence of the Ru0026D concept of 'precise investment and pursuit of industry leadershipA series of power system products such as a pure electric bridge. It has formed a complete layout of system power from 35kW to 320kW, system orientation from energy saving to performance, and vehicle models from A00 to D. The release of Great Wall Motor’s 3.0T+9AT/9HAT super powertrain will boost Great Wall Motors to achieve breakthroughs in the higher-level market with extreme power, compete with foreign brands, and become a high-end Chinese car brand. Important milestones.
