Great Wall Motor's 3.0T+9AT super powertrain consists of Great Wall Motor's 6Z30 engine and the first domestic V6 9-speed hydraulic automatic transmission. It has three characteristics of tenacity, high efficiency and reliability, and solves the contradiction between large displacement and low emission with the strong advantages of high energy and low consumption.
Great Wall Motor 6Z30 went offline this time? The displacement of the 3.0T engine is 3.0L, and the V-shaped six-cylinder layout is adopted. 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, the peak torque can be further increased to 550n·m by using 48V light-mixed BSG motor, and the engine can generate 340n·m powerful power at the low speed of 1000r/min.
Great Wall Motor 6Z30 3.0T engine is still eye-catching in reducing energy consumption. Through a series of advanced technologies, such as Miller cycle and full map oil pump, the upper limit of thermal efficiency is increased, and the mechanical loss is reduced, and finally the high thermal efficiency of 38.5% is achieved, which is extremely rare at the 3.0L displacement level. Great Wall Motor 6Z30 3.0T engine not only achieves extremely high single-point thermal efficiency, but also further enlarges the high-efficiency range, and the high-efficiency range with fuel consumption below 250g/kWh accounts for more than 70%, so that the vehicle can maintain a satisfactory low fuel consumption level even in the face of more complicated working conditions.
Great Wall Motor 9AT, as the central nerve of the whole power system, adopts advanced technologies such as the structural scheme optimization scheme of hydraulic automatic transmission independently developed. more innovative has patented technologies such as ultra-high integration hydraulic control module, redundant parking system design, high-performance hydraulic torque converter, compact and efficient clutch design, intelligent control software, etc., which can realize the maximum torque carrying capacity of 750N·m, and can match different types of engines such as 2.0L and 3.0L gasoline or diesel to meet users' strong and smooth power experience.
In addition, the 9AT transmission of Great Wall Motor can realize full life cycle adaptation in three categories and four working conditions, and realize full life cycle synchronization through FOTA system, with more than 20 driving modes and customization. At the same time, the external sensing algorithm can control different scenes such as plateau, mountain, city, etc., calmly face a variety of complex terrain such as steep slope, mud, desert, etc., and realize full-load spectrum coverage. It can achieve comprehensive excellent performance in various scenes and terrains, including long-distance crossing, cross-country climbing and wading under bad road conditions.
As a completely self-developed hard-core technology product, the mass production of "3.0T+9AT Super Powertrain" has verified the world's top R&D, supply and marketing hard power of Great Wall Motor. Great Wall Motor said that in the future, it will have a clearer and richer product layout, with leading technology and excellent quality as the core, adhere to innovation drive, open up a broader overseas market, realize the deep layout of global industries, and effectively promote the realization of Great Wall Motor's 2025 strategic objectives.
