On April 19th, at the Shanghai International Automobile Industry Exhibition, Great Wall Motor’s subsidiary, Beijing Great Wall Huading Automobile Powertrain Co., Ltd. (hereinafter referred to as “Great Wall Powertrain”), officially released the “Super Powertrain” 3.0T + 9 AT/ 9 HAT.
Zheng Lipeng, Co-Chairman of Beijing Great Wall Huading Automobile Powertrain Co., Ltd., introduced that this powertrain was independently developed by Great Wall Motor. The powertrain, codenamed 6Z30 engine and consisting of the country’s first 9-speed hydraulic automatic transmission / the first P2 hybrid 9-speed hydraulic automatic transmission, is used for the tank platform with longitudinal layout and will achieve mass production within the year.
As the flagship power of Great Wall Motor’s efficient fuel technology, the 6Z30 3.0T engine adopts a V-shaped 6-cylinder configuration with many advanced technologies in the engine field such as dual injection system, Miller cycle, dual VGT turbocharger, intake manifold integrated water-cooled intercooler and full map oil pump. It can output a maximum power of 260 kW and a maximum torque of 500 N·m, making it the most powerful power among Chinese automotive brand’s 3.0 L displacement engines. It is also powerful at low speeds and can releases 340 N·m of torque at only 1,000 rpm, covering various off-road life-related product categories such as large SUVs, pickups, and RVs. Moreover, this engine also meets emission standards such as China 6b + RDE, Euro VI d, SULEV30, etc.
Great Wall Motor’s 9AT automatic transmission, as the country’s first 9-speed hydraulic automatic transmission, employs independently developed hydraulic automatic transmission structure scheme optimization programs and intelligent integrated hydraulic-electronic modules. It achieves a transmission carrying capacity of up to 600 N·m while ensuring controlled transmission size. Based on the strong torque support of the 3.0T engine, the 9AT transmission sets the 7th, 8th and 9th gears as over-speed gears to improve the vehicle’s fuel economy performance. During daily driving, the 9th gear can be engaged when the vehicle speed reaches about 90 km/h.
The 9HAT transmission is the first P2 hybrid 9-speed hydraulic automatic transmission in China. With the addition of a high-power P2 hybrid motor on the basis of the 9AT, the 9HAT can achieve pure electric or hybrid driving modes for the entire vehicle. Meanwhile, the 9HAT also maintains a maximum transmission capacity of up to 750 N·m with controllable transmission size.
The 3.0T + 9HAT powertrain achieves a maximum combined output power of 410 kW and peak torque of 750 N·m.
Today, as everyone is embracing electrification, Great Wall Motors has launched a high-displacement engine and 9AT gearbox that meets the stringent emission requirements. This move towards true high-end products requires even greater courage.
