The FAW Jiefang J7 Leading Edition tractor truck will be launched at the “6th Guangzhou International Commercial Vehicle Exhibition” from November 15-18, 2024. The globally launching J7 Leading Edition includes two high-powered “diesel” models and one “natural gas” model. The 13L and 16L “diesel” models are equipped with: 640hp CA6DV1 engine and 700hp CA6DX1 engine respectively. In September this year, the “TIR Cross-border Long-distance Test Journey” from Zhengzhou, China to Moscow used the 700hp model, which is particularly suitable for “ultra-high time-sensitive” special freight scenarios.
With the launch of the J7 Leading Edition, the “Smart Power Domain GD300-3.0” officially enters consumers’ view. Taking the 13L J7 Leading Edition diesel model as an example, it features FAW Jiefang’s new generation engine, transmission, and axle assembly. The CA6DV1 engine is Jiefang’s new generation world-class dual overhead 13L engine in the green smart power domain, and it’s the “first” mass-produced engine in the industry with 49.6% thermal efficiency. The matching CA12TA300A integrated AMT is Jiefang’s new generation integrated AMT transmission in the green smart power domain, and also the world’s first 3000N·m direct gear high-integration AMT product. Combined with the lightweight 440 axle, which is Jiefang’s new generation efficient lightweight heavy-duty drive axle, these three major independent powertrains form the “Smart Power Domain GD300-3.0”!
As the most efficient smart power domain in the industry, the GD3.0 powertrain combination, developed specifically for high-end express transportation conditions, offers advantages in high power, high time efficiency, and high adaptability.
Specifically, the vehicle delivers powerful performance and quick response. The CA6DV1 engine uses integrated pulse exhaust technology with a 300bar high-pressure platform, achieving a maximum torque of 3000N·m and rated power of 640Ps. Its 0-80km/h acceleration time, transient response, and plateau power performance are 10% better than other vehicles. In terms of absolute power, it far exceeds the industry’s 13L engine level and can match 15L engines. The low-speed torque in high-end logistics scenarios can both ensure powerful performance and reduce engine speed, achieving systematic fuel efficiency.
In highland and mountainous road conditions, the J7 Leading Edition can handle easily, with effortless starting and climbing. The CA6DV1 engine employs advanced technologies such as electronically controlled exhaust wide-valve turbocharging and plateau self-identification correction, minimizing power loss at high altitudes. It maintains full torque at 3,000 meters and sustains power at 4,000 meters altitude. Combined with the “golden speed ratio” and intelligent transmission technologies including cross-speed starting control and intelligent power shift patterns, it ensures optimal performance across all speeds and gradients. The vehicle starts swiftly and smoothly, with climbing ability 10% better than comparable models, easily handling highland mountain roads.
The GD300-3.0 integrated vehicle domain controller for Green Intelligent Power is a centralized, multi-core CPU/GPU solution that replaces traditional distributed automotive electrical and electronic architectures with advanced control capabilities. With 17 key functions within the power domain, it features a 4-core processor with a 300MHz clock speed and 10MB of high-speed flash memory, supporting high-speed communication, compact layout, and strong compatibility. Employing a wheel-end energy demand control architecture, it enables precise control over combustion, accessory coordination, gearshift pre-control, integrated thermal management, braking coordination, task allocation, and collaborative control between the vehicle and driver. Additionally, it supports scenario-based coordination, global planning, temperature pre-control, intra-domain collaboration, and digital twin functions, thereby meeting the economic and efficient usage needs of truck drivers.
Reportedly, this high-efficiency gold-standard power domain leads competing products by 3-5% in overall efficiency, with fuel savings of over 3%. This translates to an annual fuel cost savings of approximately 15,000 yuan for users, maximizing every drop of fuel!
