On August 10, the new Changzheng No,1 dual-motor heavy-duty truck was officially launched, marking a significant upgrade in the commercial vehicle market. This new model’s core highlight is its fully self-developed dual-motor central drive system, which offers advantages such as uninterrupted shifting and sustained power compared to other similar products on the market. This launch is another demonstration of Changzheng Auto’s commitment to developing vehicles centered around user needs and specific commercial use cases.
A New Milestone in Scenario-Based Vehicle Development
According to a report by CCTV News, the domestic fleet of new energy heavy-duty trucks reached approximately 80,000 units in the first half of 2024, doubling from the previous year. However, the highest penetration of pure electric heavy-duty trucks is still in short-haul transport scenarios, where most vehicles are driven by single-motor systems. These systems, often based on modified traditional fuel vehicles, feature separate motor and transmission designs, leading to issues like power interruptions during gear shifts, increased weight, and reduced efficiency.
Drawing insights from the specific use cases of pure electric heavy-duty trucks, Changzheng Auto, leveraging the capabilities of Great Wall Motors, developed the dual-motor model from the ground up. The vehicle features a self-developed oil-cooled, co-lubricated dual-motor drive system and intelligent control strategies. These innovations are designed to help customers achieve lower energy consumption throughout their vehicle operations. The truck also exhibits superior performance in navigating complex road conditions, ensuring better drivability and consistent power output, thereby enabling users to reduce costs and increase efficiency.
Designed for Efficient Logistics: Dual-Motor Central Drive
The dual-motor version of the Changzheng No,1 heavy-duty truck uses a mature, mass-produced oil-cooled flat wire motor, achieving an efficiency of up to 97%. The motor’s power range, from 360 kW to 450 kW, caters to various vehicle needs. Moreover, the deep integration of the motor with a 4-speed AMT (Automated Manual Transmission) in a shared housing, cooling, and lubrication system allows for extreme lightweight design, significantly increasing the vehicle’s payload capacity and helping customers achieve faster and more efficient operations.
Notably, the dual-motor central drive system in the new model is based on a mature dual countershaft structure, incorporating an innovative multi-countershaft power compensation solution. The vehicle’s drive system efficiency is significantly improved through intelligent dual-motor control and comprehensive forced lubrication technology. This enhancement increases the vehicle’s single-charge range and ensures that the truck can maintain power and smooth shifting even on steep inclines.
More Value for Money: Offering Superior Choices to Customers
In today’s logistics market, where profit margins are calculated down to the last cent, cost reduction and efficiency improvement have become critical factors, influencing every aspect of operations. By understanding the real-world operational needs of its customers, Changzheng Auto has timely introduced the dual-motor pure electric heavy-duty truck, offering enhanced features without increasing the price. This ensures that users get more value for their money, experiencing faster speeds and longer ranges with the same battery capacity, as well as quicker and more cost-effective operations over the same distances.
The launch of the new Changzheng No,1 dual-motor heavy-duty truck not only enriches the product lineup of Changzheng’s new energy heavy-duty trucks but also represents an extension of Great Wall Commercial Vehicles’ commitment to user-centered, scenario-based vehicle innovation. Looking ahead, Great Wall Commercial Vehicles will continue to focus on user needs and lead with technology, providing high-quality, reliable products that support the logistics industry’s transition to greener and smarter solutions.
