On June 7, the annual Dongfeng Liuzhou motors(dflzm) 67 Brand Customer Day was grandly held. At the event, DFLZM solemnly released the Chenglong YIWEI 5, a new-generation new energy heavy-duty truck platform. As the first model built on DFLZM’s new-generation new energy architecture platform, the Chenglong YIWEI 5 has achieved comprehensive breakthroughs in lightweight design, energy conservation, range, safety, and intelligence, leading new energy heavy-duty trucks into a new era of green and high-intelligence.
Oriental Aesthetics Integrated with Comfort Design to Create a Full-Scenario Comfortable Cockpit
The appearance of the Chenglong YIWEI 5 not only embodies the essence of Oriental Dragon Soul aesthetics but also integrates cutting-edge technology. The 21 exquisitely crafted hollow decorative strips at the front grille are arranged in an array, inspired by the scales of ancient armor, symbolizing the perseverance to guard the logistics journey. They also form a stepped diversion structure. The intake duct design inspired by fighter jets on both sides balances visual appeal and functionality, reducing the vehicle’s drag coefficient by 10% for more efficient logistics transportation.
In terms of driving comfort, Chenglong and its partners have carefully created a full-scenario comfortable cockpit based on deep insights into the operation scenarios of new energy heavy-duty trucks. The vehicle has a leading 1.93-meter standing space in its class, combined with luxury sedan-level interior configurations, bringing unprecedented comfort to truck drivers. Meanwhile, the “one-key recline” spine-protecting seat is developed. When truck drivers are queuing for loading or resting during charging, they can switch to a 150° golden recline angle with one key, reducing muscle and bone pressure by 40%, minimizing the risk of lumbar strain, preventing occupational diseases, and fully ensuring driving comfort.
Three-Electric Innovation Drives the Future, Pushing Operational Efficiency to New Heights
Three-electric (battery, electric drive, and electronic control) technologies are the core competitiveness of new energy heavy-duty trucks. The Chenglong YIWEI 5 has made comprehensive breakthroughs in three-electric technologies, empowering customer operations with full-life cycle value.
- Battery: All models use high-safety lithium iron phosphate cells, paired with ASIL-D safety-level high-strength structures and aviation-grade thermal insulation materials, providing dual insurance for battery safety. The battery cycle life of medium and heavy trucks reaches 4,500 times or 8 years, completely eliminating users’ worries. With super fast charging, SOC 20%–80% charging takes only 30 minutes, and the battery swap version achieves 5-minute ultra-fast battery swap, truly solving range anxiety.
- Electric Drive: Breaking through traditional technologies, it is equipped with a high-speed flat-wire motor with a power density of 2.8kW/kg, and the high-efficiency range (≥90%) accounts for over 90%. Combined with dynamic coupling algorithms, it balances power and energy consumption, ensuring full-life cycle cost optimization for users in both frequent stop-and-go urban distribution and heavy-load climbing in mining transportation.
- Electronic Control: With high hardware integration, it adopts integrated domain control fusion technology, reducing the assembly volume by 6%. The intelligent energy management algorithm optimizes torque distribution based on real-time load, slope, and other information, further improving energy recovery and reducing vehicle energy consumption.
In terms of intelligence, relying on Dongfeng Group’s “Tianyuan Intelligence” technology system, it achieves intelligent load identification, improves energy recovery efficiency, and offers multiple intelligent functions and the pioneering “AI Cloud Follow” service, making the vehicle more energy-efficient and safer over time.
Safe, Reliable, Lightweight, and Profitable, Ensuring Smooth Logistics Transportation
Safety is the bottom line of transportation. The Chenglong YIWEI 5 adopts a third-generation keel-type cab frame, with over 30% high-strength steel and military-grade materials at key stress points, improving frontal collision safety by 40% and deformation resistance by 50%, fully safeguarding drivers.
The three-electric system has a ground clearance of 670mm, with core components reaching IP68 waterproof standards. The centralized protection design of the three-electric system increases high-pressure water safety by 70%, comprehensively enhancing wading and impact resistance. It undergoes strict testing to verify quality, ensuring reliability and durability throughout the life cycle.
In terms of active safety, the AEBS active braking system links with load identification and road adhesion coefficient estimation, with braking efficiency 20% faster than similar products. It also features 360° panoramic view，lane change assistance, and other functions to escort complex road conditions.
While ensuring safety, the Chenglong YIWEI 5 has also made great efforts in vehicle lightweighting. Through topology optimization and modular design, the body structure is “shaped on demand”. Using high-energy-density batteries, lightweight frames, and a large proportion of high-strength steel, it achieves leapfrog weight reduction. For example, the resource transportation tractor with a 400kWh battery weighs only 8.8 tons, over 700kg lighter than similar products, helping customers earn an additional 20,000–30,000 yuan annually.
The birth of the Chenglong YIWEI 5 is a powerful practice of DFLZM’s “doubled product power” concept, meticulously crafting every vehicle. It also demonstrates DFLZM’s firm determination to adhere to innovation-driven development and cultivate new productive forces. DFLZM will continue to create higher value for logistics users with more efficient and intelligent logistics transportation solutions.
