Over the past two years, more truck drivers have switched to electric heavy-duty trucks. Compared with diesel counterparts, electric trucks deliver lower energy costs, quieter operation and easier maintenance. On June 7, Dongfeng Liuzhou Motor hosted the 10th 67 Brand Customer Day at Liuzhou International Convention and Exhibition Center in Guangxi, where it unveiled the all-new Chenglong EV5 Ultra Edition battery-electric tractor. Built on a brand-new platform, the model stands out with ultra-light curb weight and ultra-low power consumption. This article delivers a full breakdown of its highlights.
Family Styling: Grand yet Exquisite
We start with exterior design as usual. The Chenglong EV5 Ultra Edition inherits Chenglong’s consistent family design language, featuring smooth rounded contours paired with tough styling cues. True to its all-electric identity, it adopts a fully closed front fascia decorated with diffusive graphic decals and wrap-around air deflectors on both sides. This package cuts aerodynamic drag and wind noise while delivering a striking visual appearance.
The rugged front bumper incorporates vertical slat air intake grilles that amplify visual toughness and give the vehicle a powerful, imposing stance. Anti-slip treads on the bumper top allow drivers to stand comfortably and clean the windshield. A protruding millimeter-wave radar sits at the center of the footrest area, supporting the AEBS automatic emergency braking system and a full suite of active safety functions.
Standard LED headlights deliver superior illumination and drastically boost driving safety at night and in harsh weather. Separate fog lamps are mounted below, framed by black trim to form a distinctive teardrop styling for refined aesthetics.
Full-Scope 1000V High-Voltage Platform, Ultra-Light Weight & Minimal Power Draw
Intensifying competition has squeezed profit margins across the logistics sector, making cost reduction and efficiency gains the core industry priority. Built on Dongfeng Commercial Vehicle’s T1 new energy platform, the Chenglong EV5 Ultra Edition leverages cutting-edge technology to address market pain points, boasting six core strengths: ultra-light weight, ultra-low energy consumption, ultra-fast charging, top-tier safety, outstanding reliability and comprehensive intelligence.
It adopts an integrated MTB battery pack with a highly compact layout and elevated system energy density. Batteries are mounted low on both sides of the chassis, lowering the vehicle’s center of gravity by over 20% for enhanced high-speed stability and safety. Two battery capacity options are offered for different operating scenarios: 422 kWh and 633 kWh. The 422 kWh variant features an industry-leading short wheelbase of only 3,350 mm for superior maneuverability, ideal for tight yards and narrow access roads.
The truck is equipped with a high-efficiency 1000V electric drive axle achieving a system efficiency above 94.5%, ranking among the industry’s best. Each single axle outputs 350 kW, with dual axles combining for a total 700 kW — equivalent to roughly 952 horsepower. The nearly 1,000 horsepower output enables effortless heavy-load launches and overtaking.
Industry-leading lightweight technologies are extensively applied, including newly structured lightweight frames, upgraded large aluminum brackets and integrated aluminum housings for the drive axles. Six lightweight optimization approaches — new materials, innovative structures, advanced manufacturing processes, topology optimization, functional integration and assembly refinement — bring the curb weight of the 422 kWh version down to merely 8.8 tons, over 500 kg lighter than competing models. This cuts power consumption and enables higher payloads for greater revenue.
Supported by the full-range 1000V high-voltage architecture, an integrated 8-in-1 domain controller and full-scope integrated thermal management, paired with adaptive intelligent calibration and algorithm tuning, the vehicle’s overall energy consumption is reduced by more than 5.5%. Attenuation of driving range in extreme high and low temperatures is effectively controlled, with combined power consumption reaching an industry-leading low of 1 kWh per kilometer. The advanced platform strikes a perfect balance between extreme performance and ultra-low energy use, translating to larger payloads, longer range and lower operational costs in real-world haulage.
High-Safety Cabin with Elevated Interior Experience
Cabin design has long been a signature strength of Chenglong, and the EV5 Ultra Edition carries this legacy forward. It adopts Chenglong’s 3rd-generation keel-structured cabin, where high-strength steel accounts for over 30% of the body structure. Front crash safety performance is improved by 40%, greatly enhancing passive protection for drivers and passengers.
Inside the wrap-around cockpit, a full LCD instrument cluster and four-spoke multifunctional steering wheel deliver intuitive control. Premium finishes such as wrapped door armrests and refined dashboard panels upgrade the cabin’s upscale ambiance.
A column-mounted gear shifter is fitted to the right side of the steering column for easy reach, freeing up valuable interior floor space. The dashboard features sleek black piano-lacquer trim that seamlessly integrates the handbrake, air vents and control panels for a cohesive, high-finish interior layout.
The control panel consolidates multi-mode switches and adjustable regenerative braking controls for one-touch operation. Thanks to the high-efficiency integrated drive axle, maximum regenerative braking power hits 100%, delivering powerful auxiliary braking that boosts safety on long downhill stretches while further cutting energy consumption.
The test vehicle with the 422 kWh battery pack is designed for short shuttle runs and comes with a single sleeper. The generously wide lower bunk ensures a comfortable rest space.
Conclusion
With shrinking profit margins and fiercer competition across the transport industry, cutting costs and lifting efficiency have become truck operators’ most urgent demands. The Chenglong EV5 Ultra Edition battery-electric tractor directly targets these pain points. Its ultra-light 8.8-ton curb weight, industry-leading 1 kWh/km power consumption, plus robust power and fast charging enabled by the full-range 1000V high-voltage platform, truly realize greater payloads with lower running costs. Meanwhile, the 3rd-generation crash-resistant keel cabin and comprehensive active safety features grant extra peace of mind to drivers logging long hours on the road.
More than a technological leap forward for Dongfeng Liuzhou in the new energy heavy-duty truck segment, the EV5 Ultra Edition serves as a reliable partner helping truck drivers boost profits and stay ahead of market competition.
