On January 24, 2026, at the 2026 Yuchai Group Global Partner Conference held in Yulin, China, Yuchai officially unveiled its groundbreaking “Yuchai Flywheel Range Extender System (FRS)” to the world.
This is not a conventional product iteration, but a category innovation based on underlying physical structure breakthroughs. It marks the official transition of commercial power systems from the traditional “electrical-mechanical splicing era” to the “physical coaxial integration era”. Leveraging its proprietary flywheel motor core technology and full-scenario in-depth validation, Yuchai has established its strategic position as the global pioneer and leader in flywheel range extender technology.
The Yuchai Flywheel Range Extender System completely abandons the industry-common simple superposition model of “engine + independent motor”. Through a rigid coaxial integrated design of the flywheel and engine crankshaft, it achieves the inherent integration of the power source and power generation unit in physical structure. This core breakthrough, combined with intelligent coupling control algorithms and multi-scenario adaptive energy management strategies, completes the essential evolution of the range extender from “split assembly” to “organic coexistence”, bringing comprehensive leaps in efficiency, reliability and spatial layout.
The system condenses three core values: “Ultimate Simplicity, Ultimate Efficiency, Ultimate Stability for Prosperity”:
· Ultimate Simplicity (Simplicity)
Highly integrated mechatronics design eliminates redundant connecting components, achieving an order-of-magnitude improvement in system reliability. The core power unit realizes lifelong maintenance-free operation.
· Ultimate Efficiency (Efficiency)
The engine’s high-efficiency zone fully overlaps with the power generation’s high-efficiency zone. The diesel flywheel range extender system achieves a maximum power generation efficiency exceeding 4.8kWh/L, with a comprehensive fuel saving rate of up to 50%. In some scenarios, the operating cost is already superior to that of pure electric vehicles.
· Ultimate Stability for Prosperity (Productivity)
No range anxiety, full climate adaptability, and significantly improved operational availability. With ultra-low comprehensive usage costs, it helps users in typical scenarios such as heavy-duty trucks and mining transportation achieve an investment payback period of less than 1 year, redefining the TCO (Total Cost of Ownership) standard for commercial power systems.
After rigorous working condition validation, the Yuchai Flywheel Range Extender System has achieved full coverage of commercial vehicles and non-road equipment. Its product lineup covers a power range of 15kW to 600kW, widely used in nine core fields including long-distance logistics, urban public transport, mining heavy load, port machinery and large agricultural equipment. It has become the commercial range extender power system with the widest global application scope, highest market share and most sufficient technical validation.
Currently, the system holds a market share of over 96% in the new energy loader market, and maintains an absolute leading position in key fields such as mining wide-body vehicles and large harvesting machinery, making it the preferred power choice for high-end commercial equipment seeking efficiency revolution.
At the conference, Yuchai simultaneously launched a full-series product matrix based on the FRS technology platform, including eight models such as YCS04, YCK08N and YCK16, fully adapting to diverse needs from light buses to heavy-duty mining trucks. These products have been successfully matched with mainstream domestic and foreign commercial and engineering machinery brands such as FAW Jiefang, Dongfeng, XCMG, Sany and Caterpillar, gaining high market recognition.
Zhong Yuwei, Deputy General Manager of Yuchai Co., Ltd. and Chairman of Yuchai Xinlan, stated: “The launch of FRS is a strategic milestone marking Yuchai’s leap from ‘technology leadership’ to ‘technology definition’. It is not just a product, but the ‘ultimate efficiency solution’ provided by Yuchai for the global commercial vehicle and non-road sectors. In the future, all Yuchai’s range extender technology evolutions will be rooted in the FRS platform. We will continue to deepen the dual-wheel drive of ‘technological innovation + global strategy’, collaborate with global partners to jointly develop a new efficient and zero-carbon commercial power ecosystem, and lead the industry into a new era belonging to ‘flywheel range extension’.”
The landmark launch of Yuchai’s Flywheel Range Extender System not only demonstrates Yuchai’s profound technical reserves and forward-looking layout in the new energy power system field, but also provides a brand-new technical path and business paradigm for the green and efficient development of the entire commercial power industry through a fundamental technological innovation.
