On January 24, 2026, at the Yuchai Group 2026 Global Partner Conference held in Yulin, China, Yuchai officially launched its groundbreaking "Yuchai Flywheel Range Extender System (FRS)" to the world.
This is not a routine product iteration, but a category creation based on fundamental physical structural innovation, marking the official transition of commercial power systems from the traditional "electrical splicing era" to the "physical coaxial integration era." With its unique flywheel motor core technology and in-depth verification across all scenarios, Yuchai has firmly established its strategic position as a global pioneer and leader in flywheel range extender technology.
The Yuchai Flywheel Range Extender System completely abandons the simple "engine + independent motor" superposition model commonly used in the industry. Through a rigid coaxial integrated design of the flywheel and engine crankshaft, it achieves a native integration of the power source and the generator unit in terms of physical structure. This core breakthrough, combining intelligent coupling control algorithms and multi-scenario adaptive energy management strategies, represents a fundamental evolution of the range extender from "split assembly" to "system symbiosis," resulting in a comprehensive leap in efficiency, reliability, and space utilization.
The system can be summarized into three core values: "Minimalist Structure, Ultimate Efficiency, and Extremely Stable Wealth Creation":
* **Minimalist Structure (Simplicity):** Highly integrated electromechanical components eliminate redundant connections, resulting in an order-of-magnitude improvement in system reliability and a lifetime maintenance-free core power unit.
* **Ultimate Efficiency (High Efficiency):** The engine's high-efficiency zone and the generator's high-efficiency zone completely overlap, achieving a peak generator efficiency exceeding 4.8 kWh/L for the diesel flywheel range extender system. The overall fuel saving rate can reach up to 50%, and operating costs in some scenarios are already superior to pure electric vehicles.
* **Extremely Stable Wealth Creation (Effectiveness):** No range anxiety, all-weather adaptability, and significantly improved uptime. With its ultra-low overall operating cost, Yuchai's flywheel range extender system helps users achieve a return on investment within one year in typical scenarios such as heavy-duty trucks and mining, redefining the TCO (Total Cost of Ownership) standard for commercial power systems.
Having undergone rigorous testing under demanding operating conditions, Yuchai's flywheel range extender system has achieved full coverage in both commercial vehicles and off-road applications. Its product line covers power outputs from 15kW to 600kW and is widely used in nine core areas, including long-distance logistics, urban public transport, heavy-duty mining, port machinery, and large agricultural equipment. It has become the most widely used, highest market share, and most technologically validated commercial range extender power system globally.
Currently, this system holds over 96% market share in the new energy loader market and maintains an absolute leading share in key areas such as wide-body mining trucks and large harvesting machinery, making it the preferred power source for high-end commercial equipment seeking an efficiency revolution.
At this conference, Yuchai simultaneously launched its full product matrix based on the FRS technology platform, including eight models such as the YCS04, YCK08N, and YCK16, comprehensively adapting to diverse needs ranging from light-duty buses to heavy-duty mining trucks. These products have been successfully integrated with major domestic and international commercial and construction machinery brands such as FAW, Dongfeng, XCMG, Sany, and Caterpillar, and have gained high market recognition.
Zhong Yuwei, Vice General Manager of Yuchai Group and Chairman of Yuchai Xinlan, stated, "The launch of the FRS system marks a strategic leap for Yuchai from 'technology leadership' to 'technology definition.' It is not merely a product, but rather Yuchai's 'ultimate efficiency solution' for the global commercial vehicle and off-road sectors. In the future, all of Yuchai's range-extending technology evolution will be rooted in the FRS platform. We will continue to deepen our dual-drive strategy of 'technological innovation + global strategy,' collaborating with global partners to jointly develop a new ecosystem of efficient, zero-carbon commercial power, leading the industry into a new era of 'flywheel range extension.'"
This significant launch of the Yuchai flywheel range extender system not only demonstrates Yuchai's profound technological reserves and forward-looking layout in the field of new energy power systems, but also provides a new technological path and business paradigm for the green and efficient development of the entire commercial power industry through a fundamental technological innovation.
