On May 11, a commercial minibus manufactured by Vochiton, fitted with Yuchai's YCY24 65kW Flywheel Range Extender System (YC-FRS), made its debut in Hong Kong. This launch marks the official entry of Yuchai's flywheel range extender technology into the Hong Kong market. It delivers a fully scenario-compatible, high-efficiency green power solution for the local passenger transport sector, and supports the low-carbon transformation of transportation across the Guangdong-Hong Kong-Macao Greater Bay Area.
As a global pioneer and industry leader in flywheel range extender technology, Yuchai's newly unveiled YCY24 65kW Flywheel Range Extender System is a benchmark power product purpose-built for urban public transport. Positioned on the core tenets of "Simple, Efficient, Reliable & Productive", it features an innovative rigid coaxial integrated design of the flywheel and engine crankshaft, enabling inherent integration of the power source and power generation unit.
This technology has been awarded the Second-Class Prize of the National Machinery Industry Science and Technology Progress Award, with its fuel-to-electricity conversion efficiency and power density both reaching world-leading standards.
The system addresses the key pain points of Hong Kong's passenger transport industry with dual breakthroughs:
On one hand, the engine consistently runs at its optimal operating point for stable power generation and is compatible with small-displacement configurations. It delivers up to 50% fuel savings in congested urban traffic, alongside merits including low operational noise, regenerative braking energy recovery, and access to preferential traffic policies for new energy vehicles.
On the other hand, it fundamentally resolves the inherent drawbacks of pure electric vehicles - high procurement costs, range anxiety, insufficient charging infrastructure and battery capacity degradation. Its fuel-electric hybrid operation requires no fixed charging stations and offers unlimited driving range, perfectly suited to Hong Kong's high-density, high-intensity commercial operation environment.
The successful market rollout of Yuchai's flywheel range extender system in Hong Kong validates the technology against stringent international market standards. It also represents a significant milestone for intelligent Chinese manufacturing in advancing integrated development of the Greater Bay Area.
Moving forward, Yuchai will continue to focus on new energy power systems and cooperate with partners across the industrial chain. The Company will provide premium green power solutions for Hong Kong and worldwide markets, accelerate the low-carbon transition of urban transportation, and steer the global development of green mobility through intelligent Chinese manufacturing.
