SINGAPORE, May 22, 2026 /PRNewswire/ -- China Yuchai International Limited (NYSE:CYD) ("China Yuchai International" or the "Company"), one of the largest powertrain solution manufacturers through its main operating subsidiary in China, Guangxi Yuchai Machinery Company Limited ("Yuchai"), today announced that a small batch of commercial minibuses equipped with Yuchai's YCY24-65kW Flywheel Range Extender System (YC-FRS) has been launched by Wisdom Motor in Hong Kong SAR. The system delivers an efficient and eco-friendly propulsion solution for local transport across a wide range of operational conditions, while supporting the transition to more sustainable transportation in the Guangdong-Hong Kong-Macao Greater Bay Area.

Yuchai unveiled YC-FRS as an innovative power system designed for city transportation vehicles. This system features an innovative design that seamlessly integrates the flywheel and the engine crankshaft through a rigid coaxial configuration, combining the engine and alternator into one single unit.

Powered by a dual fuel–electric replenishment mode that removes the need for fixed charging infrastructure, the YC-FRS offers virtually unlimited range. This capability makes it particularly well–suited to the heavy traffic and frequent start-stop operational road conditions of Hong Kong SAR.

With this system, the engine consistently generates power under optimal operating conditions, making it compatible with small-displacement vehicle models and enabling fuel savings of up to 50% in congested urban traffic. Additional benefits include low operating noise, regenerative braking, and priority road access reserved for new energy vehicles. The YC-FRS also addresses challenges that pure electric powertrain systems face in the Hong Kong public passenger transport market including high acquisition costs, range anxiety, limited charging infrastructure, and battery degradation.

Weng Ming Hoh, President of China Yuchai International, commented, "The successful deployment of Yuchai's flywheel range–extension system in Hong Kong SAR marks a significant step forward in advancing next–generation, new–energy powertrain technologies and strengthening collaboration across the industrial chain to deliver sustainable powertrain solutions to domestic and global markets. Our continued R&D efforts will help drive the low–carbon transformation of urban transportation and contribute to the future development of green mobility."
