Yuchai Range Extenders Powering 222 New Energy Buses in Macau

SINGAPORE, May 17, 2022 /PRNewswire/ -- China Yuchai International Limited (NYSE: CYD) ("China Yuchai" or the "Company") a leading manufacturer and distributor of engines for on- and off-road applications in China through its main operating subsidiary, Guangxi Yuchai Machinery Company Limited ("GYMCL"), announced today that the city of Macau has begun operating 222 new energy buses equipped with Yuchai's range extenders. More than 600 units of Yuchai's core range extenders have been ordered for the Macau auto market.

Yuchai's range extenders feature the advantages of seamless integration, advanced fuel savings, superior reliability, and high adaptability, which can meet the power demands of different vehicles in various road conditions. Yuchai's YCS04-100kW and YCY24-65kW range extenders used in these buses in Macau are the core range extender products of GYMCL. 

The fuel consumption of these buses powered by Yuchai's range extenders is up to 4.20kW·h/L per liter, outperforming similar traditional buses in Macau, with a fuel saving of up to 50% and an annual carbon emission reduction of 50%. Compared with traditional vehicles, a new energy bus with range extenders can save nearly 14.2 tons of fuel per year, and reduce carbon emissions by about 43.8 tons.

The Yuchai core range extenders have won contracts from many first-tier domestic bus producers including Yutong Bus, Suzhou Golden Dragon Bus, and Zhongtong Bus.

Weng Ming Hoh, President of China Yuchai commented, "The congested road conditions in Macau and rapidly rising fuel cost presents an opportunity for our range extenders. We are pleased to win this contract and will continue to introduce new range extender products to offer our customers a choice of "Green" solutions."
