To validate the practical operational performance of the Yuchai YC6MK380-30 engine in long-haul road passenger transport, comprehensive on-road trials were conducted across high-grade cross-border corridors linking Lahore and Islamabad, Pakistan. The test vehicle operates on high-speed intercity expressways with a 760-kilometer round trip, fully replicating the typical operating conditions of cross-border road passenger services in South Asia.
The test unit is a Xiamen Golden Dragon XML6129 passenger coach, exclusively powered by the Yuchai YC6MK380-30 engine and paired with a Fast 6-speed transmission. This powertrain configuration is optimized to deliver stable, high-performance output for long-haul operations at typical cruising speeds of 80–120 km/h, perfectly aligning with the demands of high-speed intercity passenger transport in South Asia.
