Application:
QSX15: A mainstay model from the 2000s to early 2010s, primarily used in North America and some export markets for heavy-duty tractors, mining trucks, construction machinery (such as milling machines), and generator sets. Common power outputs ranged from 400 to 675 horsepower (e.g., the QSX15-C525, with 533 horsepower used in mining dump trucks). Production has ceased, and it was replaced by the ISX15.

ISX15: Mainstream models from 2010 to 2020 (including ISX15E5 and other China V/China VI versions), designed specifically for compliant heavy-duty truck markets such as North America and China, used in long-haul logistics tractors, engineering vehicles, dump trucks, etc., with power ranging from 400 to 600 horsepower (such as the 610 horsepower China V version);

X15: The latest generation from 2017 to present (including the X15 Efficiency/Performance series), fully adapted to the latest global emissions standards (such as EPA 2010/China VI), used in high-end heavy-duty trucks, cold chain tractors, port tractors, mining and special vehicles, with power ranging from 400 to 605 horsepower (some Performance versions reach 675 horsepower), integrating intelligent control and higher fuel efficiency, currently the mainstream heavy-duty truck model globally.
