Overview
The ISMe engine series by Cummins is designed for heavy-duty performance, offering benchmark standards in fuel efficiency, driveability, and reliability. Known for its excellent transient response and overall refinement, the ISMe engine is lightweight at 940 kg, providing a payload advantage while maintaining a life-to-overhaul goal of one million kilometers.

Productivity
The ISMe engines are optimized for specific applications, balancing performance and cost-efficiency for vehicles weighing 26 to 44 tonnes. The ISMe-445 model is particularly suited for 44-tonne operations, offering high torque capability and fuel economy with 2100 Nm peak torque at 1200 rpm.
