Overview:

Cummins ISM continues to lead the way for heavy-duty diesels in its class. Thoroughly tested and proven to meet Cummins rigorous durability standards, the ISM satisfies the latest emissions requirements without expensive aftertreatment or special fuels. The bottom line: You win. With its proven reliability, impressive fuel savings and electronics that integrate all engine functions for low cost of operation, Cummins ISM is clearly ahead of the competition.

Exceptional Fuel Economy
Cummins ISM continues to deliver outstanding fuel economy, thanks to its electronically controlled fuel system with advanced air-handling technology. We expect the ISM to continue its fuel economy leadership of any engine in its class meeting the 2.5-gram NOx+NMHC emissions requirement.

Impressive Acceleration
The Variable Geometry Turbocharger (VG Turbo) produces quicker throttle response with less turbo "lag." In drivers' terms, that means more acceleration power to get your load moving, and faster acceleration for highway on-ramps.

Driver Satisfaction
While meeting EPA standards is important, keeping truck drivers happy is our number one priority. Drivers want an engine that can pull a steep grade without dropping a gear. An engine that gets high mpg with low maintenance. And an engine that provides helpful driver interaction and coaching through feedback of actual trip data.
