• The ISM's Variable Geometry Turbocharger produces quicker throttle response with less turbo "lag."
SmartTorque automatically adds up to 100 extra lb-ft of torque in the top two gears, for better fuel economy and fewer shifts. 
• Exceptional Power-to-Weight-Ratio - With ratings up to 500 hp and 1550 lb-ft of peak torque.
• Improved compression braking with the fully integrated C Brake by Jacobs.
Rear Engine Power Take-off (REPTO) is available for vehicles that need an engine to do double-duty.
• Fully integrated electronic controls using Cummins ECM provide increased performance from all subsystems.

Fuel Economy
Cummins ISM delivers excellent fuel economy, thanks to its electronically controlled fuel system with advanced air-handling technology.

• To achieve the best fuel economy with Cummins ISM, spec'ing one of our two SmartTorque ratings is a great option.
Cummins PowerSpec, the online tool that describes each engine feature, gives recommended settings and lets you modify and optimize operation of your Cummins engines. 
• Improve mpg even further, get RoadRelay™ 4, the in-cab monitor that helps drivers improve their own skill level.
