Get behind the wheel of a Metro-Liner, Super-Liner or Cummins engine and you'll find Cummins power providing plenty of motivation up front. Mack and Cummins have worked closely to develop premium Exhaust Gas Recirculation (EGR) power packages. The ISC, ISL, ISX and Signature 600 engines really complement the Mack Trucks.

The Mack MP8 and Cummins engines use the same emissions technology with a Variable Geometry Turbo (VGT) and a self contained, cooled EGR system providing reliability without sacrificing fuel efficiency.

And if you were worried about performance - don't be.

Exhaustive analysis, testing and real world operation over billions of kilometres have resulted in stronger power and torque curves, with improved throttle response and greater engine braking.

These engines keep Mack ahead of the pack in the high horsepower market.

They're reliable, they're strong and they're ready to handle future emissions levels without fuss.
