Cummins ISX15 engine averaged 9.9 mpg during testing last fall on U.S. Route 287 between Fort Worth and Vernon, Texas.
The Cummins ISX15 is the only engine offered as an option by every major truck manufacturer in the business and is the most popular heavy-duty engine in North America.
It was the first engine certified to meet 2014 Environmental Protection Agency (EPA) and Department of Transportation (DOT) regulations, a full year ahead of schedule.
The ISX15 is equipped with On-Board Diagnostics (OBD) which monitors and ensures optimal performance of the emissions system.
Better Fuel Economy.
The Cummins ISX15 is the industry leader in fuel economy, and it keeps getting better.
This, together with optimized combustion and fewer active regenerations of the after-treatment system, means better fuel economy. Better Reliability and Durability.
Total integration of everything from the air handling to the exhaust after-treatment allows us to optimize every function to a degree no other engine manufacturer can match.
Every element has been designed and manufactured to optimize fuel economy, performance, reliability and durability while delivering the lowest operating costs of any engine in its class.
Better Performance. Ratings range from 400-600 hp (298-447 kW) with up to 2050 lb-ft (2779 n•M) of peak torque.
These include SmartTorque ratings that add 200 lb-ft of extra torque in the top two gears so Class 8 trucks can make it up steep grades with fewer downshifts.
Vocational ratings have additional torque in the lower gear ranges, where it's needed most.
Better Coverage For Better Confidence.
Cummins PowerSpec is an electronic tool that makes it possible to tailor the operation of Cummins engines in every on-highway application.

Have a durable forged steel crown coupled with a free floating aluminum skirt.
These pistons used the MAHLE patented shaker plate design to help cool the piston crown insuring greater survivability.
Single piece forged steel pistons that eliminate the need for skirt.
This simplifies the installation of the piston over the FERROTHERM design and at the same time insures superior endurance and performance offered by the FERROTHERM piston.
