Easily recognized by the “V” designation on the ratings chart, Productivity Series ratings have a higher output capacity (up to 605 hp with 2050 lb-ft of peak torque) than any other engine in the 15-liter category. More important, the component set delivers superior responsiveness to throttle input – engineering-speak for plenty of muscle to get you rolling up to speed with a full load on hilly terrain.

The Best of Both Worlds.

2020 X15 Productivity Series ratings from 430-500 horsepower share a hardware set with the Cummins X15 Efficiency Series ratings. The higher output ratings from 565-605 hp use higher-capacity components from the X15 Performance Series ratings. This dual engineering strategy ensures that the X15 Productivity Series has the output required to meet power demands while optimizing fuel economy and operating costs. The rpm levels are set to match the job requirements of specific applications. Cummins continues to offer both Rear Engine Power Takeoff (REPTO) and Front Engine Power Takeoff (FEPTO) on X15 Productivity Series engines.

Improvements Across The Board.

The X15 ratings for 2020 offer upgraded turbocharger aerodynamics and a high performance EGR cooler for overall air handling improvements for greater efficiency throughout the system. Even the X15’s best-in-class engine braking has been improved with EGR Assist Braking. A more robust design means more reliable performance.
