The Power to Deliver.
You get the best of both worlds with horsepower and torque curves optimized for the most challenging applications. Whether you’re transporting raw materials in quad-axle dump trucks, moving 130,000 lbs down the interstate, or fall into a multi-purpose category, you’ll get access to whatever blend of power or efficiency you desire with the EPA2021 X15 Productivity Series.
The Best of Both Worlds.
2021 X15 Productivity Series ratings from 430-500 hp 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.
X15 Productivity Series ratings use the same engine hardware as the X15 Efficiency Series when choosing 500 hp or less. These ratings provide access to peak torque starting at 950 RPM and additional 300 rpm or engine operating range compared to the standard X15 Efficiency Series ratings. This extra rpm range provides longer access to peak power – helping you accomplish the most demanding tasks.

The X15 Efficiency series is optimized to deliver the power you need, with 430 hp to 605 hp and 1650-2050 lb-ft of peak torque – more than enough to get you off the line, down the road and up the steepest hill. But what’s really impressive is what happens when you crest the hill and take your foot off the accelerator. That’s when the most powerful engine brake in the industry kicks in, and you just ease on down the road.
