Overview:

How do you make the industry-leading 15-liter engine even better? You talk to customers, spend thousands of hours on a dynamometer and run 9 million
real-world test miles to deliver better performance, reliability and support.

Reliability.

  • Optimized Emissions Control – Cummins Single Module™ aftertreatment has exceptional thermal efficiency, resulting in fewer regenerations, and meets OBD16 and GHG17 requirements.
  • Hardware Improvements – Includes a stronger turbo actuator, a larger-flow Exhaust Gas Recirculation (EGR) cooler and optimization through removal of several components.
  • Improved Oil Control – Up to 40 percent reduction in oil consumption through power cylinder improvements.
  • Collaboration with Chassis Builders – Each installation undergoes rigorous testing to ensure trouble-free operation.

Performance.

  • The Most Powerful Engine for Motorhomes – The X15, with up to 605 hp, now has better performance at lower rpm, for faster acceleration and more confidence when driving in the mountains.
    Stay in Control – The most powerful compression brake in the industry, with over 600 bhp, for confidence going down grades and better service brake life.
  • Better Acceleration, Faster Warm-Up and Stronger Engine Braking – The proven Cummins VGT® Turbo incorporates 15 years of technological improvements.
