EFFICIENCY. PERFORMANCE. PRODUCTIVITY.

CUMMINS X15 EFFICIENCY SERIES (2024)

Reinforcing Cummins’ reputation for the longest service intervals in the industry, the X15 Efficiency Series scores the best “percent zero touch” and lowest “touches per thousand” uptime metrics. The onboard ADEPT™ (Advanced Dynamic Efficient Powertrain Technology) adapts to operating conditions in real time to enhance fuel economy. It also features a VGT Turbocharger and XPI Fuel System to boost efficiency and improve acceleration while delivering up to 500 hp (372 kW) and 1,850 lb-ft (2,508 Nm) of torque. A standard of efficiency and sustainability, the X15 Efficiency Series is one of the most efficient engines and designed to meet 2024 U.S. EPA and greenhouse gas emissions requirements.

CUMMINS X15 PERFORMANCE SERIES (2024)
For customers who prioritize performance above all, the X15 Performance Series combines power and rugged durability, outputting up to 565 hp (421 kW) and 2,050 lb-ft (2,779 Nm) of torque. The X15 Performance Series comes with the extended service intervals and VGT Turbocharger expected from Cummins while introducing advanced features like Acumen® remote diagnostics and over-the-air programming. The X15 Performance Series is also engineered with up to 600 braking horsepower. And designed to meet U.S. EPA and Phase 2 greenhouse gas emissions requirements.
CUMMINS X15 PRODUCTIVITY SERIES (2024)
The EPA 2024 X15 Productivity Series is the best of both worlds, sharing components with the Performance and Efficiency Series to deliver extraordinary power and fuel economy. With ratings up to 605 hp (451 kW) and 2,050 lb-ft (2,779 Nm) of torque, the X15 Productivity Series produces the most output capacity in the 15L category — enough muscle to take on the most demanding applications. It’s also well-connected, offering remote diagnostics, over-the-air programming and other digital service tools. Other features like the VGT Turbocharger and XPI Fuel System are optimized for seamless integration.
KEY FEATURES

VGT Power

The proprietary design of the VGT Turbo is four to six times stronger than previous designs for improved durability. This design also includes an impeller for rapid boost and improved braking.

 

Single High-Capacity ECM

Efficient, single ECM management of the engine and aftertreatment system provides  exceptional performance and fuel efficiency.

 

Cummins Aftertreatment System

A flow-through design provides better heat management for improved efficiency and increased ash capacity for fewer cleanings. This integrated system is up to 40% lighter and 60% smaller than some two-part systems.
