2024 Cummins X15 Efficiency Series (2017) X15 450 SA 1750

The highest fuel economy in the industry. The longest maintenance intervals, for lower maintenance costs. Increased uptime, for greater productivity and profits. Technology that accelerates service accuracy and speed. The biggest, most capable parts and service network in the industry. Being able to choose the best components and put them together. Top it off with the best resale value of any engine in the industry, and you’ve got a Total Cost of Ownership that puts you in front of your competition.

The value that Cummins is bringing to the trucking industry goes well beyond engine hardware.

Rookies drive like pros with ADEPT.™ ADEPT interacts with automated manual transmissions, adapting to operating conditions to help even novice drivers operate as efficiently as your most seasoned and efficient professional.

Features may include:

This turbocharger has variable geometry, for precision and responsiveness. The actuator is four to six times stronger than that of previous versions, for even better dependability. An enhanced design with a new impeller provides rapid boost and improved engine braking.

The XPI system delivers superior performance, regardless of engine rpm. Multiple injection events per cycle improve fuel efficiency and enable smoother, quieter operation. Steel plungers and diamond like coated roller tappets make this the toughest XPI fuel system to date.

A flow-through design offers better heat management, for improved efficiency. Increased ash capacity means fewer maintenance events. And it’s up to 40 percent lighter and 60 percent smaller than two-part systems.

These filters protect against corrosion and contaminants that can cause performance issues. The Fleetguard LF 14000NN lube filter provides less restriction, for faster flow and better cold-start capability, while still trapping nearly 99 percent of particles down to 4 microns.

The robust ECM manages the engine and aftertreatment system simultaneously, for optimum performance and fuel efficiency.

The most powerful engine brake in the industry offers up to 600 bhp, adding control on downhill grades, and helping reduce service brake wear, downtime and replacement costs.

VAM reduces driveline wear and improves fuel economy in bobtail and light-load driving conditions.

This feature uses telematics to wirelessly connect the engine to Cummins for rapid fault diagnosis. It enables continued operation without risk in most events, maximizing uptime.

Combustion’s hot. That’s bad for your oil. The X15 incorporates an enhanced piston design that reduces the transfer of heat to the oil, increasing both durability and oil-drain intervals.
