X15 Off-Highway (2027)

Meet the Next Gen X15 Off Highway, the engine relentlessly taking on the challenges of today—and confidently ready for tomorrow.

The Next Gen X15 is designed to power the world’s most demanding applications in the most extreme environments, while meetingglobal emissions, delivering lowering operating costs and multiple fuel options.

Higher power density

Nearly 20 global ratings ensure unique equipment fits and reliable power for the most demanding applications in the most extreme environments​

• 400-700 hp (300-522 kW)​
• Up to 2360 ft-lb (3200 Nm) of torque​

Capable of handling 250 bar peak cylinder pressure to enable more torque, better startability in cold environments, and better capability for emission control.

15% higher peak torque in a package that’s smaller and lighter than the current 15 L engine​ with the potential to replace higher displacement engines with no impact on productivity​.

Simpler integration

The X15 is designed to make installation and service easier, no matter what type of equipment it powers.

• Modular component design simplifies the integration process for off-highway OEMs
• Added flexibility to reach key connection points
• The number of components has been reduced by 30% in critical systems such as cooling and lubrication
• Available without aftertreatment to support varying regulations across countries, thereby simplifying integration across different regions

Reduced operating costs

Lower fuel consumption, reduced maintenance, and long life to overhaul are all benefits X15 customers should count on for improving uptime and their bottom line.

• Up to 10% better fuel economy*
• Longer service intervals* (up to 1000-hours)
• No EGR system
• Fuel filter replacement interval synchronized with oil drain interval​ (ODI)
• Maintenance free open crankcase ventilation system
