As the trucking industry prepares for the next round of EPA emissions standards, Cummins has introduced the all-new 2027 X15, an engine built to deliver the power fleets expect while improving efficiency and simplifying emissions compliance. Designed for heavy-duty linehaul applications, the new X15 represents one of the biggest updates to the platform in years.
More Power, Same Legendary Reliability
The 2027 Cummins X15 produces up to:
- 605 horsepower
- 2,050 lb-ft of torque
That means operators won’t have to sacrifice performance to meet the latest emissions requirements. Whether you’re hauling heavy freight across the country or running regional routes, the X15 is engineered to keep productivity high.
Built for Better Fuel Efficiency
One of the biggest improvements is fuel economy.
Cummins redesigned the engine with features including:
- A dual overhead cam architecture
- Variable valve timing
- Updated air management
- A new variable geometry turbocharger
- A lighter engine block that offsets the additional aftertreatment weight
When paired with the optimized powertrain, Cummins says fleets can see meaningful fuel efficiency improvements while maintaining payload capacity.
Designed for EPA 2027 Compliance
The X15 was engineered specifically for the upcoming EPA 2027 emissions regulations. Instead of simply adding more emissions equipment, Cummins redesigned the platform to keep maintenance familiar while improving overall system performance.
Fleet managers can expect:
- Lower emissions
- Improved efficiency
- Familiar serviceability
- A proven engine platform with updated technology
