X15NTM

The most powerful natural gas engine Cummins has ever built. A broad range of engine ratings provides flexibility to perform across heavy-duty and vocational applications.

• Up to 500 hp and 1850 lb-ft of torque
• Built on 30+ years of natural gas experience
• Lighter than available 15-liter diesel engines
• More low-end torque than the ISX12N for improved startability and PTO operation
• Up to 10% fuel economy & GHG improvements over ISX12N with a equivalent rating and comparable duty-cycle
• Nearly 40% more engine braking power than ISX12N. Additional braking horsepower with the fan on

Back of Cab 175 DGE Fuel Storage

Unified integration with the X15N

• Provides an in-dash driver message center, Cummins engine ECM integration and telematics support
• Equipped with GreenLync™ technology
• System capacities of 60, 80, 95, 135 and 175 Diesel Gallon Equivalent
• Integrates with OEM cab extenders for improved aerodynamics (mounts within inches of cab)

Expanded digital and powertrain features now available with the X15N

• Hill Roll Out (HRO) - temporarily increase vehicle speed at the end of a downhill to efficiently cross upcoming terrain
• Predictive Gear Shifting (PGS) - enhances transmission gear selection using look ahead data to improve vehicle performance on hills
• Predictive Engine Braking (PEB) - uses look ahead data and improved transmission integration to better control vehicle speed on hills
• On-Ramp Boost (ORB) - identifies when a vehicle is on an on-ramp and allows for improved vehicle acceleration to assist with merging
