Frequently asked questions

This 2027 X15™ will be manufactured at the Cummins Jamestown Engine Plant in New York.

The 2027 X15 platform is tested and proven across the globe. Extensive field and engineering testing within North America further proves the validation across multiple vehicle brands and applications.

The architecture uses a belt-driven, high output 48-volt alternator to provide power for an aftertreatment heater solution optimized for increasingly stringent emission standards. This technology allows for the reduction of NOx output across all operating conditions (cold start, light loads, no load conditions) without sacrificing fuel economy. 

At a system level, meaning engine and aftertreatment, weight is expected to remain neutral to the 2024 X15 system. 

Compared to the 2024 X15, customers can expect up to a 4% fuel efficiency improvement on the base engine with additional improvements available through powertrain features.

Customers can expect DEF consumption to be very similar to the 2024 X15 dependent on duty cycle.

Maintenance intervals and practices are planned to remain the same as the 2024 X15 with some improvements including cartridge style filters that reduce cost and environmental impact.

The 2027 X15™ will feature advanced digital capabilities to improve performance, reduce downtime, and lower costs. It offers connectivity options and digital solutions for the entire vehicle lifecycle, including predictive maintenance, over-the-air optimization, and enhanced service experiences.
