Cummins announced their plans to confidently exceed upcoming EPA regulations, with the newest engine in their fuel-agnostic series scheduled for release a full year ahead of 2027 emission standards.
The X10 is set to debut first, with a diesel version leading the way and plans for other versions to follow soon after which will boast options for gaseous fuel sources.
Positioned as a replacement for two existing engines, this versatile offering is designed to provide maximum payloads from a lighter engine and serve both medium-duty and heavy-duty applications.
This new 10-liter powertrain is expected to complement the B6.7 medium-duty and X15 performance engines, providing a suite of solutions for a variety of vocational uses such as transit, pickup & delivery services or regional hauling needs.
In 2026, the X10 diesel engine is slated to launch. Reportedly, it will emit 75% fewer nitrogen oxide emissions than necessary, according to U.S. EPA regulations of 2027 – exceeding EPA regulations a year early.
According to a company news release, “Diesel will remain a critical technology for the commercial vehicle market for years to come, and Cummins will continue to support it.”
The engine will first be available in Europe and North America. It also will be developed for off-highway markets.
The X10 architecture uses a belt-driven, high-output, 48-volt alternator and aftertreatment heater solution optimized for increasingly stringent emission standards.
The fuel-agnostic platform will be scalable to other advanced combustion technologies.
Cummins’ fuel-agnostic platform offers customers a variety of engine versions that draw from the same basic foundation. Although located beneath the head gasket, components inside each motor will be consistent across all engines; however, various exterior parts and designs above this line will vary based on how they utilize different types of fuels exclusively.
The X10 engine, can pair with a range of transmission options for customized performance. Opting for Eaton Cummins Endurant will deliver unrivaled drivability and greater efficiency than ever before – allowing users to get more from their vehicles at every level of power.
Customers looking to further reduce their carbon emissions may also choose to use B20 biodiesel with their X10 engine.
The Acumen-equipped engine with digital connectivity, over-the-air calibration updates and predictive service suggestions will help keep fleets running smoothing.
Cummins is putting the pedal to the metal in 2026, with plans for a broad portfolio of medium- and heavy-duty products covering all client needs. At full speed ahead are brand new 15L natural gas engines – dubbed X15N by Cummins – as well as multi fuel B6.7s running on diesel, gasoline and propane or natural gas power sources.
