Cummins to Launch Next Engine in the Fuel-Agnostic Series in North America in 2026

Cummins Inc. will launch the next engine in the fuel-agnostic series, the X10, in North America in 2026. This engine, named as part of the X engine family, is positioned to replace both the L9 and the X12 to serve both medium and heavy-duty applications. It will be compliant with U.S. Environmental Protection Agency’s (EPA) 2027 regulations a full year early. The diesel version will be first available, with other versions for gaseous fuels introduced later. This 10-liter displacement product slots into Cummins’ product portfolio complemented by the B6.7 and X15 and will serve vocational, transit, pickup and delivery and regional haul customers.

“We are committed to advancing diesel technology while our markets and our customers need it to run their businesses. The new X10 has been designed drawing on our decades of experience as a leader in the medium and heavy-duty space,” said José Samperio, executive director, North America on-highway at Cummins Inc. “We have applied those learnings to ensure the product will perform for our customers and the important jobs they need to do every time.”
