Cummins to introduce X10 version in 2026

The diesel version of the 10-litre engine will initially be launched in North America and Europe. The company plans to subsequently launch versions capable of operating on gaseous fuels, as well as versions for off-highway applications, such as the marine market.

The new engine is expected to offer improved fuel economy across the full range of engine loads.

During the product announcement in early February 2023, Cummins noted that the engine will meet the U.S. EPA’s 2027 regulations a year before the standards are introduced.

The US engine builder notes that the engine will slot into Cummins’ product portfolio complemented by the B6.7 and X15. The engine builder noted that it is expanding its gaseous fuels capabilities and would introducing a pure gas version of the X15, the X15N, as well as mono-fuel LNG and LPG-burning versions of the B.6 engine by 2026. It was not clear whether marinised versions of the alternative fuel burning engines would be introduced.

The new X10 engine will be equipped with Cummins engine connectivity module, Acumen, which will include over-the-air calibration and predictive service recommendations.

“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.”
