Cummins will launch the next engine in the company’s fuel-agnostic series, the X10, in North America in 2026. The 10-liter displacement engine, named as part of the X engine family can replace both the L9 and the X12 used in motorhomes.
According to Cummins, the new X10 diesel will emit 75% less nitrogen oxide emissions than required at launch in 2026. The diesel version will be first available, with other versions following.
Cummins launched fuel agnostic engines, platforms using engine blocks and core components that share common design and are optimized for low-carbon fuels, in 2022.
“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.”
The X10 architecture uses a belt-driven, high output 48-volt alternator and aftertreatment heater solution optimized for increasingly stringent emission standards and will be scalable to other advanced combustion technologies.
The engine is equipped with Acumen, which provides digital connectivity and direct, immediate access to various applications and capabilities, Cummins said. These capabilities include over-the-air calibration and predictive service recommendations.
