We’re confident the X10 will offer our customers the right engine to help them meet their operational goals.”

Cummins X10 provides two ratings sets to offer customers flexibility when powering their vehicles. 

For heavy-duty applications, the X10 delivers up to 450 horsepower and 1,650 lb-ft of torque, providing customers with an optimal balance of power and reliability. 

For applications requiring a medium-duty package, the X10 delivers ratings up to 380 horsepower and 1,250 lb-ft of torque, ensuring strong performance across a variety of demanding applications.

Cummins said the new engine is built to perform in the toughest conditions and environments ensuring it stands up to the demands of the job. 

The OEM said it features a class-leading power-to-weight ratio. This offers customers a combination of exceptional performance and efficiency, designed to enhance productivity without weighing down vehicles.

Application Flexibility

Whether navigating city streets or tackling tough jobs in off-road environments, the X10 brings a sustainable, high-performing solution to each demanding application, according to Cummins.

For those needing flexibility in how power is used, the X10 provides increased Power Take-Off (PTO) capability of 590 lb-ft continuous and up to 664 lb-ft intermittent, providing vocational truck customers with enhanced power and versatility. This increased PTO output allows for more efficient operation of auxiliary equipment.

The X10 will come equipped with Cummins’ suite of digital technologies. These are designed to optimize performance, boost uptime and lower total cost of ownership. 

It features connectivity and instant access to a wide range of features and capabilities through Acumen, Cummins’ smart computing hardware and OEM first-fit solutions. 

Customers can leverage digital tools that enhance driver experience, including predictive capabilities (prognostics) and advanced over-the-air updates.

The engine pairs with transmission options including fully integrated powertrain offerings from the Eaton Cummins Joint Venture, ensuring smooth shifting and maximum uptime. 

When combined with Cummins Drivetrain and Braking Systems, including drivelines and axles, the X10 ensures that power is transferred efficiently to the wheels for maximum durability and control across diverse applications.

Cummins will launch the X10 in 2027, following extensive validation to meet customer needs, backed by millions of miles of planned on-road testing in real-world applications.
