Cummins introduces HELM 10-liter platform

Cummins Inc. has introduced the X10, a mid-bore engine designed to deliver heavy-duty performance in a midsize package. The 10 L X10 is a mid-bore heavy-duty engine that replaces  the L9 and X12 engine platforms. The company said the product delivers a new level of performance, durability and efficiency for heavy and medium-duty customers.

The X10 is part of the Cummins HELM platform, an approach that allows customers to choose the fuel type that best suits their needs. Alongside the X15 and B Series, the X10 provides customers with a power solution to meet their unique operational requirements.

“We’re incredibly proud to introduce the X10,” said Jose Samperio, vice president – North American On-Highway Engine Business. “Designed to replace the L9 and X12 platforms, the X10 brings robust capabilities, exceptional durability and unmatched versatility to customers looking for heavy-duty performance in a more compact, efficient package. We’re confident the X10 will offer our customers the right engine to help them meet their operational goals.”

The Cummins X10 will provide two ratings sets to offer customers flexibility when powering their vehicles. For heavy-duty applications, the X10 delivers up to 450 hp 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 hp and 1,250 lb-ft of torque.

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, designed to optimize performance, boost uptime and lower total cost of ownership. It features connectivity and instant access to a wide range of features 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 company said the X10 engine delivers a performance-driven solution, ensuring 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. In the meantime, it will be shown in the company’s booth at the 2025 Work Truck Week event at the Indiana Convention Center in Indianapolis, March 5-7.
