Cummins is introducing the X10 mid-bore workhorse designed to deliver heavy-duty performance in a midsize package. The X10 replaces both the L9 and X12 engine platforms and delivers a new level of performance, durability and efficiency for heavy and medium-duty customers.
The X10 is part of the Cummins HELM (Higher Efficiency, Lower emissions and Multiple fuels) platforms, 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 while maintaining the performance and reliability for which Cummins is known. The new X15 lineup will be available with advanced diesel, natural gas and hydrogen fuel options, offering choice for customers with diverse needs. The X10 series will feature advanced diesel at launch, with plans to incorporate natural gas in the future.
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.
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’ comprehensive 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 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 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.
The engine can been seen in the Cummins booth at Work Truck Show at the Indiana Convention Center in Indianapolis, 5-7 March.
