Cummins Unveils X10: A Powerful and Versatile 10-Liter Powerhouse Engine for 2027
Cummins Inc. has officially introduced the highly anticipated X10, a mid-bore heavy-duty engine designed to deliver robust performance, durability, and efficiency in a compact package. The X10 is engineered to replace both the L9 and X12 engine platforms, providing customers with a next-generation power solution that meets the evolving demands of heavy and medium-duty applications. As part of the Cummins HELM™ platform, the X10 offers fuel flexibility, allowing customers to select the fuel type that best aligns with their operational requirements. Alongside the X15 and B Series, this new engine reinforces Cummins’ commitment to reliability, innovation, and sustainability.
A New Benchmark in Mid-Bore Engine Performance
“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 provides customers with two distinct power ratings to ensure maximum flexibility:
- Heavy-Duty Applications: Up to 450 horsepower and 1,650 lb-ft of torque, offering superior power and reliability for demanding workloads.
- Medium-Duty Applications: Up to 380 horsepower and 1,250 lb-ft of torque, delivering balanced performance tailored to a wide range of operational needs.
Engineered for Maximum Durability and Efficiency
The X10 is built to excel in the harshest operating conditions. Featuring a class-leading power-to-weight ratio, it ensures high productivity without unnecessary weight, improving vehicle efficiency and handling. Designed for a variety of applications—including urban delivery, construction, emergency response, and vocational trucking—the X10 is versatile enough to tackle challenging environments while maintaining peak performance.
One of the standout features of the X10 is its increased Power Take-Off (PTO) capability, which reaches 590 lb-ft continuous and up to 664 lb-ft intermittent. This added power enhances versatility for vocational truck customers who rely on PTO-driven auxiliary equipment such as dump trucks, refuse haulers, concrete mixers, and utility vehicles.
The X10 also prioritizes fuel efficiency, leveraging advanced combustion technology to minimize fuel consumption while maximizing power output. This efficiency translates to reduced operating costs, making the X10 a cost-effective investment for fleet operators and independent truck owners alike.
Advanced Digital Technologies for Optimized Performance
To enhance uptime and lower total cost of ownership, the X10 comes equipped with Acumen®, Cummins’ cutting-edge smart computing hardware. Acumen® offers real-time diagnostics, predictive maintenance capabilities, and over-the-air updates, ensuring the engine remains in peak condition without requiring unnecessary downtime for servicing. With predictive analytics, fleet managers can proactively address potential issues before they lead to breakdowns, improving operational efficiency and reducing maintenance costs.
Additionally, Cummins’ integrated powertrain solutions—including fully automated transmissions from the Eaton Cummins Joint Venture—complement the X10, ensuring seamless power delivery and optimized fuel economy. When paired with Cummins Drivetrain and Braking Systems, including advanced drivelines and axles, the X10 enhances overall vehicle control, making it a game-changer for heavy-duty and vocational applications.
Sustainability and Emissions Compliance
As emission regulations continue to evolve, the X10 is designed to meet stringent 2027 EPA and CARB emission standards, reinforcing Cummins’ commitment to environmental sustainability. By integrating advanced exhaust aftertreatment technologies and reducing greenhouse gas emissions, the X10 supports fleet operators in achieving compliance with future regulatory mandates while maintaining superior performance.
Additionally, the X10’s compatibility with multiple fuel types under the HELM™ platform ensures that customers can transition seamlessly toward cleaner energy solutions, including low-carbon fuels and renewable diesel, without compromising operational efficiency.
Real-World Testing and Launch Timeline
To ensure its reliability and durability, the X10 is undergoing rigorous validation through millions of miles of on-road testing in real-world conditions. Cummins’ extensive testing process will guarantee that the engine meets the highest standards for performance, efficiency, and longevity before its official launch in 2027.
For those eager to see the X10 in action, Cummins will be showcasing the engine at Work Truck Show 2025 at the Indiana Convention Center in Indianapolis from March 5-7. Visitors can explore the latest advancements in Cummins’ powertrain technology and speak with experts about the benefits of integrating the X10 into their fleets.
A Future-Ready Power Solution
The launch of the X10 marks a significant milestone for Cummins and the commercial vehicle industry. With its blend of high performance, fuel flexibility, digital connectivity, and emissions compliance, the X10 is set to redefine expectations for mid-bore engines. Whether in heavy-duty trucking, municipal fleets, or specialized vocational applications, the X10 promises to be a powerful, durable, and future-ready solution for operators seeking the next level of efficiency and reliability.
