Cummins Spotlights its Next Gen X15 Off-Highway Engine at Bauma 2025, with Promises of Reduced Operating Costs and Simplified Integration
Cummins Inc. (NYSE: CMI) is exhibiting at Bauma 2025 this week in Munich, Germany, and placing a noteworthy focus on its next generation X15 Off-Highway engine platform.
Promising Original Equipment Manufacturers (OEMs) and end users a list of advancements over its predecessor, the newest addition to the company’s off-highway lineup is part of the Cummins HELM™ fuel agnostic engine platform and will power large scale construction and industrial equipment such as wheel loaders, cranes, excavators, air compressors and more.
“We’ve introduced a simplified clean sheet design that offers numerous benefits for our OEM partners and end users adopting the next gen X15 off-highway,” said Jonathon White, Vice President, Engine Business Engineering at Cummins. “Customers will see powerful performance and higher efficiency now in a lighter weight, smaller package, all while maintaining the steadfast durability Cummins has long been known for in construction applications.”
Reduced Operating Costs
Telematics, lower fuel consumption, easier maintenance, and long life to overhaul are all on the list of benefits new Cummins X15 customers should count on for improving their bottom line.
The latest off-highway X15 from Cummins delivers up to 10% better fuel economy compared to the prior X15 model, with comparable ratings and duty cycles. The X15’s high-efficiency fuel injection delivers precise fueling and combustion control at ultra-high pressures. Together, with the newly optimized HE550 Wastegate turbocharger, the system offers excellent transient response and altitude capability—built with new upgraded materials for durable and reliable performance.
Alongside improvements in fuel efficiency, the next gen X15 also promises cost savings related to routine maintenance.
New adopters can now expect up to 1000-hour service intervals from the X15, which means less overall maintenance required—period. Coupled with a better design, whereby its fuel filter and oil drain now both share the same replacement interval, common service items can occur simultaneously which results in less downtime and improved maintenance planning for fleets.
The X15 now also offers a maintenance-free breather and has no exhaust gas recirculation system, which collectively together will cut down on maintenance costs for new customers. Additionally, the new platform has been designed to provide a long life to overhaul resulting in potentially more productivity and stronger return on investment.
Capabilities to support remote monitoring and diagnostics, together with over-the-air (OTA) software updates, make maintaining engine health a less costly pursuit through the next gen X15’s telematics features.
Jobsite service professionals can take advantage of real-time alerts that are priority ranked and paired with Cummins engineering recommendations on how and when to service potential issues before they progress. When new engine calibrations are released from Cummins, the X15 OTA programming capabilities allow for secure software updates using cellular connectivity.
Both digital technologies, together, help reduce the need and cost for technician dispatches and unnecessary service stops, while ensuring more timely and accurate diagnostic reports and up-to-date engine calibrations. These digital capabilities require a compatible OEM gateway and participating telematics service provider.
Simpler Integration and Higher Power Density
In addition to lower total operating costs, installation of the next generation X15 into machine equipment will also be more straightforward.
With 20+ ratings that range 400-700 hp (298-522 kW) and peak torque up to 2360 lb.-ft. (3200 Nm), off-highway OEMs upgrading their offerings with Cummins’ next generation X15 will be able to deliver higher power and torque to customers with less weight and a smaller package size that resembles a 13-liter engine.
The X15 is equipped with a wide range of OEM integration options and application features, designed for easier installation and service. Modular component design further simplifies the integration process for off-highway equipment manufacturers, providing added flexibility to reach key connection points, while reducing the number of components by 30% in critical systems such as cooling and lubrication.
Meanwhile the flex-module aftertreatment with a new mixer design simplifies the installation, offering various installation configurations to better meet the needs of different applications. The elimination of the exhaust gas recirculation system (EGR) results in reduced cooling system requirements for machines. Additionally, the new X15 is available without aftertreatment to support varying regulations across countries, thereby simplifying integration across different regions.
“As the world's largest independent diesel engine manufacturer, our volume allows us to invest in new and innovative technologies to meet future requirements and emissions,” said Marina Savelli, Vice President, Engine Business Global Off-Highway Markets at Cummins. “In turn, we can bring exciting new innovations to the market and help power our OEM partners’ success well into the future.”
Fuel Agnostic Engine Platform
Cummins is developing a variety of solutions, including three brand new clean sheet engine platforms, designed to meet future emissions and CO2 norms globally. The B, L and X engine platforms will be compatible with a variety of current, and future, low and zero-carbon fuels, including natural gas, clean diesel, and hydrogen.
This means it’s possible to integrate these solutions, including the X15, into OEM equipment with limited proliferation by deploying Cummins HELM™ platforms which leverage common base engine hardware and unique fuel/air handling solutions to operate on varying fuel sources.
The ability to select different fuel types without requiring significant changes to the machine equipment makes X15 integration even more noteworthy. Customers who use Cummins HELM™ platforms can choose to power with clean diesel or biofuels today and move to a lower emissions alternative, like hydrogen, in the future.
