| Abstract: | The article focuses on Cummins' introduction of the X10 engine, a medium-bore powertrain within its fuel-agnostic HELM platform designed to replace the L9 and X12 engines. The X10 delivers up to 450 hp and 1,650 lb-ft of torque for heavy-duty applications, with a medium-duty variant offering 380 hp and 1,250 lb-ft, and features improvements in fuel economy, durability, and integrated braking power through its High Power Density (HPD) engine brake system. Sharing advanced technologies with the larger X15 engine, the X10 incorporates a lighter sculpted block, enhanced PTO capabilities, and meets EPA 2027 emissions standards. Limited production is expected in late 2026, with full production in 2027, and the engine is targeted at vocational uses such as local delivery, regional haul, transit buses, and emergency response vehicles.
