Navistar has launched the International S13 Integrated Powertrain for the vocational market. The S13 Integrated Powertrain, developed in collaboration with the TRATON Group, demonstrates advancements in robustness, reliability and performance. This latest announcement showcases a continued commitment to customers by setting the foundation for the next generation of vehicles, technologies and comprehensive ownership solutions.
“The S13 Integrated Powertrain is the most advanced powertrain we’ve ever produced and the lightest vocational powertrain available on the market,” said Mark Stasell, vice president, Vocational Truck Business. “The S13 Integrated will benefit vocational customers by achieving stellar performance, simplicity and serviceability, and superior operating economy.”
This launch expands upon the current S13 Integrated Powertrain customer offering. Navistar first introduced the S13 Integrated Powertrain for the on-highway market in August 2022, available in the International LT and RH Series models.

Developed from a clean sheet design, the S13 Integrated Powertrain consists of three distinct components – an engine, a transmission and an aftertreatment system – all designed and developed concurrently to ensure maximized compatibility and integration between systems.
The S13 Integrated Powertrain maximizes performance and capitalizes on efficiency made possible through its modular design in global collaboration with the TRATON Group.
The 13-liter International S13 engine achieves advanced fuel efficiency and performance through a clean-burn combustion strategy and a reduction of friction and pumping losses. The S13 engine is Navistar‘s first engine designed with selective catalytic reduction (SCR) technology as the primary emissions reduction technology. The absence of an exhaust gas recirculation (EGR) cooler on this engine allows for nearly 100 percent of exhaust to flow to the fixed geometry turbocharger, equating to more power and improved engine performance. Additionally, the engine operates on low revolutions and high torque which equates to fewer fuel injections and less fuel consumption, delivering up to 515 horsepower and 1,850 lb-ft of torque.
