Real-world results matter.
Based on regional customer operating data from Nov. '25 through May '26, the International S13 Integrated Powertrain continues to demonstrate strong fuel economy performance across a variety of routes, loads, and operating conditions.
Engineered as a fully integrated solution, the S13 combines:
✔ Fixed-geometry turbo technology
✔ No EGR cooler for reduced complexity
✔ Dual-stage aftertreatment technology
✔ T14 automated transmission with smooth, efficient shifting
The result is a powertrain designed to maximize efficiency, reduce soot, and meet 2027 EPA emissions standards.
Customer results shown are based on actual operating data. Fuel economy will vary based on route, load, driving behavior, vehicle configuration, weather, and other operating conditions.
