The Future of
Powertrain Engineering
Engineered in-house, the International® S13® Integrated Powertrain represents a groundbreaking achievement in design and innovation. Every detail, from the aftertreatment system and advanced T14 Transmission to the powertrain’s core components, has been reimagined.
With lower fuel pressures and a variable oil level system, parasitic losses are minimized, and efficiency is improved. The S13 Integrated is a testament to the expertise and ingenuity of our engineering team. It is more than just a powertrain— it’s a smarter, more fuel-efficient solution for drivers.

5% Fuel Economy Guarantee
The International® LT® Series with the S13® Integrated Powertrain is the most fuel-efficient vehicle in the on-highway aero category.* We guarantee it will deliver at least 5% more in fuel economy.*
*The International® LT® with S13® Integrated Powertrain was tested head-to-head using TMC Type IV testing methodology against competitive on-highway aero models with comparable specifications: Freightliner Cascadia AeroX DD15, Kenworth T680 MX13, Volvo VNL760 D13. Testing proved the International LT with S13 Integrated Powertrain to be at least 5% more fuel efficient than these models. The International LT with S13 Integrated Powertrain uses up to 3.5% more DEF per gallon of fuel compared to comparable on-highway aerodynamic models.
