International S13 Integrated Powertrain

The International LT with the S13 Integrated Powertrain leads the on-highway aero category in fuel economy by at least 5%.*

Capable of up to 515 hp and 1,850 lb-ft of torque, the S13 Integrated consists of an engine, transmission and aftertreatment system designed together to maximize integration between systems while allowing each component to perform its function. The result is a new standard of efficiency, profitability and sustainability for our on-highway and off-highway customers.

Designed and developed from the ground up by a global dream team of engineers and proven over more than 4 million miles across a variety of terrains, the S13 Integrated is the last diesel powertrain we will ever produce—and, without question, our best.

*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.
