S13 Powertrain Fuel Efficiency

SETTING THE STANDARD

IN THE ON-HIGHWAY AERO CATEGORY

We went to great lengths to optimize efficiency in the International® LT® Series.
With cutting-edge aerodynamics and an innovative design, the S13® is built to
provideunparalleled performance for our customers.

THE FUTURE OF

POWERTRAIN ENGINEERING

Engineered in-house, the International® S13® Integrated Powertrain stands as a
landmark achievement in design and innovation. Every aspect, from the advanced
aftertreatment system to the cutting-edge T14 Transmission and the powertrain's
core components, has been meticulously reimagined.

With significantly lower fuel pressures and an innovative variable oil level system,
we've effectively minimized parasitic losses and dramatically enhanced efficiency.
The S13 Integrated exemplifies the remarkable expertise and ingenuity of our
engineering team. It transcends the conventional notion of a powertrain—delivering
a smarter and more fuel-efficient solution for drivers.

EXPLORE THE S13 INTEGRATED

*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.
