the International® S13 Integrated Powertrain is meticulously engineered to set a new standard.

THE INTERNATIONAL® LT® WITH THE S13® INTEGRATED POWERTRAIN LEADS THE ON-HIGHWAY AERO CATEGORY IN FUEL ECONOMY BY AT LEAST 5%.*

SHIFT WHAT'S POSSIBLE

The International® S13® Integrated Powertrain is our most advanced, fuel-efficient and streamlined powertrain, available in the LT®, RH™, HX®, and HV™ series.

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

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.

ADVANCED. INTEGRATED. UNDISPUTED.​

A clean sheet of paper and decades of experience. That’s what the engineering team started with when they began work on the International® S13 Integrated Powertrain.  And this wasn’t any team. This was a dream team of engineers located literally all over the world.

It was thanks to this spirit of partnership, this deep collaboration between companies, that we were able to shift what’s possible and rethink, redesign and reinvent what an integrated powertrain can be.

UP TO A 15% BOOST IN EFFICIENCY*

The International S13 is Delivering superior operating economy.

Through exhaustive simulation work, a new cylinder and piston head design with maximum cooling properties was created. This new double overhead cam design directly equates to less fuel being consumed. But that’s not all. Thanks to the new Dual Stage Aftertreatment system, the heavy (40-50 lbs), expensive ($2,500 approx.) and finicky EGR cooler is no longer needed to reduce emissions. Its absence not only contributes to the International® S13 being the lightest 13-liter diesel engine available in North America, but it also means 100% of the exhaust flow goes through the new simple, more reliable fixed-vane turbo charger for maximum performance and efficiency.

*Comparing the fuel economy of the 2017 GHG International® A26 engine in a 2017 International® LT® Series truck with aero package to the fuel economy of the new International® S13 Integrated Powertrain in a 2024 International® LT® Series truck with the LT aero package and chassis enablers. Actual customer results may vary due to various factors, including but not limited to, truck specifications, weight of the vehicle, predictive features, environmental conditions, etc.

DELIVERING THE GOODS

The S13 Engine can operate at low RPMs with high torque which equates to less fuel consumed while still delivering up to 515 horsepower and 1,850 lb-ft of torque. This incredible engine brings undisputed economy through combustion efficiency, the reduction of friction and pumping losses, and through use of new integrated software and controls.

MAKING THE SHIFT

The all-new, fully automated T14 manual transmission was designed in-house from the ground up. It’s a 14-speed overdrive transmission that is optimized to deliver peak fuel economy performance in direct drive (13th gear) during typical load. The transmission has an electronically controlled clutch actuator that works in sync with the engine to deliver faster, smoother shift performance. Since it does not consume air during complicated maneuvers – like when you’re backing a trailer into a tight loading dock – the driver never needs to stop and let the air recharge. The T14 also uses an integrated oil to water coolant system to optimize temperature regulation in both hot and cold environments. This advanced feature is one reason why the T14  is able to achieve an unlimited Gross Combination Weight Rating (GCWR)

NEXT-GEN AFTERTREATMENT


Because there’s no EGR during regular operation, NOx must be treated a different way. To do this, the engineers developed an all-new Dual Stage Aftertreatment design that injects a first dose of DEF just downstream of the turbo in the evaporator tube and a second dose inside the aftertreatment container. Since a cooled EGR has been eliminated from the combustion chamber, much less soot or particulate matter is generated. This allows for extended service intervals and eliminates the need for active regens. In fact, the cleaner combustion cycle has so much less soot the engineers were able to eliminate the need for a diesel oxidation catalyst (DOC) in the aftertreatment system. Combined, the aftertreatment system provides a simple, reliable solution that’s easily serviceable.
