INTRODUCING THE INTERNATIONAL®
 S13 INTEGRATED POWERTRAIN

Watch the unveiling of the International® S13 Integrated Powertrain that took place at the Las Vegas Motor Speedway. See how the S13 Integrated will Shift What’s Possible for both the industry and our customers as we move forward on our path to sustainable mobility.

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 just any team. This was a dream team of engineers located around the globe. 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.

SHIFT WHAT’S POSSIBLE

Born from a global collaboration of industry powerhouses, the International S13 Integrated Powertrain is meticulously engineered to set a new standard.

MEETING OF THE MINDS

Hear from the team that came together from around the globe to design, test and build the revolutionary International S13 Integrated Powertrain.

A POWERFUL SHIFT FOR
THE VOCATIONAL MARKET

By combining the legendary strength of the HX Series with the stellar performance, enhanced serviceability and superior operating economy of the S13 Integrated Powertrain, International engineers were able to shift what’s possible and redefine what a severe service truck is capable of.

IT ALL COMES
TOGETHER

Now powering the HX Series, the International S13 Integrated Powertrain demonstrates its capabilities on the job site.

UP TO A 15% BOOST IN EFFICIENCY* FOR ON-HIGHWAY

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 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.

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.

*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.

A DRIVER'S ENGINE

Providing stellar performance for those behind the wheel.

Keeping the driver comfortable, informed and empowered has been a mantra at International® Truck for decades as part of our DriverFirst™ Philosophy. The International S13 Integrated Powertrain takes it a step further by offering a smooth and quiet operation with superior capabilities. In fact, full torque is available at only 900 rpm and the wide gear ratio means optimal efficiency on flatlands with the performance drivers crave on hilly terrain. And when descending, drivers can rely on the new compression release brake to deliver strong, secure braking power up to 469 hp (at sea level).

T14 Transmission Image

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)

UPTIME ABOVE ALL ELSE

A design that’s simple, elegant, and easy to service.

The entire powertrain was designed to allow each individual component – engine, transmission and aftertreatment – to focus on doing what it does best. Eliminating the EGR cooler is a prime example. Instead of trying to control NOx emissions inside the cylinder, the engine operates with zero EGR during regular operation, so it can focus on generating more power. Plus, no EGR during normal operations means 100% of the exhaust flow goes through the turbo allowing the use of a simple, more reliable fixed vane turbocharger.

Dual Stage Aftertreatment System

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.

  • Single Countershaft

    A single countershaft with helical gears lowers the overall weight of the unit without compromising the durability or performance of the transmission

  • Shift Actuators

    Shift actuator packaging was designed specifically for automated functionality (rather than adapted for a manual) allowing for more compact gearbox housing
  • Planetary Gears

    The planetary gear set eliminates the need for a dedicated reverse gear, shortening the gearbox and allowing for better packaging within the chassis
  • Variable Oil Level Upper Reservoir

    Oil is pumped to the reservoir under lower loads to reduce parasitic losses, allowing for the continuous lubrication of gears by the oil sprayers

TOUGH, DURABLE, AND STRONG

efficient combustion cycle

The S13 Integrated engineers paid special attention to the design of the combustion chamber and exhaust posts to enhance the performance and efficiency of the engine. Through exhaustive simulation work a new piston head with maximum cooling properties was created that when combined with a new double overhead cam design, directly equates to less fuel consumed.

transmission highlights

The S13 Integrated T14 Transmission features a revolutionary design. The reverse gearing is accomplished by using the planetary gears which helps reduce the overall weight and size of the unit, making room for chassis packaging and PTO.

Ready to work

Thanks to exhaustive engineering and choice of materials, the S13 Integrated Powertrain is remarkably light in weight. This helps the International® HX® Series achieve an outstanding payload capacity, along with improved fuel economy — attributes that can make a real difference to your bottom line. Plus, an International HX Series equipped with the S13 Integrated can be ordered with several different PTO options (including a dual option) installed directly at the factory and carrying the same warranty as the transmission.
