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.
Born from a global collaboration of industry powerhouses, the S13 Integrated Powertrain is meticulously engineered to set a new standard.
Hear from the team that came together from around the globe to design, test and build the revolutionary International S13 Integrated Powertrain.
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.
Now powering the HX Series, the International S13 Integrated Powertrain demonstrates its capabilities on the job site.
Watch the recap video from the official S13 Integrated - HX Series launch at CONEXPO.
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.
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.

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.
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).
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.
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.
The S13 Integrated Powertrain is optimized for whatever the task may be. Available in the LT Series, RH Series, and the HX Series, the S13 Integrated is designed to take your business to the next level.
Several versions of the S13 Integrated Powertrain—each with a different horsepower rating—can be ordered with your International HX Series, allowing you to match the right engine to your specific application. All versions provide abundant torque at low RPM that is maintained through peak horsepower, giving drivers the muscle they need for the toughest jobs.
