S13 Integrated Powertrain


The S13 Integrated Powertrain combines the truck engine, transmission, and aftertreatment. Shift what's possible.

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.

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 after treatment 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.

Stellar Performance

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).

Simple, Easy-to-Service Design

The entire powertrain was designed to allow each individual component – engine, transmission and after treatment – 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.
