International S13 Integrated Powertrain – The Next Step In Commercial Vehicle Technology

SMOOTH, POWERFUL, EFFICIANT

AND READY FOR EPA 2027

It should come as no surprise that the International® S13® Integrated Powertrain needed only minimal updates to meet 2027 EPA standards. It was, after all, engineered with a clean sheet of paper and a long-term vision that anticipated future regulations. As a result, 90% of the powertrain’s components carry over unchanged, which means your service tools, parts, technician training, and driver resources remain familiar, making the transition to the 2027 S13® Integrated Powertrain seamless. After years on the jobsite, the S13® Integrated Powertrain has proven to be a reliable workhorse. The engine, transmission, and aftertreatment system are designed to work as one, delivering robust power, smooth shifts and incredible efficiency.

UP TO A 15% BOOST IN EFFICIENCY*

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.

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).

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.

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® HV® and HX® Series achieve outstanding payload capacity, along with improved fuel economy — attributes that can make a real difference to your bottom line. Plus, an International 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.
