Introducing the Intenrational^® S13 Integrated Powertrain

Up To A 15% Boost In 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. Thanks to a new dual stage aftertreatment system, the heavy (40-50 pounds), expensive (approx. $2,500) and finicky EGR cooler is no longer needed to reduce emissions. Its absence helps the S13 be the lightest 13-liter diesel engine providing maximum performance and efficiency.

Making the Shift: The T14 Transmission

The all-new, fully automated T14 is a 14-speed overdrive manual transmission that is optimized to deliver peak fuel economy performance in direct drive during typical load. Since it does not consume air during complicated maneuvers – like backing a trailer into a tight loading dock - there is no need to stop and let the air recharge. It also uses an oil-to-water coolant system to optimize temperature regulation in both hot and cold environments, which is one reason the T14 is able to achieve an unlimited gross combination weight rating (GCWR).

Next-Gen Aftertreatment

Each component can focus on 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 generate more power. Removing the EGR produces much less soot or particulate matter, allowing for extended service intervals and eliminating the need for active regens. The aftertreatment system provides a simple, reliable solution that is easily serviceable.
