At Rush Truck Centers, we strive to offer new products and solutions that can help customers do business and meet their goals. That is why we’re excited to offer the new S13 Integrated Powertrain in International LT® Series, RH™ Series and HX620 models to help shift what’s possible.
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.
*Comparing the 2017 GHG International A26 engine in a 2017 International LT with aero package to 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.
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) for on-highway applications. Vocational applications have the option of nine factory-installed PTOs, including REPTO and FEPTO without horsepower restrictions.
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.
6 Advantages of the S13 Integrated Powertrain
Available for International LT® Series, RH™ Series and HX620 models, the S13 Integrated Powertrain has a lot to offer for companies looking to streamline the overall operation of their fleets. We broke down the advantages it provides on The Long Haul blog to help International truck owners shift their idea of what’s possible for their business.
