The International® S13 Integrated Powertrain
Advanced. Integrated. Undisputed.
Offering superior operating economy, stellar performance and a simple, easy-to-service design, the new International S13 Integrated Powertrain
will not only Shift What's Possible for the industry, but for our customers as we move forward on the path to more sustainable mobility.
The S13 is the lightest 13-liter diesel engine available in North America. It can operate at low RPMs with high torque which equates to
less fuel consumpiton while still delivering up to 515 horsepower and 1,850 lb-ft of torque. Available in: LT Series, RH Series, and HX Series 
Up to a 15% Boost in Fuel Efficiency*
- New double overhead cam design directly equates to less fuel being consumed.
- New Dual Stage Aftertreatment System eliminates need for heavy, expensive and finicky EGR cooler
- 100% of exhaust flow goes through the new simple, more reliable fixed-vane turbo charge for superior operating economy
Providing Stellar Performance for Drivers
- Smooth and quiet operation
- Full torque available at only 900 rpm
- Wide gear ratio delivers optimal efficiency in flat areas and performace on hilly terrain
- New compression release brake delivers strong, secure braking power (up to 469hp at sea level) when descending
All-New, Fully Automated T14 Manual Transmission
- 14-speed overdrive transmission that is optimized to deliver peak fuel economy performance in direct drive (13th gear) during typical load
- Electronically controlled clutch actuator works in sync with engine for faster, smoother shift performance
- Driver never needs to stop and let the air recharge
- Uses an integrated oil to water coolant system to optimize temperature regulation in both hot and cold environments
T14 Transmission Key Benefits:
- Deep low-end gearing and shifting smoothness, delivering efficiencies of a direct drive in an overdrive package
- 14 speed with 2 crawler gears
- A lightweight, efficiently packaged and robustly designed gearbox
- Single counter shaft transmission designed for simplicity and reliability
Simple, Easy-to-Service Design Providing Uptime
- Designed so that engine operates with zero cooled EGR during regular operation, resulting in generation of more power
- 100% of exhaust flow goes through the turbo allowing the use of a simple, more reliable fixed vane turbocharger
- Dual Stage Aftertreatment Design injects a first dose of DEF just downstream of turbo in evaporator tube and second dose inside the aftertreatment container
- Less soot or particulate matter results in extended service intervals as well as elimination of need for active regens
