S13® Engine
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).

T14 Transmission
It’s a 14-speed overdrive transmission that is optimized to deliver peak fuel economy performance in direct driver (13th gear) during typical load. The transmission has an electronically controlled clutch actuator that works in sync with the engine to deliver faster, smoother shift performance.
Warranty
- Includes towing

14-speed with 2 crawler gears
Lightweight, efficiently packaged gearbox
Single countershaft transmission designed for simplicity and reliability.

Two DEF injectors
Dual-stage catalysts with upstream and midstream DEF dosing
System manages the regeneration during operation
DPF filter does not need to be cleaned/replaced until 650,000 miles at >8.2 mpg
Dual Stage Aftertreatment
An all-new Dual Stage Aftertreatment design that injects a first dose of DEF just downstream of the turbo in the evaporator tube and a second dose inside the aftertreatment container. Since a cooled EGR has been eliminated from the combustion chamber, much less soot or particulate matter is generated. This allows for extended service intervals and eliminates the need for active regens.
