Introducing the International S13 Integrated Powertrain

At Silver State International, we strive to offer superior operating economy, stellar performance and a simple, easy-to-service design. With the new International S13 Integrated Powertrain, we not only shift what’s possible for the industry, but for our customers as well, as we move ahead on the path to a more sustainable future.

Up to a 15% Boost in Fuel Efficiency*

• The S13 engine can operate at low RPMs with high torque, which means less fuel consumed, while still delivering up to 515 horsepower and 1,850 lb.-ft. of torque.
• With new dual stage aftertreatment system, the heavy (40-50 pounds), expensive, 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.

Smooth Operation and Superior Performance

• Smoother and quieter driving experience
• Full torque available at only 900 rpm
• Wide gear ratio provides optimal efficiency and performance in flat areas and on hilly terrain
• New compression release brake ensures strong, secure braking power (up to 469hp at sea level) when descending

14-Speed Overdrive Transmission With Shift-On-The-Fly Capabilities

• The T14 Transmission’s overdrive 14th gear and direct drive 13th gear is optimized to deliver peak fuel economy during typical load
• Electronically controlled clutch actuator works in sync with engine for faster, smoother shifting experience
• Drivers do not need to stop and let the air recharge
• Uses an integrated oil to water coolant system that optimizes temperature regulation in both hot and cold environments

T14 Transmission Key Benefits:

• Deep low-end gearing and shifting smoothness, delivering the efficiencies of a direct drive, within an overdrive package

• 14 speed with 2 crawler gears offer heavy-load stability and low-speed maneuvering capabilities as well as consistent performance

• A lightweight, efficiently packaged and robustly designed gearbox

• Single countershaft transmission designed for simplicity and reliability

Easily Serviceable. Simple. Reliable

• 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 generated allows for extended service intervals, as well as the elimination of need for active regeneration cycle and the diesel oxidation catalyst.
