The International® s13® integrated powertrain

Shift What’s Possible with the S13® Integrated Powertrain

The S13® Integrated Powertrain is International®’s most advanced diesel solution—engineered for unmatched fuel efficiency, performance, and reliability. Available now at Cal Pacific Truck Center, this powertrain redefines what’s possible for on-highway and vocational fleets across California and the Southwest.

Whether you're spec’ing for long-haul, regional, or heavy-duty vocational applications, the S13 delivers up to 515 horsepower and 1,850 lb-ft of torque with a fully integrated engine, transmission, and aftertreatment system—all designed to work in perfect harmony.

Engineered for Efficiency, Built for Power

S13® Engine Highlights

• Double Overhead Cam Design: Maximizes cooling and combustion efficiency for lower fuel consumption.

• Clean Burn Technology: Operates at low RPM with high torque, reducing fuel use while maintaining power.

• No EGR Cooler: Eliminates complex components for improved reliability and turbo performance.

• Peak Output: Up to 515 hp and 1,850 lb-ft of torque.

This engine sets a new benchmark for diesel economy and uptime—perfect for fleets focused on total cost of ownership.

T14 Transmission: Smooth, Smart, Driver-First

• 14-Speed Automated Manual: Designed in-house for seamless shifting and optimal fuel economy.

• Direct Drive Efficiency: Peak performance in 13th gear, with overdrive available when lightly loaded.

• Compression Release Brake: Delivers up to 470 hp braking power for safe descents.

• No Air Recharge Needed: Electronically controlled clutch actuator eliminates downtime during tight maneuvers.

Drivers will appreciate the quiet operation, responsive shifting, and terrain-adaptive gearing.

Dual Stage Aftertreatment: Cleaner, Simpler, Smarter

• Zero EGR During Normal Operation: 100% exhaust flow through turbo for enhanced power.

• Two-Stage DEF Injection: Reduces NOx emissions without compromising performance.

• No Diesel Oxidation Catalyst (DOC): Cleaner combustion means less soot and longer service intervals.

• Extended DPF Life: No active regens required—DPF service intervals up to 650,000 miles at >8.2 mpg.

This system simplifies maintenance and boosts uptime, making it ideal for fleets that demand reliability.


 

Performance That Pays Off

• Fuel Economy Leadership: The LT® Series with S13® Integrated Powertrain leads the on-highway aero category by at least 5% in fuel efficiency compared to top competitors.

• Lightweight Design: Optimized materials and packaging increase payload capacity and reduce fuel costs.

• Factory-Installed PTO Options: Multiple configurations available—including dual PTO—installed with full warranty coverage.
