S13-Powered HX Dump Trucks Arrive in Chattanooga — Ready to Work!

It won’t be long before HX becomes the truck of choice for dump truck operators across the region.

Why Choose International?

Let’s be real—International hasn’t been the go-to brand in the local dump truck market for a while. Competitors, especially Kenworth, have built a strong reputation for reliability, performance, and driver appeal. It’s almost like a club. So, why should T880 loyalists consider making the switch to International?

Because HX out preforms the competition. 

International is now part of Traton, a global powerhouse in truck manufacturing, with vast resources in engineering, production, and innovation. In 2024 alone, Traton sold over 334,200 vehicles worldwide and employs over 103,000 people across a global footprint. This backing has transformed International, enabling major product improvements, including the game-changing S13/T14 powertrain.

S13/T14 Powertrain: Power, Efficiency & Simplicity



S13/T14 has been a massive success since its introduction as the Super 13 by Scania in Europe in 2021. International brought it to North America in 2022, and it has quickly become one of the most fuel-efficient, reliable, and powerful engines in its class.

S13 Engine Highlights:

• Designed for the Future – Built from the ground up to meet EPA/CARB 2027 and Euro 7 emissions
• Efficiency & Power – A 12.7L engine with dual overhead cams, 4 valves per cylinder, and 23:1 compression ratio
• Clean-Burning Technology – Reduces particulate matter and NOx emissions with dual-stage DEF injection
• Six Ratings for Vocational Applications – Ranging from 400 HP / 1,450 lb.-ft torque to 515 HP / 1,850 lb.-ft torque (our trucks have the 515 HP version!)
• REPTO AND FEPTO

Less Complexity, More Reliability

S13 eliminates some of the most problematic components found in diesel engines:

• No EGR cooler
• No Diesel Oxidation Catalyst
• No seventh injector in the aftertreatment system
• No variable geometry turbocharger
