S13 Powertrain: Superior Economy


LT with S13 Fuel Economy

Improved Fuel Economy:

  • 6-cylinder dual overhead cam with 4 valves per cylinder
  • Lower fuel injection pressures
  • Optimal fuel injection timing for most complete burn
  • Intake and exhaust manifolds to optimize air flow


Lower Operating Costs:

  • No Diesel Oxidation Catalyst (DOC)
  • No Exhaust Gas Recirculation (EGR) cooler
  • Fixed Geometry Turbo


THE INTERNATIONAL® LT® WITH THE S13® INTEGRATED POWERTRAIN LEADS THE ON-HIGHWAY AERO CATEGORY IN FUEL ECONOMY BY AT LEAST 5%.* LEARN MORE>


*The International® LT® with S13® Integrated Powertrain was tested head-to-head using TMC Type IV testing methodology against competitive on-highway aero models with comparable specifications: Freightliner Cascadia AeroX DD15, Kenworth T680 MX13, Volvo VNL760 D13. Testing proved the International LT with S13 Integrated Powertrain to be at least 5% more fuel efficient than these models. The International LT with S13 Integrated Powertrain uses up to 3.5% more DEF per gallon of fuel compared to comparable on-highway aerodynamic models.
