S13 Powertrain: Superior 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.
