DD15 Engine Features

Hardcore Power and Fuel Economy

  • Unique Turbo Compound System recycles exhaust gases and boosts torque without sacrificing fuel.
  • Adds up to 50 free horsepower1 while providing up to a 5% fuel savings2 over other leading engines.
  • Innovative three-filter fuel system increases fuel efficiency and decreases emissions.

1 Effectiveness of turbo compound is based on load on the engine. The turbo compound returns horsepower back to the engine’s flywheel.
