Perform When It Counts.

The DD5 is the most technologically advanced mid-range engine available in its market. Its features include:

  • Proprietary variable cam-phasing technology that reduces or eliminates regens for efficient aftertreatment system performance. Variable cam phasing keeps your aftertreatment system at the right temperatures during low-speed operation. That means fewer (or no) parked regens—and more time on the road. 
  • The DD5™ also has a smart, fuel-efficient design that makes the most of every gallon and lightens the load on the aftertreatment system. 
  • Its advanced common rail fuel system optimizes each injection event to minimize fuel consumption. 
  • A variable-speed fan and advanced cooling system providing shorter fan-on times for increased fuel efficiency
  • Simple, fixed-geometry, dual-stage turbo for performance, efficiency and reliability
  • An optional high-performance integrated engine brake
  • A B10 life of 400,000 miles
  • A robust rear gear train
  • The Detroit Connect Virtual Technician® remote diagnostic system to maximize uptime
  • Detroit provides a wide range of new vehicle engines compliant with EPA, CARB emissions, GHG, and OBD requirements. Please consult your local dealer to ensure the selection of a product that meets your specific needs.
