INTEGRATED DETROIT POWERTRAIN

Maximize fuel efficiency with powertrain integration

The Integrated Detroit® Powertrain delivers the performance and dependability you need to run your business efficiently. Detroit has designed, engineered and manufactured the engine, transmission and axles to work together seamlessly, providing the optimal powertrain solution for your business needs. The Integrated Detroit Powertrain is available in the Freightliner Cascadia.

Transmission

  • Integrated Communications Benefits: The DT12® transmission links engine to axles, and communicates with the DD13® and DD15® on an integrated electronics network to share damage-reducing information such as clutch overloading and driveline protection.
  • Super-Finished Gears: Tightly-spaced 12-speed gearing, now with "super-finished" gears in the new DT12®, improves fuel efficiency by reducing friction in the transmission.
  • Intelligent Powertrain Management (IPM): The DT12 uses GPS technology and information from a topographical map to manipulate both engine and transmission functions, taking advantage of the truck's surroundings. IPM refines the parameters of this technology, making the truck even more capable of utilizing its surroundings efficiently.
  • Transmission Benefits: The DT12's direct drive and over drive gearing, along with eCoast, are integrated with the downsped engine for optimized fuel economy.

Engine

  • Downsped Engines = Improved Fuel Economy: The DD13® and DD15® with downsped 425/450/455 and 1750 lb/ft rating deliver greater horsepower and torque at lower RPMs, allowing your truck to cruise at more efficient engine speeds. Lower engine speeds reduce friction and the number of fuel injections, dramatically improving fuel economy.
  • Increased Torque for Top Gear: IDP engine ratings deliver 1750 torque – more than typical long-haul ratings. This helps your truck stay in top gear longer where the engine runs most efficiently.

Steer Axle

  • Numerous Steer Axle Advantages: Detroit® steer axles offer rugged strength in a lightweight package, and integrate optimally with the other components. They are designed for the life of the axle, with multiple ratings available for tailored weight distribution.
  • Superior Maneuverability: The Detroit Powertrain's state-of-the-art steer axles provide a 55-degree wheel cut for remarkably nimble maneuvering. 
  • Needle Bearings Improve Durability: With needle bearings instead of bushings, they won't damage the king pins, and offer increased durability.

Tandem Rear Axle

  • New Axles Designed for Fuel Economy: To provide optimum efficiency and performance, the Detroit® Powertrain includes an all-new axle specifically designed to integrate with the downsped DD13, DD15 and DT12®, resulting in rock-solid reliability and durability.
  • Faster 6x4 Axle Ratios: The 6x4 configuration is available for applications requiring 4-wheel drive and superior traction. A variety of faster axle ratios are available, ranging from 2.16 to 2.28, or 2.64 for overdrive transmissions.
  • Axle Lubrication Management (ALM2): The tandem rear axles feature an axle lubrication management 2.0 (ALM2) system that regulates the oil level at the ring gear and friction-loss optimized pinion bearings to reduce friction and parasitic loss, extending gear life and further improving fuel efficiency.

Aftertreatment

  • 1-Box®: The 1-Box is a complete aftertreatment emissions system that combines the SCR catalyst, the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF) and Diesel Exhaust Fluid (DEF) all into one simple component.
