New Optional Axle Lubrication Management (ALM): The tandem rear axles feature an optional axle lubrication management (ALM) system that actively 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.ĭetroit Powertrain Product Overview Guide (Freightliner New Cascadia) Detroit Integrated Powertrain Brochure Detroit Connect Virtual Technician remote diagnostic system.

Lighter 6x2 Axle: The 6x2 axle configuration incorporates a non-driven tag axle on the tandem, reducing total weight (by 380 lbs) and the number of moving parts, delivering better fuel economy.

This means it can cruise in top gear longer, for better fuel efficiency. It pairs perfectly with the low RPM torque curve and direct drive transmission.

Faster 6x2 Axle Ratios: The 6x2 configuration boasts a 2.28 ratio, allowing the DD15 to turn lower RPMs with the truck cruising at the same speed.

A variety of faster axle ratios are available, ranging from 2.41 to 2.28.

Faster 6x4 Axle Ratios: The 6x4 configuration is available for applications requiring 4-wheel drive and superior traction.

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.

Transmission Benefits: The DT12's direct drive and over drive gearing, along with eCoast, are integrated with the downsped engine - which now idles at a lower 500RPM when off-throttle - for optimized fuel economy.

IPM4 refines the parameters of this technology, making the truck even more capable of utilizing its surroundings efficiently.

Intelligent Powertrain Management (IPM): The DT12 ® uses information from a topographical map to manipulate both engine and transmission functions, taking advantage of the truck's surroundings.

Super-Finished Gears: Tightly-spaced 12-speed gearing, now with 'super-finished' gears in the new DT12 ® available for the new Cascadia and Western Star 5700XE, improves low-speed maneuverability, making the Detroit ® Powertrain not only strong and efficient, but also smooth and safe to operate as well.

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.
