Detroit Diesel began production of the components making up the integrated Detroit Powertrain, the company announced at the Mid-America Trucking Show.

The integrated powertrain will include the Detroit DD15 engine, DT12 automated manual direct drive transmission and Detroit front and rear axles. Every component was designed to work together in an integrated system, says Detroit.

The integrated powertrain is available on the Freightliner Cascadia Evolution and the Western Star 5700XE.

The Detroit DD15 Engine is rated at 400 horsepower and 1,750 lb.-ft. of torque and was downsped to shift the usable torque range to lower engine speeds. This reduces friction losses, enhances fuel consumption and can improve reliability.

The DT12 automated manual transmission comes with Intelligent Powertrain Management which uses pre-loaded terrain maps and GPS to read the route ahead and adjust the shift points to improve function and efficiency.

The front and rear axles are offered in a 6x2 configuration with a 2.28 ratio that is designed to work with the downsped engine rating. The 6x2 Detroit axle configuration incorporates a non-driven tag axle on the tandem, reducing total weight by almost 400 pounds while a new 2.41 ratio in its 6x4 axle configuration is also available for applications requiring additional traction.
