DTNA Unveils New Detroit-Branded Powertrain

DETROIT — Daimler Trucks North America unveiled here a new Detroit-branded powertrain package, leveraging greater integration and a series of new technologies to offer what the company called its most fuel-efficient package yet.

The powertrain from Detroit Diesel Corp. features the DD15 engine, DT12 transmission and new axle offerings. It will be available for the Freightliner Cascadia Evolution in January and for the soon-to-be-offered Western Star 5700 later in 2015.

“If customers are looking for optimal fuel efficiency, this is the vehicle,” said David Hames, DTNA’s general manager of marketing and strategy.

He said the powertrain can increase fuel economy 5- 7% above the existing Evolution. During 2012, the company said it had achieved greater than 9 mpg during road trials.
