DETROIT, MI…Detroit Diesel Corporation (Detroit) already manufactures the industry’s most efficient and reliable engines, axles and transmission. Today, with the introduction of the new integrated Detroit™ Powertrain, featuring the Detroit DD15® engine, Detroit DT12™ transmission and Detroit axles, the Powertrain is now integrated to deliver even better performance to lower the Real Cost of Ownership for customers.
Available starting in January 2015 for the Freightliner Cascadia® Evolution and later in 2015 for the new Western Star 5700, the integrated Detroit Powertrain builds on the solutions developed by Daimler Trucks North America (DTNA) by providing state-of-the-art component communication that seamlessly work together.
“We know exactly what our customers want: Leading technologies integrated from one source that allows the customer to easily implement into their business model and improve uptime, safety and efficiency,” said David Hames, general manager, marketing and strategy for Daimler Trucks North America. “We are the only OEM who designs, engineers and manufactures a completely integrated Powertrain at this level of sophistication – marking another industry first for Detroit.”
Detroit is able to accomplish the level of performance and efficiency the integrated Powertrain provides by designing, engineering, testing and manufacturing everything under one roof. Every individual product was studied to make certain they were specifically tuned to work together to deliver maximum efficiency.
According to Brad Williamson, manager, engine and component marketing for Daimler Trucks North America, to create the integrated Powertrain, Detroit’s axle engineers developed a new axle ratio (and configuration) to match the engine rating. Engineers also tuned the transmission electronics to ensure all of the calibrations fit together perfectly to deliver the integration and performance customers demand.
New Rating, More Efficiency
The integrated Detroit Powertrain features the flagship DD15 engine, with new downsped rating of 400hp and 1750 lb/ft. The downsped rating enables the engine to turn at lower RPMs regardless of road speed, ultimately reducing fuel consumption and friction. Because it delivers the necessary torque at these low RPMs is the engine is able to deliver the power drivers demand.
“Downspeeding improves fuel economy by shifting usable power and torque to a lower RPM range,” said Williamson. “Because we understand how important driver retention is to the Real Cost of Ownership, Detroit engineers made sure to deliver a product that drivers will like.”
The proprietary Detroit Virtual Technician™ On Board Diagnostic System is also integral to the Powertrain. The DD15 features the 1-Box™ emissions package that combines DOC, DPF, SCR catalyst and DEF doser, creating an optimal solution for a variety of truck configurations. The DD15 also meets OBD13 and GHG14 standards.
