Detroit has designed, engineered and manufactured the engine, transmission and axles to work
together to lower your real cost of ownership.
The Detroit DD15
Engine can cruise at the same road speed at lower RPM's reducing fuel consumption and friction. This is made possible by integrating our fastest-ever tandem axle and made easy with our smooth-shifting DT12 Transmission
. The DT12 Transmission
links the engine to the axles.
