By Tom Berg, Truck Editor | March 16, 2017

Daimler Trucks North America unveiled its upcoming Detroit DD8 diesel, the second in a series of medium-duty engines, at the NTEA Work Truck Show in Indianapolis.

Aimed at vocational truck applications, the DD8 is a 7.7-liter in-Line 6-cylinder model with a horsepower range of 260-350 horsepower and torque of 660–1,050 lb–ft. The DD8 expands on Detroit’s  4-cylinder DD5 introduced last year.

The DD8 will launch later this year with both engine and transmission power-take-off options and will initially be available in the Freightliner M2-106, 108SD and 114SD models, DTNA spokesman Nick Smith said. Trucks with DD8s should be in production in February.

Vehicles equipped with the midrange DD8 will feature Detroit Connect Virtual Technician remote diagnostic service. Virtual Technician helps fleets make informed maintenance decisions, so that they only service their vehicles when needed.

The Detroit DD8 targets a wide range of vocational applications including, construction, logging, plow and dump, utility/maintenance/repair service, pick-up and delivery, oil field, wrecking, refuse, fire/emergency and recreational vehicles, said Kary Schaefer, DTNA’s general manager, marketing and strategy.

In November, DTNA announced a $375 million investment to bring the manufacturing of both of its proprietary medium-duty engines to its manufacturing facility in Redford, Mich.. It now produces Detroit heavy-duty diesels, the DT12 automated manual transmission, and its Detroit axles.
