Detroit Diesel unveiled its new DD8 medium-duty engine at this week’s Work Truck Show in Indianapolis . The vocational 7.7 liter in-line six-cylinder diesel engine boasts a range of 260 hp to 350 hp and a torque range of 660 to 1050 lb. ft.

Production of the DD8 is set to begin next February, and the engine targets a wide range of vocational applications including recreational vehicles.

The DD8 expands the medium-duty engine platform Detroit debuted last year with the launch of the DD5, and Kary Schaefer, general manager of marketing and strategy for Daimler Trucks North America, says both the DD5 and DD8 will lead the industry in up-time and fuel efficiency.

“With these advantages, as well as ‘Virtual Technician,’ we are providing our customers a smart business solution,” she says. “We are confident that our customers will Demand Detroit in the medium-duty market just as they have in the heavy duty market.”

Initially the DD8 is available in Freightliner M2106, 108SD and 114SD models, and expanded availability is expected for Thomas Built Buses and Freightliner Custom Chassis Corp.
