Revolutionary New DD15(tm) Engine Now Available in Sterling(r) Trucks

ORLANDO, FLA. – Feb. 4, 2008 – Sterling Truck Corporation today announced that the groundbreaking new DD15(tm) engine is now available for order in Sterling(r) trucks. Ideal for on-highway applications and known for its impressive performance and fuel efficiency, the DD15 will be available in the heavy-duty Sterling Set-Back A-Line and Set-Back L-Line models.

The DD15 is the result of the largest investment ever made in the development of an engine by a manufacturer and is offered in output and torque variants from 455 hp to 560 hp and 1,550 to 1,850 lb/ft, including dual torque ratings for special applications. The engine is currently on display in a Set-Back A-Line truck at the Technology and Maintenance Council (TMC) Annual Meeting in Orlando.

“The DD15 is a great addition to our component offerings,” said Richard Shearing, manager of product strategy for Sterling Truck Corporation. “It”s a reliable, powerful engine that pairs well with our Set-Back A-Line and Set-Back L-Line models for a complete transportation package for LTL and on-highway applications.”

The remarkable performance of the DD15 is due in part to its turbo compounding technology. At the rated speed of the DD15, the engine delivers up to 50 “free” horsepower without sacrificing fuel economy.

With its combination of exhaust gas recirculation and a particulate filter for reduced emissions, the DD15 is a global engine that is tailored to North America”s EPA “07 emissions regulations.
