Power Stroke, also known as Powerstroke, is the name used by a family of diesel engines for trucks produced by Ford Motor Company and Navistar International (until 2010) for Ford products since 1994. Along with its use in the Ford F-Series (including the Ford Super Duty trucks), applications include the Ford E-Series, Ford Excursion, and Ford LCF commercial truck. The name was also used for a diesel engine used in South American production of the Ford Ranger.
From 1994, the Power Stroke engine family existed as a re-branding of engines produced by Navistar International, sharing engines with its medium-duty truck lines. Since the 2011 introduction of the 6.7 L Power Stroke V8, Ford has designed and produced its own diesel engines. During its production, the Power Stroke engine range has been marketed against large-block V8 (and V10) gasoline engines along with the General Motors Duramax V8 and the Dodge Cummins B-Series inline-six.
