Power Stroke, also known as Powerstroke, is a family of diesel engines that were produced by Navistar International from 1994 until 2010, and by Ford Motor Company since 2011. Along with its use in Navistar's medium-duty trucks and in the Ford F-Series (including Ford Super Duty trucks), applications include the Ford E-Series, Ford Excursion, and Ford LCF commercial truck, and South American production of the Ford Ranger.
From 1994 until 2010, Power Stroke engines sold by Ford were re-branded versions of Navistar International medium-duty truck engines. Since the 2011 introduction of the 6.7 L Power Stroke V8, Ford has designed and produced its own diesel engines. 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.
