powerstroke

Power Stroke is Ford Motor Company's designation for a family of diesel engines used in its pickup trucks and heavy-duty trucks. The line originated in the mid-1990s with the 7.3-liter Power Stroke, introduced for the Ford F-Series Super Duty in 1994. Produced for Ford under collaboration with International Harvester/Navistar for several generations, the Power Stroke engines were marketed for durability, high torque, and towing capability in Ford's heavy‑duty lineup.

Subsequent generations include the 6.0-liter (2003–2007), the 6.4-liter (2008–2010), the 6.7-liter (2011–present), and the 3.0-liter Power Stroke V6 turbo diesel (introduced for the F-150 in 2018). The 6.7-liter engine serves as Ford's main heavy-duty powerplant, while the 3.0-liter variant targets better fuel economy in lighter-duty trucks. Each generation brought advances in turbocharging, fuel-injection technology, and emissions controls.

Technically, Power Stroke engines are turbocharged diesel engines with electronic controls and modern fuel-injection systems. They power Ford's heavy-duty trucks such as the F-250, F-350, and F-450, and the later 3.0-liter variant was introduced for the F-150 to improve efficiency. The series has faced reliability and maintenance concerns over the years, particularly with emissions equipment and turbo components, which has influenced service approaches and consumer perception. The Power Stroke name remains a central part of Ford's diesel engineering and branding.
