2017-2019 6.7

​Codenamed the Scorpion during its developmental stage, the 6.7L Power Stroke is Ford's in-house built diesel engine for the Ford Super Duty. Ford chose to design, engineer, and produce its own diesel engine to maintain profitability and a competitive edge in the growing diesel segment. This is the first Power Stroke not manufactured by long time partner, International Navistar. The absence of a partner seems to have given Ford an advantage over competitors, granting them the freedom to design an engine that fits their specific needs and the needs of their customers.
