6.7 Powerstroke engine

Specifications

The Ford 6.7 powerstroke engine (V8 Turbo Diesel) is engineered for exceptional power, durability, and heavy-duty capability. Featuring a 90° V8 configuration, 32-valve OHV valvetrain, and 6.7-liter displacement, the engine combines a compacted graphite iron block with aluminum cylinder heads for strength and efficient operation. Its high-pressure common-rail direct-injection system and turbocharging help produce between 390 and 500 horsepower and up to 1,200 lb-ft of torque, depending on the model year and calibration. With a dry weight of approximately 970 lb, this engine is built to handle demanding towing, hauling, and commercial applications. 

Engine Variants

First Generation (2011-2014)

The first-generation Ford 6.7 powerstroke, introduced for 2011, marked Ford’s transition to designing its own diesel engine, known internally as the “Scorpion,” rather than relying on Navistar. It produced approximately 390–400 horsepower and 735–800 lb-ft of torque. The engine featured a unique “hot V” layout with reverse-flow cylinder heads and a Garrett GT32 dual-sequential turbocharger. Early models were known for issues involving turbocharger ceramic bearings, EGR systems, and the CP4 high-pressure fuel pump, making these components important considerations when evaluating early engines.

Second Generation (2015–2019)

The second-generation 6.7 powerstroke brought significant improvements in performance and durability, producing around 440–450 horsepower and 860–935 lb-ft of torque. Ford replaced the earlier dual-sequential turbocharger with a larger Garrett GT37 variable-geometry turbocharger (VGT), while also strengthening the engine block, upgrading the cylinder heads, and refining the fuel-system calibrated. Overall reliability improved compared with the first generation, although the CP4 high-pressure fuel pump and radiator seam leaks remained components worth monitoring.   

Third Generation (2020–Present)

The third-generation Ford 6.7 powerstroke received a major redesign focused on increased power, durability, and efficiency. Depending on configuration, output ranges from approximately 475–500 horsepower and 1,050–1,200 lb-ft of torque, with High Output variants introduced for 2023 and later models. Key updates include rugged steel pistons, a higher-pressure 36,000-psi fuel system, redesigned lightweight structural engine blocks, and a 10-speed TorqShift automatic transmission. High Output versions further enhance performance with water-cooled turbochargers and heavy-duty exhaust manifolds, making this generation substantially more capable for demanding towing and heavy-duty applications.
