As with any new engine, potential truck buyers initially questioned the platform's reliability despite reports of extensive durability testing. Fortunately, Ford seems to have hit a home run with the 6.7L, which impresses in the departments of performance, fuel economy, reliability, and as we're slowly finding out, longevity. Over 500,000 6.7L Power Strokes were sold in the engine's first three years of production.

The 6.7L Power Stroke initially employed a unique single sequential turbocharger (SST) which features a dual compressor and single turbine setup affixed to a common shaft. The unit was replaced by a single Garrett GT37 variable geometry turbocharger (VGT) for the 2015 model year, subsequently increasing horsepower and torque in combination with additional upgrades. The SST returned to the Power Stroke for the completely revised 2017 model year Super Duty; torque reached an all time high at 925 lb-ft. Both horsepower and torque were once again increased for the 2018 model year, peaking at 450 hp and 935 lb-ft, respectively. Ford suggests that software adjustments, cylinder head improvements, and increased turbocharger boost are responsible for the increases.

Also unique is the engine's exhaust and intake manifold designs. As opposed to a tradition V engine, the intake and exhaust flows are reversed - the intake manifolds are located on the outer deck of the cylinder head and the exhaust manifolds exit directly into the engine valley where the turbocharger is mounted. The unique exhaust flow design is said to increase thermal efficiency of the turbocharger.
