The 2011 model year overhauled the powertrain of the Ford F-250 Super Duty. Ford introduced its first in-house-designed and built diesel, the 6.7L Power Stroke V8, nicknamed the "Scorpion," replacing the International/Navistar 6.4L. The 6.7L used a turbocharger mounted in the engine valley with a reverse-flow layout, and it launched at around 390 horsepower and 735 lb-ft before a quick recalibration raised most 2011 trucks to 400 horsepower and 800 lb-ft. The gas side changed too: the 6.2L "Boss" SOHC two-valve V8 replaced both the 5.4L Triton V8 and the 6.8L Triton V10, producing about 385 horsepower in the Super Duty. The 6R140 TorqShift six-speed automatic was new for 2011 and paired with both engines. The 2011 trucks rode on a heavily updated version of the platform launched for 2008, so 2011 is best understood as a powertrain-driven era rather than a clean-sheet body. Over the run the 6.7L Power Stroke was upgraded repeatedly, reaching 440 horsepower and 860 lb-ft for 2015. The four-wheel-drive 2011-2016 Ford F-250 Super Duty kept a solid front axle with coil-spring suspension.

The 6.7L Power Stroke "Scorpion"
The 2011 Ford F-250 Super Duty introduced the 6.7L Power Stroke, Ford's first diesel engine designed and built in-house rather than by International/Navistar. Nicknamed the "Scorpion," it used an unusual layout with the turbocharger mounted in the valley between the cylinder banks and a reverse-flow design that placed the exhaust ports inboard and the intake ports outboard. It launched at about 390 horsepower and 735 lb-ft of torque, then a recalibration announced shortly after launch raised most 2011 trucks to 400 horsepower and 800 lb-ft, with early owners offered a free reflash. The 6.7L was upgraded repeatedly over its life; in this generation it reached 440 horsepower and 860 lb-ft of torque for the 2015 model year. The in-house 6.7L marked the end of Ford's reliance on outside diesel suppliers for the F-250.
The 6.2L Boss gas V8
On the gas side, the 2011 Ford F-250 Super Duty replaced both the 5.4L Triton V8 and the 6.8L Triton V10 with a single new engine, the 6.2L "Boss" SOHC two-valve V8, producing about 385 horsepower in Super Duty tune. The 6.2L had first appeared in the 2010 F-150 SVT Raptor and became the standard gas engine for the heavy-duty trucks. Consolidating the gas lineup into the 6.2L simplified the range that had previously split between the 5.4L V8 and the 6.8L V10.
Transmission, platform, and the front axle
The 2011 Ford F-250 Super Duty introduced the 6R140 TorqShift six-speed automatic, paired with both the 6.7L diesel and the 6.2L gas V8, replacing the earlier five-speed TorqShift. The 2011 trucks rode on a heavily updated version of the platform Ford launched for 2008, so the 2011-2016 era is best understood as a powertrain overhaul on an evolved body rather than a clean-sheet redesign; the next ground-up redesign came for 2017. The four-wheel-drive 2011-2016 Ford F-250 Super Duty continued to use a solid front axle with coil-spring suspension, the heavy-duty arrangement that distinguishes the Super Duty from the independently sprung F-150.
