2011 Super Duty with the 6.7-liter Power Stroke diesel V-8 is rated at 400 horsepower and 800 pounds-feet of torque.
Codenamed the Scorpion during its developing stage, the 6.7L Power Stroke is Ford's internal built diesel engine for the Ford Super Duty. Ford chose to engineer, design, and produce its own diesel engine to stay profitable and competitive in the growing diesel segment.
This is the first Power Stroke not factory-made by long time partner, International/Navistar. The Ford-International partnership lasted almost 30 years. Like any new engine, many truck purchasers questioned the reliability despite its extensive durability testing. Fortunately, Ford seems to have triumphed with the 6.7L, which impresses in the departments of fuel economy, performance, reliability, and longevity.
Spectra Premium Industries has introduced an EGR Cooler for Ford 6.0L Powerstroke diesel engines. The exhaust gas recirculation (EGR) cooler on the Ford Powerstroke has a high premature failure rate due to the lack of maintenance on its diesel engine. Find out more here.
