Editor’s note: The 1980s was a transition period for engine technology in America. The iconic carburetor gave way to fuel injection. Cubic inches were out, and liter designations marked a new era for engines — one when power and fuel economy were no longer mutually exclusive. This modern engine age has featured some of the best innovation, technology, and performance yet.
#7 – Ford Powerstroke 6.7L
The diesels have joined the party!
Diesel technology has been around since the late 1890s, but the last 30 years (give or take) have seen the diesel’s rise as a viable option for the “Average Joe” American pickup truck owner. While the Cummins diesel helped pave the way for future diesel popularity, many credit the 7.3L Powerstroke engine for the proliferation of diesel-powered pickups we have today. The Powerstroke was originally manufactured for Ford by International Navistar, but Ford eventually brought production in-house following numerous warranty claims on the Powerstroke 6.0L engine.
Enter the Ford Powerstroke 6.7L in 2011.
The Powerstroke 6.7L was designed, engineered, and produced by Ford — the first Powerstroke engine not produced by International Navistar. Although part of the Powerstroke family, the 6.7L was a clean-sheet design and incorporated many unique features. The original 6.7L Powerstroke had a twin-scroll, sequential turbocharger and reverse-flow heads which placed the intake manifolds on the outside and the exhaust manifolds inside. This configuration is said to improve the thermal efficiency of the turbocharger, and its unusual look gave the 6.7L engine its codename: “Scorpion.” You can see some of the other innovative features of the engine by reading this comprehensive article by pickuptrucks.com
The first true Ford Powerstroke, the 6.7L has earned a reputation for good fuel economy, performance, and reliability. It not only put the Powerstroke name back in the good graces of diesel aficionados, but is also the most powerful engine to bear the name. It initially produced an impressive 390 horsepower, and 738 ft.-lbs. of torque when it debuted in 2011. Ford decided to replace the original turbo with a larger, Garrett GT37 variable geometry turbocharger in 2015, which increased power to 440 peak horsepower and 860 ft.-lbs. of torque.
The aftermarket has begun to catch up with the Powerstroke 6.7L. If you own a 6.7L-equipped Super Duty, here’s a sampling of some of the replacement parts and upgrades available:
