The Ford Power Stroke diesel engine is one of the most advanced and powerful turbodiesel engines on the market. You’ll find it under the hoods of Ford’s heavy-duty and full-size trucks.
The Power Stroke first arrived in 1994 with the 7.3-liter and is now in its fourth generation. It has steadily increased in power since its original launch. The original 7.3-liter delivered 210 horsepower and 425 pound-feet of torque.
The next generation of the Power Stroke Turbo Diesel was a 6.0-liter. Changes included an advanced fuel injection system and upgraded turbocharger technology.
The 6.4-liter version debuted in 2007 and was used in Ford trucks until 2010. It had twin turbochargers and upgraded technology, producing 350 horsepower and 650 pound-feet of torque.
The current generation is the 6.7-liter Power Stroke Turbo Diesel engine. While each of the previous generations came with changes and upgrades that made it better than before, the 2011 version was all new. Ford started from scratch with this engine. It has instant-start glow plugs to make trucks start faster in cold weather, and a new engine block of compacted graphite to make it lighter than ever.
Some of the 6.7-liter Power Stroke Turbo Diesel engine’s features include piston-cooling jets and high-pressure common-rail fuel injection. The 2024 high-output model can reach 500 horsepower and 1,200 pound-feet of torque.
It’s a 90-degree diesel V-8 with a single turbocharger, overhead valves, and in-block cams. The cooling system is a pressurized, series-flow system with an intelligent oil life monitor.
Some of the Power Stroke Turbo Diesel’s salient features include:
It has a biodiesel capability up to B20, which means it can handle a mixture of up to 80% petroleum diesel fuel and 20% biodiesel by volume.
This engine utilizes many technological advancements to make it strong, reliable, and capable. Some of these include the following.
The Power Stroke’s exhaust brake is incorporated into the turbocharger. You can engage the braking manually, or the system can do it automatically. This system is designed to give you better control when you’re towing and helps prevent brake wear and tear.
The exhaust brake has settings for Auto, On, and Off.
The smart charging alternator controls the voltage used when accelerating and decelerating, making the engine more efficient. The alternator uses a pulley and belt system to charge, exerting only the necessary amount of mechanical load as current.
This system decreases the amount of output the alternator uses, which means the truck uses less fuel, increasing its efficiency.
The stationary elevated idle control is a control system that allows the engine to idle at higher speeds when it is stationary. The system is integrated into the computer system and helps provide more power for accessories and auxiliary equipment when the truck is stationary.
A switch controls the system, so you can manually engage it when you like.
The Power Stroke Turbo Diesel engine has many components. Some of these are described below.
The Power Stroke features a compacted graphite iron deep-skirted engine block and aluminum cylinder heads to help reduce weight while maintaining high strength. The aluminum cylinder heads have dual water jackets for increased cooling and strength. The six head bolts for each cylinder make the seals tighter to maintain the cylinders’ integrity.
The inboard exhaust reduces the amount of produced exhaust and helps transfer the heat to the engine compartment. This exhaust design also improves throttle response and reduces noise and vibration.
The Power Stroke Turbo Diesel has a large turbocharger to increase airflow. This adds power and improves high-altitude performance.
The design features a single compressor wheel that forces air into the cylinders and compact variable nozzles to help deliver higher amounts of power more quickly.
The high-pressure common-rail fuel injections will deliver five fuel injections for each combustion cycle. This increases throttle response, helps improve performance, and reduces vibration, noise, and harshness.
The fuel injection tips are designed specifically for this engine, so they deliver more precise fuel atomization. This maximizes combustion, reduces noise and vibration, and lowers harmful emissions. The design also helps to reduce fuel deposit buildup on the valves.
You’ll find the 6.7-liter Power Stroke V-8 engine under the hood of the 2025 and 2026 Ford Super Duty trucks. These include:
It’s available for all Super Duty models, from the entry-level XL to the XLT, Lariat, King Ranch, and Platinum. Depending on the configuration, the engine gives these trucks the power to tow up to 38,000 pounds. You’ll need a gooseneck trailer and dual rear wheels for maximum towing power.
Now that you know more about the 6.7-liter Power Stroke Turbo Diesel engine, you can come to Planet Ford Dallas to test-drive a Super Duty truck with a Power Stroke under the hood.
