Ford 6.7L Power Stroke Diesel Engine: Power Meets Precision

The 6.7L Power Stroke diesel engine—also known as the “Scorpion”—has been Ford’s flagship heavy-duty diesel option since 2011. Designed and built in-house by Ford, it was a game-changer after years of outsourcing Power Stroke production to Navistar. If you’re considering a Ford Super Duty pickup with a 6.7L engine, here's what you need to know about its performance, strengths, and areas to watch.

Ford 6.7L Power Stroke Diesel

✅ Pros of the 6.7L Power Stroke

1. Exceptional Power and Towing Capability

The 6.7L delivers brute strength for heavy-duty towing and hauling. Later model years boast best-in-class torque, making them ideal for fleets, RVers, and contractors.

2. Quiet and Smooth Ride

Ford prioritized refinement with this engine. It runs much quieter than its predecessors and rivals, even under load—making long hauls more comfortable.

3. Improved Fuel Efficiency

Compared to the older 6.0L and 6.4L, the 6.7L Power Stroke offers better miles per gallon, especially when paired with the 10-speed TorqShift transmission in newer models.

4. In-House Design and Upgrades

By developing the 6.7L internally, Ford had more control over quality and performance tuning. Regular updates (2015, 2017, 2020, 2023) brought improvements in fuel economy, emissions, and durability.

5. Strong Aftermarket Support

Tons of upgrade options exist—exhaust systems, turbo kits, tuners—great for enthusiasts who want more performance or efficiency (legally, of course).

❌ Cons of the 6.7L Power Stroke

1. Complex Emissions System

The DPF (diesel particulate filter), EGR (exhaust gas recirculation), and DEF (diesel exhaust fluid) systems are known to cause issues over time—especially for low-mileage or stop-and-go use.

2. Costly Repairs

While generally reliable, repairs can be expensive when they’re needed. Fuel system failures, particularly involving the CP4.2 high-pressure pump in older models, can lead to extensive damage.

3. Sensitive to Maintenance

Skipping scheduled maintenance (like fuel filter changes or poor-quality fuel) can cause expensive problems. It’s a high-performance engine that demands high standards.

4. Early Year Troubles

The 2011–2014 models had some turbo and emissions system quirks that were improved in later years. If buying used, aim for 2015 or newer for better reliability.

🔍 Is the 6.7L Power Stroke Right for You?

If you need a truck for serious work—towing equipment, hauling trailers, or racking up highway miles—the 6.7L is hard to beat. It combines performance, refinement, and durability, especially in newer model years. However, it’s not a “set it and forget it” engine; regular maintenance and premium fluids are non-negotiable.
