The Ford F-550’s current engine lineup centers on a 6.7-liter Power Stroke V8 turbo diesel as the primary option, with gasoline powerplants including a 6.2-liter V8 and, in some model years, a 7.3-liter V8 gasoline engine.
The F-550 is a heavy-duty chassis cab built on Ford’s Super Duty platform. Engine availability varies by model year, configuration (cab-and-chassis, box truck, or other body styles), and market. The following sections outline the typical options and how they have evolved over time.
Current engine options
Below are the primary engines Ford has offered for the F-550 in recent years. Availability can differ by trim, body style, and year.
- 6.7L Power Stroke V8 Turbo Diesel
- 6.2L V8 Gasoline
- 7.3L V8 Gasoline (available in select configurations and model years)
Engine choice affects towing capacity, payload, fuel economy, and maintenance costs. It’s important to verify the exact engine for a given vehicle through the build sheet or VIN.
Historical and alternative engines
Earlier versions of the F-550 used different powertrains, particularly before the current generation. This includes diesel and gasoline options from previous Ford powertrain families.
- 6.0L Power Stroke diesel
- 6.8L V10 gasoline
For older fleets or collectors, engine type can be a key distinguishing feature and may require different maintenance approaches.
Model-year variability
Engine availability changes with model year, regulatory requirements, and market. Always confirm the exact engine by checking the vehicle’s documentation or contacting a Ford dealer.
Why engine choice matters
The engine determines peak torque and horsepower, influencing towing capacity, payload, fuel economy, and maintenance intervals. Diesel engines generally offer stronger towing performance and better fuel economy on long hauls, while gasoline engines may have lower upfront costs and simpler maintenance for lighter duties.
Summary
The Ford F-550’s modern offerings center on the 6.7L Power Stroke diesel as the standard heavy-duty option, with gasoline choices including the 6.2L V8 and, in certain years, the 7.3L V8. Older generations used engines such as the 6.0L Power Stroke diesel and the 6.8L V10 gasoline. Always verify the exact engine for a specific vehicle, as availability varies by year and configuration.
