What engine does the F550 have?
The Ford F-550’s engine depends on the model year and configuration, but in recent production it is powered predominantly by a 6.7-liter Power Stroke turbo-diesel V8; gasoline-powered variants exist in older generations, though diesel is the standard for heavy-duty work.
The F-550 is a medium-duty chassis cab used in fleets and vocational applications. Over its history, Ford has offered several engine options to suit different payloads and service requirements. What you get today vs. a decade ago can vary, so it’s important to verify the exact build for a given vehicle.
Diesel powertrains
Diesel engines have been the backbone of the F-550 for torque-rich applications. The most common options across generations are listed below.
- 6.7L Power Stroke V8 Turbo Diesel — the current mainstream engine on most recent F-550 models, delivering strong torque for heavy hauling and vocational use.
- 6.0L Power Stroke Diesel — used on earlier F-550s (roughly mid-2000s to early-2010s); less common today but found in some fleets and pre-owned builds.
- 6.4L Power Stroke Diesel — present in some late-2000s to early-2010s configurations; now largely out of production but encountered in older units.
In practice, most buyers today will encounter the 6.7L Power Stroke as the standard diesel option, with older engines found primarily in used or legacy vehicles.
Gasoline powertrains
Gasoline engines have appeared in some F-550 configurations, though they are far less common in modern commercial service. The historical gasoline option most often referenced is:
- 6.8L V10 gasoline — used on older F-550 models (late 1990s to the early 2010s) for lighter-duty tasks or fleets that did not require diesel torque.
Today, diesel remains the primary choice for the F-550 in new production, with gasoline options typically associated with older stock or specific retrofits.
Important notes for buyers and operators
Engine choice can hinge on payload, use case, and maintenance plans. Always check the exact vehicle’s build sheet or window sticker (and confirm via the VIN) to confirm the engine and specifications for a specific F-550.
Summary
Summary: The Ford F-550’s engine lineup has evolved over time. Modern production centers on the 6.7L Power Stroke turbo-diesel V8 as the default for new builds, with older gasoline (6.8L V10) and diesel variants available in legacy models. For any given vehicle, verify the exact engine through official documentation to ensure it matches your needs.
