Is the Ford F-550 a gas or diesel?
The Ford F-550 is a diesel-powered medium-duty truck. In the current lineup, the standard engine is Ford's 6.7-liter Power Stroke turbo diesel V8, and gasoline options are not commonly offered on the modern F-550 chassis cab.
Where the F-550 fits in Ford's lineup
The F-550 sits in Ford's commercial lineup as a medium-duty chassis cab designed for body builders and specialty applications, such as service fleets, emergency vehicles, and commercial haulers. It emphasizes torque, payload capacity, and durability to support long-duty cycles and varied body configurations.
Diesel: why it's the default for most buyers
Diesel engines provide high torque at low rpm, which is essential for heavy hauling, towing, and powering mounted equipment. They also tend to offer longer fatigue resistance and better fuel efficiency under load, making them the practical choice for fleets that log extensive hours on the job.
Current engine options for the F-550
The latest U.S.-market F-550 chassis cabs are typically equipped with a diesel powertrain. A gasoline option is not standard in current production, and any gasoline offerings would be exceptional and region-specific. The typical configuration is:
- 6.7L Power Stroke V8 Turbo Diesel
Gasoline variants, if available at all, are rare and usually restricted to select markets or special-order programs; potential buyers should consult a local Ford Commercial dealer for exact specifications on a given model year or build.
What buyers should know
For fleets evaluating the F-550, diesel power aligns with the vehicle’s role: heavy payloads, frequent use, and compatibility with commercial body equipment. If a strict gasoline-powered build is a requirement, it is essential to verify availability and options with Ford or an authorized dealer for the specific configuration and year.
Summary
The Ford F-550 is, in its mainstream configuration, a diesel-powered vehicle featuring the 6.7-liter Power Stroke turbo diesel engine. Gasoline options are not common in current production, though niche or regional builds may exist. Always confirm the exact engine choice with the dealer when selecting a specific F-550 configuration.
