What size engine is in a F-450?
The F-450’s current engine lineup centers on two sizes: a 7.3-liter gasoline V8 and a 6.7-liter Power Stroke turbo diesel.
Ford’s Super Duty F-450 is built for heavy hauling and commercial use, and the engine choice affects maximum towing, payload, and fuel economy. The following outlines the two primary options available in recent model years, with typical outputs that can vary by year and configuration.
Current engine options
Below are the two engines most commonly found in recent F-450 models. Numbers are typical ranges for recent years; exact outputs vary by year and tuning.
- 7.3-liter gasoline V8 — about 430 horsepower and 475 lb-ft of torque; naturally aspirated; paired with a 10-speed automatic transmission; introduced in the current generation around 2020.
- 6.7-liter Power Stroke turbo diesel V8 — about 475 horsepower and 1,050 lb-ft of torque; turbocharged; paired with a 10-speed automatic; widely used on F-450 for towing heavy loads; output varies slightly by year and emissions configuration.
These figures illustrate the core trade-offs: the gasoline engine is simpler and typically cheaper to operate in light-duty use, while the diesel delivers substantially more torque for maximum towing and payload. Exact numbers can shift with model-year updates and regional specifications.
Historical context
Earlier Ford Super Duty generations offered different options, such as a 6.2-liter gasoline V8 or other configurations in some trims. The most common current pair for the F-450 remains the 7.3L gas and 6.7L Power Stroke diesel, but always verify the exact engine on a specific vehicle’s paperwork or window sticker.
Summary
In today’s Ford F-450 lineup, the engine size typically falls into two categories: a 7.3-liter gasoline V8 and a 6.7-liter Power Stroke turbo diesel. The gas option delivers about 430 hp and 475 lb-ft of torque, while the diesel delivers around 475 hp and roughly 1,050 lb-ft of torque. The best choice depends on your needs for towing capacity, payload, and running costs. Always check the exact specification for a given truck, especially if purchasing used or from a non-standard configuration.
