How much horsepower does a 6.7 L 8 cylinder turbo diesel engine have?
The latest Ford 6.7L Power Stroke V8 turbodiesel delivers up to 475 horsepower and about 1,050 lb-ft of torque. Older versions produced less power as the engine evolved and emissions rules tightened.
Understanding the engine and its ratings
The 6.7 L designation refers to the engine displacement. In Ford trucks, it denotes the Power Stroke V8 turbodiesel that powers the Super Duty lineup. This is an eight-cylinder engine (V8) built for heavy-duty use, and its horsepower figures have varied across model years as technology and emissions requirements changed. While commonly associated with Ford, it is distinct from the 6.7 L diesel used in other brands, such as inline-six configurations used by different manufacturers.
Current top rating and historical trend
Horsepower has risen in stages through the model years, with the current peak output reaching 475 hp and 1,050 lb-ft of torque. Earlier years featured lower numbers, reflecting updated calibrations and regulatory requirements.
To illustrate the progression across generations, here is a snapshot of approximate ranges by era:
- Early generations (roughly 2011–2016): about 400 hp and around 800 lb-ft of torque
- Mid-generation updates (roughly 2015–2019): about 440–450 hp and 860–925 lb-ft
- Latest offerings (2020–present): up to 475 hp and 1,050 lb-ft
These figures can vary by market, configuration, and emissions package. Some trim levels or special-tuning variants may show slightly different numbers on official spec sheets or dashboards.
What affects the power figure
Power output in real-world use is influenced by several factors beyond the base spec sheet:
- Engine calibration and emissions controls (diesel particulate filters, selective catalytic reduction)
- Altitude and ambient temperature, which affect air density and turbo performance
- Turbocharger boost pressure, intercooler efficiency, and fuel delivery timing
- Transmission choice and drivetrain setup (2WD vs 4WD) and any towing or drive modes
In practice, drivers may experience different horsepower readings depending on conditions, configuration, and whether the vehicle is in a normal or performance-tuned state.
Summary
The Ford 6.7 L Power Stroke V8 turbodiesel currently delivers up to 475 horsepower and 1,050 lb-ft of torque in its top configurations, with earlier years offering progressively lower power outputs as technology and regulatory requirements evolved. The exact figure depends on model year, trim, and tuning, but today’s peak represents the high end of the engine’s capability in heavy-duty trucks.
