Who makes the Ford 6.7 diesel engine?
The Ford 6.7L Power Stroke diesel is a Ford Motor Company product, developed with substantial engineering input from International (Navistar).
Ford introduced the 6.7L Power Stroke for the 2011 model year to power its Super Duty lineup, and Ford continues to manufacture and support the engine as a cornerstone of its heavy-duty offerings. Navistar contributed to the engine’s development and early collaboration, but Ford leads production and ongoing development today.
Origins and collaboration
The 6.7L Power Stroke originated from a joint development effort between Ford and Navistar International (the company later known as International). The collaboration blended Ford’s drivetrain engineering with Navistar’s diesel technology expertise. The result is a Ford-branded diesel designed to meet the demands of heavy-duty pickup customers and commercial users.
Key collaboration points
Navistar’s role included engineering support and expertise in diesel propulsion, while Ford provided overall design direction, integration with the Super Duty platform, and the final assembly within Ford’s powertrain network. The partnership reflects the industry practice of combining specialized diesel know-how with Ford’s drive-train engineering and manufacturing capabilities.
Manufacturing and current status
Today, Ford manufactures the 6.7L Power Stroke engine within its own powertrain production network. While Navistar contributed to the engine’s early development, Ford maintains control over ongoing production, certification, and updates for the Super Duty lineup. Model-year updates continue to refine power, torque, and durability to meet emissions and customer needs.
What this means for buyers
For buyers, the 6.7L Power Stroke represents a Ford-branded diesel option backed by a collaboration with Navistar. It underpins Ford’s heavy-duty trucks with Ford’s service and warranty framework, delivering the capability customers expect from the Super Duty series.
