Powertrain & Engine Architecture
At the heart of this F-350 variant lies Ford’s 6.7-liter Power Stroke Turbo Diesel V8 engine. This engine, designated with various internal codes depending on the specific year and calibration, is a robust and highly engineered powerplant. The 2020-2022 iteration produced 475 horsepower and a massive 1424 Nm (1050 lb-ft) of torque. The engine utilizes a high-pressure fuel injection system, common rail technology, and a variable geometry turbocharger with an intercooler to optimize combustion and power delivery. The engine’s architecture features a cast iron block, aluminum cylinder heads, and four valves per cylinder. The 10-speed TorqShift automatic transmission, introduced in recent years, is a crucial component, providing a wide gear ratio spread for optimal towing and fuel efficiency. This transmission replaced the previous 6-speed unit, offering smoother shifts and improved responsiveness.
Driving Characteristics
The combination of the high-output diesel engine and the 10-speed automatic transmission delivers a compelling driving experience. While not designed for outright speed, the F-350 offers substantial pulling power from low RPMs, making it ideal for hauling heavy loads. The 10-speed transmission keeps the engine in its optimal power band, even when climbing hills or towing. Compared to the gasoline-powered F-350 variants, the diesel offers significantly more torque, resulting in superior towing and payload capacity. Compared to earlier F-350 models with 6-speed transmissions, the 10-speed provides smoother shifts and improved fuel economy. The Super Cab configuration provides additional interior space compared to the regular cab, enhancing passenger comfort.
Equipment & Trim Levels
The 2020-2022 F-350 Super Duty offered a range of trim levels, with the 6.7L diesel/automatic combination available on higher trims like XLT, Lariat, King Ranch, and Platinum. Standard equipment typically included air conditioning, power windows and locks, a basic infotainment system with a touchscreen display, and a rearview camera. Higher trims added features such as leather upholstery, heated and ventilated seats, a premium sound system, navigation, and advanced driver-assistance systems like adaptive cruise control and lane-keeping assist. Optional extras included a fifth-wheel hitch, a gooseneck hitch, and various off-road packages.
Chassis & Braking
The F-350 Super Duty features a robust chassis designed to withstand heavy loads. The front suspension utilizes independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration provides a comfortable ride while maintaining excellent load-carrying capacity. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power even when towing. An Anti-lock Braking System (ABS) is standard. The Super Duty’s steering system utilizes a hydraulic power steering setup, offering a responsive and predictable feel.
Market Reception & Comparison
The 2020-2022 Ford F-350 Super Duty, particularly the 6.7L diesel/automatic variant, received positive reviews from automotive critics. It was praised for its powerful engine, smooth-shifting transmission, and comfortable ride. Compared to competitors like the Ram 3500 and Chevrolet Silverado 3500, the F-350 offered a competitive combination of capability, technology, and refinement. Fuel economy, while not a primary concern for heavy-duty truck buyers, was generally considered acceptable for the class. Reliability reports indicated that the 6.7L Power Stroke engine was generally reliable, although some owners reported issues with the fuel injection system and turbocharger.
Legacy
The 2020-2022 Ford F-350 Super Duty with the 6.7L diesel and 10-speed automatic represents a high point in Ford’s heavy-duty truck development. These trucks continue to hold their value in the used car market, reflecting their durability and capability. The 6.7L Power Stroke engine has proven to be a reliable and long-lasting powerplant, and the 10-speed transmission has significantly improved the driving experience. These trucks remain a popular choice for those who need a powerful and capable workhorse.
