Powertrain & Engine Architecture
The heart of this F-350 variant is the 6.7-liter Power Stroke V8 diesel engine. This engine, designated with various internal codes depending on the specific year and calibration, is a turbocharged and intercooled design. The 2020-2022 facelift brought refinements to the fuel injection system, utilizing a common-rail direct injection system for improved combustion efficiency and reduced emissions. The engine features a cast iron block and aluminum cylinder heads, contributing to its durability. The turbocharger is a variable geometry unit, optimizing boost across the engine’s operating range. The ten-speed TorqShift automatic transmission, introduced in recent years, replaced the previous six-speed unit, offering closer gear ratios for improved acceleration, towing performance, and fuel economy. This transmission is electronically controlled and features a tow/haul mode specifically tuned for heavy loads.
Driving Characteristics
The 475 horsepower and 1424 lb-ft of torque delivered by this powertrain configuration translate to impressive real-world performance. While not as overtly quick as lighter-duty trucks, the F-350 excels in situations demanding substantial pulling power. The ten-speed automatic transmission helps keep the engine in its optimal power band, even when towing heavy trailers. Compared to lower-output engine options, such as the 6.2-liter gasoline V8, this diesel provides significantly more torque at lower RPMs, making it ideal for demanding work. Compared to other diesel variants, like those with higher horsepower ratings, this version strikes a balance between power and fuel efficiency. The 4×4 system provides enhanced traction in challenging conditions, making it suitable for both on-road and off-road use.
Equipment & Trim Levels
The Crew Cab configuration provides spacious seating for six passengers, making it a practical choice for work crews or families. Standard features typically included air conditioning, power windows and locks, a basic infotainment system with a touchscreen display, and a rearview camera. Higher trim levels, such as Lariat, King Ranch, and Platinum, added premium features like leather upholstery, heated and ventilated seats, a more advanced infotainment system with navigation, and a premium sound system. Optional extras included a sunroof, upgraded towing packages, and various driver-assistance technologies.
Chassis & Braking
The F-350 Super Duty utilizes a robust chassis designed to withstand heavy loads. The front suspension features a multi-leaf spring design with anti-roll bars, while the rear suspension employs a leaf spring setup. This configuration prioritizes load-carrying capacity and stability. 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 heavy-duty nature of the truck necessitates a robust braking system to manage its substantial weight.
Market Reception & Comparison
The 2020-2022 F-350 Super Duty with the 6.7-liter diesel and ten-speed automatic received generally positive reviews. Critics praised its powerful engine, smooth-shifting transmission, and impressive towing capabilities. Fuel economy, while not exceptional, was considered reasonable for a truck of its size and capability. Compared to competitors like the Ram 3500 and Chevrolet Silverado 3500HD, the F-350 was often lauded for its robust construction and user-friendly technology. Reliability reports have been mixed, with some owners reporting issues with the fuel injection system and turbocharger, while others have experienced few problems.
Legacy
The 6.7-liter Power Stroke diesel engine has become a mainstay in Ford’s Super Duty lineup, known for its durability and performance. The ten-speed automatic transmission has further enhanced the truck’s capabilities. In the used car market, these F-350s hold their value relatively well, particularly those that have been well-maintained and have a documented service history. The combination of power, capability, and a comfortable interior makes this variant a desirable choice for buyers seeking a heavy-duty pickup truck that can handle both work and personal use. Ongoing maintenance, particularly regarding the fuel injection system and turbocharger, is crucial for ensuring the long-term reliability of this powertrain.
