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 throughout its production run, represents a significant leap forward in diesel technology for Ford. It utilizes a common-rail direct fuel injection system, delivering fuel at extremely high pressures for optimized combustion. The engine features an overhead valve (OHV) valvetrain, a robust design favored for its durability and low-end torque characteristics. A variable geometry turbocharger with an intercooler further enhances performance and efficiency. The six-speed TorqShift automatic transmission, a heavy-duty unit designed to handle the engine’s substantial torque output, provides smooth and reliable shifting. This transmission features a tow/haul mode, optimizing shift points for towing and hauling applications.
Driving Characteristics
The 6.7L Power Stroke V8 with the TorqShift automatic delivers a driving experience focused on capability and usability. While not as quick as lighter-duty trucks or those equipped with the gasoline engines, this combination provides ample power for towing heavy loads and navigating challenging terrain. The automatic transmission’s gear ratios are well-suited for both on-road cruising and off-road crawling. The engine’s peak torque of 1085 Nm (800.25 lb-ft) is available at a relatively low 1600 rpm, providing strong pulling power from a standstill. Compared to the gasoline engine options, the diesel offers significantly more torque, making it the preferred choice for those who regularly tow or haul heavy loads. Compared to manual transmission equipped models, the automatic provides ease of use, especially in stop-and-go traffic or challenging off-road conditions, but may sacrifice some fuel efficiency.
Equipment & Trim Levels
The F-350 Super Duty III was available in a variety of trim levels, including XL, XLT, Lariat, King Ranch, and Platinum. The 6.7L Power Stroke engine was available on most trims, but typically became standard on the higher-end Lariat and above models. Standard features on the XLT trim, which was a common configuration for this engine, included air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. Optional extras included leather upholstery, a navigation system, a premium sound system, heated and cooled seats, and a power-adjustable driver’s seat. The SuperCab configuration offered a second row of seating, increasing passenger capacity.
Chassis & Braking
The F-350 Super Duty III features a robust chassis designed to withstand heavy loads. The front suspension utilizes a dependent spring setup with an anti-roll bar, while the rear suspension employs a rigid axle with leaf springs. This configuration provides a comfortable ride while maintaining excellent load-carrying capacity. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control. The SRW configuration, as opposed to a Dual Rear Wheel (DRW) setup, offers a slightly narrower track width, making it more maneuverable in tight spaces.
Market Reception & Comparison
The 6.7L Power Stroke F-350 Super Duty was generally well-received by critics and consumers alike. It was praised for its powerful engine, capable towing and hauling capacity, and comfortable ride. Fuel economy, while not exceptional, was considered reasonable for a heavy-duty truck of its size and capability. Compared to the gasoline engine options, the diesel offered superior torque and fuel efficiency when towing heavy loads. Compared to other diesel-powered trucks in its class, such as the Ram 3500 and Chevrolet/GMC 3500, the F-350 Super Duty was often seen as a competitive offering, with a strong reputation for reliability and durability.
Legacy
The 6.7L Power Stroke engine has proven to be a durable and reliable powerplant, with many examples exceeding 200,000 miles with proper maintenance. The F-350 Super Duty III with this engine remains a popular choice in the used truck market, particularly among those seeking a capable and dependable work truck. While early versions of the 6.7L Power Stroke experienced some issues with the turbocharger and fuel injection system, these were largely addressed through recalls and updates. Today, these trucks represent a good value for those needing a heavy-duty truck without the cost of a new model. Regular maintenance, including oil changes, filter replacements, and coolant flushes, is crucial for ensuring the long-term reliability of this powertrain.
