Powertrain & Engine Architecture
At the heart of the F-450 Super Duty IV DRW 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, intercooled diesel featuring a cast iron block and aluminum cylinder heads. The 2017-2019 iteration produced 450 horsepower at 2800 rpm and a substantial 935 lb-ft (1267 Nm) of torque at 1800 rpm. The engine utilizes a high-pressure fuel injection system, a common rail design, to deliver fuel directly into the cylinders. The overhead valve (OHV) valvetrain, while a more traditional design, proved robust and reliable. The turbocharger and intercooler work in concert to increase air density, boosting power and efficiency. Paired with this engine is the TorqShift 6-speed automatic transmission, a heavy-duty unit designed to handle the immense torque output. This transmission features a wide gear ratio spread, optimized for both towing and everyday driving.
Driving Characteristics
The F-450 Super Duty IV DRW 6.7L diesel automatic delivers a driving experience focused on capability rather than outright speed. The substantial torque output provides effortless acceleration, even when heavily loaded. The automatic transmission shifts smoothly and predictably, although it may not offer the same level of responsiveness as a manual transmission. The DRW configuration significantly enhances stability, particularly when towing large trailers. However, it also results in a wider vehicle, requiring more careful maneuvering in tight spaces. The ride quality, while improved over earlier Super Duty models, remains firm due to the heavy-duty suspension components. The gear ratios in the TorqShift transmission are tuned for maximizing towing performance, meaning the engine operates at relatively low rpm during highway cruising, contributing to fuel efficiency under those conditions.
Equipment & Trim Levels
The F-450 Super Duty IV Crew Cab Long Box was typically offered in several trim levels, including XL, XLT, Lariat, King Ranch, and Platinum. The base XL trim provided essential features, while higher trims added increasing levels of luxury and technology. Standard equipment on most models included air conditioning, power windows and locks, a basic audio system, and a rearview camera. Lariat trims and above often featured leather upholstery, heated and ventilated front seats, a premium sound system, and advanced driver-assistance features like blind-spot monitoring and lane departure warning. Optional extras included a navigation system, a sunroof, and various appearance packages.
Chassis & Braking
The F-450 Super Duty IV boasts a fully-boxed frame constructed from high-strength steel, providing a solid foundation for the vehicle. The front suspension utilizes a dependent spring design with an anti-roll bar, while the rear suspension employs a rigid axle setup with leaf springs. This configuration is designed to maximize payload and towing capacity. Braking duties are handled by ventilated disc brakes on all four wheels, with larger rotors at the rear to accommodate the increased weight. An Anti-lock Braking System (ABS) is standard. The DRW configuration provides a wider stance and increased braking surface area, further enhancing stopping power and stability.
Market Reception & Comparison
The 2017-2019 Ford F-450 Super Duty IV DRW 6.7L diesel automatic was generally well-received by critics and consumers alike. It was praised for its immense towing and hauling capabilities, robust construction, and comfortable interior (particularly in higher trim levels). Compared to the F-350 Super Duty, the F-450 offered a significantly higher payload and towing capacity, making it the preferred choice for those with the most demanding needs. Fuel economy, while respectable for a heavy-duty truck, was not a primary selling point. Reliability was generally good, although some owners reported issues with the diesel particulate filter (DPF) system, a common concern with modern diesel engines.
Legacy
The 6.7-liter Power Stroke V8 diesel engine has proven to be a durable and reliable powerplant, and the 2017-2019 F-450 Super Duty IV DRW continues to hold its value in the used car market. These trucks are sought after by those requiring a heavy-duty workhorse capable of handling demanding tasks. While newer Super Duty models offer even more advanced technology and features, the fourth-generation F-450 remains a capable and dependable option for those seeking a proven performer. Regular maintenance, including timely oil changes and DPF servicing, is crucial for ensuring the long-term reliability of this powertrain.
