Powertrain & Engine Architecture
The heart of this F-250 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, intercooled diesel featuring a cast iron block and aluminum cylinder heads. The engine utilizes a high-pressure common rail fuel injection system, delivering fuel directly into the cylinders at extremely high pressures for optimized combustion. The valvetrain employs an overhead valve (OHV) configuration. The turbocharger, often a variable geometry turbo (VGT), provides increased power and torque across a wider RPM range. The six-speed TorqShift automatic transmission is a heavy-duty unit designed to handle the substantial torque output of the diesel engine. It features a wide gear ratio spread, allowing for both strong acceleration and efficient highway cruising. The transmission is electronically controlled, adapting shift points based on driving conditions and throttle input.
Driving Characteristics
The 6.7-liter Power Stroke V8 with the TorqShift automatic delivers a driving experience focused on capability and usability. While not as quick as gasoline-powered counterparts, the immense torque available from low RPMs provides effortless acceleration, even when towing heavy loads. The automatic transmission shifts smoothly and predictably, although it may exhibit some hunting for the right gear in certain situations, particularly when navigating hilly terrain. Compared to the 6.2-liter gasoline V8, the diesel offers significantly more torque, making it the preferred choice for demanding tasks. Compared to manual transmission equipped F-250s, the automatic provides ease of use, especially in stop-and-go traffic, but may sacrifice some driver control and fuel efficiency. The gear ratios are tuned for maximizing towing capacity and providing a comfortable driving experience at highway speeds.
Equipment & Trim Levels
The F-250 Super Duty IV offered a range of trim levels, with the 6.7-liter diesel/automatic combination available on most. Standard equipment typically included air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. Higher trim levels, such as Lariat, King Ranch, and Platinum, added features like leather upholstery, heated and ventilated seats, a premium audio system, navigation, and advanced driver-assistance systems. The Super Cab configuration provided additional rear seating space compared to the regular cab, making it suitable for carrying passengers alongside work equipment. Optional extras included a power moonroof, upgraded wheels, and various towing packages.
Chassis & Braking
The F-250 Super Duty IV features a robust chassis designed to withstand heavy loads and demanding conditions. The front suspension utilizes an independent coil spring setup with a trailing arm design, providing a comfortable ride while maintaining stability. The rear suspension employs a traditional leaf spring configuration, offering high load-carrying capacity. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard. Steering is accomplished via a hydraulic power steering system, offering a responsive and predictable feel. The frame is fully boxed, contributing to the truck’s overall strength and rigidity.
Market Reception & Comparison
The 6.7-liter Power Stroke diesel engine was widely praised for its power, torque, and refinement. Critics noted its ability to handle heavy towing and hauling tasks with ease. Fuel economy, while not exceptional, was considered reasonable for a heavy-duty truck of its size and capability. Compared to the gasoline-powered F-250 models, the diesel offered superior towing capacity and fuel efficiency under load, but came at a higher initial cost. Reliability was generally good, although some owners reported issues with the diesel particulate filter (DPF) and emissions control systems. The automatic transmission was well-regarded for its smoothness and durability.
Legacy
The 6.7-liter Power Stroke diesel engine has become a mainstay in Ford’s Super Duty lineup, continuing to evolve with each generation. The 2017-2019 F-250 Super Duty IV with this powertrain remains a popular choice in the used truck market, offering a compelling combination of capability, comfort, and reliability. While maintenance costs for diesel engines can be higher than those for gasoline engines, the longevity and resale value of these trucks often offset the increased expense. The TorqShift automatic transmission has also proven to be a durable and reliable unit, contributing to the overall long-term value of these vehicles.
