The Ford Expedition IV, produced from 2017 to 2021 (designated chassis code U553), represented a significant evolution in Ford’s full-size SUV offerings. Positioned as a premium family hauler, the Expedition IV aimed to deliver a blend of spaciousness, capability, and modern technology. Within the fourth generation lineup, the 3.5 EcoBoost V6 with 375 horsepower and a 4×4 automatic transmission was a popular, mid-to-high trim level, offering a balance between performance and fuel efficiency for buyers needing substantial towing capacity and all-weather capability. It sat above the base 3.5L naturally aspirated V6 and below potential higher-output EcoBoost variants offered in limited editions.

Powertrain & Engine Architecture
The heart of this Expedition variant is the 3.5-liter EcoBoost V6 engine, internally designated as a member of the third generation EcoBoost family. This engine utilizes a 60-degree V-engine configuration, featuring direct fuel injection and twin turbochargers. The twin-turbo setup, coupled with intercooling, provides a broad torque curve and minimizes turbo lag. The engine employs a double overhead camshaft (DOHC) valvetrain with Ford’s Ti-VCT (Twin Independent Variable Camshaft Timing) technology, optimizing valve timing for improved performance and efficiency across the RPM range. The 10-speed automatic transmission, branded “SelectShift,” is a crucial component, offering a wide range of gear ratios to keep the engine operating in its optimal power band. This transmission is known for its smooth shifts and contributes to both improved acceleration and fuel economy.
Driving Characteristics
The 375-horsepower EcoBoost engine delivers robust acceleration for a full-size SUV. While not as overtly sporty as some lighter vehicles, the Expedition IV with this powertrain provides ample power for merging onto highways, overtaking, and towing. The 10-speed automatic transmission is well-tuned, providing quick and decisive shifts. Compared to the base naturally aspirated V6, the EcoBoost offers a significantly more responsive driving experience. The 4×4 system provides enhanced traction in inclement weather and off-road conditions. The gear ratios are optimized for both on-road cruising and towing, with lower gears providing substantial torque for hauling heavy loads. The ride quality is generally comfortable, though the vehicle’s size and weight are noticeable in cornering.
Equipment & Trim Levels
The 3.5 EcoBoost 4×4 typically came standard with features like tri-zone automatic climate control, an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, and a suite of driver-assistance technologies including blind-spot monitoring and rear cross-traffic alert. Higher trim levels, such as the Limited and Platinum, added features like leather upholstery, heated and ventilated front seats, a panoramic sunroof, and a premium sound system. Optional extras included a navigation system, a rear-seat entertainment system, and adaptive cruise control.
Chassis & Braking
The Expedition IV utilizes a body-on-frame construction, providing a robust platform for towing and hauling. The front suspension features an independent double wishbone design, while the rear suspension employs an independent multi-link setup. This configuration aims to balance ride comfort with handling stability. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The anti-lock braking system (ABS) is standard, enhancing safety during emergency braking maneuvers. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The 3.5 EcoBoost 4×4 Expedition was generally well-received by automotive critics. It was praised for its powerful engine, smooth transmission, spacious interior, and impressive towing capacity. Fuel economy, while not exceptional for its class, was considered reasonable given the vehicle’s size and capabilities. Compared to the base V6 model, the EcoBoost offered a significant performance upgrade, justifying the higher price tag for buyers prioritizing power and responsiveness. Against competitors like the Chevrolet Tahoe and GMC Yukon, the Expedition IV was often seen as offering a more modern interior and a more refined driving experience.
Legacy
The 3.5 EcoBoost engine has proven to be a relatively reliable powertrain in the Expedition IV, although some owners have reported issues with the turbochargers and fuel injectors. Regular maintenance, including oil changes and spark plug replacements, is crucial for ensuring long-term reliability. On the used car market, the 3.5 EcoBoost 4×4 Expedition IV holds its value reasonably well, particularly well-maintained examples with lower mileage. Its combination of power, space, and capability continues to make it a popular choice for families and those needing a versatile full-size SUV.
