The Ford Expedition IV MAX, specifically the variant equipped with the 3.5 EcoBoost V6 engine producing 375 horsepower and paired with a 4×4 automatic transmission, represents a significant iteration in Ford’s full-size SUV lineage. Produced from 2017 to 2021 (model year), this version of the fourth-generation Expedition (U553 chassis code) aimed to deliver a blend of powerful performance, substantial interior space, and capable towing capacity. The “MAX” designation indicates an extended wheelbase, providing increased cargo volume behind the third row of seats, catering to families and those requiring significant hauling capabilities. This particular configuration occupied a premium position within the Expedition lineup, offering a step up in performance and features compared to the base 3.5L naturally aspirated V6 models.
Powertrain & Engine Architecture
At the heart of this Expedition variant lies the 3.5-liter EcoBoost V6 engine. This engine, part of Ford’s EcoBoost family, utilizes a twin-turbocharged configuration to deliver a substantial increase in power and torque compared to naturally aspirated engines of similar displacement. The engine employs direct fuel injection, optimizing combustion efficiency and contributing to improved fuel economy. The valvetrain features a Double Overhead Camshaft (DOHC) design with Twin Independent Variable Camshaft Timing (Ti-VCT), allowing for precise control of valve timing to maximize performance across the engine’s operating range. The 10-speed automatic transmission, dubbed “SelectShift,” is a key component of this powertrain. This advanced transmission offers a wide range of gear ratios, enabling optimized acceleration, smooth shifting, and improved fuel efficiency. The transmission is electronically controlled and features a manual shift mode for driver engagement.
Driving Characteristics
The 375-horsepower EcoBoost V6, coupled with the 10-speed automatic, provides a noticeably more responsive and powerful driving experience compared to the base Expedition models. Acceleration is brisk, and the engine delivers ample torque for towing and hauling. The 10-speed transmission contributes to smooth and seamless gear changes, minimizing disruptions in power delivery. While not as fuel-efficient as the naturally aspirated V6, the EcoBoost engine offers a compelling balance of performance and economy. The 4×4 system provides enhanced traction in various driving conditions, making it suitable for inclement weather and light off-road use. The extended wheelbase of the MAX variant contributes to a comfortable ride, but it also results in a larger turning radius.
Equipment & Trim Levels
The 3.5 EcoBoost 4×4 MAX typically came standard with a generous array of features, including a leather-trimmed interior, tri-zone automatic climate control, a power liftgate, and a comprehensive infotainment system with a touchscreen display. Higher trim levels, such as the Platinum, added even more luxury features, such as premium leather upholstery, a panoramic sunroof, and advanced driver-assistance systems. Optional extras included a rear-seat entertainment system, adaptive cruise control, and a premium sound system.
Chassis & Braking
The Expedition IV MAX utilizes a body-on-frame construction, providing a robust and durable platform. The suspension system consists of an independent front suspension with double wishbones and an independent multi-link rear suspension. This setup aims to deliver a comfortable ride while maintaining good handling characteristics. 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 during emergency braking situations.
Market Reception & Comparison
The 3.5 EcoBoost 4×4 MAX Expedition received generally positive reviews from automotive critics. The engine was praised for its strong performance and smooth power delivery, while the 10-speed transmission was lauded for its responsiveness and efficiency. Critics also appreciated the spacious interior and ample cargo capacity of the MAX variant. Compared to the base V6 models, the EcoBoost version offered a significant performance upgrade, but at a higher price point. Fuel economy was generally considered acceptable for a vehicle of this size and capability, but it was not a standout feature. Compared to competitors like the Chevrolet Tahoe and GMC Yukon, the Expedition offered a compelling combination of features, performance, and value.
Legacy
The 3.5 EcoBoost engine has proven to be a reliable and durable powertrain in the Expedition. While some early EcoBoost engines experienced minor issues with oil consumption, these were largely addressed through design updates. The 10-speed automatic transmission has also demonstrated good long-term reliability. As a result, the 2017-2021 Expedition IV MAX with the 3.5 EcoBoost engine holds its value relatively well in the used car market. These models are often sought after by buyers who prioritize performance, towing capacity, and interior space.
