The 2021-2024 Ford Expedition IV MAX with the 3.5 EcoBoost V6 and 4×4 SelectShift transmission represents a significant evolution in Ford’s full-size SUV offerings. Built on the U553 platform – a refreshed version of the fourth-generation Expedition – this variant aimed to deliver a blend of powerful performance, spaciousness, and advanced technology. The “MAX” designation signifies the extended wheelbase, providing a substantial increase in cargo volume, particularly crucial for larger families or those frequently transporting gear. This model occupied the upper echelon of the Expedition lineup, offering a premium experience compared to lower trims equipped with the standard 3.5L EcoBoost engine or rear-wheel drive.
Powertrain & Engine Architecture
At the heart of this Expedition MAX lies Ford’s 3.5-liter EcoBoost V6 engine. This engine, internally designated as a member of the EcoBoost family, utilizes a twin-turbocharged configuration to deliver a robust 400 horsepower at 5000 rpm and 651 lb-ft of torque at 2250 rpm. The engine employs direct fuel injection, optimizing combustion efficiency and power output. 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 and fuel economy. The engine’s architecture is longitudinal, meaning it’s mounted lengthwise in the chassis.
Paired with the engine is Ford’s 10-speed SelectShift automatic transmission. This transmission is designed to provide smooth and efficient gear changes, optimizing the engine’s power delivery across a wide range of driving conditions. The SelectShift functionality allows drivers to manually control gear selection when desired, offering a more engaging driving experience. The transmission is electronically controlled, utilizing sophisticated algorithms to adapt to driving style and terrain.
Driving Characteristics
The 400-horsepower EcoBoost V6 and 10-speed automatic combination delivers impressive performance for a full-size SUV. Acceleration is brisk, and the engine provides ample torque for towing and hauling. While not a sports car, the Expedition MAX feels surprisingly agile for its size, thanks in part to the well-tuned suspension and responsive steering. The 10-speed transmission contributes to a smooth driving experience, with minimal noticeable shifting. Compared to lower-powered Expedition trims, this variant offers a noticeable increase in responsiveness and capability. The 4×4 system provides enhanced traction in various conditions, making it suitable for light off-road use and inclement weather. However, the substantial weight of the vehicle (over 5,700 lbs) does impact handling and braking performance.
Equipment & Trim Levels
The 2021-2024 Expedition MAX 3.5 EcoBoost 4×4 typically came standard with a comprehensive suite of features, including a large touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a premium sound system, leather upholstery, heated and ventilated front seats, and a power liftgate. Higher trim levels, such as Platinum and Limited, added even more luxurious amenities, such as massaging seats, a panoramic sunroof, and advanced driver-assistance systems. Optional extras included a rear-seat entertainment system, adaptive cruise control, and a 360-degree camera system.
Chassis & Braking
The Expedition MAX utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension features an independent double wishbone design with a transverse stabilizer bar, while the rear suspension employs an independent multi-link setup, also with a stabilizer bar. This suspension configuration aims to balance ride comfort and handling. 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. The steering system is a rack-and-pinion setup with electric power steering, offering precise and responsive steering feel.
Market Reception & Comparison
The 2021-2024 Ford Expedition MAX 3.5 EcoBoost 4×4 was generally well-received by automotive critics. Reviewers praised its powerful engine, spacious interior, and advanced technology. Fuel economy, however, was a common criticism, as expected for a vehicle of this size and capability. Compared to other trims in the Expedition lineup, the EcoBoost 4×4 offered a significant performance upgrade but came at a higher price point. Its fuel economy was comparable to other full-size SUVs with similar engine configurations. Reliability reports have been generally positive, with few major issues reported.
Legacy
The 3.5 EcoBoost V6 engine has proven to be a reliable and durable powertrain in the Expedition MAX. While long-term maintenance costs can be higher than those of naturally aspirated engines due to the complexity of the turbocharging system, the engine has generally held up well over time. On the used car market, the 2021-2024 Expedition MAX 3.5 EcoBoost 4×4 commands a premium price compared to lower trims, reflecting its superior performance and features. Its spacious interior, powerful engine, and advanced technology continue to make it a popular choice for families and those seeking a capable and comfortable full-size SUV.
