INTRODUCTION
The 2021-2024 Ford Expedition IV, with its 3.5-liter EcoBoost V6 engine producing 440 horsepower and paired with a 10-speed automatic transmission and 4×4, represented a significant step forward for Ford’s full-size SUV. Built on the U553 platform, this facelifted version addressed criticisms of earlier models, particularly regarding interior refinement and ride quality. This variant sat at the top of the Expedition range, offering a blend of power, luxury, and capability. It directly competed with vehicles like the Chevrolet Tahoe/Suburban, GMC Yukon, and Jeep Wagoneer.
Powertrain & Engine Architecture
The heart of this Expedition variant is Ford’s 3.5-liter EcoBoost V6 engine, internally designated as the third generation of the EcoBoost family. This engine utilizes direct injection, a twin-turbocharger setup, and variable valve timing (TI-VCT) to deliver both high power and respectable fuel efficiency. The engine code is a key identifier, though Ford often doesn’t publicly release specific codes for each year. The 10-speed automatic transmission (SelectShift) is a crucial component, offering a wide gear ratio spread for optimized acceleration and towing. This transmission is known for its smooth shifts and ability to keep the engine in its optimal power band. The engine’s architecture is a 60-degree V6, providing a compact footprint for installation in the large SUV chassis. The twin-turbochargers are positioned within the V, contributing to quicker spool-up and reduced turbo lag.
Driving Characteristics
The 440 horsepower and 691 lb-ft of torque provide substantial performance for a vehicle of this size. Acceleration is brisk, and the 10-speed transmission ensures the engine is consistently operating within its power curve. While not a sports car, the Expedition IV feels surprisingly agile for its size, thanks in part to the independent rear suspension. The 4×4 system provides confident traction in various conditions, and the SelectShift transmission allows for manual gear selection when desired. Compared to lower-output engine options (like the 3.5L naturally aspirated V6), this variant offers a significantly more engaging driving experience, particularly when towing or carrying a full load. The wide gear ratios of the 10-speed transmission are particularly noticeable when highway cruising, keeping engine RPMs low and contributing to improved fuel economy.
Equipment & Trim Levels
The 440 hp EcoBoost 4×4 SelectShift Expedition typically came standard with a high level of equipment. This included leather upholstery, heated and ventilated front seats, a premium sound system (often Bang & Olufsen), a large touchscreen infotainment system with navigation, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras included a panoramic sunroof, power-folding running boards, and a rear-seat entertainment system. Trim levels varied, but this engine was generally offered on the Limited, Platinum, and King Ranch trims, each adding progressively more luxury features.
Chassis & Braking
A key improvement in the Expedition IV was the switch to an independent rear suspension, replacing the solid rear axle found in previous generations. This significantly improved ride quality and handling. The front suspension utilizes a double wishbone setup with a transverse stabilizer bar. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. The ABS system is standard, along with electronic stability control. The chassis is a body-on-frame construction, providing a robust platform for towing and off-road use. The rear stabilizer bar is thicker than those found on lower trims, contributing to reduced body roll during cornering.
Market Reception & Comparison
The 2021+ Expedition IV with the 3.5 EcoBoost V6 received generally positive reviews. Critics praised the improved interior, comfortable ride, and powerful engine. Fuel economy, while not exceptional, was considered reasonable for a vehicle of this size. Compared to the naturally aspirated V6 models, the EcoBoost variant offered a substantial performance upgrade, but at a higher price point. Reliability has been generally good, although some owners have reported minor issues with the infotainment system. The EcoBoost engine, while powerful, requires premium fuel for optimal performance.
Legacy
The 3.5 EcoBoost V6-powered Expedition IV has established itself as a reliable and capable full-size SUV in the used car market. The 10-speed transmission has proven to be durable, and the EcoBoost engine, while complex, has generally held up well over time. These models continue to be sought after by buyers needing a spacious, powerful, and well-equipped SUV for family transportation and towing. The independent rear suspension remains a significant selling point, providing a more comfortable and refined driving experience than older Expedition models.
