INTRODUCTION
The 2021-2024 Ford Expedition IV 3.5 EcoBoost V6 4×4 SelectShift represents a significant evolution in Ford’s full-size SUV offerings. Built on the U553 platform, a refreshed version of the previous generation, this variant benefited from updated styling, enhanced technology, and a more refined interior. The 3.5L EcoBoost engine, paired with a 10-speed automatic transmission and a four-wheel-drive system, positioned this Expedition as a capable and comfortable hauler, suitable for both daily driving and long-distance travel. It sat near the top of the Expedition trim levels, offering a balance of luxury, performance, and utility.
Powertrain & Engine Architecture
At the heart of this Expedition variant lies Ford’s 3.5-liter EcoBoost V6 engine. This engine, designated as part of the EcoBoost family, utilizes direct fuel injection, a twin-turbocharger setup, and variable valve timing (TI-VCT) to deliver a potent combination of power and efficiency. The engine code is generally associated with the broader EcoBoost family, rather than a specific alphanumeric designation like older Ford engines. The twin-turbochargers provide increased airflow into the engine, boosting horsepower and torque. The 10-speed SelectShift automatic transmission, a crucial component of this powertrain, offers a wide range of gear ratios for optimized acceleration, towing, and fuel economy. This transmission allows the engine to operate in its most efficient range more often. The 4×4 system employs an electronically controlled clutch to engage the front wheels when traction is needed, providing enhanced stability in various driving conditions.
Driving Characteristics
The 380 horsepower and 637 lb-ft of torque produced by the 3.5 EcoBoost engine translate into strong acceleration and effortless cruising. While not as overtly sporty as some competitors, the Expedition offers ample power for merging onto highways, passing other vehicles, and towing substantial loads. The 10-speed transmission contributes to smooth and responsive shifts, and the 4×4 system provides confident traction in inclement weather. Compared to lower-powered Expedition variants (like those with the 3.3L V6), the EcoBoost model delivers a noticeably more engaging driving experience. The gear ratios are tuned to prioritize both acceleration and fuel efficiency, with lower gears providing quick off-the-line response and higher gears enabling relaxed highway cruising. The substantial weight of the Expedition is noticeable, but the engine’s torque output mitigates this, providing a feeling of robust power.
Equipment & Trim Levels
The 3.5 EcoBoost 4×4 SelectShift variant typically came well-equipped, often serving as a foundation for higher trim levels like Limited, Platinum, and King Ranch. Standard features generally included leather upholstery, heated and ventilated front seats, a power-adjustable driver’s seat, a large touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a premium sound system, and a suite of advanced driver-assistance systems (ADAS) such as automatic emergency braking, lane-keeping assist, and adaptive cruise control. Optional extras could include a panoramic sunroof, rear-seat entertainment system, power-folding running boards, and upgraded towing packages. Interior trim materials varied depending on the specific sub-trim, with higher trims featuring more luxurious appointments like wood trim and premium leather.
Chassis & Braking
The Expedition IV utilizes a body-on-frame construction, providing a robust and durable platform for towing and off-road capability. 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 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. The chassis is tuned to prioritize comfort and stability, rather than sporty handling, reflecting the Expedition’s intended role as a family-oriented SUV.
Market Reception & Comparison
The 2021-2024 Ford Expedition 3.5 EcoBoost 4×4 SelectShift received generally positive reviews from automotive critics. The engine was praised for its strong performance and smooth operation, while the 10-speed transmission was lauded for its responsiveness and efficiency. Fuel economy, while not exceptional for a vehicle of this size, was considered competitive within the full-size SUV segment. Compared to the base 3.3L V6 Expedition, the EcoBoost model offered a significant performance upgrade, justifying the higher price tag for buyers prioritizing power and towing capacity. Reliability reports have been generally favorable, although some owners have reported minor issues with the infotainment system and occasional turbocharger concerns.
Legacy
The 3.5 EcoBoost engine has proven to be a durable and reliable powerplant in the Expedition, and the 10-speed transmission has also demonstrated good long-term dependability. On the used car market, these Expedition variants hold their value relatively well, particularly those with lower mileage and well-maintained service records. The combination of spaciousness, capability, and technology continues to make the 2021-2024 Expedition a popular choice for families and those needing a versatile full-size SUV. The EcoBoost engine’s continued use in subsequent Expedition models underscores its success and enduring appeal.
