INTRODUCTION
The 2021-2024 Ford Expedition IV, with its 3.5-liter EcoBoost V6 engine paired with a 10-speed automatic transmission and 4×4 drivetrain, represented a significant step forward in the full-size SUV segment. Built on the U553 platform, this facelift brought updated styling, enhanced technology, and improved performance compared to the previous generation. The EcoBoost engine, a staple of Ford’s powertrain lineup, provided a substantial increase in horsepower and torque over earlier Expedition engines, making it well-suited for towing, hauling, and everyday driving. This particular configuration was offered across several trim levels, including XLT, Limited, and Platinum, with varying levels of standard and optional equipment.
Powertrain & Engine Architecture
At the heart of this Expedition variant 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 400 horsepower at 5000 rpm and 651 Nm (480.15 lb-ft) of torque at 2250 rpm. The engine employs direct fuel injection, a double overhead camshaft (DOHC) valvetrain with variable valve timing (TI-VCT), and a robust cast aluminum block. The twin turbochargers provide near-instant boost, minimizing turbo lag and delivering a broad, flat torque curve. The 10-speed SelectShift automatic transmission is crucial to harnessing the engine’s power effectively. This transmission offers a wide range of gear ratios, optimizing both acceleration and fuel efficiency. The transmission’s SelectShift functionality allows drivers to manually control gear changes when desired.
Driving Characteristics
The 3.5 EcoBoost V6 and 10-speed automatic combination in the Expedition delivers a markedly different driving experience compared to lower-powered engine options. Acceleration is brisk, and the engine provides ample power for merging onto highways and passing other vehicles. The 10-speed transmission keeps the engine in its optimal power band, resulting in smooth and responsive shifts. While not a sports car, the Expedition feels surprisingly agile for its size. The 4×4 system provides enhanced traction in various conditions, making it capable off-road, though it’s primarily designed for on-road comfort and capability. Compared to earlier Expedition models with naturally aspirated engines, this EcoBoost variant offers a significant improvement in both performance and refinement.
Equipment & Trim Levels
The 3.5 EcoBoost 4×4 variant was available on higher trim levels of the Expedition, typically starting with the Limited and extending to the Platinum. Standard features included leather upholstery, a power-adjustable driver’s seat, a large touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of advanced driver-assistance systems (ADAS) such as automatic emergency braking and lane-keeping assist. Optional extras included a panoramic sunroof, premium sound system, rear-seat entertainment system, and adaptive cruise control. The Platinum trim added even more luxury features, such as quilted leather seats, power-retractable running boards, and a 360-degree camera system.
Chassis & Braking
The Expedition IV utilizes a body-on-frame construction, providing a robust and durable platform. The suspension consists of an independent double wishbone setup at the front and an independent multi-link spring suspension at the rear, both incorporating a transverse stabilizer bar. This configuration delivers a comfortable ride quality, even on rough roads. 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 and control during emergency braking situations. The steering system is a rack-and-pinion setup with electric power steering, offering precise and responsive handling.
Market Reception & Comparison
The 2021-2024 Ford Expedition with the 3.5 EcoBoost V6 received generally positive reviews from automotive critics. The engine was praised for its power and refinement, while the 10-speed transmission was lauded for its smooth shifting and efficiency. Fuel economy, while not exceptional for a full-size SUV, was considered competitive within its class. Compared to the base engine option, the EcoBoost variant offered a significant performance upgrade, justifying the higher price tag for buyers who needed extra power. Reliability reports have been generally favorable, although some owners have reported minor issues with the infotainment system.
Legacy
The 3.5 EcoBoost V6 engine has proven to be a reliable and durable powertrain in the Expedition. As of 2024, these models are becoming increasingly popular on the used car market, offering a compelling combination of performance, features, and value. The 10-speed automatic transmission has also demonstrated good long-term reliability. While routine maintenance is essential, the EcoBoost engine is generally considered to be a robust and dependable unit. The Expedition IV, particularly the 3.5 EcoBoost 4×4 variant, has solidified its position as a leading contender in the full-size SUV segment, offering a compelling alternative to its domestic and import competitors.
