The 2021-2024 Ford Expedition IV MAX with the 3.5 EcoBoost V6 and 10-speed automatic transmission represents a significant evolution in Ford’s full-size SUV strategy. Built on the U553 platform, a refreshed version of the fourth-generation Expedition, this variant aimed to deliver improved performance, fuel efficiency, and interior refinement. The MAX designation, signifying the extended wheelbase, caters to buyers needing substantial cargo space and comfortable seating for up to eight passengers. This model year saw a substantial facelift, incorporating updated styling, enhanced technology, and a more powerful engine option.
Powertrain & Engine Architecture
At the heart of this Expedition MAX variant lies Ford’s 3.5-liter EcoBoost V6 engine. This engine, internally designated as the third generation of the EcoBoost family, utilizes direct injection, a twin-turbocharger setup, and variable valve timing (TI-VCT) on both intake and exhaust camshafts. The engine produces 400 horsepower at 5000 rpm and a robust 651 lb-ft of torque at 2250 rpm. The twin-turbochargers are designed to minimize turbo lag and provide a broad, flat torque curve. The 10-speed SelectShift automatic transmission, co-developed with General Motors, is a crucial component of this powertrain. Its wide gear ratio spread allows for both strong acceleration and efficient highway cruising. The transmission features fully automatic operation but also includes a manual shift mode for driver control. The engine’s architecture is a 60-degree V-configuration, contributing to a relatively compact engine bay layout.
Driving Characteristics
The 3.5 EcoBoost V6 and 10-speed automatic combination delivers a markedly different driving experience compared to lower-trim Expedition models. Acceleration is brisk, and the engine provides ample power for towing and hauling. The 10-speed transmission is generally smooth and responsive, although some drivers have noted occasional hunting for the optimal gear in certain driving situations. The gear ratios are optimized for both low-end torque and high-speed cruising. Compared to earlier Expedition models with V8 engines, the EcoBoost offers a more refined and quieter driving experience. While not a sports car, the Expedition MAX 3.5 EcoBoost provides confident and capable performance for its size and weight.
Equipment & Trim Levels
The 3.5 EcoBoost MAX variant typically came standard with a high level of equipment. Standard features often included leather upholstery, heated and ventilated front seats, a power-folding third-row seat, a premium sound system (often Bang & Olufsen), and a large touchscreen infotainment system with navigation. Optional extras included a panoramic sunroof, adaptive cruise control, and a rear-seat entertainment system. Trim levels above the base model often added features like upgraded leather, unique interior trim, and additional driver-assistance technologies. The Expedition MAX aimed to provide a luxurious and comfortable experience for both driver and passengers.
Chassis & Braking
The Expedition MAX utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension consists of an independent double wishbone setup with a transverse stabilizer bar, while the rear suspension employs an independent multi-link spring suspension, also with a stabilizer bar. This suspension 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 and control during emergency braking situations. The extended wheelbase of the MAX model contributes to a more stable and comfortable ride, particularly on rough roads.
Market Reception & Comparison
The 2021-2024 Ford Expedition IV MAX 3.5 EcoBoost received generally positive reviews from automotive critics. The engine was praised for its power and refinement, and the 10-speed transmission was lauded for its smooth operation. Fuel economy, while not exceptional for a vehicle of this size, was considered competitive within the full-size SUV segment. Compared to the standard Expedition and lower-trim models, the 3.5 EcoBoost MAX offered a significant performance upgrade. It also positioned itself as a strong competitor to the Chevrolet Tahoe/Suburban and GMC Yukon/Yukon XL, offering a compelling combination of features, capability, and comfort.
Legacy
The 3.5 EcoBoost V6 engine has proven to be a reliable and durable powertrain in the Expedition MAX. While some early EcoBoost engines experienced issues with timing chain tensioners, these problems were largely addressed in later model years. The 10-speed automatic transmission has also demonstrated good long-term reliability. On the used car market, the 2021-2024 Expedition MAX 3.5 EcoBoost commands a premium price compared to lower-trim models, reflecting its superior performance and features. This variant remains a popular choice for buyers seeking a spacious, capable, and comfortable full-size SUV.
