The Lincoln Navigator IV L, specifically the facelifted version introduced in August 2021 and continuing through the 2024 model year, represents the fourth generation of Lincoln’s full-size luxury SUV. This variant, equipped with a 3.5-liter twin-turbocharged V6 engine producing 440 horsepower and paired with a 10-speed SelectShift automatic transmission, occupied the upper echelon of the Navigator lineup, offering a blend of power, luxury, and towing capability. It built upon the foundation of the Navigator IV platform, sharing its core structure with the Ford Expedition, but distinguished itself through unique styling, a more refined interior, and advanced technology features. The 2021 facelift brought updated exterior styling, enhanced interior materials, and improvements to the vehicle’s technology offerings, solidifying the Navigator’s position as a competitor to Cadillac Escalade, Jeep Grand Wagoneer, and other premium large SUVs.

Technical Specifications

Powertrain & Engine Architecture

At the heart of the 2021-2024 Lincoln Navigator IV L with the 440 hp configuration lies Ford’s 3.5-liter EcoBoost V6 engine. This engine, designated as part of the EcoBoost family, utilizes a twin-turbocharger setup to deliver substantial power and torque. The engine employs direct fuel injection combined with multi-port fuel injection, optimizing combustion efficiency and reducing emissions. The valvetrain features Twin Independent Variable Camshaft Timing (Ti-VCT), allowing for precise control of valve timing to maximize performance across the engine’s operating range. The 10-speed SelectShift automatic transmission is a crucial component, providing smooth and responsive gear changes. This transmission’s wide gear ratio spread contributes to both strong acceleration and improved fuel economy. The transmission is electronically controlled, adapting shift patterns based on driving conditions and driver input.

Driving Characteristics

The 440 horsepower and 691 lb-ft of torque produced by this powertrain configuration translate into impressive performance for a full-size SUV. Acceleration is brisk, with the Navigator capable of quick bursts of speed for merging onto highways or overtaking other vehicles. The 10-speed transmission helps keep the engine in its optimal power band, providing a smooth and controlled driving experience. Compared to lower-output Navigator trims, this variant offers a noticeable performance advantage. While the base engine provides adequate power, the 440 hp version delivers a more confident and engaging driving experience. The rear-wheel-drive configuration contributes to a balanced feel, although four-wheel drive is available as an option for enhanced traction in inclement weather. The Navigator’s substantial weight is noticeable, but the powerful engine mitigates this, providing ample power for towing and hauling.

Equipment & Trim Levels

The 440 hp Navigator typically came standard with a high level of equipment, reflecting its position as a premium trim. Standard features included leather upholstery, heated and ventilated front seats, a premium sound system, a large touchscreen infotainment system with navigation, and a suite of advanced driver-assistance systems such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras included massaging front seats, a rear-seat entertainment system, and upgraded interior trim materials. The Navigator IV L offered several distinct trim levels, with the 440 hp engine generally available on the higher-end Reserve and Black Label trims. These trims further enhanced the luxury experience with exclusive exterior styling cues and even more premium interior appointments.

Chassis & Braking

The Navigator IV L utilizes an independent coil spring suspension in the front and an independent multi-link spring suspension in the rear, providing a comfortable and controlled ride. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The front brakes measure 350.52 mm, while the rear brakes are slightly smaller at 335.28 mm. Anti-lock braking system (ABS) is standard, enhancing safety and control during emergency braking situations. The Navigator’s substantial weight necessitates a robust suspension and braking system to ensure confident handling and stopping performance.

Market Reception & Comparison

The 2021-2024 Lincoln Navigator IV L with the 440 hp engine received generally positive reviews from automotive critics. It was praised for its powerful engine, luxurious interior, and advanced technology features. Fuel economy, however, was a common criticism, as expected for a vehicle of this size and weight. Compared to other trims in the Navigator lineup, the 440 hp version offered a significant performance upgrade, justifying its higher price tag for buyers prioritizing power and acceleration. Against competitors like the Cadillac Escalade and Jeep Grand Wagoneer, the Navigator held its own, offering a compelling combination of luxury, performance, and value.

Legacy

The 3.5-liter EcoBoost V6 engine paired with the 10-speed automatic transmission has proven to be a reliable powertrain combination in the Navigator and other Ford/Lincoln vehicles. While long-term reliability data is still accumulating for the facelifted 2021-2024 models, the EcoBoost engine has generally demonstrated good durability. On the used car market, Navigators equipped with this powertrain configuration command a premium due to their enhanced performance and desirable features. The Navigator IV L, particularly in its higher trims, continues to be a sought-after luxury SUV, offering a spacious and comfortable interior, powerful engine, and a refined driving experience.
