The Ford Excursion 7.3L Turbo Diesel with four-wheel drive and an automatic transmission, produced from 2001 to 2005, represents Ford’s entry into the full-size SUV segment, aiming to provide substantial towing capacity and interior space. Built on a heavily modified Ford Super Duty chassis, the Excursion was the largest SUV offered by an American manufacturer during its production run. This particular variant, equipped with the 7.3-liter Power Stroke diesel engine and a four-speed automatic transmission, occupied a significant position within the Excursion lineup, appealing to buyers needing robust performance for work or recreational activities. It was positioned as a premium offering compared to gasoline-powered Excursions, but below the later 6.0L Power Stroke models.

Powertrain & Engine Architecture
The heart of the Excursion 7.3L is the Ford Power Stroke diesel engine, specifically the 7.3-liter OHV (Overhead Valve) V8. Designated with engine codes like E4OD, this engine is renowned for its durability and relatively simple design compared to later Power Stroke iterations. The 7.3L utilizes a HEUI (Hydraulically Actuated Electronic Unit Injector) fuel injection system, which relies on high-pressure engine oil to atomize the fuel for efficient combustion. A variable geometry turbocharger with an intercooler further enhances performance by increasing air intake and reducing intake air temperature. The four-speed 4R100 automatic transmission was specifically reinforced to handle the substantial torque output of the 7.3L diesel. This transmission features a torque converter designed for heavy-duty applications and robust internal components.
Driving Characteristics
The Excursion 7.3L Automatic delivers a driving experience characterized by substantial torque and a comfortable ride, albeit with the inherent handling challenges of a large SUV. The 4R100 transmission provides smooth shifts, but isn’t particularly quick or sporty. Acceleration is adequate for its size, but the Excursion’s considerable weight (approximately 7,930 lbs) limits its responsiveness. The gear ratios are optimized for towing and hauling, prioritizing low-end grunt over outright speed. Compared to the manual transmission versions, the automatic offers greater convenience, especially in stop-and-go traffic, but sacrifices some control and fuel efficiency. The 7.3L diesel provides a broad torque curve, making it well-suited for navigating challenging terrain or pulling heavy loads.
Equipment & Trim Levels
The Excursion 7.3L was available in several trim levels, including XLT, Limited, and Eddie Bauer. The XLT served as the base model, offering standard features like air conditioning, power windows and locks, and a basic audio system. The Limited trim added features such as leather upholstery, heated front seats, and upgraded audio. The Eddie Bauer trim, the most luxurious option, included unique exterior styling cues, premium leather interiors, and additional convenience features. Common options included a DVD entertainment system, sunroof, and upgraded towing packages. Interior upholstery typically consisted of cloth or leather, with dashboard configurations varying depending on the trim level.
Chassis & Braking
The Excursion’s chassis is based on the Ford Super Duty truck platform, featuring a robust frame and heavy-duty suspension components. Both front and rear suspension utilize leaf springs, designed to handle substantial loads. The front suspension incorporates stabilizer bars to reduce body roll. Braking duties are handled by ventilated disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) for enhanced safety. Due to its weight, the Excursion requires a longer stopping distance compared to lighter SUVs. The steering system employs a hydraulic power steering unit for ease of maneuverability, although it can feel somewhat vague on the highway.
Market Reception & Comparison
The Ford Excursion received mixed reviews upon its release. Critics praised its spacious interior, impressive towing capacity, and powerful diesel engine. However, it was also criticized for its large size, poor fuel economy, and cumbersome handling. Compared to other full-size SUVs of the time, such as the Chevrolet Suburban and GMC Yukon XL, the Excursion offered more interior space and a higher towing capacity, but at the expense of fuel efficiency and maneuverability. The 7.3L diesel engine was generally well-regarded for its reliability and longevity, but maintenance costs could be higher than those of gasoline engines. Fuel economy typically ranged from 12-15 mpg in combined driving.
Legacy
The Ford Excursion 7.3L Turbo Diesel has developed a strong following among enthusiasts and those requiring a heavy-duty SUV. The 7.3L Power Stroke engine is known for its durability and relative simplicity, making it a popular choice for modifications and upgrades. While fuel economy remains a concern, the Excursion’s robust construction and ample space continue to appeal to buyers in the used car market. Properly maintained examples command a premium price, reflecting their reputation for reliability and capability. The Excursion represents a unique chapter in Ford’s SUV history, offering a combination of size, power, and durability that remains unmatched by many modern vehicles.
