The Ford Expedition, introduced in 1997 as a 1997 model year vehicle, represented Ford’s entry into the burgeoning full-size SUV market. Replacing the Ford Bronco and the larger, truck-based Ford Explorer, the Expedition aimed to provide a more comfortable and spacious alternative for families and those needing substantial towing capacity. The first generation, designated the U173, spanned from 1997 to 2003. Within this generation, the 5.4 i V8 16V XLT variant, producing 232 horsepower, occupied a significant middle ground in the lineup, offering a balance of power, features, and price. It was positioned above the base models with the smaller 4.6L engine, but below the higher-trim levels that often included additional luxury features and sometimes, optional four-wheel drive.

Powertrain & Engine Architecture
The heart of the Expedition XLT was Ford’s 5.4-liter Triton V8 engine. This engine, part of Ford’s modular engine family, featured a cast-iron block with aluminum cylinder heads. The “Triton” name denoted the overhead camshaft (OHC) design, a departure from the pushrod engines previously common in Ford trucks and SUVs. The 5.4L engine utilized multi-port fuel injection, delivering fuel directly to each intake port for improved efficiency and power delivery. The engine produced 232 horsepower at 4250 rpm and 441 Nm (325 lb-ft) of torque at 3000 rpm. Paired with this engine was a four-speed automatic transmission, designed to provide smooth shifting and adequate gear ratios for both highway cruising and towing. This transmission was a crucial component in making the large SUV manageable for everyday driving.
Driving Characteristics
The 5.4L V8 and four-speed automatic combination in the Expedition XLT provided adequate, though not exhilarating, performance. Acceleration from 0-60 mph took around 9.5 seconds, which was competitive for a full-size SUV of the era. The automatic transmission was tuned for comfort and ease of use, prioritizing smooth shifts over aggressive downshifting. While the 4.6L engine felt strained when fully loaded or towing, the 5.4L offered a more relaxed driving experience in these situations. The gear ratios were optimized for highway cruising, but could feel somewhat tall when attempting quicker acceleration. Compared to the later addition of a five-speed automatic, the four-speed felt a bit dated, especially in terms of fuel economy.
Equipment & Trim Levels
The XLT trim level represented a step up from the base Expedition, offering a more comprehensive list of standard features. Typically, the XLT included features such as air conditioning, power windows and locks, cruise control, an upgraded audio system, and cloth upholstery. Optional extras included leather upholstery, a power sunroof, upgraded sound systems, and rear-seat entertainment systems. The XLT also often included features like alloy wheels and upgraded exterior trim. The interior design was functional and spacious, prioritizing practicality over luxury, though it was considered comfortable for its time.
Chassis & Braking
The first-generation Expedition utilized a body-on-frame construction, providing a robust and durable platform. The front suspension employed torsion bars, while the rear suspension utilized a solid axle with leaf springs. This setup was typical for full-size trucks and SUVs of the period, prioritizing load-carrying capacity and towing ability. Braking duties were handled by ventilated disc brakes at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, enhancing safety and control during emergency braking situations. The steering was hydraulic power-assisted, providing relatively easy maneuverability despite the vehicle’s size.
Market Reception & Comparison
The Ford Expedition was generally well-received by critics and consumers alike. It offered a significant improvement in interior space and comfort compared to the Bronco and Explorer, while still providing the towing capacity and ruggedness expected of a full-size SUV. The 5.4L V8 engine was praised for its smooth operation and adequate power, although some reviewers noted that fuel economy was a concern. Compared to the base 4.6L engine, the 5.4L offered a noticeable performance advantage, making it a popular choice for those who frequently towed or carried heavy loads. The Expedition competed directly with the Chevrolet Tahoe and GMC Yukon, and generally held its own in terms of features, performance, and price.
Legacy
The first-generation Ford Expedition established a strong foundation for the model, and the 5.4L Triton V8 proved to be a relatively reliable powertrain when properly maintained. While the engine was known to have some potential issues with spark plug breakage and timing chain tensioner failure, these were often addressed with updated parts and regular maintenance. Today, well-maintained examples of the Expedition XLT with the 5.4L engine can still be found on the used car market, offering a relatively affordable and capable full-size SUV. Its robust construction and spacious interior continue to appeal to those seeking a practical and versatile vehicle.
