The Ford Expedition, introduced in 1997 as a 1997 model, represented Ford’s entry into the burgeoning full-size SUV market, directly challenging the Chevrolet Tahoe and GMC Yukon. 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 the 1997 to 2003 model years. Within this generation, the 4.6L i V8 16V XLT 4WD (243 Hp) variant occupied a significant middle ground in the lineup, offering a balance of power, features, and price. It was positioned as a step up from the base models, providing more standard equipment and the added capability of four-wheel drive, while remaining more accessible than the higher-trim Eddie Bauer or Limited editions.

Powertrain & Engine Architecture
The heart of the Expedition XLT 4WD was the 4.6-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 signified Ford’s commitment to a robust and reliable engine design. The 4.6L engine utilized a single overhead camshaft (OHC) design with two valves per cylinder. Fuel delivery was managed by a multi-port fuel injection system, providing precise fuel metering for improved efficiency and performance. The engine produced 243 horsepower at 4750 rpm and 293 lb-ft of torque at 3500 rpm. The engine was mated to a four-speed automatic transmission, specifically the 4R70W. This transmission was chosen for its durability and ability to handle the substantial torque output of the V8 engine, as well as the added weight of a full-size SUV. The 4R70W featured electronic control for smoother shifting and improved fuel economy.
Driving Characteristics
The 4.6L V8 and 4R70W combination in the Expedition XLT 4WD delivered adequate, though not exhilarating, performance. Acceleration from 0-60 mph took around 10.5 seconds, which was competitive for the segment at the time, but noticeably slower than the available 5.4L V8 option. The automatic transmission’s gear ratios were tuned for towing and everyday driving, prioritizing smooth operation over outright speed. The transmission’s shift points were generally well-placed, but could feel somewhat hesitant during quick acceleration. Compared to the manual transmission options available in other Ford trucks, the automatic Expedition felt less responsive. However, the automatic provided a more relaxed driving experience, particularly in city traffic. The four-wheel-drive system offered enhanced traction in inclement weather and on unpaved surfaces, making it a capable all-weather vehicle.
Equipment & Trim Levels
The Expedition XLT 4WD trim level offered a good balance of features and affordability. Standard equipment typically included air conditioning, power windows and locks, a CD player, and cloth upholstery. The XLT also featured upgraded interior trim compared to the base models. Optional extras included leather upholstery, a power sunroof, upgraded sound systems, and rear-seat entertainment systems. The XLT trim was designed to appeal to families who wanted a comfortable and well-equipped SUV without the premium price tag of the higher-end trims.
Chassis & Braking
The Expedition utilized a body-on-frame construction, providing a robust and durable platform. The front suspension consisted of an independent torsion bar setup, while the rear suspension employed a solid axle with leaf springs. This configuration was chosen for its load-carrying capacity and durability. The XLT 4WD model featured ventilated disc brakes on the front wheels and disc brakes on the rear, providing adequate stopping power for the vehicle’s weight. Anti-lock brakes (ABS) were standard, enhancing safety during emergency braking situations. The hydraulic power steering provided a comfortable and responsive steering feel.
Market Reception & Comparison
The Ford Expedition was generally well-received by critics and consumers alike. It was praised for its spacious interior, comfortable ride, and strong towing capacity. The 4.6L V8 engine was considered adequate for most drivers, but some reviewers noted that it could feel underpowered when fully loaded or towing a heavy trailer. Compared to the Chevrolet Tahoe and GMC Yukon, the Expedition offered a more modern interior and a smoother ride. Fuel economy was typical for a full-size SUV of the era, averaging around 13-18 mpg in combined driving. Reliability was generally good, although some owners reported issues with the automatic transmission and the rear suspension.
Legacy
The first-generation Ford Expedition established itself as a major player in the full-size SUV market. The 4.6L Triton V8 engine, while not the most powerful option, proved to be a reliable and durable powerplant. Today, well-maintained examples of the Expedition XLT 4WD are still found on the used car market, often appealing to buyers seeking an affordable and capable SUV. While the 4.6L engine may not offer the performance of newer engines, its simplicity and proven design make it relatively easy and inexpensive to maintain. The Expedition’s spacious interior and strong towing capacity continue to make it a practical choice for families and those with active lifestyles.
