The Ford Explorer IV 4.0i V6 Sport Trac 4WD, produced between 2006 and 2010, represents a popular iteration of Ford’s well-regarded SUV. This variant occupied a middle-ground position within the fourth-generation Explorer (2006-2010) lineup, offering a blend of capability, comfort, and a more potent engine option compared to the base models. It was designed to appeal to buyers seeking a versatile vehicle suitable for both daily commuting and light off-road adventures. The Sport Trac designation denoted a specific trim level focused on a more rugged aesthetic and enhanced functionality. This model was primarily marketed in North America, capitalizing on the continued demand for mid-size SUVs with four-wheel drive.
Powertrain & Engine Architecture
The heart of the Explorer IV 4.0i Sport Trac is the 4.0-liter Cologne V6 engine. This engine, internally designated as the 4.0L OHV, is a naturally aspirated, 12-valve (two valves per cylinder) powerplant. It utilizes a cast iron block and aluminum cylinder heads. The engine employs a multi-port fuel injection system, delivering fuel directly to each intake port for improved combustion efficiency. The 4.0L V6 is known for its robust construction and relatively simple design, contributing to its longevity. Paired with this engine is a 5-speed automatic transmission, providing smooth shifts and convenient operation. This transmission was a common choice for Ford SUVs of this era, offering a balance between fuel efficiency and performance. The 4×4 system is a shift-on-the-fly system, allowing the driver to engage four-wheel drive when needed for improved traction.
Driving Characteristics
The 208 horsepower and 241 lb-ft of torque produced by the 4.0L V6, when channeled through the 5-speed automatic, provided adequate, though not exhilarating, performance. Acceleration from 0 to 60 mph typically took around 8-9 seconds. Compared to the higher-output 4.6L V8 option available on some Explorer trims, the 4.0L felt less powerful, particularly when fully loaded or towing. However, the automatic transmission offered a more relaxed driving experience than the available manual transmission. The gear ratios were tuned for everyday drivability, prioritizing smooth cruising and sufficient low-end torque for moderate off-road conditions. The Sport Trac trim’s suspension was slightly firmer than the base Explorer, offering improved handling and stability, but at the expense of some ride comfort.
Equipment & Trim Levels
The Sport Trac trim level generally included features such as alloy wheels, a color-keyed body cladding, and upgraded interior trim. Standard interior features typically included cloth upholstery, air conditioning, a CD player, and power windows and locks. Optional extras included leather upholstery, a sunroof, a premium sound system, and a navigation system. The Sport Trac also often featured a unique instrument cluster design and specific badging to differentiate it from other Explorer trims. The overall interior design was functional and durable, reflecting the Explorer’s intended use as a family vehicle.
Chassis & Braking
The Explorer IV 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 coil springs. This configuration offered a good balance between ride comfort and off-road capability. Braking duties were handled by disc brakes on all four wheels, providing adequate stopping power for the vehicle’s weight. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The Sport Trac trim often featured slightly heavier-duty suspension components to accommodate the increased demands of off-road driving.
Market Reception & Comparison
The Explorer IV 4.0i Sport Trac 4WD was generally well-received by critics and consumers alike. It was praised for its versatility, spacious interior, and comfortable ride. However, some reviewers noted that the 4.0L V6 engine felt underpowered compared to the V8 option. Fuel economy was also a common criticism, with the 4.0L V6 averaging around 15-20 mpg in real-world driving. Compared to the V8-powered Explorers, the 4.0L Sport Trac offered a more affordable entry point into the Explorer lineup, appealing to buyers who prioritized fuel efficiency and value over outright performance. Compared to competitors like the Chevrolet TrailBlazer and Jeep Grand Cherokee, the Explorer offered a more refined interior and a more comfortable ride.
Legacy
The 4.0L V6 engine and 5-speed automatic transmission combination found in the Explorer IV Sport Trac proved to be relatively reliable. While not without its potential issues (such as timing chain wear and oil leaks), the powertrain generally held up well over time with proper maintenance. Today, these Explorers can be found on the used car market at relatively affordable prices. They remain popular choices for buyers seeking a capable and versatile SUV for family transportation or light off-road adventures. The simplicity of the 4.0L V6 engine makes it relatively easy and inexpensive to repair, contributing to its continued appeal among DIY mechanics and budget-conscious buyers.
