The 2018 Ford Explorer represents a significant moment in the evolution of the iconic three-row SUV, blending refined on-road dynamics with capable off-road prowess thanks to its available four-wheel-drive system. This model year marked the continued dominance of the Explorer in the competitive mid-size SUV segment, offering families and adventure-seekers a versatile platform that did not compromise on comfort or technology. Understanding the specifics of the 2018 Ford Explorer 4 wheel drive setup is essential for anyone considering a used model or appreciating the engineering that went into this popular vehicle.
Available Powertrain and 4WD System
For the 2018 model year, the Ford Explorer offered a choice of engines, with the available four-wheel drive system designed to work seamlessly with the powertrain. The standard 3.5-liter EcoBoost V6, producing 365 horsepower, was most commonly paired with the intelligent all-wheel-drive system, although it was often marketed and functioned as a capable four-wheel-drive setup. This powertrain combination was mated to a six-speed automatic transmission, sending power to all four wheels through a multi-plate clutch system managed by the intelligent all-wheel-drive control module.
How the System Works
The intelligent all-wheel-drive system in the 2018 Explorer is designed to provide optimal traction and stability in various driving conditions, from wet pavement to light off-road terrain. Under normal driving conditions, the system primarily sends power to the front wheels to maximize fuel efficiency. However, sensors constantly monitor wheel slip, and when the system detects a loss of traction, it can instantly transfer power to the rear wheels.
Front-wheel-drive for efficiency: The system defaults to front-wheel drive during normal cruising to improve fuel economy.
Instant power transfer: When slippage is detected, the multi-plate clutch engages to send up to 100% of the available torque to the rear axle.
Driver-controlled mode: The system offers a driver-selectable mode that can be set to prioritize fuel efficiency, normal all-weather performance, or enhanced off-road capability.
Capabilities and On-Road Performance
One of the primary strengths of the 2018 Explorer with its four-wheel-drive system is its ability to handle diverse driving environments with confidence. On the highway, the Explorer provides a smooth, quiet, and planted ride, with the AWD system contributing to confident cornering and braking in various weather conditions. The system is not a performance-oriented setup like those found on sports cars, but it excels at maintaining composure during everyday driving scenarios, whether navigating a snowy driveway or merging onto a rainy interstate.
Off-Road Capacity and Limitations
While the 2018 Explorer is often categorized as a crossover, its available four-wheel-drive system grants it surprising capability for light off-road adventures. The high ground clearance, combined with the traction provided by the AWD system, allows the Explorer to tackle dirt roads, gravel paths, and muddy trails that would challenge a standard two-wheel-drive vehicle. It is crucial to understand, however, that this is not a hardcore off-road vehicle; it lacks features like a low-range transfer case, locking differentials, or advanced skid plates found on dedicated off-roaders.
Off-Road Features and Considerations
The Explorer's off-road capability is enhanced by several design elements that work in conjunction with the 4WD system. The suspension is tuned to handle uneven terrain, and the available all-terrain tires provide a balance of on-road comfort and off-road grip. For drivers planning more serious off-road excursions, aftermarket modifications such as a skid plate and all-terrain tire upgrades are often recommended to protect the undercarriage and improve traction in challenging conditions.
