The availability of four-wheel drive (4WD) in the Toyota Highlander is a significant factor for prospective buyers. It refers to a drivetrain system that can deliver power to all four wheels of the vehicle simultaneously. This contrasts with two-wheel drive (2WD) systems that only power either the front or rear wheels. When engaged, 4WD enhances traction and control, particularly on slippery surfaces or challenging terrain.
The inclusion of a 4WD system offers several advantages. It improves vehicle stability in adverse weather conditions such as snow, ice, and rain. It also allows for enhanced performance on unpaved roads or when navigating inclines. Historically, 4WD systems were primarily found on trucks and SUVs designed for off-road use. However, their integration into vehicles like the Highlander provides an added layer of safety and capability for everyday driving, especially in regions with variable weather patterns or uneven road surfaces.
