A 4x4 vehicle is a type of automobile designed to provide power to all four wheels simultaneously. This feature enhances traction and stability, making these vehicles ideal for off-road conditions, such as mud, snow, and rocky terrain. Common examples include SUVs and pick-up trucks that are equipped with a four-wheel-drive system. These vehicles often come with additional features like higher ground clearance and rugged tires, which further improve their off-road capabilities. Many 4x4 vehicles also have selectable drive modes, allowing drivers to switch between two-wheel drive and four-wheel drive based on the driving conditions.
