Actually, "four-wheel drive," "4-wheel drive," and "4x4 drive" all refer to the same thing: a drivetrain system that powers all four wheels of a vehicle simultaneously.
The difference in notation is mostly just a matter of style and preference. "Four-wheel drive" and "4-wheel drive" are both commonly used in the United States and other English-speaking countries, while "4x4" is often used in other parts of the world, particularly in Europe.
Regardless of the notation, the purpose of a four-wheel drive system is to provide increased traction and stability on challenging terrain or in adverse weather conditions, such as snow, mud, or sand. By powering all four wheels of a vehicle, it helps to distribute the engine's power more evenly and improve grip and control.
