Four-wheel drive, 4WD, or 4x4 ("four by four") is a four-wheeled vehicle with a drivetrain that allows all four wheels to receive power from the engine simultaneously. In the United States, these cars are often, but not always, included in the broader sport utility vehicle  category. While many people associate the term with off-road vehicles, powering all four wheels provides better control on many surfaces, and is an important part of rally racing.
