Four-wheel drive, All-wheel drive, AWD, 4WD, or 4x4 ("four by four") is a four-wheeled vehicle with a drivetrain that allows all fourwheels to receive torque from the engine simultaneously. While many people associate the term with off-road vehicles and Sport utility vehicles, powering all four wheels provides better control than normal road cars on many surfaces, and is an important part in the sport of rallying.
In-game characteristic Edit
In Maximum Tune series, 4WD cars generally have higher acceleration and top speed than RWD cars, which make them suitable for VS battle and time attack in Wangan area. However they are harder to control than RWD and has larger body, which make 4WD cars less suitable for time attack in most courses.
