Why are 4×4 vehicles (Such as the Jeep Wrangler) Limited in speed (80kph as per the owner manual) in 4WD mode, whereas a full time All-Wheel Drive vehicle doesn’t have any such limit (within the li…
4WD locks the front and rear axles together mechanically. It's either on or off. AWD uses an differential to change how much each axle is used.
The Short Answer
4WD locks the front and rear axles together mechanically. It's either on or off. AWD uses an differential to change how much each axle is used. Sometimes this differential is adjustable by the computer.
