Question

Quizplus · Accepted Answer

Both statements are correct. All-wheel drive vehicles typically use a differential at both the front and rear axles to allow for differences in wheel speed between the front and rear. Some four-wheel drive systems also incorporate an interaxle differential (also known as a center differential) to allow for differences in wheel speed between the front and rear axles, enhancing drivability on various surfaces.
