Question

Quizplus · Accepted Answer

Technician A is correct because all-wheel drive (AWD) systems distribute power to all four wheels to improve traction. Technician B is also correct because many AWD vehicles can operate in a 2WD mode under normal driving conditions to improve fuel efficiency, automatically engaging all four wheels when additional traction is needed.
