What must an AWD car have according to Technician A and B?

All-wheel drive (AWD) systems are designed to provide power to all four wheels of a vehicle, enhancing traction and stability under various driving conditions.

One essential feature of an AWD system is the presence of a differential between the two drive axles, which allows for the wheels on either axle to rotate at different speeds. This is particularly important during turns, where the wheels on the outside of the turn travel a greater distance than those on the inside. A differential in this context ensures smooth operation and prevents tire wear or drivetrain strain.

Additionally, AWD vehicles typically have a differential in each drive axle—front and rear—enabling the wheels on each axle to turn at different rates as needed. This setup contributes to the overall effectiveness of the AWD system, providing balanced performance and enhancing the vehicle’s ability to handle diverse driving conditions.

Therefore, having both a differential between the two drive axles and a differential in each drive axle is crucial for an AWD setup. This comprehensive system allows for optimal power distribution and handling, aligning with the correct choice of both characteristics being fundamental to the operation of an AWD vehicle.
