What system transfers the power of the engine to the wheels?

The drive system is responsible for transferring the engine's power to the wheels, enabling the vehicle to move. This system includes various components such as the transmission, driveshaft, differentials, and axles, all of which work together to ensure that the torque generated by the engine is effectively delivered to the wheels. The drive system is crucial for the vehicle's performance and handling, allowing it to accelerate, steer, and maintain speed.

The suspension system, while important for supporting the vehicle's weight and ensuring a smooth ride, does not play a role in transferring engine power to the wheels. The braking system is designed to slow down or stop the vehicle, making it critical for safety but not for power transfer. The fuel system is responsible for delivering the fuel to the engine to generate power, but it does not concern itself with the actual transfer of that power to the wheels. This distinction establishes the drive system as the correct choice for the question.
