In a combustion-engined car, which system mechanically transmits engine motion to the driven wheels?

Correct answer

Transmission system

The transmission system. Its components depend on vehicle design and may include a clutch, gearbox, shafts and differential. Cars do not all have the same gearbox or identical disengagement function. The cooling system controls temperature; it does not perform this mechanical transmission of motion.
