The CVT’s belt-driven design offers approximately 88% efficiency, which is lower than that of a manual transmission, but this can be offset by lower production cost and by enabling the engine to run at its most efficient speed for a range of output speeds. Cruising in automatic mode is comfortable though.
Also known as semi-automatic transmission (SAT) or paddle-shift gearboxes, a semi-automatic transmission is a type of automatic transmission that it involves the driver making gear changes similar to a manual transmission. There are seven clutches, but there’s an eighth for the electronic differential. Solid service. It connects to the Electronic Control Unit of the engine and allows for precise control of the vehicle.
