Part: Gearbox
Operation: How CVT (Continuously Variable Transmission) Works

The CVT gearbox (continuously variable gearbox) does not use gears but moving pulleys transmitted by a belt; one is connected to the drive shaft, the other to the drive wheels. The two elements are connected via hydraulic couplings, and via the belt the ratios can vary continuously on the basis of the engine revolutions. So the CVT gearbox manages to make the engine always work at the point of maximum efficiency, with low consumption and high comfort, and also an exceptional engine performance. However, they have a huge flaw, which makes them sound like a scooter gearbox, and customers don't like that noise that comes from the gearbox; therefore manufacturers make gearboxes that simulate ratios, modulating the distance of the pulley components, so as to pretend that there are actually ratios, as in a normal gearbox. The brands that use this type of gearbox are mostly Japanese: Subaru, Nissan, Honda, Mitsubishi, but also Renault. They are excellent in terms of cost, speed and comfort, but unfortunately there is very little regarding the enjoyment of the driver.
