I dont understand what it does and how it works, what does it compare to, how is it?

It was a transmission invented by Leonardo Da Vinci. Yeah, it had been around for a while, but not until recently, we do not have a material that is reliable enuff to handle 100MPH of rotation.
Concept is simple, two pulley tights up with belt in between. By adjusting the size of the two pully, you get unlimited gear ratio.

CONTINUOUSLY VARIABLE TRANSMISSION.
This transaxle represents the start of a new generation of automatic transmissions. This is a continuously variable transaxle (CVT) that permits the engine to operate at its most efficient running speeds. There are no discrete gear shifts and no interruptions in the power flow during acceleration. Instead, optimum use is always made of the engine's potential to transmit its full torque to the wheels. Since this is a continuously variable transaxle, there is an infinite number of gear ratios, so that the optimum engine operating point can always be found. Like the engine, it is located transversely in the vehicle. The mechanical section of the automatic transaxle contains 2 pressure controlled variator assemblies, a high performance chain and a single planetary gear set. The variator assemblies function as pulleys. One is connected to the engine output through the converter. The other is connected to the driveline through the transaxle differential. The chain passes around the pulleys connecting the transaxle input and output. The axial distance on each pulley where the chain travels can be varied. As the axial distance on one pulley decreases (becomes narrow) the other pulley increases (becomes wider) creating the speed (gear) ratio between them. This ratio varies continuously. The chain length remains constant. The single planetary gear set is used to change the rotation of the pulley assemblies for forward or reverse driving ranges. A combined hydraulic and electronic control system (mechatronic) is used to control the transaxle function. The mechatronic is located inside the transaxle. The CVT uses a torque converter with a lock-up clutch.

The continuously variable transmission (CVT) is a transmission in which the ratio of the rotational speeds of two shafts, as the input shaft and output shaft of a vehicle or other machine, can be varied continuously within a given range, providing an infinite number of possible

It's alot like a 12 speed bicycle on how it works.Continuously Varible Transmission. 2 tapered shafts parallel to each other with a belt running from 1 to the other. 1st shaft output, 2nd drive. Small on output, big on drive=slow. Big on output, small on drive=fast. And the belt can go anywhere in between(no shifts).

basically, it doesn't "shift". it just keeps going
