Infinitely variable transmission meaning

Infinitely variable transmission definition

(IVT or CVT) Most transmissions , whether manual or automatic have a fixed number of forward gears (from 2 to 10 or more). Belt driven vehicles (like snowmobiles) have an infinite number of positions of engagement. The infinitely variable transmission is sensitive to the changes in the throttle position and adjusts the gear ratio accordingly. In this way, the most efficient gear ratio is selected thus improving fuel economy . Also called "continuously variable transmission."
