Beyond fixed gears: how a transmission achieves infinite ratios

Technology · Published 7 October 2026 Swipe more like this →

In short: Most drivers are used to the distinct shifts of a traditional gearbox, but a Continuously Variable Transmission operates on a different principle. This video explores the mechanics of pulley-based systems and how they function without individual gears.

Unlike conventional transmissions that rely on a set number of discrete gears, a CVT utilizes a pulley-based design. This mechanism allows for an infinite range of possible gear ratios, providing a seamless transition between speeds.
