CVT
*Uses a continuously variable transmission (CVT) system that smoothly changes the gear ratio between the input and output shaft.
* Typically consists of two tapered pulleys connected by a metal belt or chain.
* The gear ratio is changed by shifting the pulley cones and adjusting the belt radius.
* Provides smooth acceleration and no jerky gear changes.
Automatic transmission (AT)
*Uses a mechanical or electro-hydraulic system to change gears.
* Usually has several fixed gears, such as five or eight.
* Gear changes occur at certain engine speeds and vehicle speeds.
* Provides sharper gear changes that can be felt by the driver.
