Automatic variator
* Variable Ratio (CVR): Uses a belt or chain running between two bevel pulleys. The pulleys have variable diameters, allowing the gear ratio to vary smoothly without steps.
* No conventional gears: Unlike automatic transmissions with gears, CVTs do not shift between fixed ratios.
*High Fuel Economy: By eliminating stepped gear shifting, CVTs can maintain the optimal gear ratio for a variety of driving conditions, reducing fuel consumption.
* Stepless acceleration: Smoothly changing gear ratios provide stepless acceleration without jolts or delays.
*Commonly used in fuel-efficient cars: CVTs are often found in small cars and hybrid vehicles due to their light weight and fuel economy.
Automatic transmission
*Fixed Ratios: Uses gears to create fixed ratios that shift electronically or hydraulically.
*Multi-speed: Has multiple gears (usually 4 to 10) with different gear ratios.
* Shifting: Automatic transmissions shift between gears to optimize performance and fuel economy.
* Sportier driving character: Fixed gears allow for more manual control over gear changes, which may be preferred by some drivers.
*Used in a Wide Range of Vehicles: Automatic transmissions are used in a variety of vehicles, from small cars to trucks and SUVs.
