A Continuously Variable Transmission has no gear ratios formed by fixed gears, such as a manual shift lever or automatic transmissions. Instead, a CVT transmission provides the vehicle's engine to run through the most efficient RPMs in a succession of vehicle speeds.
The most obvious use for a CVT automatic transmissions is at the moment you are seeking to ensure maximum fuel efficiency. However, this is too simple an interpretation for a system that implies a bit of complexity.
