Continuously Variable Transmission.
This is a type of automatic transmission that essentially uses a cone and belt
instead of sets of gears to transmit power from the engine to the wheels. As a
result, there are no regular shifts, just a constant and unbroken (“stepless”)
progress as the engine maintains constant revs.
However, to ward off some buyer resistance to the monotonous drone of a
traditional CVT, some manufacturers engineer artificial ‘stepped ratios’ to
mimic a regular automatic’s characteristics. Hence the Honda Jazz
has a “seven-speed CVT”.
