A CVT doesn’t have gears at all. Instead, it uses a cone shape with a band around that and another axle. The band can be moved up and down the cone to vary its length and therefore the gear ratio. Theoretically it offers infinitely variable ratios between its upper and lower limit, meaning it can be perfectly optimised for fuel efficiency or performance at any given time. This is particularly helpful for hybrid cars, which can use a CVT to balance the workload between the petrol engine and electric motor.
