Continuously variable transmissions (CVT) offer an infinite number of gear ratios that allow the engine to operate near peak efficiency throughout a wide range of vehicle speeds which improves fuel efficiency. The sales of vehicles with CVTs began slowly and have climbed to 13.8% of car and 5.3% of light truck market share. With CVT making up a relatively small percentage of all transmissions, changes to model offerings with CVTs can have a pronounced effect on the year to year percentages shown in the graphs below.
