4-1. What is CVT ? The CVT provides smooth and stepless ratio changes.Engine RevolutionsATCVT0Time1818

4-2. Special Features of CVTStepless shifting of gear ratios for enhanced drivingpleasure and fuel efficiency1919

4-3. CVT Efficiency (Fuel) (1)Engine Torque (Nm) CVT changes gears smoothly so cars consume fuel efficiently.Optimum area offuel efficiency ratioCVTATEngine Revolutions (rpm)2020

4-3. CVT Efficiency (Fuel) (2) AT can only use set gear ratios so large changes in enginerevolutions means it is difficult to use fuel efficiently while driving.Limited to setgear ratios1 speed2 speed3 speed4 speed5 speedCar SpeedCVTLowestEngine RevolutionsEngine Revolutions5ATThis area can be usedHighestCar SpeedOptimum area for efficient fuel consumption2121
