The CVT’s ability to maintain optimal engine rpm and vehicle momentum through its shiftless operation creates a more efficient system than traditional automatic and manual transmissions. One does not feel the car shift gears or a sudden lurch upon acceleration because there are no gears to begin with. Fuel efficiency and lower emissions are the top benefits of continuously variable transmissions. Instead, they rely on two cone-shaped pulleys to transfer power from the engine, through the transmission, and to the drive wheels. Both transmissions can be automatic since the driver does not need to shift the gears. Continuously Variable Transmission (CVT) Although a CVT operates in a similar fashion as a traditional automatic transmission, they are quite different in their construction. If you consider their names, it would appear that they are similar. As you may have already guessed, its predecessor, the CVT, means Continuously Variable Transmission. When you step on to accelerator, the car revs really high, this is normal and then settles down after the momentum has been built. eCVT stands for Electronic Continuously Variable Transmission. Of course, there are just two pedals (Brakes and accelerator) in the footwell, which might be disconcerting for people who are used to having three pedals (the clutch included). When you engage the 'Low' function, the car revs higher and generates more torque which might be required for pulling load or climbing a slope or getting out of a stuck situation. P-R-N-D-L (Parked-Reverse-Neutral-Drive-Low) which are self-explanatory except for the 'Low' which means low ratio. While the car gathers momentum and accelerates, the pulleys keep varying their diameters and lower the engine speed (RPMs) for relaxed cruising or climbing up the revs for quick overtaking.Įvery car with a CVT will have these markings on the gearknob. When the Input Pulley is becomes smaller and the output pulley becomes larger translates into a lower ratio (which is the number of times the shaft spins for every revolution of the engine, hence a ratio).
