The use of belts or pulleys instead of steel gears results in variable gear ratios dependent on engine speed or RPM. Nothing quite like the good old torque converter. Popular cars using CVTs include the Maruti Suzuki Baleno, Hyundai i20 and Honda City. As far as CVT vs DCT or automatic, CVT is still better; as a DCT transmission is endlessly complex, costly, weighs a lot, and has about the same losses as a CVT.

If you've driven a Toyota, Lexus or Honda hybrid, or any recent Nissan automatic, you'll be familiar with continuously-variable transmissions (CVT). Faced with the reluctance of privilege-car drivers to accept the CVT, but also faced with soaring emissions and fuel economy standards, the manufacturers have chosen to give us the DCT … No P mode! have come a long way. Maintenance and replacement of a torque converter is less expensive than a DCT or CVT. Simple design and working implies fewer complications and issues. Dual clutch transmissions (DCT) >> Continuously variable transmissions (CVT) >> ... Let’s say you want fuel economy, accelerating from 80 to 100 in a particular set of conditions. This is why a car like the GT TSI is still so popular.

For simple understanding, DCT (dual clutch transmission) has dual clutch fit in gearbox, one for odd gears while another for even. Chances of gearbox failures are really high. As a lubricant supplier, we want to understand the effects of fluid properties on CVT fuel economy (FE). While most automatic transmissions rely on either a torque converter or, if it’s a CVT, a system of pulleys, the dual-clutch transmission uses clutch plates, like a manual transmission. The DCT is not great and it does not really match well with the engine it is mated to.
