The clutches operate independently - one controls the odd-numbered gears, the other the even gears. As a result, in normal driving conditions, especially when the driver accelerates hard, there is a perceptible disconnect between the soaring engine rev and the actual rate of acceleration.Ĭars: Toyota, Honda, and Nissan use CVTs in the City and new Elevate SUV, Magnite, and the non-hybrid Innova Hycross.ĭCT: There are two clutch packs controlled by a sophisticated network of electronics and hydraulics. They move in tandem with engine revs, with the two cones moving independent of each other, and thereby imparting the mechanism infinite gear ratios (depending on the length of the drive belt).Ī CVT is extremely fuel-efficient and smooth compared to conventional automatics, but involves the so-called ‘rubber band effect’ - a lag between when throttle input is received and when it kicks in.
One pulley is connected to the engine, the other to the wheel shaft.
CVT: This is essentially a single-speed auto gearbox with two cone shaped pulleys connected by a drive belt.
