The cvt will auto down shift when you finally reduce the speed ahead of moving into corner and you simply travel it a tiny bit more durable.
It lags because it utilizes a start clutch to transfer ability in contrast to the current gen CVT which takes advantage of a torque converter. It was once a dilemma while in the 2nd gen Honda Town CVT that has a similar setup.
With a conventional torque converter, the transfer of electrical power is quick similar to in a standard automatic transmission. That's why Proton is going for Jatco CVT for its future design to address this issue. Jatco materials CVT for equally mitsubishi and Nissan
