The CVT is the major let down in the car. Other than that should be all good.

u must test drive if u have the chance.

the cvt in potong insaplah is miles ahead comparedto pravia.

1. noisy . so damn noisy at low speed.
2. at high speed, when change gear, noacceleration feeling, just number is changing and engine roar like lorry.

insaplah is quiet, and have the manual like feeling in manual mode( not entirely manual, but, i say 40 % feeling) when u downshift, it lures and goes faster and faster. when upshift, it will have the upshift feeling, like, hey, u decided not to strain the engine, thanks pal.

but pravia, hmm....no feeling in 3456 gear. only 1,2 gear has feeling.

First up I'd like to clarify that there are no gears in a CVT.

The gears are a set of virtual ratios controlled by the ECU or TCU.

It's nothing a reprogram can't fix if the gearbox can take the torque but I guess Punch/Proton decided to program it in a conservative manner.

i guess jatco is better than punch.

the cvt in nissan slyphy is also very good, very responsive.

All manufacturers will be conservative with TCU programming since warrantying a gearbox is nuts and plus with 10 years powertrain warranty some manufacturers are offers, it becomes an issue of cost.

Even Mitsubishi/Getrag, my GB shifts like a grandmother in normal mode. Which ironically destroys the clutch plates faster lol.

The CVT in inspira used torque based converter. The one in preve used wet clutch CVT.

A wet clutch should always transfer power better than a torque converter but at the expense of noise.

My Getrag has heaps of clutch noise.
