Hi Muldoon, I have had 4 Jazz cars, all of them autos, 3 CVT and 1 I-shift.
I know the I-shift tends to be a Marmite thing, but in my opinion, I certainly would not have another one.
If you want the lazy style of motoring, then the CVT ticks all the boxes and I certainly don’t recognise the CVT as noisy.
Yes, the engine does rev a little more than the manual, but this is simply because the engine power band really starts to get going above circa 3k revs.
Whether you have Manual or Auto, if you want the power you need the revs.
At 70mph the engine speed is less with the CVT than the Manual and gives a very relaxed drive.
