I haven't seen any difference in mileage. My JDM Alto with CVT gives lesser mileage than VXL but again my JDM Alto is 5-6 years old and has clocked 65k km.
When i bought it new it was 5200km driven and mileage i used to get was 23-25
Now mileage i get is 21-22
VXL gives me mileage 23-24
So i would call that negligible difference in mileage in both cars.
Now coming to the feel and driving experience of both CVT is a please while AGS feels like an extremely inexperienced driver is sitting inside the engine bay and ghenta lga k clutch dba k gear change kar rha hai.
I would seriously compare that to a khota gaari jis mein the donkey gets tired and you hit him tou aik dam se gear change k sath jhatka and speed pakar li next gear mein.
Does one get used to it ?
Yes definitely you get used to it and feels like normal because you learn the pedal feel k kitni speed pe kitna pedal ko chorna hai tou foran gear change ho gaye ga tou uske baad normal hi lagta hai . You dont feel k buri transmission hai
My JDM went out of town for a week and i got used to AGS until it came back and now i have both some time driving one and some time the other and it feels like hell driving the AGS.
If you dont have a second car thats even an simple auto then theak hai you wont feel anything
But if you have a second car that has a auto trans or CVT then uske sath AGS chalana bas se bahar hai
