Unless the HRV is different, I'm finding my Jazz to be quieter on the motorway than my previous 9G Civic.
I cannot hear the engine kicking in and out or running on motorways. The only indication I have is the 'instant MPG' bar flicking between under 70 and at 140.
I am not sure why people who dislike the CVT 'MOOO' buy any car fitted with such.
Personally I don't mind it. I have owned a MkII jazz. and SWMBO has a MKIII currently. Neither of us are 'offended' by it. The only thing she really does not like is the long pause between hitting the throttle, and the car actually gathering up it's skirts when exiting a side road. It can cause a few scary moments sometimes.
My Karoq 1.5 DSG is pretty loud when given full 'beans' about the same as the CVT, but at least it gets up and goes when so instructed!.
The one thing about the Karoq that I will be glad to see the back of, when I get my HR-V of is the delay similar to CVT on takeoff, which is a mixture of turbo 'wind-up' and DSG 'lag'.
I was most impressed on the Crosstar drive, with the way it leapt off the mark under E power. INSTANT torque & GO! LUVLY!!
