Yes I agree with
@GeorgeG driver modes and Tyre profile may well make a difference to road noise, I also noticed a vast reduction in noise when I added Michelin eco tyres to my previous v-class.
We are a one car family so I don’t really have a comparison but the Horizon ride quality is superb and much quieter than our old V-280, it’s also much better balanced and by comparison has virtually zero body roll.
My drive back after collecting it was just over 4 hours and when I arrived I stopped, let the family in and we went out for a pootle around to grab a pub supper. I didn’t want to get out of it even at the pub.
I understood that it is fitted with active suspension, having not read any deeper into this I assumed that it may well be adjusted through driver modes, comfort hardly aligns with anything other than ride quality. To be honest the only noticeable difference I have witnessed between these modes seems to be the throttle response, it’s quite woolly in comfort and eco mode and tends to lag quite a lot, in sport and manual its a lot more responsive and feels more connected to the wheels, in sport it revvs much higher before selecting another gear..
Only had it a week and still exploring, but to be honest I have nothing to complain about. I think it’s fantastic.
