This i4 comes with the adaptive ride option, combined with 18's I think the ride is incredibly smooth. My old 435i was fine on the motorway but to firm on rough B and A roads. This is near perfect if I'm honest for me and when you pop it in sport it firms up nicely.Its not so much the smoothness of the ride, but the firmness that seems to knacker my back. Thats how I've ended up with a pair of Jags, due to lack of any other viable options, and not my first choice.
Often my XJ isn't that smooth, as there aren't many points in time that all 4 wheels are round, but I have no issues doing distances in that, either driving or as a passenger. The seat in her XE is getting tired - base spec car so shitty seats, and its now 150k and I'm guessing the previous owner made me look skinny - but again no issues doing fair distances in that (although never done more than 200 miles in one journey in it).
The ride of yours is more curiosity than anything else. Its unlikely I'm going to be buying a milk float any time soon. My limited mileage makes it uneconomical (and our EV scheme is currently a bit wank on pricing), and her mileage is creeping into the territory of having to stop and charge during the day, which isn't ever going to happen. Additionally, she knows all too well the pitfalls and related costs of owning an EV.

- The N55 power plant decided to split a plastic pipe that ran from the expansion tank to the rad. No engine running issues, but it took 6L of coolant to fill her back up again
