@Rhodgie The RR has a much more sophisticated suspension set up than your average BEV (double-wishbone with air springs) It’s designed as a luxury (and very expensive) vehicle to provide a smooth ride. Range Rover weighs in at about 2.3 tonnes with biggest BEV than I can think of being the Kia EV9 weighing in at 2.6 tonnes on standard multilink suspension.
Having said that, I’d agree with other posters that wheel and tyre size also has a significant impact on ride comfort.
