Thinking about changing my Sport to a full size Range Rover. Problem is, I have seen two that I like, both 2021 Autobiography, one is P400e, other is a P525. I am not a leccy car lover, but the mileage will be pretty low (the Sport is 2014, bought new with just under 20000miles at time of writing fsh & looked after by Disco Mikey) so I thought that the P400e could be wafting about on leccy most of the time. I was wondering if they have any battery problems. Looking on line, people seem to be getting a lot lower miles than the projected around 30 & charging never reaching 100%. Also some complaints that when battery is depleted they seem to struggle a bit with the extra battery weight.
P525 was going to be first choice until I saw the P400e & started me thinking (often a bad thing). Really wanted HUD which my S63 has & think it's great. P400e has it but the P525 doesn't but its not a deal breaker. Are there any problems on the P525 that I should be aware of.
Advice welcome. Range Rover Sport: Mercedes S63 AMG Coupe: 992 Porsche Carrera 4S

I've been happy with my 2021 P400e. I can get around 25 miles of wafting on a trip with mine, but of course that depends on conditions and driving style.

Once the battery is depleted, I don't find that the performance in any way suffers. Mine will charge up to between 29 and 31 miles (I guess depending on conditions and whatever the onboard circuitry is deciding on any one day). I had problems with charging with the granny cable to start with, but those problems stopped when I bought a JLR branded charger.

I like mine, but then most of my trips are relatively short ones (up to 30 miles most days). 2021 P400e Autobiography
