The ID.3 does have glitchy software and many reviewers picked up on this, an update is due (or has very recently happened). The software will be fixed for the ID.4. Also positive about many new EV’s as well is that software/firmware updates now happen over the air waves automatically and you do not have to take the car into the dealership.
With regards mileage there are independent WLTP mileage figures which are the ones to look at. From what I have seen from online reviewers VW (and possibly other manufacturers) are overestimating by at least 10%, however, as EV’s are now in the 250-300+ mile range and the infrastructure of charging points is growing daily, I do not see this as a major issue – irritating, but not a deal breaker.
I prefer the ID.3 to the ID.4 – just a shame about the boot space. I don’t think VW have got the boot right in the ID.4 either – why cant they do level boot space – especially when the rear seats are folded as well and especially when Skoda can do it? I would expect more from a new EV platform.
