Xpeng are probably right about range, but we are facing a major problem in the UK with the lack of rapid chargers when everyone decides to go on a driving holiday at the same time.
The sooner the Gov’t kicks Ecotricity out of motorway service stations the better, else those service stations will be bankrupt in 10 years as they can’t charge just one EV at a time as is the current average. The only alternative to the charging problem is Tesla superchargers at the moment.
Meanwhile there are a lot of rapid chargers springing up just off the motorways, e.g. J27 M6 8 new ultra rapids, but they’re awaiting connection by the DNO who just plod along at a snail’s pace in the UK. This is the reason that BP ultra rapids at Reading services on the M4 sit idle, it’s the same all over the country.
