Re: Long range forecast. I watched an interesting video on Carwow youtube channel where they took 6 fully-charged EVs and drove them up the A1 until they ground to a halt. They were driving at motorway speeds and with lights on for part of the journey. The cars achieved between about 72% and 90% of their claimed range. However, if you combine the idea of rapid charging only up to 80% capacity, and that most suppliers will consider a battery to be healthy until capacity has fallen to 70%, then for practical purposes after a few years of ownership you may have a practicable range of about half the official value. Regardless of what the National Grid can supply, it is the local distribution network that will not be able to cope with a mass roll-out of battery vehicles. The cables buried in the street are just not large enough to supply enough current for every house to charge an EV, even on a relatively slow over-night charge.

According to an article on this website, manufacturers have been overly pessimistic about the longevity of batteries:

"Electric cars lose just one per cent of their battery capacity per year due to degradation, new research claims."

To look after the battery, it's best not to charge them beyond 90% regularly, but most people don't drive 200 miles per day, so that's not an issue. I'd also be surprised if the average Porsche Taycan purchaser kept the car for over eight years, driving on average in excess of 12,500 miles per year. In which case they can be sure that they'll keep at least 70% of the original range.

If they do, then it's probably not the right choice for them, but I think more people are put off electric cars by this worry than need to be.

I'd also be interested to see how the cost of replacing the battery in a Taycan compares to the servicing and fuel costs of a Panamera over the eight years...

re: "Every Which way" I suspect one of the problems facing users of Which reports is that they tend to regard the word of Which as gospel and look no further. When buying any product, let alone something as expensive as a car, I never rely on a single source of information (not even HJ!). Always read as many tests and reviews as you can then form your own judgement. When I first bought a car we had weekly copies of Motor and Autocar and that was it. With today's global cars the Internet brings a vast amount of information from both the UK and around the world - and highlights the danger of relying on one source when making an expensive buying decision.

Especially when many journalists and media outlets (certainly not accusing HJ and this site of doing so, quite the opposite in fact) seemingly copy one another's reports/reviews and change a few words here and there to avoid copyright claims.

My dad used to have Which and I read so much utter tripe in there I ignored it. I have since heard other people quoting their findings too so nothings changed. I think the concern with electric cars will be the used market years from now when the car itself may be fine (assuming all the sensors and radars have not failed and won't pass the MOT) but the battery will be nearing end of its natural life. The cost of a replacement battery will be more than the residual value of the car.

I used to find (over 10 years ago now) that Which was reasonably reliable and trustworthy/useful when looking into buying goods and services. Not any more - IMHO, they now seem to employ far less technically-capable people in the fields in which they are writing about and also appear to be going down the 'activist' route as well.

I would say there are nowadays LESS, not more good quality and trustworthy review sites for most products, cars included.

Battery life is an important factor. looking out of my office window at the work car park, more than 50 % of cars are more than ten years old. Many people would/could only spend a few thousand on a car, and working and living in a rural area means public transport is non existent.
