Here's an article about the Taycan Turbo: https://www.automobilemag.com/news/2020-porsche-taycan-turbo-ev-electric-ride-review-photos/
If it is accurate then there are a couple of troubling points in it.
1) It says the car can drive along quite happily at 162 mph. Does that mean that is the top speed? If so that's pretty slow for the 'turbo' version.
2) It says it can do 10 0-60 mph sprints with no loss of performance. That is also disappointing. It should be able to do an unlimited number of them. If it can only do 10, then what does that say about track performance after 10 or 15 minutes of constant full throttle acceleration?
First of all the Taycan is meant to be a 4 door coupe not as such a sports car, therefore track capabilities are never going to be on the top of the priority list.
With that in mind how often will you actually need a top speed above 162 mph? Or to do more than 10 0-60 mph runs?
It might be true that the ICE powered equivalent (Panamera) might be able to do these things better, but ICE has been used in Porsche vehicles since the very beginning where the Taycan is the first Porsche EV, so it must be clear that the ICE will be far ahead in some aspects for quite a while until EV technology matures and Porsche gets to grips with it.
I think we need to wait at least a decade before we are going to see an EV road car which is actually useful and competitive on the track, a speciality EV for track use might be possible sooner, but the compromises needed might make it unbearable as a daily driver.
I personally think the Taycan promises to be a very impressive attempt at a first EV for Porsche, and I wouldn't mind owning one.
That being said I would not be tempted to trade my 718 for one, and given a choice between buying a 992 and a Taycan I would definitely not choose a Taycan, but as a third car alongside a 718 and a 992 I would love to have a Taycan
