I am curious -- how are they determining remaining range? if it is from the battery SOC indicator, that is notoriously inaccurate (on the Tesla anyway). Unless they were driving it at conditions close to the EPA test, the stated range is simply not meaningful. And it is very difficult, expect on a closed course with steady speed, to drive in a way that matches the EPA test so that the range comparison is meaningful. If they were using the Tesla energy app, well, that is a different story. But even so, how do they know that the Tesla and Porsche range indicators or energy apps (if the Taycan has something like it) are anywhere near equivalent? If one is more optimistic than the other, the comparison is meaningless.
I have been convinced by reading zillions of posts on this and watching many videos that the better way to determine what you can get from the car is to do a test where you measure the energy you can extract in driving down form 100% to near zero, which is the method that Bjorn Nyland uses. Then the range is a function of your speed etc. You can use the EPA value to estimate the range, but first you have to know what energy you can actually obtain and use from the battery.
