They used an old version of the Model S, the P100D, not the current Performance version which is available today. Not a like-for-like test. (And if you want to compare not-yet-available versions with a similar price, you really should be comparing to the trimotor Model S.)

And yeah, Model S is a more practical car than the Taycan yet still holds its own (in spite of Porsche's complex gearing system due to Tesla's electric powertrain advantage).

I'm glad a worthy challenger to the Model S has finally been produced. Tesla is having to up their game to stay ahead, which is good. Competition between these two will push electric cars far ahead of fossil cars even at the highest levels of performance.
