If you look at the Nurburgring lap time list, for example (https://fastestlaps.com/tracks/nordschleife), you will notice 2 modified lap times, one even being the #1 fastest lap.
There are few modified lap times in the laptime charts, they are clearly marked as "modified" and can even be removed from the list if you uncheck Filters > Modified checkbox.
This particular Tesla wasn't even close to the extremes in car modding that we have seen in BM Hot Version etc. This is more like Manthey Racing Porsche GT2. The engine (pardon, the motors) is stock, power output is stock.
