Being very skeptical about the above results, I ran a 4-lap Time trial test in Sainte-Croix Circuit B, with default setup, standard weight and power, and Racing Soft tyres.
My results:
Lamborghini Aventador LP 750 SV (2015): 2:15,389
Lamborghini Aventador LP 700-4 (2011): 2:17,329
Porsche Taycan (2019): 2:19,422
One could argue that, because Porsche is electric, I didn't manage to show it's full potetntial. Maybe, but 4 secs is a very big gap. I can't imagine how Taycan could be faster than Lambo SV.
