As much as Ferrari HATES the Nurburgring, I am 100% SURE that the 488P would beat the Corvette ZR1 (standard low-wing model) and the non-Weissach 991 GT3 RS on that track with an identical driver under equal conditions. Although a magazine got 7:00 flat, I got 7:04 which is still very close. It would beat the Huracan Performante and GT2 RS if it had a big wing like those two cars.

GTB: ((20600m/(300km/h/((141m*(5.19/1.13))x0.3048m))x(1586kg/695hp)/1.13g)x0.0095x0.35 = 7:19
Pista: ((20600m/(300km/h/((146m*(4.93/1.15))x0.3048m))x(1542kg/712hp)/1.15g)x0.0095x0.375 = 7:04
"Only" 15 seconds apart? That's actually a HUGE difference, especially when the Pista IS NOT wearing a Lambo/Porsche-style WING!!!
Anyways, 992 hp is the GTB's maximum potential (not stock, of course), while 949 hp is the Pista's; unfortunately, the GTB might do better than the Pista if it weighed the same as the Pista.
