Dont forget that (not only) modern cars and their performance depend a lot on tires.
True but most drivers drive their cars on normal roads and to be honest, I wouldn't buy an Aventador for track use. Futch is a different story, he has so many cars to choose from, I wouldn't compare to the standard sports car buyer.
Ive started on my 12C with standard P Zeros and it made the car look bad performance and traction wise. After 2500km i switched to Michelin Pilot Sport Cup 2 and boy what a difference. Driven the tire through 6 trackdays and 14000km and i was very happy with the overall feel. Now i switched to Pirelli Trofeo R (standard on 675LT) and they are even (not by much) better.
Well, the PZero is a very good road tire but not really made for serious track use. On the other hand, I wouldn't really want to drive a semi-slick on normal roads. Did that twice (Michelin Cup and Goodyear F1 Supercar G:2) and I wouldn't recommend it at all. Very nice if you live in a region with hot road surfaces and warm temperatures but if the road surface is below 25°C and if the outside temperature drops below 20°C, the semi slicks are even dangerous for normal road use. These tires need temperature and it is almost impossible to get them to the right temperature during normal road use, even at higher temperatures. No thanks.
So many journalists and also testdrives compare the feeling between a 12C on P Zero a 650S on P Zero Corsa and a 675LT on Trofeo R. And after extensive time in the 650S its mainly the tire where all the magic comes from.
I am pretty sure that McLaren also did some chassis/steering tweaking, not only tires.
