RC:

I still wonder how McLaren does it from 200-300 kph...insane acceleration. There are certain rules in engine development, like thermodynamics/thermomanagement and emissions. Unless McLaren found the holy grail of engine technology but I doubt it. In the speed range 200-300 kph, the weight isn't really important, so...

I wonder about emissions output in the 200-300 kph speed range. I kind of have a feeling that it doesn't look good (even compared to the sportscar competition).

Weight seems to be a relevant aspect indeed: a friend (engineer) calculated that the 570s gains about 1.5s (!) between 200 and 300kph on the 991.2 turbo s due to the car's lower weight Smiley
