What’s been done to improve efficiency and emissions?

Compared to the 599, fuel consumption has been reduced by 30% to give a combined average of 19mpg. This is achieved using Ferrari's optional HELE (High Emotion Low Emissions) system, a typically Italian way of saying that it saves fuel by making changes to the car's cooling fan and by stringently controlling the output of the fuel pumps to reduce wastage. This might also pave the way for stop-start to be fitted to the F12.

Carbon dioxide emissions are 350g/km, which are still high but parsimonious by hypercar standards. And hypercar this new Ferrari most certainly is.
