I'd like to know something about "McLaren’s internal Vehicle Performance Index"...


To generate this "Performance Index" do they use International System of Units or Imperial Units?
Which number is "better": 3.1415926535 or 69?
I'd like to know Performance Index of a P1, a Ferrari 458 and a Zastava Yugo.

I know how to combine kW and kg... But how to combine it with aerodynamic efficiency? Are we talking about Cx or SCx?

Emissions... OK!
Carbon monoxide? Carbon dioxide? Hydrocarbons? Oxides of nitrogen? All of them?
