I spotted a typo. There is 25% less air not 75% less oxygen. But mistakes happen.
Sources indicate that the atmospheric airpressure at 2000m is about 75% of the pressure at sealevel AND the relative amount of oxygen in the air decreases from 21% at sealevel to 16.5 % at 2000m. Meteo is not my thing but multiplying these two results in 40% less oxygen at 2000m. If that is correct, it is far more than I would have guessed. I guess they will cut some holes in the bodywork to suck in more air.
Think about that figure though. Can humans survive comfortably on 40% of the oxygen that they normally breathe?
Hehe
Here I did the work for you.

In Mexico City, a cubic meter of air contains 212 grams of oxygen, while at sea level it contains 275. The combustion efficiency of a well-tuned car is 92 per cent, and in the DF 69 per cent, due to the higher altitude.
So the oxygen density in the air is about 77% versus sea level.
Also from other articles, the oxygen concentration inside the lungs of people is actually about 90% versus sea level.
Note for an F1 engine the combustion efficiency will not drop much due to turbocharging. The turbochargers will only spin faster to make the same boost.
