Why does my Audi A8 have reduced power at high altitudes?

I recently took my Audi A8 up to a higher altitude and noticed that it had reduced power and struggled to accelerate. What could be causing this?

This is a common issue with high altitude driving. Due to the thinner air, your engine may not be getting enough oxygen to achieve optimal performance.

You may need to get your car's engine computer reprogrammed for higher altitudes to adjust the air-fuel mixture. This is a common solution for performance issues at high altitudes.

Some drivers also recommend using premium fuel at high altitudes to help combat reduced power.
