When I switched off the engine, I could hear some air pump noise when I stood near the rear axel. What was it doing? Pumping up or pumping down? or is it something else making the air pump noise? I couldn't tell easily.

I thought the reason they added the air suspension was for the comfort. On the other hand, as the rear axel has the air suspension already, why doesn't it offer changes to the stiffness when changing to Sport mode?

The F01 does have the same self-levelling air suspension at the rear axel. The F07 and F01 are the only two cars with this wheelbase of 3070mm. How does the auto-level works? Why is it only necessary in a longer wheelbase car, why only the rear axel?
