Only after my initial post I realized I could test it myself.

This is how it works for me and I believe it is like this since I started playing this game during Track To Tarmac in november 2017.

I started with 3Drive and a refill for 2GC will get me 2 drive.

I can upgrade to 4Drive for 20GC and a refill for 2GC will get me 3 drive.

After that I can ugrade to 5Drive for 40GC and a refill for 2GC will get me 4 drive.

The time it takes to refill 1 drive is always one every 18 minutes starting when you use the first one. (Ex. you race 3 TT's of 3 minutes each, you have to wait 9 minutes for the first drive to be refilled, and 27 and 45 minutes for the 2nd and 3rd one).

Also when you ugrade your Maximum Drive, your drive will get refilled to the max, so best is to upgrade your drive when you have none left. This way you could race 12 TT's without waiting or spending gold on refills.

I hope I explained it right and it is clear for anyone in search of this information.

Also I would be very interested to hear if it is different for other players.
