There was, but after a short discussion on the Discord it was deleted because it seems the F2 2020 and F2 2021 cars have the same specs, so the difference is just cosmetic.

I think there was a discussion on the discord and the result was, there will be a new category with all new tracks if there are all in the game, till then you drive without the new tracks added after release.
