How big is the newest Forza Horizon 4 Update?

I need to know it, because I have to download it via mobile data because I have no Internet at the moment.
Yea, I really would like to know how big the newest Update is.

Answers are very much appreciated.

If you are talking about the series 8 update, seems it was close to 3gb on x1x

Yea, thats exactly what I meant. Thanks!
