If you head over to www.android.com/auto and select Alfa Romeo you can see that the Giulia and Stelvio are both listed as "coming soon" for 2018+ MY.
I think this pretty much seals the deal then here IMO. Unless it's a 2018 onwards car were not getting Android Auto (or presumably Apple Carplay...
Apologies if already covered, but supposedly the Yanks - and I would think everyone - are getting this set of updates soon:
MY2018 Product Enhancements - Alfa Romeo Giulia Forum
- CarPlay and Android Auto
- a new set of 18" wheels (hmmm)
- HK audio as standard on the QF
- various other tweaks...
