If there was an update focused on F1 in the future, it would probably be based on the 2012-ish cars, it was datamined a while ago in the Fh5 files and posted right here on gtplanet if I'm not mistaken regarding "Suspension Structures"

, anyways, the cars I want to highlight here are the Ferrari F2012, the McLaren MP4/27 and the McLaren MP4/28.
All of them are from the 2010's (More specifically, from 2012 to 2013) and since Forza Horizon doesn't have F1 cars, we can assume that those files are related to Forza Motorsport.
I'll put the images of all cars here so we can have a clearer view of what these cars are.

The MP4/28 and the MP4/27 are practically the same in my opinion, I got a little confused at first but the more the merrier am I right?
If these cars are added to Forza Motorsport, we can expect to see the Lotus E21 again, it's from the same era after all.
I'll also add a picture of the Lotus E21 here, just for old time's sake
