The Chiron, Centenario, FK8, 2020 'Vette, CCX, Quattro, and Demon are probably the best bets for possibilities of what will arrive next in Heat. Despite how much I love and pretty much every NFS fan loves Supras, I don't think that there's a fighting chance that any Supra will make it into Heat. Additionally, I don't believe any more McLarens will be added for a variety of reasons:
- Ghost probably is satisfied with their selection of McLarens for Heat.
- There already is the 600LT and 570S (which has two variations).
The Raptor Ranger most likely won't make it as it's not yet as iconic as the F-150 Raptor. Even though the Ram SRT-10 is an incredible truck, it doesn't really fit in with the current lineup of cars in this generation of Need for Speed. However, if this had been NFS: Underground that we were talking about, then yes, the SRT-10 would most likely make an appearance in an updated version of the game.
Reasons for why the Abarth won't make it:
- IT'S A FIAT. Never in NFS history has a car with less than three cylinders made an appearance, with the exception of the Audi A1 Clubsport Quattro Concept, Mazda RX-7, and Mazda RX-8. However, all three of these cars had rotary engines.
- No car with a displacement of less than one litre has ever made an appearance in NFS. It's very unlikely that they would start with that now.
- This isn't Forza. The daily drivers that NFS includes in their car lists are higher-performing icons.
The 2018 Mustang probably won't make it in either, because we already have the 2015 Mustang GT.
The Jeep Wrangler won't make it in either because it's not really the style of Need for Speed.
The 2015 Ram won't make it because we already have two versions of the F-150 Raptor in the game.
The 16.4 Grand Sport Vitesse won't make it in because it's now considered to be an outdated car. Need for Speed stopped including cars like the Agera in favour of the more updated models produced by brands like Koenigsegg. The same goes for the '05 Ford GT. The '05 GT stopped showing up in Need for Speed the second that the 2017 Ford GT was released, though it has made an appearance in NFS: No Limits. But once again, that's NFS: No Limits, where you have to waste hundreds of dollars just to properly compete.
Lastly, the Passat, new Beetle, and Arteon will probably never appear in game other than as traffic cars because they're not performance vehicles like every other car in the game. They're not really that big in the tuner scene.
Note: This is not me * on your list. You have some very strong cars in your list that I would most certainly select as my personal candidates for future updates. I am just being realistic and analyzing your list based on the history and vehicle choice of past NFS games.
