You can just forget about any Ferrari influence with the HAAS american team.
Forza Rossa will run Ferrari engines, it's connected to a romanian Ferrari dealership, and Colin Kolles will be at the
helm to set it up. So if there is any new team expected to be running Ferrari engines and a Dallara chassis, it'll be Forza Rossa.
Haas has a good partnership history with Honda, so it's most likely that'll be their number one option - however, since
Mclaren is eyeing a solitary position with the Honda engines, this is still up for debate. Then again, one may expect that
the chances of honda having more partners in 2015 isn't unlikely, even more, it's unlikely the new Haas F1 team will be
competing against Mclaren in their debut season, so i think Mcl won't have to be too bothered for Haas to be running F1
engines.
Another option would be the already (partially) developed cosworth V6 Turbo engines, which will get a quick branding as a Ford Ecotec engine. Without doubt Ford would partner up with cosworth and finalize development for a 2015 entry,
so as mentioned, i think Haas will have the option of Ford Cosworth V6T or Honda V6T.
I still reckon the Honda V6T will be the most likely, since you can be 99% positive Forza Rossa will run Ferrari engines, thus if Ford/Cosworth will participate, they'll just be powering 1 team that'll be no doubt a backmarker in their debut season.
Honda however already has a contract with Mclaren, so they already have a team they'll provide, and despite it probably won't matter to Honda much, they'll be keen to be having a 2nd team to provide engines.
and furthermore, i'm doubtfull Gene Haas F1 team will be keen to get their hands on a Ford engine because the former Haas F1 team ran a Lola chassis and Ford engines and was even less successful than HRT.
I can see Haas wanting Mercedes engines, but i'm doubtfull Mercedes is willing to provide even more teams with engines.
Its funny though that Haas' f1 team will be named "Haas Racing Developments" in short is HRD, just 1 letter difference with HRT.
Anyway, Dallara will be eyeing to correct their 'name' in f1 after the Campos/HRT disaster. Fact is though, dallara never was at that much fault, Campos didn't pay and they didn't finish. Only last-minute they got a chassis which essentially was an 'unfinished' prototype. Didn't they run aluminum brakes instead of carbon? General build quality was extremely bad. I actually dare to say that i think the Dallara chassis was (designwise) not that bad actually. Concidering the fact that the exact same car ran for 3 seasons (2010,2011,2012) and having an 'underpowered' cosworth engine still managed to keep close to the financially much healthier and developing virgin/marussia and lotus/caterham team, i think Dallara really didn't do too bad at all.
After all, they finished both 2010 and 2011 in front of the financially much healthier virginF1 team which became marussia.
(WCC standings).
so to be fair, Dallara has a lot of potential which hopefully this time will be put to use. I know ferrari has been mentioned as a link to Haas, but i'm still doubtfull about that.
So imho, Haas Racing F1 Team will be running Honda engines with a Dallara chassis, competing against Forza Rossa F1 - Ferrari of Kolles' and batteling against Caterham and Marussia, though the existance of both latter teams may be doubtfull since Marussia has been eyeing a fusion with Toro Rosso and Tony Fernandes said he might kill the project if they aren't scoring any points this year , and i can't see that happening yet.
so chances are there are 2 new F1 entries for 2015, but that doesn't guarantee 4 additional cars on the 2015 grid compared to 2014. It may be just the same amount of cars. Though i'd like to see 26 cars on the grid.
