Ah, here I go again.
Top:
1. The 2000s Daihatsu Copen, it was a premium in GT6. So, it would be an easy revamp for PD to make. Also neat, PD is adding some K-car action to the game. At least the Copen and S-FRs won't be lonely anymore.
2. What? Another Ford GT? It has to be the LM Spec II test car, I don't think PD would simply model a new model based on either the 2002 Concept or 2004 Spec II race car when revamping the Spec II Test Car would be less time consuming. Yeah, there's no wing visible. However, that could be due to PD hiding it to keep people guessing.
Middle:
1. Another K-roadster, I'm thinking it'll be the Honda Beat. Mainly because of the vent on the door and the front bumper looking a bit riggy like on the Beat. That would make it another standard car premiumized.
2. Wow, another Formula car. Okay, my first guess is the 2004 Formula GT that was last in GT6 as an updated standard. It was one of the standards that got a major model update, so it's possible that PD finished the update to make it a full-on premium this time. Second guess of course is any modern-ish F1 car. Don't know much about F1 other than a few drivers.
3. That looks a lot like the latest Honda K-roadster, the S660. That would be a cool addition if it's true as I can't think of a console racing game with this car in it.
Bottom:
1. That's clearly the Mazda 787B, I figured it wouldn't be too far behind since PD already brought in 3 Group C cars. The headlights match the shape of a 787B, it would make sense due to there already being a premium model from GT6 to update. Plus, it already has competition waiting for it. On the chance that I'm wrong (which happens a lot), it could be the Porsche 962 perhaps. Or the 956 that came before it.
2. I agree with the news page, it has to be a Ferrari 250 GTO. That front end just looks too familiar.
