There are completed 2015s at the VOA hotel. There are no appearance changes. There were also some 2015s in progess on the line at the Assembly Plant. Any other changes, like added electronic features, are minimal. As for a power increase, other than the long rumored five to ten HP bump from a mild calibration tweak that would likely be avaible to all Gen V owners at the dealer, which I would guess will occur, and possibly the new throttle body material choice, there is none. Perhaps, if they do the five to ten HP bump, it might improve mid range power a tad. None of this is a surprise. Discussions of changes that would have involved tens of millions of dollars of R&D and development costs and an engine recertification which, by itself, is very expensive, were interesting but not realistic.
Later on, perhaps this year by late November or December or next year in the early spring, I would guess we will see a variant with more aggressive aero and a somewhat different suspension available. Why? So they can make another Ring run with a Gen V. It is not easy to improve the ACR's Ring performance further since they were already bumping up against the limits of what can be done with down force versus wind resistance on the ACR that ran the Ring last time without active aero. But I do not think we will see active aero. It is just way too costly to develop.
