I was thinking the same thing about Honda not that long ago. F1 is a disaster. They're slowest in GT500, struggling in GT300. They're having a sub-par season in Super Formula. They're getting worked in WTCC (but so is everyone else I suppose). I don't really follow Indy, but the little bit of the 500 I payed attention to, it sounded as though Honda was down on power compared to Chevy.
I'm probably wrong, but 2015 seems like the worst year for Homda motorsports that I can remember
Even going back to the 2014 Suzuka 1000km, I remember the English commentators at Radio Lemans mentioning how Honda was struggling with the new NSX in GT500, and how their poor showing on their home track could have reprocusions within the organization.....I don't think they thought things would get drastically worse
Could it be the F1 effort which is detracting from all their other programs?
In my humble opinion, screw F1 >.<. Honda would be better served by building a GT3 spec NSX, stepping up all levels of their Civic programs (WTCC, etc), and then step into WEC in 2018-2020.
I'm so infuriatingly bored with F1, I seriously hope the series completely dies off (never happen, but I can dream)
Edit: just to add. I don't really follow BTCC because I can't find coverage (live in Canada), so not sure how they're doing there. Aside from that, the only Honda I can think of with remote success in 2015 is the Acura competing in PWC, and it's a top 10 threat, but not a consistent podium contender.
