The FIA wouldn’t have had a hope of holding up the ban on Honda developing in year if it was taken to court given that it’s clear that the intention of the rule was not to do that. As usual, drama created by poor rule making.
Anyway, it’s great that it’s been sorted in a (IMO) fair way now.
As to Honda’s performance, I’d love to be wrong but I just can’t see that they’ll produce a Merc beater right from the start. Just because they know the performance of the Merc engine doesn’t really give them much help – they all know the aero performance of say RB but that doesn’t mean they can replicate it and aero is much more visible than engine components, etc.
Not to mention that real world experience is massively beneficial and all the other engines will have moved on from 2014.
I’d reckon on a decent engine but not quite up to Merc which they can develop and get more on parity come 2017 and beyond.
