Red Bull will be disappointed not to of got more out of the test, but they will of extracted enough aero data to work with it, and they now know they have a heat issue. Something which would be a lot worse in some of the other tracks. They will no doubt have a solution for this already, but they will have to balance the fix with cooling capabilities, and aero performance loss.
Renault will no doubt change what they can, but I would expect the fault isn't with the engine. They are a magnificent team, with a lot of talent. They'll be annoyed about this, but it isn't the end of the world for them. If they are still suffering major issues at the next test then it might be a cause for concern.
What we do know, is Mercedes have created a reliable package, and Ferrari haven't done a bad job either.
