I am privy to some more information that I would shortly share. It seems there are serious devisions in RBR about whether to appeal the decision or not. All is not well at Viry too it seems. I am afraid things are not looking good at the moment. The only team holding back almost all Renault teams is the engine. Having said that the fact that Renault identified their problems before homologating, they have had time to apply potential fixes before they submitted their design. Ferrari on the other hand, is a hopeless case of going/being no where. Given that Ferrari could have supported Renault to lift the engine freeze, in hindsight Ferrari misread it completely. Mood at Renault is not upbeat, but plenty of promise that they are finding hard to unlock. What works for RBR is not working for Lotus. For now all focus on RBR.. so unfortunately Lotus issues taking a backseat.
A bit off the topic, I see them matching up with Honda for 2015 as it has been reported months ago.
