The PR shutters are down at Renault and Caterham right now, with neither willing to utter so much as a word on the imminent ending of their joint venture. Believe me, though, the relationship has disintegrated and its dissolution is only a formality.

Given the reluctance to talk, what I should stress up front is that - unlike the news story - this is a blog based on hunch and hearsay as opposed to hard facts, but I feel it is worth writing because the naysayers are already jumping on the bandwagon, predicting the end of Caterham.

I’m not so sure, however. While Tony Fernandes’s plans for the brand undoubtedly remain at the ambitious end of ambitious - a cash-eating Formula 1 team, a new family of sports car, a range of SUVs - I don’t see this latest split as anything remotely as dramatic as the end of the brand.
