Pardon the double-post, but I did some digging, and I think I can put my finger on what happened - and when - between Fernandes and Group Lotus:
I think the dispute was over LR8 ("Lotus Racing 8"), an energy drink that Team Fernandes was developing. It never went to the market; the idea was that it would be the "official drink" of the team, and it would only be sold
through them. It wouldn't see the conventional market the way the likes of Red Bull and Monster do. But the LR8 logos were pulled from the T127 halfway through the season, to be replaced by a tobacco-style self-censored design, a Rothmans-esque question mark. I suspect that if you look closely enough, the LR8 decals were pulled at about the same time Group Lotus started making noises about Fernandes being in breach of his licencing contract. The contract stated that Fernandes could only use the Lotus name for the team. Group Lotus' argument in court likely centres around Fernandes' plans to sell LR8, which was not an approved use of the name; Fernandes would counter that because the product was only intended to be sold through the team, he wasn't actually doing anything wrong.
Now for the real kicker:
this is the last picture I can find of a Lotus carrying the LR8 logo - it's Heikki Kovalainen at Spa, which was held on the weekend of August 29.
This picture, on the other hand, is Jarno Trulli at Singapore (I can't any clear side-along shots of the car at the Italian Grand Prix), which was held on the weekend of September 26. You can clearly see that the LR8 logo has been replaced by the question mark. Something changed in the space of a month. I don't recall any explanation being given, but a quick check of the archives reveals
this article about Group Lotus sponsoring ART Grand Prix in GP2, and
this one about Fernandes establishing Team AirAsia, the very first signs that Dany Bahar was moving away from Tony Fernandes. And the date on both? September 21st, four days before the Singapore Grand Prix - the earliest recorded date the LR8 logo stopped appearing on the Lotus T127. Group Lotus and Tony Fernandes going their separate ways in GP2 the same week that a merchandise logo stops appearing on the Lotus Racing Formula 1 car is a
massive coinkydink. I'm willing to give you good odds that LR8 is pivotal to the court case between the two parties.
Now, Saward reckons that Fernandes intends to keep Caterham and Team Lotus entirely separate from one another and take the Seven to Asian markets – but I’m not so confident. We’re just weeks out from a final verdict in the court case, and all of a sudden Fernandes purchases a small sports car manufacturer with historical ties to the car company he’s locked in the legal dispute with? And he does it in such a way that it is a week before anyone finds out about it? Come on, that’s a massive sequence of coincidences that have to stack up on top of one another. Too many, if you ask me. Especially since Fernandes is the kind of guy who loves to make big statements to the world (and small ones, which he dresses up as big). Maybe it really is Fernandes’ intention to take the Caterham Seven global (and I applaud that – it’s a fantastic little car) … but you can’t deny that it’s also a convenient out in the event that he does lose the court case against Group Lotus.
