That may have been it. I've heard that the split had something to do with marketing or merchandising. LR8 might have been it. But Lotus Cars will most likely argue that because the licencing agreement was breached and terminated, they no longer want to have anything to do with Tony Fernandes and his team. Therefore, by calling themselves Team Lotus, they are still associated with Lotus Cars, even if they have the legal rights to the Team Lotus name.
