There are now two Lotus F1 teams, as there are two Lotus groups. Team Lotus, the one from last year, were allowed by the Chapman family to use the name. However, Proton, who owns the Lotus that actually makes the Lotus cars, have now bought a stake (or become a huge sponsor of) the Renault F1 team.
Hence we have the schemozzle that is two teams with effectively the same name on the grid. Add to this the fact that if Petrov retains his seat next year, the Renault F1 team will be sponsored by Renault, Lada, Lotus and Proton. What a farce.
And to add my two cents, adjustable rear wings are gayer than Christmas. I love F1, but the rule makers really haven't got a clue.
