Apr.14 (GMM/Inautonews.com) The real motive for Lotus’ protest against the Mercedes ‘double-DRS’ may be emerging.

A rumour in the Shanghai paddock is that the former Renault team, despite apparently pushing the FIA to ban the concept, could be planning an even more radical version of the aerodynamic-stalling idea.

Lotus surprised the F1 world by electing not to send the FIA’s decision to definitely allow the Mercedes system to the international court of appeal.

“Now that the FIA has taken a clear position,” team boss Eric Boullier told L’Equipe, “it must be respected.

“The advantage is that this situation has opened the door to solutions that could be much more interesting,” the Frenchman added.

Technical director James Allison confirmed that, rather than pursue avenues for having the Mercedes concept banned, Lotus will now “get on with looking at what possibilities are open”.
