Renault boss Flavio Briatore thinks his team's hopes of winning the title this year are all but over now in the wake of the FIA's decision to approve the use of double-decker diffusers.
The Italian thinks that it will take too much time for Brawn GP, Toyota and Williams's rivals to catch up with the diffuser gang and has questioned the credibility of the the world championship because of it.
"The drivers in our teams have been and are world champions, while the championship is now fought between a driver who was almost retired and another one who is a good guy but a paracarro
(Italian saying for being as slow as a milepost at the side of a road)," Briatore told Gazzetta dello Sport
. "I don't know where credibility has ended up with all this. To make up the gap we have to those teams is impossible."
While rival teams now set about working on their own double-decker diffusers, Briatore is convinced that the three teams who already have the concepts well honed will pull out enough of a title advantage in the next few races to secure the crown.
"In three or four grands prix, the title will be already decided, and I can't see what interest TV and spectators can have in seeing a race when Button has 60 points, [Kazuki] Nakajima 50, and someone else 80: it's better to listen to a race like that on the radio, and watch anything but that.
"Just when there's talk of setting a budget cap to 30 million, we've spent $15m for KERS and $10m more for the diffusers. We're left with $5m to travel and to pay the employees."
