McLaren team principal Martin Whitmarsh has called on the F1 fraternity to be more proactive when it comes to rule changes and cost-cutting.
Formula One will switch to new generation V6 turbo engines in 2014 and with the change will come an increase in expenses. The smaller outfits like Force India have already raised concerns about the rise in costs.
Whitmarsh, who doubles up as the chairman of the Formula One Teams' Association, warns that that the sport needs to be more diligent when it comes to changing regulations.
"There isn't a silver bullet here," he told Autosport when asked how teams can do a better job when it comes to decision making.
"We have got to be a bit more diligent in how we pull things together, recognise the implications and work harder at cost saving in F1.
"McLaren, in recent years, has shown it's less critical [financially] but we need to make sure that the sport is healthier than we have made it at the moment.
"We need to have 10 or 11 teams that can survive and have sustainable business models.
"People have got to be more proactive, earlier on rule changes and how we develop cost-cutting in F1."
