May 26 (GMM) Sauber has hit out at Red Bull over cost-cutting in Formula One.
It is believed that every team in pitlane except Red Bull - and satellite Toro Rosso - is keen for the FIA to intervene, enshrining cost-cutting and policing in the official regulations in one form or another.
But Red Bull's Christian Horner claims to have not even read a recent letter to FIA president Jean Todt that was signed by ten of the twelve teams.
"In this sport, foresight is important whenever it is possible," Peter Sauber is quoted by Germany's Sport1.
"One should always think outside the box -- or should I say outside the drinks can?" said the Swiss, in an obvious dig at energy drink maker Red Bull.
"In some cases, people don't care whether Formula One is even here in ten years," the 68-year-old charged.
Monisha Kaltenborn, Sauber's chief executive and one third owner, agrees with her boss that the most financially powerful teams need to be responsible.
"Formula one is not just four teams," she insisted. "For us it is not just the core business, it is the only business -- we are not here to sell another product."
