Formula One Team Association (FOTA) Chairman Martin Whitmarsh is not in favour of teams fielding three cars in the Grand Prix, saying it may destroy the smaller outfits.
At present 12 competing teams can field a maximum of two cars but big teams such as Ferrari have been pushing hard to have three teams.
Ferrari President Luca di Montezemolo had even suggested sarcastically that smaller team should go to compete in GP2 if they do not have the money.
"We have a duty to support the sport and the teams. It will probably destroy the smaller teams. Red Bull McLaren, Ferrari, and may be Mercedes can possibly do it, but if we manage the sports badly, the number of teams may drop to eight," Whitmarsh said in an interaction with a group of journalists.
"There should be sustained business for all teams," he added.
It was reported that FOTA was discussing the idea with FIA. FIA boss Bernie Ecclestone had also reportedly shot down the proposal.
