Ferrari president Luca di Montezemolo has voiced further criticism about the raft of radical rule changes that the FIA announced earlier this week.
As well as unveiling plans for a voluntary budget cap from the start of 2010, the FIA has shaken up Formula 1's points system - declaring that the world championship will be handed to the driver with the most wins.
The changes have already drawn critical comments from former champions Fernando Alonso and Michael Schumacher, and di Montezemolo has spoken out again too.
"I really think it's absurd, severe and dangerous that one week before the first grand prix, Formula 1 is in such a situation, which is very bad for its credibility, its security, the teams, the car manufacturers, the fans, the journalists and the sponsors who invest," di Montezemolo was quoted as saying on Ferrari's official website.
"I hope for a responsible climate, which has been started by us, the teams, with a cost reduction of 50%.
"It's important to have a serene climate and to avoid continuous changes, creating uncertainty for those who work and making decisions for the future difficult."
Di Montezemolo made his comments during a visit by Italian president Giorgio Napolitano to Ferrari's Maranello factory.
