Formula 1 will not trial different race weekend formats once the title has been decided, says F1 sporting boss Ross Brawn.
The sport’s owners, Liberty Media, are debating revising the race weekend’s format for the 2019 season.
The bosses want to introduce a four-part qualifying session with four dropping out of Q1, Q2 and Q3 and eight going through to fight for pole position.
This led to some suggestions that Liberty would be open to trialing different formats once either Lewis Hamilton or Sebastian Vettel wrap up the title.
Brawn, however, says that is not on the cards.
“There has been some talk recently about if the championship is won then we could experiment at the end of the year, but the season isn’t fully settled,” Brawn told Autosport.
“Haas is still in a fight with Renault [for fourth] and there are other battles further back.
“So we cannot mess about with the races. The reality is that even if the championship is finished up there [at the front] it is not finished all the way through.
“You cannot just suddenly jump in and say ‘we are going to reverse the grids this week – we are going do this, we are going to do that’. It is too important.”
The former Ferrari and Mercedes man added: “A non-championship race was one idea we had, but the implications of that cost-wise and all the rest of it were really severe,” he said.
“We have to find other ways to work out the impact of new rules. What would happen, for example, if you made it compulsory to have two pit stops. How would that evolve?
“We need the tools to develop it and see what happens, not just jump into it because we think it is a good idea.”
