Renault's director of engineering Pat Symonds has joined calls to modify the third part of the current qualifying format.
The new knockout system has proved generally successful among fans and teams, but the third session, where drivers just burn off fuel for 20 minutes before setting their fastest times in the end, has been subject to criticism.
Symonds believes the current system is good, but reckons the final part needs to be improved.
"I think we can improve the qualifying format even further," said Symonds. "After the last race in Malaysia, I had the chance to watch the qualifying session on television, and I felt there was room for improvement.
"From the pit-wall, you really don't get a feel for the show because there is so much to do.
"But watching with some commentary, I think we can tweak the final part of qualifying. The first ten minutes of the third section have very limited interest: the cars are just going round in circles to burn fuel."
