Formula 1 fans will known later this week whether reverse grid qualifying races will take place next season with F1 bosses set to vote on it on Wednesday.
In a bid to spice up the show, F1 owners Liberty Media want to introduce reverse grid qualifying races in 2020.
The plan is to run three – Paul Ricard, Spa and Sochi – as an experiment.
Instead of qualifying as it is now, drivers will line up on a Saturday afternoon in reverse championship order and run a sprint race.
The result of that will determine the grid for the Sunday grand prix.
“If it’s not unanimous, it will not happen,” Haas team boss Guenther Steiner told Autosport. “And I don’t know if these people will be convinced, but that is a decision for Wednesday.
“There was more than once that somebody didn’t want something, and then still it happened.
“So I wouldn’t get ahead of myself and say it is not going to happen. There are people which have got opinions, concerns about it.
“But the decision is on Wednesday, so let’s see what happens on Wednesday.”
