Red Bull Racing's Christian Horner isn't convinced eliminating Friday's track action would deliver a benefit to Formula 1.
As the sport prepares for transformation, both on the commercial and sporting fronts, with future calendars likely to include in excess of 21 races, Formula 1's management is thinking of reducing the current format to a two-day event.
While the idea is still in its early stages, not everyone is on board with the concept.
"Obviously they're trying to free up space for more races," Horner responded.
But the Red Bull boss thinks the F1 calendar is already close to saturation point with the current number of races.
"If there's too many chapters, a good book loses its path," said the Red Bull chief.
"I also think it would be a long way to come to Mexico for two days. Or Australia. And I think the Friday gives the promoter the opportunity to bring more fans into the sport," he added.
Horner also thinks the two-day format would hurt the teams, in a sport where track testing is already extremely limited.
"Perhaps it will inadvertently put more pressure back on simulations so that you're turning up prepared to hit the road running, and I'm not sure that's going to be a great balancer between the teams," he said.
