The newly-announced Formula 1 qualifying format has hit another speed bump, after drivers spoke out against the plans.
The elimination system of qualifying has brought controversy to the sport after it was agreed by teams and F1 chiefs.
In a meeting with F1 race director Charlie Whiting, many drivers voiced their opposition to the changes. Following the discussion, driver Sergio Perez told Sky News: "We are obviously not very happy with the new plans they want to implement. Let's see if they can change it.
"We felt that it would be very complicated for the fans to understand – it's complicated for us already.
"We also felt that qualifying is really good at the moment and there is no reason to change that."
Bernie Ecclestone has already admitted that the plan would have to be setback until the Spanish Grand Prix, as it would be impossible for the timekeeping systems to be set up in time.
Renault driver Kevin Magnussen admitted that without knowing exactly what the rules were, it was much harder to prepare for the new season. Telling Motorsport.com, he said: "Yeah, obviously it would be better to know, and easier to prepare.
F1 team managers have agreed that a small change to the rules would allow the system to remain in place despite the difficulties with timekeeping. However, with each change requiring a fresh vote – and a unanimous approval needed for it to go ahead – F1 chiefs are running out of time to bring in the new rules for the coming season.
