Formula One's Sunday qualifying has been axed in favour of a one-session, one-lap format, starting from next week at the European Grand Prix.
Qualifying will take place on Saturday over a one-hour session, involving a single timed lap, according to the sport's governing body, the FIA.
Grid postions for races, up to this point in the season, had been decided by the times from Saturday and Sunday.
Many drivers had made clear their dislike for the two-day format.
Changes were afoot as a result of F1's 10 teams unanimously agreeing to change qualifying procedure.
FIA president Max Mosley had also given his seal of approval to the plans.
"It's very important to have the grid sorted out on Saturday," he said. "It irritates the public not knowing who is on pole.
"If you follow a particular driver and you know he's going to be on pole you might change your plans for Sunday.
"But on the other hand if you know he's at the back of the grid you might go and do something completely different.
"People need to know - it's no good telling them two hours beforehand."
Teams would be unable to refuel the cars or modify them between qualifying and the race.
The running order would be the same as it is at the moment on Saturday, with the winner of the previous race having the advantage of going out last.
