In general, drivers have given the idea a cautious welcome.
Some bigger teams wanted a raise to the budget cap limit in order to compensate for the risk of extra damage incurred during Sprint, but other teams felt they were pushing the financial boundaries for their own gain and Sprint was just a pawn in this exercise.
For the revised qualifying session on a Friday, only soft tyres will be available to the teams, meaning that the top 10 runners will no longer have to start the race on the set of tyres on which they made it through Q2.
So Friday night we know the grid for Sunday.
Regular qualification for a Grand Prix works on a knockout basis over three rounds, all held on a Saturday.
This will continue to apply in the standard qualifying session before sprint qualifying.
