Mercedes, Red Bull and McLaren bosses, whose teams were the top- three in Formula One last year, have given their backing to proposed Saturday sprint qualifying races.
The sport is expected to confirm the experiment, which would award championship points on Saturday as well as in Sunday's race, for a limited number of the season's planned 23 grands prix.
The sprint race would effectively serve as qualifying for Sunday's main event. The teams are due to have further discussions in Bahrain this weekend.
"There's always a million reasons why not to do something, but I think the concept's interesting," Red Bull boss Christian Horner told reporters on the first day of pre-season testing on Friday.
