Ross Brawn has said that he would like to introduce an annual 'non-championship' race so that Formula 1 can experiment with new weekend format ideas.
The former Ferrari and Honda chief, attending the Barcelona test, is Bernie Ecclestone's replacement on the sporting side after the Liberty Media takeover.
He said that F1 has been too "reactive" in the past, implementing ideas without fully thinking through the consequences.
"I have an ambition that we could have a non-championship race to experiment with the format and see what appeals to people because all of us are the same -- we don't always know what we would enjoy until we experience," Brawn told The Times.
The 2017 calendar begins on March 26 in Melbourne.
