A Formula One proposal for an experimental reverse-grid qualifying race when Austria hosts two grands prix in July looks unlikely to be accepted due to opposition from champions Mercedes.
Spielberg's Red Bull Ring is due to start the season on July 5 with a second race there, also without spectators, a week later.
Team sources confirmed the proposal was made at a meeting on Friday with commercial rights holders Liberty Media, the governing FIA and the competitors, and Mercedes were unconvinced.
A vote is expected after Formula One publishes its revised calendar early next week, and unanimity is required.
