Silverstone bosses say they may be interested in staging a breakaway British Grand Prix next season.
Silverstone might be dropped by Formula One next season
The Northamptonshire circuit faces being axed from the 2005 F1 calendar.
Alex Hooton, chief executive of track owners the British Racing Drivers' Club, said he had heard suggestions about a new, non-championship race.
"That would have attractions as we wouldn't have to pay the fees to Formula One, but there is nothing definite," he told BBC Radio Five Live.
It is not clear whether any of the ten teams competing in the F1 championship would enter such a race, or how it would fit into their calendar.
But Hooton said the BRDC is still focused on trying to keep a British Grand Prix on the F1 calendar, despite supremo Bernie Ecclestone announcing discussions to save the race were over.
"We have to admit defeat and end the discussions," Ecclestone said on Wednesday. "It looks certain there will not be a British GP in 2005."
