The future of the Britcar 24 Hours at Silverstone is believed to be in doubt.
Britcar Director James Tucker told The Checkered Flag that though the 2012 event (September 21-23) will go ahead future editions are in doubt. He confirmed that the problem is not related to any noise concerns from residents of the surrounding villages.
The Britcar 24 is the UK's only 24 Hour GT race. Under Tucker's direction it was first run in 2005, though the 2009 event was shortened to 500 miles due to cost concerns for competitors.
Since its inception the race has attracted international teams including top names such as Duller Motorsport, ARC Bratislava and Jet Alliance Racing, as well as UK based works entries from Lotus and Ginetta.
The 2011 race was won by the Eclipse Motorsport team of Phil Keen, Michael McInerney and Sean McInerney who beat a 50 car field in front of a reported crowd of 14,000.
