This weekend's Download festival showed how well Donington Park can cope with the increased demands of a Formula One crowd, according to its promoter.
Up to 135,000 heavy metal fans attended the festival, which featured ZZ Top, Whitesnake, Def Leppard, Slipknot and Marilyn Manson.
It was the seventh year the festival had been held at the race track.
Simon Gillett of Donington Park Ventures said it showed the site's management systems could work well.
He said: "It's actually a great way to demonstrate what we can do ready for Grand Prix.
"People say, 'How will you get a Grand Prix crowd in here without cars?'
"Well, look what's happening here - we've got 100,000 people and there's not a car on site."
Donington Park secured a 10-year contract to host the British Grand Prix at the expense of current hosts Silverstone and is due to stage its first Formula One Grand Prix since 1993 in July 2010.
