One possible solution to the mystery of the 20th race in 2013 could be the Red Bull Ring in Austria. This is only 250 miles from Budapest which means that the F1 circus could move between the two tracks fairly easily and it is possible that a multi-squillionaire such as Dietrich Mateschitz might like the idea of hosting an event, even if it is only a one-off to help Bernie Ecclestone get the 20 races he wants. Each new race on the calendar means that the teams get extra money so in some respects Red Bull would be getting some of the money back.
The circuit was reopened last year after a major rebuild from its days as as the A1 Ring. Prior to that it was known as the Osterreichring and hosted Grands Prix from the 1960s onwards. It was a popular venue. It has not been used for an F1 race since 2003 and the infrastructure in the region is poor, but Sebastian Vettel recently said that he could imagine a Grand Prix being staged there. Red Bull’s Dr Helmut Marko added that “with Mateschitz, you can never say never. Let’s see how it develops.”
