Hockenheim, Germany: The German Formula One Grand Prix is under threat if the 2016 edition does not attract a large crowd, according to the managing director of the Hockenheim track, Georg Seiler.

The 2015 race in Germany, originally scheduled for Sunday, had to be scrapped because the hosting Nuerburgring could not reach a financial agreement with F1 boss Bernie Eccclestone, and Hockenheim was unable to step in on short notice.

The two tracks have been sharing the German race and Hockenheim has a contract for 2016 and 2018. The Hockenheim race is on the provisional calendar for 2016.

But Seiler told dpa the future of the race is at stake if a trend of dwindling attendance over the years is not reversed next year.

“We need a well filled house next year so that Formula One has a future,” Seiler said. “We must tell the fans: come to the race next year and secure the future of F1 at Hockenheim.”
