The DTM will continue to race at Spielberg until at least 2016 after sanctioning body ITR signed a new three-year deal with the circuit.
The series returned to the Austrian circuit in 2011 following a seven-year layoff and this year attracted a weekend crowd of 44,000 for its event. ITR chairman Hans Werner Aufrecht indicated that the Red Bull-owned circuit's facilities, including the grandstands and parking lots, would be improved in time for next year's race, following heavy rain this year.
"Spielberg has got the advantage of being a circuit embedded in the environment, thus automatically making for great motor racing," Aufrecht said. "That's one of the reasons why we love to race at Spielberg. Another one is the great organization that is absolutely on the level it takes today for holding professional motorsport events.
"At the same time, we also have the DTM fans in mind. We want to provide them an even better and nicer experience, during our coming race meetings at the track. And to be able to do so, we wish for roofed grandstands and an improved parking-area situation."
This year's race was won by Bruno Spengler, who headed an all-BMW podium that also included DTM rookies Marco Wittmann and Timo Glock.
