Audi Sport Italia will field four cars at the fifth round of the International Superstars Series season this weekend at Misano, with young German driver Thomas Schoffler joining the returning Gianni Morbidelli at the wheel of Audi RS4s.

The outfit recently announced that former series champion Morbidelli will re-join the team for the remainder of 2011 as well as 2012 when they introduce their new RS5 model.

Schoffler, born in 1993, has been racing in the Volkswagen Scirocco R-Cup this year. He and Morbidelli will join Ermanno Dionisio and Riccardo Bossi behind the wheel of the team's cars at the Adriatic circuit. Bossi will hope to repeat the fourth place finish he achieved at the Italian championship round at the same track a month ago.

“The Superstars Series is an important part of our history,” said Team Manager Emilio Radaelli. “We’re happy to have Gianni back with us, and I’m sure that the RS4 has a lot of potential yet to show this season.

“We’re looking forward to fielding our new driver Thomas Schoffler, who proved to have already merged with the team. For 2012 we’re developing the new RS5 and we’ll be definitely aiming at the title.”
