Winkelhock was displaced from the Audi line up for the German touring car series, Deutsche Tourenwagen Masters, after his poor, 12th place finish in the 2010 season. Winkelhock will join the team boss, Marc Basseng while Nicky Pastorelli and Dominik Schwager will headline the second car.
Basseng commented: "I think with this driver package and all the gathered experience from 2010 we should be able to drive at the front and get some victories this time, even if the competition is quite bigger than last year."
Meanwhile, Swiss Racing Team have announced their third driver ahead of next weeks season opener. The team have sold on their Nissan GT-R racers and switched to the ex-Blancpain Lamborghinis.
The team have also gone ex-Reiter/Blancpain for their third driver with Peter Kox. Kox drove the #24 Reiter car in partnership with Chrisopher Haase through the 2010 season. He will be paired with SRT Nissan man Karl Wendlinger.
"We are glad to have Peter in the team," said Othmar Welti. "He is a great driver and has a lot of racing experience in Lamborghinis. He is a big asset for all of us."
Max Nilsson will drive the #6 car along with an unspecified team mate while #5 will be entrusted to the new Kox/Wendlinger partnership.
