Audi's DTM champions Mike Rockenfeller and Timo Scheider will be teammates in the 2016 edition of the Nurburgring 24 Hours.
The duo will pilot an Audi R8 LMS for Audi's new customer team Land-Motorsport, with former FIA GT champion Marc Basseng and Porsche Supercup regular Connor De Phillippi joining the line-up.
For 37-year-old Scheider, DTM champion in 2008 and 2009, this year's Nurburgring 24 Hours will mark his return to the event for the first time since 2011.
Scheider has one win in the event, dating back to 2003, when he, Manuel Reuter and Marcel Tiemann recorded Opel's first and only victory in the endurance race.
For 2013 DTM champ Rockenfeller, his sole Nurburgring win so far also came with a different manufacturer - Porsche in 2006, with Lucas Luhr, Timo Bernhard and, again, Tiemann.
Rockenfeller, who also has a Le Mans 24 Hours win to his name, was part of Audi's Phoenix Racing set-up in last year's race, albeit the car retired halfway through.
Basseng, 37, is yet another past winner in the line-up, having been victorious in the 2012 edition. He and Scheider previously teamed up in a Land Motorsport Porsche in the 2006 race, but did not make the finish.
De Philippi's first start in the Nurburgring 24 Hours came in 2015 as he finished 19th overall - and runner-up among the SP7-class entries - in a Frikadelli Racing Team Porsche.
