Jamie Green has been placed with Abt Sportsline for his maiden season with Audi in the DTM.
The 30-year-old Briton confirmed last December that he was switching to the Ingolstadt marque after spending eight years with Mercedes.
He was announced as one half of a pairing with two-time champion Mattias Ekstrom for the 2013 season following at the Geneva Motor Show.
Timo Scheider and Adrien Tambay will fill the remaining spots at the four-car Abt team, as they did last year.
Edoardo Mortara and Filipe Albuquerque remain as the Team Rosberg line-up while Phoenix Racing's Miguel Molina and Mike Rockenfeller stay put as well.
Audi also announced that its A5 DTM will be rechristened the RS5 DTM for the coming season.
