Timo Scheider topped the final DTM free practice session at Oschersleben on Saturday morning.
The two-time champion took the top spot with three minutes remaining in the session, ending a tight contest that developed between Audi and Mercedes in the closing stages.
It was Mercedes that started the flurry of activity. Its three title contenders, Bruno Spengler, Gary Paffett and Paul di Resta, took the top three spots when they all did short runs with 25 minutes to go.
Paffett then knocked Spengler back when he did a second flying lap, but they were all eclipsed by the 2008 Audi of Miguel Molina 13 minutes from the end.
Mattias Ekstrom also joined the fray but could not quite go quickest, while di Resta later had another go as well but just missed out.
Martin Tomczyk appeared to have sealed top spot when he found a lot of time with eight minutes left. However, he was eventually pushed down to third by two-time Oschersleben winners Scheider and Paffett.
Molina, di Resta and Ekstrom had to settle for completing the top six, and behind them Alexandre Premat pulled himself up from the bottom end of the field to take seventh.
Spengler's earlier pace-setting effort was good enough for eighth by the end, while Ralf Schumacher and Mike Rockenfeller completed the top 10.
