Mattias Ekstrom topped the second DTM free practice session at Zandvoort after a blistering lap in the closing stages on Saturday morning.
The Swede had been quiet for most of the session, but he emerged for a flying lap with five minutes remaining, and eclipsed Audi teammate Timo Scheider's best effort by four tenths of a second.
Scheider and Miguel Molina completed an Audi top three, continuing the manufacturer's strong performance from Friday.
Ekstrom aside, the Mercedes drivers were able to mix it with the Audis this time. The session appeared to be turning into an Audi walkover, until Mercedes sent its drivers out to up their pace with half an hour to go. The top Audi runners responded, before Paul di Resta, Gary Paffett and Bruno Spengler all got themselves back into the top six in the closing moments.
The top 10 was completed by 2008-spec cars, as the Audis of Markus Winkelhock, Alexandre Premat and Mike Rockenfeller headed Jamie Green. Ex-Formula 1 drivers Ralf Schumacher and David Coulthard ended the session in 13th and 14th places respectively.
Schumacher had been mixing it with his HWA-Mercedes teammates for most of the session, but he elected not to join them in doing a final run which left him down the field. Coulthard spent most of the session in the middle of the time sheets, but he lost some track time after an off-track excursion through the grass.
