Augusto Farfus kept BMW on top in the second DTM practice session at Brands Hatch on Saturday morning.
The Brazilian, who took his maiden series podium last time out at Lausitz, set the pace in 41.312s in his RBM M3, over a second quicker than Martin Tomczyk's Friday best.
Mattias Ekstrom served notice of Audi's intent to recover from its poor start to the season with the second quickest time for Abt Sportsline, just 0.035s behind, while champion Tomczyk was third, 0.051s off Farfus' time.
Championship leader Gary Paffett was the best of the Mercedes drivers in fourth, but the HWA man suffered an off identical to the one he had on Friday, the Brit going straight on at the left-hand part of Surtees and cutting across the grass as he headed towards the pit entrance.
Miguel Molina was fifth quickest in his Phoenix Audi and was within 0.1s of the best time. Fellow Audi men Timo Scheider (Abt) and Edoardo Mortara (Rosberg) were next up.
Jamie Green, who put two wheels into the gravel while exiting Paddock with a few minutes to go, was eighth for HWA while Mike Rockenfeller (Phoenix) and Adrien Tambay (Abt) completed the top 10.
Andy Priaulx was 19th in his RBM BMW, with Mercedes pair Susie Wolff (Persson) and David Coulthard (Mucke) taking the final two spots, albeit both still within 0.9s of the pace.
