Christian Vietoris maintained the Mercedes stronghold at Circuit Park Zandvoort, as the Mücke Motorsport driver topped the timesheets in the final free practice session of the weekend.
Vietoris set the best time of a 1:31.569 around the 4.307-km circuit, 0.158 seconds ahead of Audi’s Miguel Molina, with Mattias Ekström completing the top three.
Audi Sport had a better showing during the 30-minute session, as Jamie Green, Nico Müller, Edoardo Mortara Timo Scheider made it six RS5s in the top ten.
Yesterday’s race winner Robert Wickens was the next best Mercedes driver in seventh, ahead of Paul Di Resta, as Scheider was 0.670 seconds off the pace set by Vietoris in tenth place.
Bruno Spengler was the fastest of the BMW drivers in eighth whilst Maxime Martin missed out on the top ten by just 0.004 seconds, ahead of Augusto Farfus.
Mike Rockenfeller, who won the title here at Zandvoort back in 2013, was 13th fastest, ahead of the Stuttgart trio of Maximilian Götz, Daniel Juncadella and Lucas Auer.
Marco Wittmann was 17th fastest, ahead of Tom Blomqvist and Timo Glock, whilst ART team mates Esteban Ocon and Gary Paffett would be the lowest placed of the Mercedes drivers in 20th and 21st.
Rene Rast replaces the injured Adrien Tambay for today’s proceedings, as the Frenchman suffered pains in his left hand following the incident with Götz in the opening race.
Rast, who is primarily racing in sportscars, was slowest of all, behind the Team Schnitzer pairing of Martin Tomczyk and António Félix da Costa. However, the German, who is running in the #72 Team Rosberg car this weekend, was just 0.026 seconds off Da Costa’s effort.
Qualifying for the main race at Zandvoort starts at 11:20 CEST, lasting for 20 minutes.
