Sims, Mortara lead Masters practice
Alexander Sims and Edoardo Mortara were fastest in the two morning practice sessions for the Formula 3 Masters at Zandvoort
The F3 Euro Series rivals topped a session apiece, with ART driver Sims' 1m32.683s from the opening test the quickest time of the morning.
Mortara (Signature) was 0.257 seconds down on Sims in that session, but set the pace later on, beating Prema's Daniel Juncadella to the practice two top spot by just 0.008s.
Marco Wittmann was third in another Signature entry in both sessions.
GP3 frontrunner Nigel Melker, making his F3 debut with Mucke this weekend, was an impressive sixth in the first session but caused a red flag when he crashed heavily at the Hunserug corner in the second. The damage to his car was severe enough to threaten his participation in qualifying.
Last year's Masters winner Valterri Bottas spun his ART Dallara-Mercedes into the gravel halfway through the second session, but his best time still kept him fifth.
The Euro Series teams have dominated so far, with the top British championship runner in session one being Carlin's Rupert Svendsen-Cook in 10th, while his points-leading team-mate Jean-Eric Vergne led the British contingent back in 12th in the second session.
