Times initially began to tumble at the Tempelhof Airport circuit as the abrasive concrete surface around a new 15-turn layout began to clear up on Saturday morning, with Guenther’s 1m02.834s fastest after the opening 10 minutes.
Abt’s Lucas di Grassi soon moved to the top, though, lowering the session best to a 1m02.189s which remarkably stood as the fastest time until the final moments of the session.
