Emanuele Smurra was quickest in 1:39.036 (set on lap 14) as he edged out Paolo Necchi (1:39.129). Another second spot for Necchi was proof of how at home he feels on this circuit. Bettering his time and placing from the morning was Pietro Zumerle (1:39.183) who came home third.
Heyrowsky got off to a strong start but could not match this morning's consistency and slipped to eighth behind Goldstein/Sundberg (fifth in 1:39.435), Sergio Rota (1:39.605), who ran into the sand at turn 7 right at the end of the session, and Enrico Moncada (1:39.665).
There was not much that separated the drivers in the forty minute stint with the fastest runners bunched less than a second apart.
The two German journalists, Naumann and Gebhardt, are on row five, with Francesco La Mazza and Mariano Bellin tucked in behind them. Thirteenth is Andreas Segler with Herpell in fourteenth as he makes his debut in the 2010 Maserati championship.
On row eight is Tiziano Frazza and Ladas, from Greece. Bringing up the rear is the Santamaria/Schaper crew and Swiss driver Pawlicek.
