FIA Formula Two Championship runner-up Christopher Zanella recorded the fastest time on the second and final day of testing at the Circuit de Catalunya.
The Swiss driver set the pace in the opening of the day's four sessions, with a best time that would remain unbeaten for the remainder of the day – just.
German F3 driver Markus Pommer came close with the best time in the fourth and final session, missing out on Zanella's benchmark by a narrow 0.014 seconds.
2011 race winner Mihai Marinescu ended up third fastest with his time from the first session, ahead of European F3 Open champion Alex Fontana. Italian F3 graduate Edoardo Liberati completed the top five.
German driver Riccardo Brutschin was next up, just ahead of Formula Renault 3.5 regular Daniel McKenzie and Dutch F2 regular Kelvin Snoeks. Italian GP3 pilot Vittorio Ghirelli was ninth, with debutant Matheo Tuscher completing the top ten. The 15-year-old Frenchman – who this year won the Formula Pilota series in China – posted the quickest time of anyone in the day's third session.
James Cole replaced yesterday's pacesetter Miki Monras in the no. 2 car and was 11th fastest, ahead of fellow Brits Formula Ford champion Scott Malvern and Formula Renault BARC driver Hector Hurst.
Max Snegirev was 14th, ahead of Swiss Formula Renault graduate Mauro Calamia, Croatian Sascha Radola and Sandro Zeller. Brit Alex Craven was bottom of the pile, as he was yesterday.
