Louis Deletraz ended the final day of 2016 pre-season Formula V8 3.5 testing on top at Aragon on Sunday
Driving for defending champion team Fortec Motorsports, the Formula Renault 2.0 NEC title-winner set his fastest lap of 1m40.235s in the morning session, to finish 0.111 seconds ahead of Arden's Saturday pacesetter Egor Orudzhev.
Last year's FR3.5 runner-up Matthieu Vaxiviere took third on another solid outing for newcomer SMP Racing.
Deletraz's Fortec stable-mate Pietro Fittipaldi was fourth, from AVF runner Tom Dillmann and the second Arden entry of Aurelien Panis.
Roy Nissany in the Charouz-run Lotus entry was the only competitor to set his fastest lap in the afternoon session.
The Israeli finished Sunday eighth fastest, sandwiched between Teo Martin Motorsport's pairing of Yu Kanamaru, in seventh, and Beitske Visser.
