Pal Varhaug remained on top on the final afternoon of GP3 pre-season testing in Barcelona.
With drivers concentrating on long runs, Varhaug was able to set the fastest time again despite being more than two and a half seconds slower than he had been during the morning.
Arden drivers Kevin Ceccon and Emil Bernstorff were closest to his pace, ahead of ART’s Marvin Kirchhofer. Varhaug’s Jenzer team-mate Ralph Boschung was fifth ahead of Koiranen’s Adderly Fong, Campos racer Alex Palou and European F3 champion Esteban Ocon (ART).
Matt Parry and Alex Bosak completed the top ten for Koiranen and Arden respectively.
The GP3 season begins at the same circuit in Barcelona in just over two weeks’ time, on 8-10 May.
