The trio of Italian Luca Ghiotto, Frenchman Esteban Ocon and Spaniard Palou were the closest chasers of Kirchhofer, finishing in second, third and fourth respectively and withint two tenths of the German.
Kevin Korjus was the fastest Koiranen driver as he stands in for Adderly Fong for this test, followed by Pal Varhaug and Emil Bernstorff.
Trident’s Oscar Tunjo was eighth fastest and the top ten was rounded out by Koiranen pairing Matt Parry and Jimmy Eriksson.
