Hughes had been fractionally faster than Fenestraz in the opening sector despite a slide through Sainte Devote, but the Briton initially threw away the chance of pole after cutting the Nouvelle Chicane.
Fenestraz posted a 1m29.131s which would have been enough for the top spot, but he was stripped of his lap time post-session after he was found to have exceeded the 350kW power limit during his final duel attempt.
