Monaco Formula Renault 3.5 race-winner Nico Muller picked up where he left off in the Principality by topping free practice at Spa on Friday.
The Swiss driver, who took his first victory in the category on the streets of Monte Carlo last weekend, jumped to the top of the times for Draco in a dry afternoon session with just three minutes remaining. Until that point, Muller – who was sixth quickest in wet conditions earlier in the day – had not been a factor near the front.
Championship leader Kevin Magnussen led the way for the majority of the session in his DAMS car, losing top spot briefly to Lotus's Marco Sorensen with around 20 minutes to go, and again to Muller at the end. The McLaren junior edged out title rivals Antonio Felix da Costa and Stoffel Vandoorne, both of whom made late improvements to at least get closer to the driver who had a comfortable margin over the field for much of his time out front.
The only other big improvement toward the end of the session came courtesy of Will Stevens. The Briton jumped up to fifth in the closing minutes, before failing to improve on his final lap despite setting a personal best first sector time and the outright best final sector.
Sorensen slumped to sixth after his brief run at the head of the field going into the closing stages, while Oliver Webb, Lucas Foresti, Carlos Sainz Jr and Andre Negrao completed the top 10.
Magnussen had also narrowly missed out on topping the morning session in wet conditions, where he was beaten to first position by local star (and fellow McLaren junior) Vandoorne.
