GP2 Series championship leader Stoffel Vandoorne was quickest in practice at Spa-Francorchamps, leading Mitch Evans and Alexander Rossi.
ART Grand Prix driver Vandoorne, racing in front of his home fans in Belgium this weekend, set a time of 1m57.499s early in the session to take top spot, and then improved that to a 1m57.486s to confirm his place at the head of the field.
Evans was second for Russian Time, 0.154s back from Vandoorne, with Rossi third for Racing Engineering ahead of DAMS driver Alex Lynn.
Current Formula Renault 3.5 Series leader Oliver Rowland was an impressive fifth on his second appearance for MP Motorsport, but stopped on track late in the session at the Bus Stop Chicane.
Pierre Gasly was sixth in the second DAMS machine ahead of Sergey Sirotkin of Rapax, while Arthur Pic was eighth for Campos Racing despite losing his front wing after colliding with the barrier on the run down to Pouhon.
Jordan King was ninth in the second Racing Engineering entry, while Raffaele Marciello completed the top ten for Trident despite having a close encounter with one of the Status Grand Prix drivers after the Italian was forced to stop at the end of the pit lane.
A further incident for debutant Gustav Malja brought out more yellow flags when the Swedish driver, racing this weekend at Trident in place of an unwell Rene Binder, lost the back end of his car and was left stranded at the Bus Stop Chicane.
