GP2 champion-in-waiting Romain Grosjean was again in a league of his own in free practice at Spa-Francorchamps. The Frenchman, who will win the title this weekend if he maintains his current advantage in the points, was nearly eight tenths of a second quicker than anyone else in changing conditions.

The session began on a damp track, though the drivers were able to take to the track on slick Pirelli tyres. The session was soon halted however when Jolyon Palmer crashed at La Source, bringing out the red flags. Once the session was restarted Johnny Cecotto Jr. was the early pacesetter, but Grosjean soon moved into first place.

With forecasts of more rain later in the session, the field spent the middle of the session in the pits waiting to see which tyres to fit for the closing stages. The rain did intensify, forcing the drivers to use wet tyres.

This meant that Grosjean's time went unbeaten. Belgian-Romanian Michael Herck was second fastest, just one thousandth of a second ahead of Marcus Ericsson. Grosjean's nearest rivals in the points, the Addax duo of Giedo van der Garde and Charles Pic, were next up in fourth and fifth.

Luiz Razia was sixth, ahead of Max Chilton, Christian Vietoris, Jules Bianchi and Dani Clos. Brendon Hartley, who has rejoined the series in place of Kevin Mirocha at Ocean, was 24th.
