Singapore GP2: Jolyon Palmer fastest in free practice

The daylight session, the conditions in which both of the Marina Bay races will also be held, was dominated by the Carlin driver.

Palmer's first effort was a 1m56.602s, which he lowered to a 1m55.912s after a cool-off lap.

Palmer's fastest time was 3.532s quicker than last year's pole time, set by Luca Filippi, thanks to the removal of the chicane at Turn 10. All cars ran on the soft prime compound, teams saving the supersoft options for qualifying.

Championship leader Fabio Leimer was second fastest for Racing Engineering, although many of his early attempts were thwarted by traffic. Marcus Ericsson was quick throughout the session and ended up third for DAMS, ahead of Alexander Rossi's Caterham machine.

Mitch Evans was one of the few drivers to improve in the second half of the session, rising to fifth in his Arden machine. British duo James Calado and Sam Bird were sixth and seventh respectively, with Felipe Nasr eighth ahead of Johnny Cecotto Jr.

Former series leader Stefano Coletti suffered another dreadful time, slumping to 24th and clearly struggling with poor handling as he overshot a corner and was forced into a three-point turn.

Elsewhere, Jake Rosenzweig clattered a wall, Dani Clos clipped one and even session dominator Palmer had a huge slide in the closing stages, which he collected up without hitting anything.
