Nico Hulkenberg (right) has taken his first pole position in the main GP2 series with a forceful display of power and finesse in this afternoon's qualifying session in Istanbul, taking the top spot by a tenth from Luca Filippi and Romain Grosjean.

The German bided his time throughout the session before unleashing a lap of 1:34.404, setting all three fastest sectors with just five minutes remaining, and with Vitaly Petrov and Pastor Maldonado stopping on track immediately after with mechanical gremlins there were two yellow flag zones, and the session was effectively over.

With the drivers taking to the track once again in steaming conditions Hulkenberg set an early quick lap before Petrov took the top spot: the Russian driver looked untouchable, but his competitors kept nibbling away at his time, with Lucas di Grassi, Filippi and Karun Chandhok all closing in from behind.

Grosjean finally bested his teammate with six minutes remaining, but Hulkenberg was already on a charge, taking the top spot seconds later with Filippi in tow: Petrov suddenly slowed from a quick looking lap and pulled off to the side of the track, and when Maldonado's car started smoking there was no chance for anyone else to improve their times.

Petrov will nevertheless start from fourth tomorrow, ahead of Chandhok, Andreas Zuber and Alvaro Parente. With a number of drivers caught out of position on the grid, there could well be fireworks when the lights go out in Istanbul tomorrow afternoon.

Note:

Dani Clos has been handed a ten place grid position penalty for failing to heed the marshal's instructions after his spin early in the session, which created an extended yellow flag period.

Giedo van der Garde, Diego Nunes and Edoardo Mortara were all handed three place grid position penalties for failing to sufficiently slow their vehicles in a yellow flag zone.
