Vitaly Petrov has continued his Barwa Addax team's outstanding form this season by dominating today's first race in Istanbul, brushing off the scorching conditions to claim victory by 6.5 seconds from Luca Filippi and Davide Valsecchi.

The win was set up on the second lap when Filippi bravely threw his car inside race leader Nico Hülkenberg at the final corner: the pair narrowly avoided touching but both slid wide, giving Petrov a narrow but clear line through and into the lead by the end of the front straight, with the Italian slotting in behind him.

The front two made their excuses and left the rest of the field to their madness, with cars overtaking each other constantly up and down the remainder of the field who were running side by side throughout the race. Andreas Zuber looked to be the only other driver to be able to escape the melee when he slid past Hülkenberg, handing the German a large problem in the shape of Alvaro Parente.

Ultimately the Portuguese driver pushed too hard, spinning into retirement at turn 8 and prompting a safety car period just after Filippi and Zuber had narrowly avoided each other as they escaped from the pits: Petrov was given a free pass in the pits and held on to the top spot ahead of the pair as he set about rebuilding his lead once again.

Behind him the second half of the race was less enjoyable for Zuber, who dropped like a stone over the last laps to fall out of the points: with Filippi holding on for a strong second place, Valsecchi took advantage of a safety car pitstop to leapfrog from tenth on the grid to push his countryman all the way to the flag for third, while Alberto Valerio drove a mature race to slot into fourth place, one ahead of a disappointed Hülkenberg, while Pastor Maldonado, Giedo van der Garde and Javier Villa rounded out the points.

Petrov's win, along with his fastest lap, was enough to propel the Russian to second place in the championship table with 29 points, just two behind his championship leading teammate Romain Grosjean who retired from today's race, while Jerome d'Ambrosio clings on to third on 18 points ahead of Maldonado, Hülkenberg and Filippi.

Note:

The stewards of the race meeting have handed down the results of their investigations into incidents during this afternoon's race in Istanbul, following discussions with all involved parties immediately after the event.

Championship leader Romain Grosjean was handed a 10 grid place penalty for race two tomorrow after he was judged to have overtaken the safety car when leaving the pitlane: he was not qualified in race one after failing to finish the event.

Giedo van der Garde also overtook the safety car when leaving the pitlane, and has 25 seconds added to his elapsed time for race one and a 10 grid penalty for race two. This promotes Javier Villa to seventh place, with Lucas di Grassi taking the point for eighth place and tomorrow's reverse pole.

In addition, Nico Hulkenberg was given a reprimand as a result of his off-track excursion shortly after the restart when he ran wide at turn 8: the German was judged to have rejoined the track without due care and attention, and almost caused a collision with a following competitor.
