The pressure on Bird at the front was momentarily relieved when Coletti made a mistake, locked up and ran wide at the end of the penultimate lap which allowed Felipe Nasr to get past him into second place; Coletti seemed to have flat-spotted his tyres in the incident and struggled to stay on track for the remainder of the race, quickly dropping off the back off the fierce battle between Bird and Nasr for the win.
The unleashed Nasr had the raw pace, but Bird had the position - and he made his car as wide as he possibly could to prevent the Carlin from getting past. The two went into the final corners side-by-side but Bird managed to successfully cover the line on the final run down the start/finish straight. That left Nasr inches short (a mere 0.080s in terms of time) at the finish line and Bird was duly able to celebrate taking a maiden win for Russian Time, the team that only entered the GP2 Series in March as a last-gasp replacement for the departing iSport International.
Behind this grandstand finish to the race, Coletti held on to third thanks to the earlier huge gap he'd pulled out on Dillmann. The Frenchman came home a lonely but safe fourth place, doubtless disappointed not to have converted a pole start to a podium especially given the success of his team mate in winning the race.
Calado managed to pass Palmer for fifth in the closing laps, while Abt finished seventh ahead of Quiafe-Hobbs who had finally struggled to the finish in eighth place. That was the last points-scoring position, leaving Fabio Leimer flat out of luck in ninth just ahead of Kevin Ceccon: it means that having got on equal footing with Coletti in the championship after Saturday's feature race, Leimer now drops back down again to second place ten points off the Monagasque's 64 point tally as the GP2 drivers pack up and head out of Sakhir for another year.
