That left Palmer with a massive 10s lead at the top of the timesheets ahead of Chilton, with van der Garde picking up third place ahead of iSport's Marcus Ericsson, van der Garde's Caterham team mate Rodolfo Gonzalez in fifth. Arden's Luiz Razia was one of the biggest beneficiaries of the opening lap chaos and was now up in sixth place with an excellent chance to make up some of the lost ground over the championship leader Valsecchi in the points standings.
With Julian Leal also pulling off the track and exiting the race on lap 12, fully half of the field had been eliminated from the race before the midway point. Inevitably, the thinning of the field combined with Palmer's huge lead made the rest of the race rather an anti-climax and something of a procession as everyone sought to simply make it to the end without further incidents. Chilton did his best to make a show of it now he didn't have the ailing Calado in the way: he was able to more than halve Palmer's huge lead, but then the iSport driver was hardly feeling under any pressure to push hard in response.
In the end, Palmer's margin of victory was down to just one second, but even so he had never been under any genuine pressure since the restart. Not only was it Palmer's first GP2 win, it was his first series podium and he was joined for his inaugural GP2 trophy presentation and champagne celebrations by Chilton and van der Garde.
Luiz Razia had not been able to make any further progress on sixth place, but he did ensure that he snatched up the extra points for fastest lap on the final circulation of the day.
Despite rejoining the race with a new front wing and going on to set some fastest sector times, Calado's streak of race finishes came to an end when he retired in the pit lane on lap 20. He was the last of the cars to exit the race, leaving just 12 cars to complete the race out of the starting grid of 26.
