The first race was held over or 60 minutes (whichever came first) and the regulations required drivers to make one
pit stop. The first ten finishers scored points, with two given to the
fastest lap holder. The grid for the second race was determined by the finishing order of the first but with the first eight drivers in reverse order of where they finished. It was run for or 45 minutes (whichever came first). In contrast to the prior race drivers were not required to make pit stops. The top eight finishers earned points towards their respective championships.
Feature race (pictured in 2015) was caught up in a first lap accident triggered by
Johnny Cecotto Jr. The feature race was due to start at 11:15
Central European Summer Time (
UTC+02:00) on 24 May, Repairs were required to the barriers at the turn as they had been dislodged, and oil laid on the track surface at the same turn was covered with cement dust.
wheelspin from Cecotto allowed his teammate Evans to lead the field into Sainte Dévote turn. Soon after a 15-car crashed at the first corner forced a
stoppage. After losing the lead Cecotto was holding off Leimer through Sainte Dévote, it became impossible for Cecotto to maintain his line and he
understeered straight into the barrier. Leimer was trapped and mounted the left-hand corner of Cecotto's car. Palmer took avoiding action by spinning on the inside, blocking the turn. Palmer avoided injury when Leal's front wing almost struck his helmet. Coletti, Leal, Dillmann, Frijns, Ericsson, Rossi, Berthon, Binder, Giovesi, Haryanto, Rosenzweig and Abt were all trapped in the blockade with varying degrees of car damage. It was Bird's third GP2 Series win, After the race, the stewards deemed Cecotto responsible for causing the first lap stoppage and barred him from competing in the following day's sprint race. Most cars started on the soft compound tyres. Calado initially held third, Nasr passed Calado at the start of the following lap at Sainte Dévote corner for fourth position. Coletti pressured him by using his local knowledge to apply pressure on the latter. Coletti lined up an overtake on Quaife-Hobbs on the third lap leaving the tunnel and into the Novelle Chicane. He steered right onto the inside and braked later than Quaife-Hobbs to pass him for the lead. Coletti began to pull away from Quaife-Hobbs, setting the race's fastest lap at that point on the fourth lap to be 2.1 seconds ahead.
(pictured in 2010) became the first Monegasque driver to win a race in Monaco since
Louis Chiron in 1931. Quaife-Hobbs focused himself on holding off the closing Evans, Nasr and Calado. Dillmann was forced to go two laps behind the leader on the seventh lap after he sustained car damage. Bird in seventh was challenged by Ceccon entering the Novelle Chicane forcing Bird to overshoot the corner to avoid a collision. Bird was aware that his move would entail a drive-through penalty and yielded seventh to Ceccon. Richelmi immediately attacked Bird but it became evident that Bird's car had a major problem. Bird lost further positions before entering the pit lane for technical assistance that put him one lap behind the race leader. He thus set the race's fastest lap on supersoft tyres; as he was outside the top ten he did not score the point entailed by the achievement. Palmer overtook Canamasas on lap 13 in a near-identical move to Abt's pass on Haryanto in the previous day's race. But on this occasion, both drivers continued without significant damage. Quaife-Hobbs held off the three-car train and appeared stronger as the race progressed and the tyres degraded. As the field became tightly packed, no driver had the advantage of getting the edge for moving up the field. This was the case until Rosenzweig stuck the front of his car down the inside of Lancaster through the Lowe's
hairpin and tapped him into a half-spin. Rosenzweig moved into tenth as Lancaster could not recover sufficiently from the incident and lost five places in two corners. Coletti's hold on first waned because tyre degradation removed some of his earlier speed and handling, lowering his lead over Quaife-Hobbs to a second. Less than four seconds covered the first five with a 14-second gap over a battle for sixth between Binder, Ceccon and Richelmi. Coletti had help from Quaife-Hobbs who defended from Evans. By this point, the track was completely dry with no rainfall. Evans tried again to take second on the final lap, almost hitting the rear of Quaife-Hobbs's car as the pair left the Novelle Chicane. Coletti maintained the lead for the rest of the race to win, making him the first Monegasque driver to win on the streets of Monaco since
Louis Chiron in the
1931 Monaco Grand Prix. Quaife-Hobbs finished in second position, three-tenths of a second ahead of Evans in third. Nasr, Calado, Binder, Ceccon and Richelmi made up positions four through ten. De Jong, Rosenzweig, Canamasas, Palmer, Leimer, Leal, Frijns, Haryanto, Lancaster, Ericcson, Rossi, Giovesi, Berthon, Abt, Trummer, Bird and Dillmann were the final classified finishers.
