The 2015 Bahrain GP2 Series round was a pair of motor races held on 18 and 19 April 2015 at the Bahrain International Circuit in Sakhir, Bahrain as part of the GP2 Series. It was the first round of the 2015 GP2 Series and was run in support of the 2015 Formula One Bahrain Grand Prix. The first race, a 32-lap feature event, was won by ART Grand Prix driver Stoffel Vandoorne who started from the pole position. Rio Haryanto finished second for the Campos Racing team, and Racing Engineering driver Alexander Rossi came third. Haryanto won the second event, a 23-lap sprint race, ahead of Vandoorne in second, and Lazarus driver Nathanaël Berthon in third.

Vandoorne retained his pole position advantage in the first race, which was disrupted on the fourth lap following a collision between Norman Nato, Arthur Pic, Pierre Gasly and Raffaele Marciello. Drivers on the soft-compound tyres made pit stops for medium-compound tyres, while Vandoorne remained the leader for the lap-nine restart. He held it until his pit stop at the end of lap 22, and Rossi moved into the first position on the following lap. He kept the position until Vandoorne overtook him to win the race. Julián Leal started first in the second race and remained the leader until he was passed at the beginning of the eighth lap by Haryanto, who maintained the lead for the rest of the race to clinch the win.

Haryanto's victory in the second race was his first victory in the GP2 Series after 70 races. The results of the races meant Vandoorne assumed the lead in the Drivers' Championship with 50 points, ten in front of Haryanto. Rossi assumed third position, while Berthon's third-place finish in the second event allowed put him in fourth. Jordan King rounded out the top five. ART Grand Prix became the leaders of the Teams' Championship with a 15-point advantage over Racing Engineering. Campos Racing were two points behind in third position, while Lazarus and Rapax rounded out the top five, with ten rounds left in the season.

Report

Background

Bahrain International Circuit, where the race was held.

The 2015 Bahrain GP2 Series' round was the first of eleven scheduled events in 2015. It was held on 18 and 19 April 2015 at the Bahrain International Circuit in Sakhir, and was run in support of the 2015 Formula One Bahrain Grand Prix.[1] The races were contested by twelve teams of two drivers each. The teams were: DAMS, Carlin, ART Grand Prix, Racing Engineering, Russian Time, Trident, Campos Racing, MP Motorsport, Rapax, Arden International, Status Grand Prix, and Lazarus.[2][3] The drag reduction system (DRS) had two activation zones for the race: one was on the start/finish straight linking the final and first corners, and the second on the straight from the tenth and eleventh turns.[4][5] Tyre supplier Pirelli brought two types of tyre to the race: two dry compounds - soft "options" and medium "primes".[6]

The final mass test session before the new season took place at the track over 1–3 April. On the first day, in hot weather conditions, Mitch Evans set the fastest lap of the morning session with a time of 1:42.479, with Jordan King setting the quickest lap of the day in the afternoon session with a 1:41.494.[7] An overnight sandstorm caused the second day's running to be delayed for one hour while circuit officials cleaned the track. Sergey Sirotkin was the fastest driver in the morning session with a lap of 1:41.797, and Nobuharu Matsushita recorded the quickest lap of the afternoon session with a time of 1:40.191.[8] Pierre Gasly recorded the fastest lap time of the three days, a 1:39.632 in the morning session, and Nigel Melker was the quickest driver in the afternoon session with a lap of 1:41.566.[9] Hilmer Motorsport elected to miss the round as they were unable to acquire the services of a driver who could bring financial backing to the team. Team principal Franz Hilmer was confident that he would enter the second round of the season in Catalunya.[10]

Practice and qualifying

Stoffel Vandoorne (pictured in 2013) had his fifth consecutive pole position in the GP2 Series.

One 45-minute practice session was held on Friday before the two races.[5] King was fastest with a time of 1:42.441, ten-hundredths of a second faster than teammate Alexander Rossi in second. Alex Lynn was third-fastest, ahead of Stoffel Vandoorne. Arthur Pic and Rio Haryanto were fifth and sixth. Gasly was seventh-fastest, Evans eighth, Raffaele Marciello ninth, and Matsushita completed the top ten ahead of qualifying. Vandoorne's run ended prematurely with seven minutes of the session remaining when his car stopped due to an oil pressure failure.[11]

Friday afternoon's qualifying session ran for 30-minutes. The drivers' fastest lap times determined the starting order for the first race. The driver who won the pole position was awarded four points that went towards the Drivers' and Teams' Championship races.[5] The session was held in cooler night-time weather conditions. Drivers used soft-compound tyres for their first timed laps before entering the pit lane for new tyres for the remainder of the session.[12] Vandoorne set the pace in the early part of the session and improved to clinch his first pole position of the season, and his fifth consecutive in the series, with a time of 1:39.237.[13][14] He was joined on the grid's front row by his teammate Matsushita who was three-tenths of a second slower than Vandoorne. Lynn was ninth after his first timed lap but recovered to qualify in third place. Pic, who was Vandoorne's closest contender in the session's opening segment, took fourth, ahead of Marciello who was stuck in second gear until his team corrected the issue. King was relegated to sixth by Marciello's fastest lap. Norman Nato and Rossi were seventh and eighth.[14] Gasly made a mistake late in the session which restricted him to ninth and Sirotkin rounded out the top ten.[15] Artem Markelov was the fastest driver to not qualify in the top-ten starting positions; his best lap time was seven-tenths of a second slower than Vandoorne. Haryanto ran strongly in the session's early period but took 12th after he was unable to improve on his second set of soft-compound tyres. He was ahead of Evans, Robert Visoiu, and Richie Stanaway. The two Carlin drivers qualified in 16th and 18th (with Julián Leal ahead of Marco Sørensen). They were separated by Sergio Canamasas in the faster of the two MP Motorsport cars. André Negrão, Daniël de Jong, Nathanaël Berthon, René Binder, Marlon Stöckinger, and Zoël Amberg were the last of the qualifiers.[14]

Races

The first race was held over either 170 kilometres (110 mi) or 60 minutes and all drivers were required to make one pit stop. The first ten finishers scored points, with two being awarded to the competitor who recorded the fastest lap. The starting order for the second event was determined by the finishing positions of the first race with the first eight drivers in reverse order. It was run over either 120 kilometres (75 mi) or 45 minutes and drivers were not allowed to make pit stops. The top eight finishers scored points which counted towards both championships.[5]

Feature race

Alexander Rossi (pictured in 2013) finished in third place.

The first race began at 13:10 Arabia Standard Time (UTC+3) on 18 April.[16] Weather conditions at the start of the race were sunny and hot with an air temperature of 30 °C (86 °F) and a track temperature of 49 °C (120 °F). Windy conditions made the track dusty.[17] When the race started, Vandoorne maintained his pole position advantage heading into the first corner. His teammate Matsushita made a slow start, and his anti-stall system activated allowing several cars to get ahead of him before he got up to speed. Nato made a good start, moving from seventh to third while Lynn inherited second position. Sørensen's car was damaged while fending off an overtaking manoeuvre by de Jong.[18] Rossi overtook his teammate King to move into seventh place on the same lap and started to close the gap with Pic and Gasly.[17] Sørensen drove into the pit lane to retire because of the damage sustained from de Jong's passing manoeuvre.[18]

Marciello employed the DRS on the fourth lap to close to Nato heading into the first turn while battling him for fourth place. As the two drivers battled through turn four, Pic got ahead of them.[19] Nato changed his line by braking for the seventh corner, and Marciello made an aggressive passing manoeuvre, causing both drivers to make contact with Pic, sending him spinning backwards. Gasly arrived at the apex of the turn and was collected by Pic who also drove into Marciello.[18][19] Pic, Gasly and Marciello retired immediately and the safety car was deployed.[19] Drivers who had started on the soft-compound tyres elected to change to the medium-compound tyres during their mandatory pit stops, which meant they rejoined the race outside of the top ten. These drivers had to hope that the medium-compound tyres would last until the end of the race while pushing hard.[18] Marciello drove back to the pit lane and retired. King was forced to wait behind Rossi during the pit stop phase and fell to 17th.[19]

Vandoorne remained with his intended strategy and led the field back up to speed at the lap-nine restart, ahead of Haryanto and Leal. He fended off an attempted overtake by Haryanto heading into the first corner, while Leal fell to fifth after he was passed by Matsushita and Visoiu.[18] While in traffic, Lynn attempted to pass Rossi heading into the first turn, but made contact with the rear-end of his car and sustained front wing damage.[2] Rossi pushed hard and moved ahead of Amberg by the twelfth lap. He caught up to Stanaway and quickly overtook him, and passed Berthon with the use of DRS two laps later.[17] Rossi made further use of the system to get ahead of de Jong and Markelov. It allowed him to build a large gap to Lynn who was struggling.[18] Rossi overtook Leal to move into fifth on lap 15,[17] and the drivers who were running in the middle of the field made their mandatory tyre pit stops. Evans overtook Lynn driving into turn one on the 18th lap. Lynn reported that his car had tyre degradation problems and dropped down the running order, while cars who conserved their tyres took advantage.[18]

Matsushita made a pit stop at the end of lap 20 which promoted Rossi into fourth place. Rossi was approximately ten seconds behind Vandoorne which meant the Belgian driver would be unable to remain the leader after making his pit stop.[18] Vandoorne made his pit stop at the end of the 22nd lap,[2] and he was delayed while his pit crew installed his right-front tyre which cost him time.[18] He reemerged in tenth place.[19] The rest of the leaders made their pit stops allowing Rossi to move into first place on lap 23.[18][17] Rossi was 6.7 seconds ahead of second-placed Evans who was battling with King.[19] The Racing Engineering driver overtook Evans for second on lap 25, although the New Zealander used DRS to reclaim the position.[17] Vandoorne was more than 20 seconds behind the race leader, but his new, soft-compound tyres allowed him to record lap times that were five seconds faster than Rossi.[19] The battle between Evans and King allowed Rossi to pull away and created an obstruction giving Vandoorne an advantage which he took.[18] He passed King with DRS to claim third on lap 28,[17] and got ahead of Evans shortly afterwards.[18] Rossi held a nine-second lead over Vandoorne with four laps remaining with the Belgian driver lapping three seconds faster in clean air.[19]

Rossi struggled with severe tyre degradation and increasingly locked and flat-spotted his tyres.[18] Vandoorne had reduced Rossi's lead by the penultimate lap. He chose not to rush to avoid damaging his car. He moved into the lead after leaving the back straight when Rossi ran wide at the first hairpin.[18][19][2] Haryanto made a similar strategy call as Vandoorne and passed King and Rossi to move into second position.[18][19] Vandoorne maintained the lead for the remainder of the race and crossed the start/finish line after 32 laps to win the race. Haryanto finished second, with Rossi in third. King took fourth, ahead of Visoiu and Evans. Berthon, Leal, Negrão, and Matsushita rounded out the top-ten finishers.[2] Eleventh-place finisher Stöckinger became the first driver from the Philippines to complete a GP2 Series race.[18] He was ahead of Sirotkin, Markelov, Canamasas, and Stanaway. Amberg, Binder, de Jong and Lynn were the last of the classified finishers.[2]

Sprint race

Rio Haryanto (pictured in 2011) clinched the first GP2 Series victory of his career.

The second event started at 14:10 local time on 19 April.[16] Sirotkin was required to start from the pit lane after stalling his car at the beginning of the formation lap. When the race started, pole position starter Leal maintained his advantage heading into the first corner by driving aggressively in front of the field of cars.[20] Haryanto made a good start, moving from seventh to third by running on the outside line,[21] while Berthon made a slow getaway and dropped to seventh.[20] King lost the most positions, moving from fifth to 13th, which he attributed to driving conservatively on the formation lap, and having no grip while moving off his starting position.[22] Leal pulled out to the lead over the rest of the field by pushing hard.[20][3] After completing two laps, Binder retired from the race, having made contact with another car, which damaged one of his front left suspension arms.[23] Evans was overtaken by Haryanto for second place in the first turn on lap four,[3] while Negrão lost position when he was passed by Visoiu, Matsushita, Vandoorne, and Rossi.[20]

King made contact with Canamasas in the fourth corner while driving alongside him during lap four. Both went off the circuit, with Canamasas sustaining front wing damage, which stopped his car. He became the race's second (and final) retirement. King continued but rejoined in 12th. Leal's pace had slowed due to tyre degradation.[20][3] This allowed Haryanto to close up to Leal who passed him by deploying DRS to move into the lead around the inside on lap eight in turn one.[20][21][3] Evans attempted to move in front of Leal but ran wide, allowing the latter to retake the second position. Visoiu took advantage and overtook Leal for second place.[20] Evans again drove aggressively but Leal was defensive and his front wing endplate glanced Evans' front-left tyre at the turn eight hairpin. Evans drove to the pit lane for replacement tyres. Leal remained on the track, but was overtaken by Visoiu for second at the first corner on lap 10.[20][3] Rossi moved ahead of Leal for sixth place, while King recovered to run in ninth position.[20]

Haryanto held a three-second advantage over Visoiu who had worn his tyres, and he was unable to maintain the pace. Matsushita overtook Visoiu as a result.[20] Vandoorne was overtaken Visoiu on the pit lane straight with the assistance of DRS at the start of the 16th lap.[20][3] Vandoorne began to push hard and lapped one second faster than his teammate Matsushita. He was able to move in front of Matsushita for second place after starting lap 18, providing him with an opportunity to attempt to catch Haryanto during the remainder of the event. Haryanto responded and pulled away from Vandoorne. His teammate Matsushita struggled with pace and was passed by Rossi for third place.[20] Berthon recovered from his poor start and moved ahead of Rossi, with the assistance of DRS, at the start of the final lap. Haryanto crossed the start/finish line after 23 laps to win his first GP2 Series race in his 70th attempt.[3] Vandoorne finished second, ahead of third-placed Berthon. Rossi secured fourth, with Leal fifth. Matsushita, Visoiu, and Negrão rounded out the points-scoring positions. King, Pic, Stanaway, Markelov, de Jong, and Sirotkin filled the next five positions, while Lynn, Nato, Evans, Amberg, Stöckinger, Marciello, Sørensen, and Gasly were the last of the classified finishers.[3]

Post-race

The top three drivers of both races appeared on the podium to collect their trophies and to participate later in a press conference. After the feature race, Vandoorne said that it was a "very entertaining race" and he thought that the safety car came out at the wrong time. He stated that from his point of view overtaking was easy, and he did not expect to catch Rossi, but it had been a good start for the season starting from first place, recording the fastest lap, and winning the event.[24] Haryanto said it felt "really great" to finish on the podium, but thought it would be difficult to close the gap with the drivers in front of him. He stated that he did not expect to have a fast pace on the soft-compound tyres but knew that his pace under race conditions was good.[24] Having been disappointed at his result in the qualifying session, Rossi was pleased to stand on the podium. He felt he achieved the best result for Racing Engineering. He stated that it was a good race for the team, and felt he should have not pushed too hard when he knew Vandoorne was in clean air.[24]

When the sprint race had finished, Haryanto said his first victory had been "a long time coming", and that the event was a "perfect race". He said he expected to score points and finish on the podium at the next round in Catalunya, because the events at Bahrain increased his confidence and helped him to believe he would achieve more success.[25] Vandoorne stated that the second race was also interesting, and was happy with his results. He said that his team had observed lap times from the previous race and knew that he would be strong in the second event. Vandoorne stated that and was looking forward to Catalunya and had to maintain his momentum and demonstrate the team is "capable of winning there as well".[25] Berthon said that his third-place finish was "simply amazing" for his team and himself, and his position in the Drivers' Championship was "incredible". He revealed that his team felt "different" and was working hard to give him the best possible car. All they were missing was "some pace".[25] Canamasas was judged by the stewards to have left insufficient room in the collision between himself and King and was issued with a three-place grid penalty for the next round in Catalunya.[26]

Following this, the first race of the season, Vandoorne led the Drivers' Championship with 43 points, ten ahead of second-placed Haryanto. Rossi was in third on 23 points, with Berthon in fourth. King rounded out the top five with 12 points.[27] ART Grand Prix assumed the lead of the Teams' Championship with 50 points; Racing Engineering and Campos Racing were close behind in the battle for second place with 35 and 33 points. Lazarus was fourth on 16 points, four in front of Rapax in fifth place, with ten races left in the season.[28]
