2015 Abu Dhabi Grand Prix

Going into the race weekend, both Championships were already decided. Lewis Hamilton had already secured the drivers' title three races earlier at the 2015 United States Grand Prix and was leading the Drivers' Championship with 363 points, 66 points ahead of his teammate Nico Rosberg.{{cite web|title=2015 Driver Standings|url=http://www.formula1.com/content/fom-website/en/championship/results/2015-driver-standings.html|website=formula1.com|access-date=22 November 2015|archive-url=https://web.archive.org/web/20151122141403/http://www.formula1.com/content/fom-website/en/championship/results/2015-driver-standings.html|archive-date=22 November 2015}} In the Constructors' Championship, their team Mercedes had also secured the constructors' title four races earlier at the 2015 Russian Grand Prix and was leading Ferrari on 660 to 401 points.{{cite web|title=2015 Constructor Standings|url=http://www.formula1.com/content/fom-website/en/championship/results/2015-constructor-standings.html|website=formula1.com|access-date=22 November 2015|archive-url=https://web.archive.org/web/20151122141100/http://www.formula1.com/content/fom-website/en/championship/results/2015-constructor-standings.html|archive-date=22 November 2015}} However, several positions in the standings were still undecided. In the battle for fourth place in the Drivers' Championship, Valtteri Bottas was just one point ahead of compatriot Kimi Räikkönen, with Felipe Massa in sixth also still able to get the position, being 19 points behind his Williams teammate Bottas. Red Bull teammates Daniil Kvyat and Daniel Ricciardo were just ten points apart in the battle for seventh in the championship. In the Constructors' standings, sixth placed Lotus was just nine points ahead of Toro Rosso, while McLaren needed at least nine points as well to overcome Sauber for eighth, a points tally they had only managed once during the rest of the season.{{cite web|last1=Collantine|first1=Keith|title=A dozen battles to watch in the final race of 2015|url=http://www.f1fanatic.co.uk/2015/11/25/a-dozen-battles-to-watch-in-the-final-race-of-2015/|publisher=F1Fanatic|access-date=29 November 2015|archive-url=https://web.archive.org/web/20151129115755/http://www.f1fanatic.co.uk/2015/11/25/a-dozen-battles-to-watch-in-the-final-race-of-2015/|archive-date=29 November 2015|date=25 November 2015}}

Per the regulations for the 2015 season, three practice sessions were scheduled, two 1.5-hour sessions on Friday and another one-hour session before qualifying on Saturday.{{cite web|title=Practice and qualifying|url=http://www.formula1.com/content/fom-website/en/championship/inside-f1/rules-regs/Practice_qualifying_and_race_start_procedure.html|website=formula1.com|publisher=FOM|access-date=25 October 2015|archive-url=https://web.archive.org/web/20150905082403/http://www.formula1.com/content/fom-website/en/championship/inside-f1/rules-regs/Practice_qualifying_and_race_start_procedure.html|archive-date=5 September 2015}} Lewis Hamilton was fastest in the first free practice session, run in clear and sunny conditions, lapping in a time of 1m43.754s, over one-tenth of a second faster than teammate Rosberg in second. Rosberg had set new fastest sector times on his last fast run, but a mistake in the last part of the track lost him a chance at the best time. Kimi Räikkönen was third fastest for Ferrari, ahead of Daniil Kvyat. Kvyat's Red Bull teammate Ricciardo changed back to his older specification Renault power unit, after being unsatisfied with the performance of his updated unit at the previous race in Brazil.{{cite web|last1=Barretto|first1=Lawrence|title=Upgraded Renault F1 power unit no better, says Red Bull's Ricciardo|url=http://www.autosport.com/news/report.php/id/121805|publisher=autosport.com|work=Autosport|access-date=15 November 2015|archive-url=https://web.archive.org/web/20151114235936/http://www.autosport.com/news/report.php/id/121805|archive-date=14 November 2015|date=14 November 2015}} He finished the session seventh fastest.

In the second session of Friday afternoon, Nico Rosberg topped the timesheets, setting a time of 1m41.983s, finishing more than a tenth of a second ahead of Hamilton. Third fastest was Sergio Pérez for Force India, although he was unable to run in the last twenty minutes of the session due to brake issues. The Red Bull drivers Kvyat and Ricciardo were fourth and sixth respectively, while Fernando Alonso came within one second of Rosberg's time in ninth.{{cite web|last1=Parkes|first1=Ian|title=Abu Dhabi GP: Nico Rosberg leads Lewis Hamilton in F1 practice two|url=http://www.autosport.com/news/report.php/id/122013|website=autosport.com|access-date=29 November 2015 |archive-url=https://web.archive.org/web/20151129120900/http://www.autosport.com/news/report.php/id/122013 |archive-date=29 November 2015 |date=27 November 2015}}

Rosberg was again fastest in the third session on Saturday with a time of 1m41.856s. Hamilton was second quickest, almost three-tenths of a second slower, unable to get a clean lap to match his teammate. On the slower soft tyres, one lap was impeded by traffic, another was disturbed by Hamilton spinning after hitting the kerb at turn five. He again failed in his attempt on a very fast lap on the super-soft tyres later in the session, being forced wide after repeating his mistake at turn five. Hamilton was just marginally ahead of Sebastian Vettel, who finished third ahead of Pérez. Daniil Kvyat was unable to set a timed lap as his team worked to solve an electrical problem.{{cite web|last1=Barretto|first1=Lawrence|title=F1 Abu Dhabi GP: Mercedes' Rosberg stays on top in final practice|url=http://www.autosport.com/news/report.php/id/122031|website=autosport.com|access-date=29 November 2015|archive-url=https://web.archive.org/web/20151129120910/http://www.autosport.com/news/report.php/id/122031|archive-date=29 November 2015|date=28 November 2015}}

Qualifying consisted of three parts, 18, 15 and 12 minutes in length respectively, with five drivers eliminated from competing after each of the first two sessions. At the beginning of the first part of qualifying (Q1), Mercedes sent both their drivers out on the faster super-soft compound, while Ferrari stayed on the slower soft tyres.{{cite web|title=Nico Rosberg takes his sixth straight pole position at the Abu Dhabi GP|url=http://www.skysports.com/f1/news/12433/10082066/nico-rosberg-takes-his-sixth-straight-pole-position-at-the-abu-dhabi-gp|publisher=Sky Sports|access-date=2 December 2015|archive-url=https://web.archive.org/web/20151202180354/http://www.skysports.com/f1/news/12433/10082066/nico-rosberg-takes-his-sixth-straight-pole-position-at-the-abu-dhabi-gp|archive-date=2 December 2015|date=28 November 2015}} Even though Ferrari eventually decided to give both their drivers out on the faster tyres towards the end of the session, Sebastian Vettel aborted his last flying lap, believing his time to be sufficient for proceeding into the next round, only for Jenson Button to set a time to relegate Vettel into 16th place on the grid, eliminating him from qualifying.{{cite web|last1=Collantine|first1=Keith|title=Rosberg makes it six poles in a row despite old engine|url=http://www.f1fanatic.co.uk/2015/11/28/rosberg-makes-it-six-poles-in-a-row-despite-old-engine/|publisher=F1Fanatic|access-date=2 December 2015|archive-url=https://web.archive.org/web/20151202180348/http://www.f1fanatic.co.uk/2015/11/28/rosberg-makes-it-six-poles-in-a-row-despite-old-engine/|archive-date=2 December 2015|date=28 November 2015}} Vettel would later describe his and the team's judgement as "a small mistake with a big consequence".{{cite web|last1=Barretto|first1=Lawrence|last2=Freeman|first2=Glenn|title='Small mistake' in Abu Dhabi GP qualifying was costly for Vettel|url=http://www.autosport.com/news/report.php/id/122037|website=autosport.com|access-date=2 December 2015|date=28 November 2015|archive-url=https://web.archive.org/web/20151202181628/http://www.autosport.com/news/report.php/id/122037|archive-date=2 December 2015}} Fernando Alonso in the other McLaren did not make the cut, after a puncture on his last lap left him without a chance at a faster time, while Marcus Ericsson was held up by a technical issue, qualifying 18th. Both Manor Marussia drivers were eliminated at the bottom of the standings, with Will Stevens 1.137 seconds ahead of his teammate Roberto Merhi.{{cite web|last1=Anderson|first1=Ben|title=Nico Rosberg takes sixth straight F1 pole in Abu Dhabi GP qualifying|url=http://www.autosport.com/news/report.php/id/122034|website=autosport.com|access-date=2 December 2015|archive-url=https://web.archive.org/web/20151202180344/http://www.autosport.com/news/report.php/id/122034|archive-date=2 December 2015|date=28 November 2015}}

Lewis Hamilton was fastest in Q2, two-tenths of a second ahead of his teammate Rosberg. In his last qualifying session with Lotus, Romain Grosjean experienced technical difficulties that forced him to come back into the pits. Even though he was sent out again, he was unable to set a time, stopping his car at turn seven. His teammate Pastor Maldonado also did not proceed into Q3, as did Jenson Button who missed out by two-tenths of a second. The two other drivers eliminated were Felipe Nasr for Sauber and Max Verstappen, who was unable to match the time of his teammate Carlos Sainz Jr.

The top ten drivers competed for pole position in Q3 and it was a battle between the two Mercedes. Lewis Hamilton set his fastest time first with Rosberg right behind him. A much better time in the third sector of the track allowed Rosberg to take his sixth consecutive pole position almost four-tenths ahead of his teammate. Sergio Pérez held third spot for much of the session but was beaten to it by Kimi Räikkönen during the second turn of runs. The two were followed by Daniel Ricciardo and Valtteri Bottas on the third row of the grid. Following a gearbox change after qualifying, Romain Grosjean was demoted five places on the grid. Roberto Merhi and Will Stevens also received five place penalties: Stevens for a change of the Control Electronics unit, Merhi for changes made to his suspension. Both would start the race from the back row of the grid.{{cite web|title=Five-place gearbox penalty for Grosjean|url=https://www.formula1.com/content/fom-website/en/latest/headlines/2015/11/five-place-gearbox-penalty-for-grosjean.html|website=formula1.com|access-date=2 December 2015|archive-url=https://web.archive.org/web/20151202184557/https://www.formula1.com/content/fom-website/en/latest/headlines/2015/11/five-place-gearbox-penalty-for-grosjean.html|archive-date=2 December 2015|date=29 November 2015}}

At the start of the race on Sunday, Hamilton got away slowly but was able to keep both Pérez and Räikkönen behind him while Rosberg retained the lead. Further back, Fernando Alonso made contact with Felipe Nasr and then crashed into Pastor Maldonado, who was forced to retire. Alonso needed to pit for a new front wing and was later given a drive-through penalty, dropping him to the end of the field. Meanwhile, Nico Hülkenberg and Sebastian Vettel made up places, sitting in fifth and twelfth respectively after the first lap. Valtteri Bottas on the other hand lost positions, finding himself in tenth. Rosberg soon built a lead of over one second, giving Hamilton no chance to deploy DRS for an overtake manoeuvre. By lap 5, both Kvyat and Nasr had come into the pits for the harder compound tyre, followed by Ricciardo, Massa and Pérez one lap later. On lap seven, both Hülkenberg and Sainz Jr. made pit stops. While Hülkenberg was able to stay ahead of Massa, Sainz's stop was unfortunate and he lost time due to a problem with the tyre change. Another two laps later, Valtteri Bottas pitted and was sent out into the path of Button, damaging his front wing, which he needed to replace the following lap. He also received a five-second penalty to be served at his next scheduled stop. The leaders pitted for new tyres around laps ten and eleven, with the order now being Rosberg ahead of Vettel, who was yet to stop, Hamilton, and Räikkönen. Romain Grosjean, who started on the harder tyres just as Vettel, was up to sixth.{{cite news|last1=Butler|first1=Michael|title=F1: Abu Dhabi Grand Prix – as it happened|url=https://www.theguardian.com/sport/live/2015/nov/29/f1-abu-dhabi-grand-prix-live|newspaper=The Guardian|access-date=3 December 2015|archive-url=https://web.archive.org/web/20151203144359/http://www.theguardian.com/sport/live/2015/nov/29/f1-abu-dhabi-grand-prix-live|archive-date=3 December 2015|date=29 November 2015}}

On lap 13, Felipe Massa passed Marcus Ericsson for ninth place and one lap later, Hamilton capitalised on a mistake by Vettel and overtook him to retake second position. Vettel lost another position when he let Räikkönen pass him on lap 16, the two being on different strategies. Meanwhile, Rosberg had built up a lead of around six seconds to Hamilton. On lap 19, Carlos Sainz Jr. allowed teammate Max Verstappen to pass him, while Alonso came in for what was his third pit stop of the race, leaving him in last position. Two laps later, Verstappen created flatspots on his tyres when he locked up his brakes, forcing him to pit. He emerged in 15th position. Vettel came in for his first pit stop on lap 24, coming out in sixth place ahead of compatriot Nico Hülkenberg. At the same time, Hamilton started to reduce the gap to Rosberg in front, cutting it down to less than two seconds by lap 29. With his teammate closing in, Rosberg made pit stops on lap 32, with Räikkönen following suit, whose pit stop was delayed, losing him around four seconds. Sergio Pérez was starting to close the gap to both Ferrari drivers in front of him after pitting early. Vettel reacted on lap 41 and changed to the super-soft tyres, coming out behind both Pérez and Ricciardo in sixth. One lap later, Hamilton came in for his second and final stop, having asked his team before if it would be possible to finish the race without stopping again. He emerged twelve seconds behind Rosberg and started to cut into his advantage immediately.

Further back in the field, Max Verstappen overtook Nasr and Button to move into twelfth place on laps 44 and 46 respectively. However, he was deemed to have forced Button wide and was handed a five-second penalty to be added to his finishing time. Lap 53 saw Romain Grosjean move into the final point scoring position of tenth by passing Carlos Sainz Jr. into turn eight. Just one lap later, he took ninth place from Daniil Kvyat. At the front, Hamilton proved unable to reach his teammate, who took the checkered flag for his sixth win of the season. Kimi Räikkönen completed the podium, followed by Vettel, Pérez and Ricciardo.{{cite web|last1=Johnson|first1=Daniel|title=Lewis Hamilton pipped by Nico Rosberg again at Abu Dhabi Grand Prix 2015|url=https://www.telegraph.co.uk/sport/motorsport/formulaone/12023560/Lewis-Hamilton-pipped-by-Nico-Rosberg-again-at-Abu-Dhabi-Grand-Prix-2015.html|newspaper=The Telegraph|access-date=3 December 2015|archive-url=https://web.archive.org/web/20151203154233/http://www.telegraph.co.uk/sport/motorsport/formulaone/12023560/Lewis-Hamilton-pipped-by-Nico-Rosberg-again-at-Abu-Dhabi-Grand-Prix-2015.html|archive-date=3 December 2015|date=29 November 2015}}

In the podium interviews, conducted by former Formula One driver David Coulthard, Nico Rosberg expressed excitement over how the end of the season had worked out for him, describing the race in the United States as his "low point". Speaking about racing his teammate Hamilton, he called him "one of the best out there" and said that it was "an even better feeling to win, definitely against such opposition". Hamilton in turn praised his team for their performance over the whole season, saying that they had "surpassed their own expectations", albeit confessing that he was happy that the season was over. During the press conference, third-placed Kimi Räikkönen said: "It’s never nice to finish third but I’ll take it after previous races", pointing to a season that had been marred with small mistakes and misfortunes for him. He also stated that securing fourth place in the World Championship did not mean much to him, dismissing the idea of a "Finnish championship" between himself and Valtteri Bottas.{{cite web|title=2015 Abu Dhabi Grand Prix – Sunday Race Press Conference|url=http://www.fia.com/news/2015-abu-dhabi-grand-prix-sunday-race-press-conference|publisher=FIA|access-date=4 December 2015|archive-url=https://web.archive.org/web/20151204141715/http://www.fia.com/news/2015-abu-dhabi-grand-prix-sunday-race-press-conference|archive-date=4 December 2015|date=29 November 2015}}
