An absolute nothing season. Genuinely can't remember one thing about it.
Definitely not the best season, but there were some moments e.g. Max Verstappen, Mercedes being beaten on merit a couple of times (and not managing to get either car on the podium on 2 occasions), the USA race.
Bring on 2016!
Some stats/facts re Abu Dhabi and 2015:
Hamilton equals Schumacher's 17 podiums in 1 season (from 2002), although 2002 only had 17 races.
15 front-row lockouts for Mercedes - beats last year's 12.
12th 1-2 for Mercedes - beats last year's 11.
32 podiums for Mercedes (out of a possible 38) - beats last year's 31.
703 points out of a possible 817 for Mercedes - a record percentage. They scored 2 more points than last year, despite the double-points race.
Rosberg's 6th consecutive pole - something Vettel has yet to manage.
Hamilton scored 11 poles to Rosberg's 7 - the reverse of last year.
Hamilton (car #44) set his fastest lap on lap 44, and Rosberg's time on that lap was 44.444s.
Top 10 drivers in the Drivers' Championship consist of 5 pairs of team-mates in order: Mercedes, Ferrari, Williams, Red Bull, Force India.
Every race this season has featured the German national anthem on the podium - the British anthem managed this in 1991, 1992, and 1993.
Raikkonen's 3 podiums in 2015 came in the 3 races that finished at night (Bahrain, Singapore, Abu Dhabi).
Every win in 2015 was scored by a manufacturer team - first time since 2006.
First time Alonso has scored fewer points than his team-mate in a season (although he lost on countback in 2001 and 2007, and was behind Trulli when Trulli was sacked from Renault in 2004).
First lap crash involved cars 12, 13 and 14. This falls some way short of Belgium 1998, where cars 15-22 (and others) were all involved in the first lap crash.
2nd consecutive year in which only 3 drivers won races, and 2nd consecutive year in which only 2 teams won (first time either of these has happened in consecutive years).
Vettel scored the same number of points (278), wins (3, the first one being in Malaysia), and podiums (13) as Alonso in 2012.
First time ever that one driver has won 3 consecutive races from pole with another driver starting and finishing 2nd in all 3 of those races.
Rosberg's 1000th lap led - Stirling Moss is the only non-World Champion with more.
18 poles from 19 races this season for Mercedes – equals last year as well as Red Bull in 2011. Also, McLaren in 1988 and 1989 and Williams in 1992 and 1993 only missed pole once (and in 1993 it was only in the last race), with all those seasons having 16 races. There has arguably been a 100% record – Ferrari in 1952 managed pole in every race apart from the Indy 500 (7 poles in total).
Hamilton has managed 2 poles, 2 fastest laps, and 2 wins at Abu Dhabi – all of them in different races. His fastest laps came in the only 2 years that the race has been won from pole (2010, 2015).
Rosberg’s win means that he has scored more points in 2015 than in 2014 (322 vs 317). Hamilton has managed 3 points fewer than in 2014 (but that is skewed by the double-points).
Alonso’s first season without a podium since 2001 (and 2002 in which he did not compete), and also the first season since 2001/02 that he has not led a lap.
Each of the last 12 races has seen Hulkenberg either finish 6th, finish 7th, or not finish at all.
4th season in a row in which Grosjean has taken part in exactly 19 races.
2nd race in a row that the only DNF has occurred on lap 1.
Every points-scoring driver (which was all the drivers except Magnussen and the Marussias) managed at least 1 top 8 finish in 2015.
9th non-mechanical DNF for Lotus this season – no other team has had more than 3.
Verstappen’s first no-score since Belgium – Hamilton now has the longest unbroken streak (6).
First season without a Red Bull win since 2008.
First season since 1980 in which McLaren have not led a lap.
Every race this season has seen at least 1 German driver on the podium.
103 front-row starts for Mercedes – same as Red Bull.
18 front-row starts this year for Hamilton – equals Vettel in 2011.
First time since Brazil 2009 that Vettel has gone out in Q1 without a mechanical issue (first time in a dry qualifying session since Monaco 2008). He finished in the top 5 in both of those races, as well as in this one.
Rosberg is the only driver to have managed 15 podiums in one season without winning the Championship that season – and he has now done it twice.
First time a team has officially seen its drivers finish 1st and 2nd in the Championship in consecutive years since Williams in 1996-97 – however, Schumacher was stripped of 2nd place in 1997. The last time before that was McLaren in 1988-89.
Out of the 17 times that Rosberg has started on pole with Hamilton in P2, each driver has won 7 races.
Raikkonen’s 80 podiums (equalling Senna) consist of 3 round figures – 20 wins, 30 2nds, and 30 3rds.
15 out of 19 races were won by the driver leading at the end of lap 1 – only 1965 (8/10) has a higher percentage.
