2011 Formula One World Championship

After a dispute between the Formula One Teams Association (FOTA) and the FIA in the first half of 2009, a new Concorde Agreement was signed on 1 August 2009 by the then FIA president Max Mosley and all of the existing teams at the time. The new agreement provides for a continuation of the terms of the 1998 agreement, and runs until 31 December 2012.[4] The FIA published a provisional entry list on 30 November 2010, which was revised on 2 December 2010.[5] All teams competed with tyres supplied by Pirelli.

Team changes

The season started with controversy when two teams using the Lotus name were entered onto the grid, Lotus Renault GP (foreground) and Team Lotus (background).

• At the British Grand Prix, Scuderia Ferrari announced they would remove Marlboro from their official team name in response to what they described as "recent concerns" regarding their association with the tobacco brand.[10]
• In the week before the Korean Grand Prix, Force India announced that the Lucknow-based Sahara India Pariwar conglomerate had purchased a 42.5% stake in the team, giving them co-ownership with team principal Vijay Mallya. The team was subsequently renamed Sahara Force India[61]
• Hispania announced several major partnerships in November 2010. Chief among these was an arrangement that saw Williams supply the Murcia-based team with transmission systems for the 2011 season,[62] whilst forming a partnership with Spanish businessman Juan Villalonga, who was previously affiliated with Minardi as CEO of Telefónica.[63] In July 2011, Thesan Capital, a Madrid-based investment company purchased a controlling stake in the team from owner José Ramón Carabante.[64] Thesan Capital announced the team's operations would continue as they had before the purchase, and that they had no plans to change the team name or alter its operational structure. In a statement released to the media, Thesan Capital described their intentions as making the team "more Spanish" and settling the team within Spain;[65] the team had previously been supported by a complex ownership arrangement that saw team principal Colin Kolles control the physical team, with Carabante owning the rights to the team's entry.
• Lotus Racing team principal Tony Fernandes purchased the rights to the Team Lotus name from David Hunt, with the intention of renaming the team to reflect its historical counterpart for the 2011 season.[66] The use of the Team Lotus name led to a naming dispute with Lotus Cars. The team announced that they had terminated their three-year contract with engine supplier Cosworth;[67] and used Renault engines from 2011.[68]
• On 8 December 2010, Lotus Cars announced a partnership with Renault F1 that saw the British sports car manufacturer become title sponsor of the team,[69] with a view to taking full control over the next few years.[69] Confusion over the exact status over ownership of the team led team principal Éric Boullier to clarify that Genii Capital has full ownership of the team,[70] with former owners Renault retreating to a position as engine supplier. The team was then known as Lotus Renault GP,[71] and the chassis and constructor still known as Renault for reasons related to the Concorde Agreement, similar to Sauber retaining the "BMW Sauber" name in 2010 despite the departure of BMW at the end of 2009. Following team's ownership change, the team also switched their French licence to a British one.[17]
• In March 2011, it was announced that Infiniti, the luxury brand of Japanese car manufacturer Nissan of whom Renault own a 44% stake, would become a major sponsor of Red Bull Racing.[72] However, contradictory to early reports, the arrangement with Infiniti had not extended to an engine re-branding.[73]
• BMW Sauber announced in July 2010 that it will revert to the name Sauber in 2011. The team was forced to retain the BMW naming for 2010 due to issues involving television rights money that would not have been paid had the team changed their name.[25]
• After a Williams demonstration run in Caracas, it was confirmed that Venezuelan state-controlled oil company PDVSA would enter into a long-term sponsorship deal with the team,[74] replacing outgoing sponsors RBS, Philips and AirAsia. AirAsia officially left Williams F1 to concentrate on Team Lotus.
• After sponsoring the team for the 2010 season, Russian sports car manufacturer Marussia acquired what they termed a "significant stake" of Virgin Racing, with the team changing its name to Marussia Virgin Racing. Further reports confirmed that Marussia had purchased a controlling stake in the team,[75] securing their future until 2014. The team split with Wirth Research mid-season after a technical review by former Renault F1 Team engineering director Pat Symonds found that Virgin's CFD-only approach had failed.[76] In the week before the British Grand Prix, Virgin announced a technical partnership with McLaren that granted them access to McLaren's testing facilities as well as the purchase of Wirth Research facilities.[77]

On 16 April 2010, Bernie Ecclestone confirmed that there would be twenty races in 2011; all the races from the 2010 season and the addition of the Indian Grand Prix.[2] A provisional calendar was announced on 8 September 2010,[92] which was confirmed on 3 November 2010.[93] This was later revised to nineteen races with the postponement and later cancellation of the Bahrain Grand Prix.

• 2011 saw the return of the 107% rule in qualifying.[3][107] Under this arrangement, any driver who fails to set a time within 107% of the fastest lap in Q1 may not be permitted to take part in the race; for instance, if the fastest lap is 1 minute 40 seconds (100 seconds), a driver must set a time faster than 1 minute 47 seconds (107 seconds) in order to make it to the grid. However, if a driver who fails to set an appropriate lap time can show cause for his inclusion in the race – for example, if a driver failed to set a lap time in qualifying due to a mechanical fault, but had previously set a lap time within 107% of the pole-sitter's time in free practice – the stewards may allow that driver to take part in the race.
• The ban on team orders – the practice of teams ordering a driver to follow instructions that would be advantageous to their teammate (for example, ordering them to move aside and allow their teammate to pass them) – was lifted after the 2010 German Grand Prix, with the practice to be "regulated" on the race track.[108] The practice of coding instructions to conceal the nature of the order would be banned to prevent deception to the spectators and stewards. The FIA increased the maximum allowable penalty which racing stewards can issue to teams from $100,000 to $250,000.[109]
• Sole tyre partner Bridgestone announced that it would not renew its contract with Formula One at the end of the 2010 season.[110] After spending three seasons as an official tyre partner for both Grand-Am Rolex Sports Car Series and World Rally Championship auto racing tournaments respectively from 2008 to 2010, Pirelli was officially chosen as the tyre partner for 2011 by the FIA World Motor Sport Council.[3][111] The Pirelli logo on each tyre was colour-coded to identify each compound and tread pattern being used.[112] Cars had a mandatory weight distribution to provide Pirelli with a technical specification, and preventing teams making changes to the internal configuration of their cars should they prove not to suit the cars.[113] At the final test in Barcelona, it was revealed that drivers would need to make three pit stops at most races, in line with Pirelli's mandate to design a higher wearing tyre.[114]
  • The Belgian Grand Prix saw a small controversy when several teams discovered their tyres had blistered during qualifying, but were not permitted to change their tyres ahead of the race because the damage was the result of the car set-up rather than an accident.[115][116] Pirelli pointed to Red Bull Racing's practice of running camber settings that were outside their recommended parameters as the cause of the blistering,[117] and said they would be more cautious with their recommendations for Monza to prevent the problem from arising again.[118] Pirelli stated that they were willing to turn to the FIA to enforce camber limits if there was any evidence of blistering after the Free Practice sessions in Italy.[119] The FIA later announced that Pirelli's camber limits were mandatory and that any team who failed to observe them would be reported to the stewards under Article 2.3 of the sport's technical regulations for dangerous construction and would risk exclusion from the race.[120]
• The maximum height of the diffuser was cut from 175 millimetres (6.9 in) to 125 millimetres (4.9 in) and the double diffuser designs, introduced in the 2009 season, were excluded, in order to reduce aerodynamic downforce and turbulent air.[121] Banned with this are double exhaust-blown diffusers, which use exhaust gases re-routed over the diffuser to increase downforce,[122] although single blown diffusers are still allowed.[123] Controversy emerged over the use of "off-throttle blown diffusers" early in the season, with the FIA first banning the concept and then repealing the ban pending discussion with the teams.[124] The off-throttle blown diffuser increases downforce by keeping the engine spinning while the car is under braking, channelling hot exhaust gasses over the diffuser and allowing for higher cornering speeds.[125] The FIA announced that the ban would be reintroduced from the British Grand Prix, limiting the amount of throttle that can be applied during braking.[126] Tighter restrictions were to be introduced for the 2012 season. At the European Grand Prix – two weeks before the British Grand Prix – a further ban was introduced, prohibiting teams from using "extreme" engine maps in qualifying that they would not normally use in races, effectively forcing teams to use the same engine maps in both qualifying and the race.[127] The FIA estimated that the clampdown on extreme engine maps would cost some teams up to half a second per lap in qualifying alone.[128] The mid-season ban was later repealed when several teams applied for concessions to the ban, which were granted and subsequently revoked following protests from other teams.[129] An agreement signed after the British Grand Prix abandoned the ban for the 2011 season entirely, restoring the pre-Valencia rules.[130]

Red Bull RB7 rear wing showing function of Drag reduction system

• The "F-duct" system developed by McLaren and copied by other teams was banned, as the system relying on drivers blocking a gap in the cockpit was judged unsafe.[131] The Drag reduction system (DRS), an adjustable rear wing designed to increase straight line speed, was introduced in the 2011 rules. The system operates under a similar principle to the "F-duct", and is designed to aid overtaking by negating all downforce flowing over the rear wing.[3] The rules dictate that the DRS is only available to a driver within one second of the car in front on a marked designated area of the circuit,[132] after the first two laps of a race. Use of the DRS is unlimited in free practice and qualifying, but prohibited in wet conditions.[133] The system is expected to offer drivers an additional 15 km/h (9.3 mph) when passing,[134] and deactivates when the driver first touches the brakes after using the rear wing. At the Spanish Grand Prix, the FIA announced plans for a secondary DRS zone to be included on a circuit from the Canadian Grand Prix onwards.[135]
• The number of wheel tethers – the load-bearing cables connecting the wheel hubs to the bodywork – was doubled for 2011, in response to an increasing number of accidents where wheels have been torn free of their mountings, including the death of Henry Surtees in a Formula Two race at Brands Hatch in 2009.[136]
• Several smaller aerodynamic devices introduced for 2010 were also banned, including aerodynamic wheel spokes, flexible front splitters designed to lower front ride height, and modifications to the monocoque that create a V-shaped channel running the length of the car's nose.[122] The maximum aspect ratio of the "bladed" rollbar structure – pioneered by Mercedes to decrease the obstruction of air to the rear wing – was also reduced. The 2011 Lotus T128 and Force India VJM04 cars were both launched with a similar device, based on the same principle as the Mercedes device, but the Lotus and Force India variants are legal under the rules because the blade structure is thicker than the one developed by Mercedes.[137]
• KERS units were optional for all teams, after not being utilised in 2010 following a team agreement banning the devices, and the minimum car weight increases from 620 kilograms (1,367 lb) to 640 kilograms (1,411 lb), compensating for the extra weight required.[138] Gearboxes must also last for five races instead of four,[139] with an additional gearbox available without penalty for the purposes of completing an event.[140]
• At the Hungarian Grand Prix, the FIA introduced new software to track the cars in order to better spot racing incidents and provide the stewards with real-time information about drivers breaking rules.[141] The software was introduced in response to an incident at the German Grand Prix that saw Sébastien Buemi and Nick Heidfeld collide on the tenth lap of the Grand Prix, ending Heidfeld's race, but no penalty was issued to Buemi until after the race had ended.
• The FIA tightened its driving standards, moving to prevent overly aggressive driving and driving beyond the boundaries of the circuit to gain an advantage by implementing stricter penalties for drivers observed to be doing so. Drivers are limited in the number of blocking moves they can make on track, to allow easier overtaking.[142][143]
  • At the Korean Grand Prix, the FIA announced plans to introduce a stricter version of the "one move" defensive driver rule,[144] in light of a protracted on-track battle between Michael Schumacher and Lewis Hamilton at the Italian Grand Prix. Under the original set of rules, a defending driver would be entitled to make one move across the circuit to select their racing line into an approaching corner; under the regulations introduced for the Korean Grand Prix, a defending driver would be obligated to leave enough space – defined as "one car's width" – on the outside of a corner for an attacking driver to occupy, preventing the defending driver from forcing his rival off the circuit.
  • Further rule amendments granted greater powers to the race stewards. This was reported as a response to a series of on-track incidents involving Lewis Hamilton that culminated in several drive-through penalties;[144] Hamilton received six driver penalties over the course of the 2011 season, setting a new record for the most penalties in a season. From the Korean Grand Prix on, the stewards had the power to issue reprimands alongside penalties, with a grid penalty being awarded after three reprimands.
• A curfew was implemented for team personnel, barring them from accessing the circuit in the nine hours before the first session of the day[145] The rule was introduced following concerns over mechanics spending all night in the pit garage before spending the day in the busy pit lane,[140] with four exceptions allowed for the season.[146] In the event that this rule is broken after all four exceptions have been used, both cars for the offending team must start the race from pit lane. The rule attracted criticism at the Singapore Grand Prix when several teams[147] inadvertently broke curfew, using up one of their four exceptions when members of the teams' marketing divisions arrived early at the circuit.[148]
• Team members deemed to be in key roles were required to undergo accreditation for a "competitors' staff licence" in order to maintain their positions within their teams.[92] This is seen as a reaction to the actions of disgraced former Renault team principal Flavio Briatore at the controversial 2008 Singapore Grand Prix[149] and applies to key staff in all FIA-sanctioned World Championships including Formula One.

Hispania Racing hired Daniel Simon, a Hollywood concept car designer, to design the F111's livery

The pre-season testing season began immediately after the 2010 Abu Dhabi Grand Prix with a three-day 'Young Driver Test' (for drivers with fewer than three Formula One race starts to their name) at the Yas Marina Circuit. Formula Renault 3.5 runner-up Daniel Ricciardo consistently set the fastest times over the three days, driving for new champions Red Bull Racing.

The Young Driver Tests were followed by another testing session – also held at Yas Marina – for the teams to test the tyres developed by new tyre supplier Pirelli. Ferrari's Felipe Massa was the fastest during the tests, with many drivers declaring their satisfaction with the new tyres, particularly given Pirelli's short development window. Sebastian Vettel experienced an explosive puncture on the final day, though an investigation by Pirelli attributed the incident to debris on the circuit rather than a critical error with the build of the tyre.

The final test of the season was originally scheduled to be held in Bahrain, but was cancelled by the Bahraini Crown Prince due to a political uprising in the island nation. It was instead rescheduled to the Circuit de Catalunya in Barcelona from 8–12 March.[150]

Defending World Champion Sebastian Vettel won the opening race of the season in Melbourne after qualifying on pole position by eight-tenths of a second.[151] Lewis Hamilton finished in second place, and Russian driver Vitaly Petrov attained his maiden podium in third, with Renault hailing his dramatic off-season turn-around after a difficult debut season in 2010.[152] At the opposite end of the grid, the Hispania F111 cars driven by Narain Karthikeyan and Vitantonio Liuzzi both failed to qualify as their qualifying times were both outside 107% of Vettel's fastest time in the first qualifying session.[153] The Saubers of Sergio Pérez and Kamui Kobayashi were disqualified for a technical infringement when their cars failed a post-race scrutineering inspection.[154]

Vettel continued his title defence in Malaysia, taking pole from Hamilton in the dying moments of the session by just one tenth of a second. Vettel went on to win the race by three seconds from Jenson Button, who also claimed second place in the points standings; with two wins, Vettel left Malaysia with twice as many points as the McLaren driver. Nick Heidfeld took Renault's second successive podium and Fernando Alonso made a mistake, making contact with Lewis Hamilton and forcing him to pit for a new front wing, and costing him a potential podium. Hamilton himself slipped down the order after changing to the harder prime tyres and struggling with grip.

Vettel once again took pole in China, whilst teammate Webber made a poor tyre choice and was eliminated from the first qualifying period for the first time since the 2009 Bahrain Grand Prix. Vettel made a poor start in the race and was quickly overcome by the McLarens of Button and Hamilton. Button and Vettel pitted together, but Button made a bizarre mistake, mistakenly pulling up in the Red Bull pits, and allowing Vettel to get back out onto the circuit in front of him. The lead changed several times as the race progressed before Vettel settled into position, but on deteriorating tyres, he was caught and passed by Hamilton four laps from the end. Having started in eighteenth position, Mark Webber recovered to achieve the third podium place.

Sebastian Vettel earned his fourth pole of the season in Turkey, becoming the first person to start the first four races on pole since Mika Häkkinen in 1999. Vettel led the race from the lights to the flag, ahead of Mark Webber and Fernando Alonso, who gained Ferrari's first podium finish of the year. McLaren struggled with a series of slow pit stops, whilst the promise shown by Mercedes in qualifying was lost in the race when their cars were fuel-heavy and running on the harder prime tyre compound.

Mark Webber ended Vettel's run of consecutive pole positions at the Spanish Grand Prix, but it was fourth-starting Fernando Alonso that led the field into the first corner and through much of the early phase of the race. He was eventually overtaken in the pits by Vettel, and slipped down the order to finish a lap behind as Ferrari struggled with Pirelli's brand-new "extra hard" compound, which was specifically designed for endurance, but was two seconds per lap slower than the softer compounds used. Vettel went on to win the race, but Red Bull's one-second advantage in qualifying was gone by the race as Lewis Hamilton spent most of the final stint within one second of the lead. After making a poor start and slipping down to tenth place, Jenson Button used a three-stop strategy to recover to third place.

The Monaco Grand Prix was marred by a string of accidents throughout the weekend that saw two drivers hospitalised; Sergio Pérez crashed heavily at the Nouvelle Chicane in the final qualifying period and suffered a concussion, while Vitaly Petrov was briefly knocked unconscious in a five-car pile-up late in the race that saw the red flags waved and the race stopped for the first time since the 2010 Korean Grand Prix. Sebastian Vettel achieved both pole position and the race win ahead of Fernando Alonso and Jenson Button, who had been rapidly catching the race leaders at the time of the race stoppage.

After nine races, Sebastian Vettel had not finished lower than second. He is seen here taking his fifth victory of the season at the Monaco Grand Prix.

Vettel took his sixth pole of the season in Montreal, with the race severely affected by rain. The early stages of the race saw Jenson Button and Lewis Hamilton collide on the pit straight, and Button earning a drive-through penalty for speeding behind the safety car after it was deployed to retrieve the stricken McLaren of Hamilton. On lap twenty-five, the race was stopped for two hours in the face of a torrential downpour that made the circuit undriveable. When the race was finally resumed, a narrow dry line began to appear around the circuit, and Button began to work his way through the field, having run as low as twenty-first and last place after his penalty. With four laps to go, Button had passed Mark Webber and Michael Schumacher for second place and was catching Vettel at a rate that meant he would only catch the championship leader on the final lap. Vettel ran wide and off the dry line of the final lap of the race, handing Button the race win. Schumacher matched his best race result since returning to the sport, with a fourth place. At Sauber, Sergio Pérez elected not to compete after reporting that he felt unwell during the first practice session, and he was replaced by Pedro de la Rosa.

Pirelli's medium-compound tyre made its race debut in Valencia, which once again saw Vettel on pole. There was much speculation about the potential for the field to be shaken up by the introduction of engine mapping bans, but the reigning champion led for most of the race, ceding the lead only when called in to pit. He comfortably gained his sixth victory of the season when the leaders moved onto the medium compound tyres, with second-placed Fernando Alonso demonstrating that the Ferrari 150º Italia was unable to use the medium tyres as efficiently as the Red Bull RB7. With all twenty-four cars finishing the race, Hispania Racing's Narain Karthikeyan became the first man in the sport's history to finish a Grand Prix in twenty-fourth position as the race broke the record for the most classified finishers; the 2011 Chinese Grand Prix had previously seen twenty-three classified finishers.

Uncertainty over rule changes and exemptions concerning the use of off-throttle blown diffusers dominated off-track discussion at the British Grand Prix, though consensus within the media was that the issue did not directly affect the sport.[155] Mark Webber started from pole position in the race; however, Sebastian Vettel took the lead on the first lap. A mistake from Red Bull Racing in the pits allowed Fernando Alonso to take control of the race, which he went on to win by sixteen seconds, his first victory since the 2010 Korean Grand Prix. Webber caught Vettel in the dying stages of the race, but was given a late team order to maintain his position, and the Australian finished third behind his teammate. Felipe Massa was similarly catching Lewis Hamilton, whose progress had been hampered by an order to conserve fuel, for fourth position and the two made contact in the penultimate corner on the last lap, forcing Massa to run wide over the finish line. Jenson Button fell from second to fifth place in the championship when a wheel nut was improperly attached to his car during his final stop, forcing his retirement from the race.

Webber achieved his second successive pole position in Germany, while Hamilton denied Red Bull a front-row lock-out by qualifying second. Vettel was third, the first time he had qualified outside the front row since the 2010 Italian Grand Prix almost one year previously. Hamilton took the lead going into the first corner of the race, and the early stages of the Grand Prix were marked by the drivers attempting to find grip on an unusually cold circuit. As Hamilton, Alonso and Webber pulled away, Vettel struggled to match their pace following a spin at turn ten. Michael Schumacher had an identical episode at the same corner a few laps later, whilst Sébastien Buemi and Nick Heidfeld collided at the chicane, ending Heidfeld's race. There were multiple lead changes between Hamilton, Webber and Alonso, with Hamilton capitalising on a slow in-lap by Alonso and a strategy error from Red Bull to secure victory. Alonso placed second, with Webber third, while Sebastian Vettel stole fourth away from Felipe Massa when the two drivers pitted on the final lap.

Vettel returned to pole position in Hungary; however, Lewis Hamilton qualified second and was able to save an extra set of softer option tyres for the race. After mixed conditions wreaked havoc in the support races, the Grand Prix started with a wet surface. Vettel established an early lead, but was soon passed by Hamilton and Jenson Button as a dry line appeared. The positions remained constant through the halfway point of the race while Team Lotus experienced their second double-retirement in three races and Nick Heidfeld's Renault exploded after a prolonged pit stop. A mid-race shower on the fortieth lap led to Hamilton spinning, forcing Force India's Paul di Resta off the circuit and allowing Button to close the gap. The two McLaren drivers traded places several times in the greasy conditions, with Hamilton leading long enough to give him the first strategy call within the team. He opted to swap to the intermediate tyres, but the track started to dry out and he was given a drive-through penalty for forcing di Resta off the circuit, taking him out of contention for a podium finish. Jenson Button went on to win the race, his 200th Grand Prix start and the scene of his maiden victory ahead of Vettel in second and Fernando Alonso. Hamilton recovered from his penalty to take fourth position from Mark Webber, whilst Felipe Massa – who had out-qualified Alonso for the first time since the 2010 Belgian Grand Prix – was the final car classified on the lead lap in sixth place.

The Belgian Grand Prix marked twenty years since Michael Schumacher's Formula One debut, but Schumacher had a difficult start to the weekend when he lost a wheel on his out-lap in qualifying, sending him to the back of the grid. Bruno Senna replaced Nick Heidfeld at Renault, qualifying seventh in variable conditions on his return to Formula One. However, his success was short-lived when he crashed into Jaime Alguersuari on the first lap, ending Alguersuari's race and earning himself a penalty. Nico Rosberg led the early stages of the race, but was powerless to defend against Sebastian Vettel once the DRS was activated. The lead changed several times in the first half of the race, but Vettel eventually established a comfortable lead and would remain unchallenged. With Vettel winning the race and Webber finishing second, Red Bull secured their first one-two victory since Istanbul. Despite leading the race at one point, Fernando Alonso struggled with his tyres, and slipped down the running order, being passed by Mark Webber and Jenson Button, who had recovered from thirteenth on the grid. Michael Schumacher also recovered; having started twenty-fourth on the grid, he was fifth at the end of the race, behind Alonso and ahead of Rosberg. Lewis Hamilton crashed out of the race early on, making contact with Kamui Kobayashi at Les Combes. Both Senna[156] and Hamilton[157] admitted responsibility for their respective incidents.

At the Italian Grand Prix, Vettel took once again pole position, beating Hamilton by half a second, but it was the fourth-starting Fernando Alonso who led the race going into the first corner. Vitantonio Liuzzi made contact with Kovalainen and lost control, sliding off the grass and crashing heavily into Rosberg and Petrov and triggering the safety car. Vettel took the lead from Alonso one lap after the restart, while Schumacher overtook Hamilton. Mark Webber attempted to pass Felipe Massa, but the two made contact, pitching Massa into a spin. Webber continued with a broken front wing, crashing at Parabolica as he attempted to return to pit. Further down the order, Schumacher received several carefully worded instructions from team principal Ross Brawn, reminding him not to cut across the track to defend against Hamilton. Schumacher's duel with Hamilton slowed them down enough for Jenson Button to catch up; where Hamilton took thirty laps to pass Schumacher, Button passed him on his first attempt and started catching the second-placed Alonso. Vettel went on to win the race, extending his lead enough that he would need just one more win to win his second World Championship. Webber's failure to finish meant that he fell to fourth in the drivers' standings, behind Alonso and Button, while Hamilton's fourth place meant he fell further behind in the championship.

Sebastian Vettel became the youngest double World Champion at the Japanese Grand Prix, by finishing third behind race winner Jenson Button and Fernando Alonso.

Sebastian Vettel obtained his eleventh pole of the season in Singapore, and spent most of the race unchallenged. Jenson Button attempted a late push, but was held up by traffic in the final laps of the race and fell behind. Button's podium meant that the championship would remain unresolved for the time being, but with his ninth victory of the season, Sebastian Vettel closed to within one point of securing his second World Drivers' Championship and becoming the sport's youngest-ever double World Champion. Mark Webber completed the podium in third, while Fernando Alonso finished fourth, over a minute behind Vettel. An early collision with Felipe Massa meant Lewis Hamilton was handed a drive-through penalty – his sixth of the season – and slipped out of the points, but a mid-race safety car for a collision involving Michael Schumacher and Sergio Pérez helped Hamilton recover to fifth. However, the result meant that Webber, Alonso and Hamilton were all eliminated from the championship fight.

The championship came to a head in Japan, with Sebastian Vettel out-qualifying championship rival Jenson Button by just nine thousandths of a second. Vettel forced Button wide at the start, but the McLaren driver was able to recover, under-cutting Vettel in the pits during the second round of stops. Button went on to win the race, his third victory of the season, while Fernando Alonso finished second. Vettel completed the podium, securing his second World Drivers' Championship. Mark Webber finished the race fourth, with Lewis Hamilton fifth and Michael Schumacher defending from Felipe Massa to finish sixth. Nico Rosberg secured the final World Championship point in by finishing tenth, having started twenty-third on the grid.

Lewis Hamilton and McLaren ended Red Bull's monopoly on pole position at the Korean Grand Prix, with Hamilton edging out Champion-elect Vettel by two-tenths of a second. Vettel seized the lead early in the race, and remained unthreatened for the rest of the race. Hamilton engaged in a race-long duel with Mark Webber, with the Australian following an unusual strategy choice. He was unable to pass Hamilton, who collected his first podium position since his victory in the German Grand Prix. Jenson Button finished the race fourth ahead of Fernando Alonso. In finishing first and third, Red Bull secured their second consecutive World Constructors' Championship.

Vettel claimed his first "Grand Chelem" at the inaugural Indian Grand Prix, claiming pole position, the fastest lap and leading every lap of the race. The race saw several incidents on the first lap, with contact between several drivers at the first corner, and again at Turn 3. Jenson Button tightened his grasp on second place in the championship, finishing eight seconds behind Vettel, whilst Fernando Alonso completed the podium ahead of Mark Webber. Lewis Hamilton fell further behind after making contact with Felipe Massa at the halfway point, the third time the two had come together in four races. Narain Karthikeyan became the first Indian driver to compete in the Indian Grand Prix, finishing seventeenth ahead of Hispania teammate Daniel Ricciardo and Jarno Trulli, a victim of the first-lap contact.

Sebastian Vettel equalled Nigel Mansell's record of fourteen pole positions in a season when he was fastest in qualifying at the Abu Dhabi Grand Prix. Vettel however – despite maintaining the lead into the first corner – spun off at Turn 2 with a right rear puncture. He pitted at the end of the lap and had to retire with suspension damage. Hamilton led the whole race, except the pit stop phases, and won the race ahead of Fernando Alonso and teammate Jenson Button. This meant that Red Bull's podium streak came to an end, despite Webber finishing fourth.

Rubens Barrichello would race his final Grand Prix at home in Brazil, ending his 18-year career in Formula One.

At the final race of the season in Brazil, Vettel broke Mansell's record for most pole positions in a season, taking his fifteenth.[158] Webber emerged victorious, scoring his first race win since the 2010 Hungarian Grand Prix. Hamilton retired on lap 48 with a gearbox problem, joining Pastor Maldonado, Timo Glock, and later Vitantonio Liuzzi on the list of race retirements. Felipe Massa, finishing fifth in his home race, became the first Ferrari driver since Ivan Capelli in 1992 who failed to finish on the podium all season. Meanwhile, Paul di Resta finished the season as the best rookie in 13th place for Force India.
