Lewis Hamilton was the fastest in qualifying in Turkey, but was dropped down the grid because of a penalty due to a power unit component change. Valtteri Bottas was promoted to pole position and won the race, his first of 2021. He was followed by Max Verstappen, who re-took the championship lead, and Sergio Pérez, who took his first podium since France.

Verstappen continued his momentum in the United States Grand Prix, taking pole position. Despite Hamilton taking the lead in turn 1, Verstappen was able to win the race with Hamilton in second place, in front of Pérez. The result increased Verstappen's lead to 12 points as Hamilton collected an extra Championship point by setting the fastest lap.

Bottas took pole in Mexico City, but was spun around at the first corner by Daniel Ricciardo. Another incident behind involving Yuki Tsunoda and Mick Schumacher took both drivers out of the race, calling out the safety car. Verstappen took his second win in a row, increasing his lead from Hamilton in second, and Pérez took the final spot on the podium in his home race. Verstappen took the pole position in Abu Dhabi ahead of Hamilton and Norris. During the race, Hamilton had a better start and took the lead into the first turn.

At turn six Verstappen attempted to pass, forcing Hamilton to evade by going off the track. Emerging from the corner still in the lead, Hamilton was instructed to give up the advantage he had gained. The pair settled in their positions until the first round of pit stops, with Hamilton gradually extending his lead. He later lost much of his advantage when Pérez, Verstappen's teammate with Red Bull, and who had yet to make a pit stop, made it difficult for Hamilton to pass him, though Verstappen was unable to capitalise.

Later, a virtual safety car period allowed Verstappen to change his tyres without losing track position, which was an attempt to catch Hamilton with fresher tyres. Race director Michael Masi took the decision to allow the five lapped cars between Hamilton and Verstappen to unlap themselves before restarting the race with only one lap remaining. Upon the restart, Verstappen quickly passed Hamilton and held him off for the remainder of the lap to win the race and the championship.

Verstappen would again take pole at the first Dutch Grand Prix to take place since 1985 at Zandvoort. He held his lead from Hamilton to take the win at his home race, taking over the lead of the championship by three points. Bottas came third, overtaking Norris, who finished tenth, in the standings for third place. Bottas won sprint qualifying at the Italian Grand Prix, but was forced to start from the back of the grid after exceeding the quota of one on his power units' components.

Verstappen started at the front with the McLarens second and third. A slow stop for Verstappen meant that he ended up alongside Hamilton after the latter made his pitstop. Hamilton and Verstappen collided, ending their races prematurely. Ricciardo led to the end to take his first victory since the 2018 Monaco Grand Prix and McLaren's first victory since the 2012 Brazilian Grand Prix. His teammate Norris finished behind him to secure the team's first 1–2 finish since the 2010 Canadian Grand Prix and the first 1–2 finish of the season.

After a penalty applied to Pérez, Bottas came third from the back of the grid. After the race, Verstappen was judged by the stewards to have been predominantly at fault for the collision with Hamilton. As a result, he was given a 3-place grid-penalty for the next race and two penalty points on his super licence. Hamilton was fastest in qualifying in Brazil, but was disqualified the following day for a technical infringement. Bottas won the qualifying sprint, giving him pole position for the Grand Prix. By finishing second in the sprint, Verstappen increased his championship lead over Hamilton by two points, and Carlos Sainz Jr., who finished third, increased Ferrari's championship lead over McLaren.

Hamilton finished fifth in the sprint from last on the grid, but a five-place grid drop due to taking a new engine relegated him to tenth on the grid for the Grand Prix. On race day, both Verstappen was able to overtake Bottas on the first lap. Meanwhile, Lando Norris and Sainz were involved in a separate incident, with Norris getting a puncture.

On lap 48, Hamilton caught up to Verstappen and attempted an overtake, but failed and resulted in both of them going off track. He won the race from Verstappen, decreasing Verstappen's championship lead from 21 points to 14 points, while Bottas completed the podium. The season ended with a controversial finish, with the two title rivals for the drivers' crown entering the last race of the season with equal points. Verstappen sealed the title after winning the season-ending Abu Dhabi Grand Prix after a last-lap restart pass on Hamilton following a contentious safety car period. Mercedes initially protested the results, and later decided not to appeal after their protest was denied.

The incident led to key structural changes to race control, including the removal of Michael Masi from his role as race director and the implementation of a virtual race control room, who assist the race director. Unlapping procedures behind the safety car were to be reassessed and presented by the F1 Sporting Advisory Committee prior to the start of the 2022 World Championship season. Hamilton took pole position in Qatar, while a penalty for failing to respect double waived yellow flags during qualifying forced Verstappen to start from seventh. Verstappen quickly recovered to second place but was unable to threaten Hamilton's race lead despite setting the fastest lap on the last lap of the race. Fernando Alonso used a one-stop strategy to finish third, less than three seconds ahead Peréz in fourth, it was Alonso's first podium since the 2014 Hungarian Grand Prix. Bottas and Nicholas Latifi retired from the race after they and multiple others suffered punctures on track.

The result reduced Verstappen's lead in the Driver's Championship to eight points while Mercedes's lead in the Constructors' Championship was reduced to five points. For the 2021 season, the schedule of a race weekend was revised. Cars were under parc fermé conditions following the end of free practice three instead of qualifying, further restricting teams and drivers from making major changes to setups ahead of the race. The length of the two Friday practice sessions were cut from 90 minutes to 60 minutes. The 2021 W Series for female drivers was added to the list of support racing series alongside Formula 2, Formula 3, and Porsche Supercup.

The 2021 W Series season started at the Red Bull Ring, where it was a support event for the Styrian Grand Prix in late June. Formula 2 and Formula 3 supported Formula One on alternate weekends, rather than the same ones as a cost saving measure. Max Verstappen took his third season pole at the Styrian Grand Prix, the first of two back-to-back races at the Red Bull Ring. On the first lap, three cars collided at the third turn, forcing Pierre Gasly out of the race.

Verstappen won from Lewis Hamilton, meaning Verstappen extended his title lead to 18 points. Valtteri Bottas came third, taking his first podium since Spain. Verstappen took pole at the Austrian Grand Prix, the last race of the first triple header. On the first lap, Esteban Ocon retired with broken suspension.

Lando Norris received a penalty after being judged to have forced Sergio Pérez off track. Pérez later received two penalties for doing the same to Charles Leclerc. Hamilton finished fourth, after picking up damage to the underside of his car, meaning that Verstappen was able to extend his championship lead to 32 points. In France, Verstappen got his second pole of the season, only to go wide at the first turn and lose the lead to Hamilton in the first lap.

After regaining first with an undercut in his first pit stop, Verstappen found himself under heavy pressure from both Mercedes drivers. Verstappen relinquished his lead to pit a second time, one of two drivers to do so, returning to the track 18 seconds behind Hamilton. The speed advantage allowed him to make up the lost time, overtaking Bottas on lap 44 and Hamilton on the penultimate lap, for his third win of the year and his thirteenth win overall. Hamilton, now 12 points behind in the Drivers' Championship, did secure second, and with an overtake on lap 49, Pérez managed to take third place, pushing Bottas to fourth.

It was the first race of the season where the race winner also took pole position and the fastest lap, and the first race of the season with no retirements. Red Bull extended their lead over Mercedes in the Constructors' Championship to 37 points after the race. At the Emilia Romagna Grand Prix, Hamilton took pole from Pérez and Verstappen. Verstappen went into the lead at turn 1 on lap 1, after it started raining on race day. Mazepin and Nicholas Latifi crashed at the exit of turn 13, bringing out the safety car.

Under the safety car, Schumacher lost control of his car and spun into the pit exit, losing his front wing. On lap 31, at turn 7, Hamilton made a mistake, hitting the wall and damaging his front wing. The moment he did, his teammate Bottas and George Russell had a crash at over 320 km/h on the start-finish straight, bringing out the red flag.

After the race restarted, Norris overtook Charles Leclerc for second, but the former was overtaken by Hamilton, resulting in a podium of Verstappen, Hamilton and Norris. RaceFans noted that the report showed the FIA acknowledge that "Masi made errors but states result will stand". They also noted F1's plan for a "Remote Operations Centre" to work like video review systems used in other sports. Verstappen took pole from Russell and Hamilton in the Belgian Grand Prix in a wet qualifying session. The race was heavily affected by rain, which initially saw the start delayed by 25 minutes.

After two formation laps behind the safety car, the race start was suspended and red-flagged due to poor conditions and lack of visibility. A nearly three-hour delay followed before the race was resumed. It was not restarted, becoming the shortest race in Formula 1 history and the sixth to award half-points as less than 75% of the race was completed. Verstappen won by default, with Russell in second and Hamilton in third place. As a result, Hamilton's lead in the championship was cut to three points from Verstappen. Leclerc took pole again in Azerbaijan, this time he was able to start the race.

He led for one lap before Hamilton got past on lap 2 at turn 1. Hamilton was held up in his pitstop to allow Gasly to pass him in the pitlane, handing Verstappen the net race lead. On lap 30, Lance Stroll crashed out due to a tyre failure and brought out the safety car. With Verstappen comfortably leading with six laps to go, he suffered a tyre failure, causing him to crash on the pit straight, bringing out the safety car and then the red flag on lap 46 and 48, respectively. Hamilton went up the inside of Pérez at the restart, but forgot to adjust his brake bias and missed the corner.

Pérez won for the second time in his career and took his first win for Red Bull. Sebastian Vettel took Aston Martin's first podium in Formula One, while Gasly took his third career podium. Leclerc took pole at the Monaco Grand Prix despite crashing in the final minutes. The crash caused a driveshaft failure, meaning he was unable to start the race. Verstappen started at the front and led from Bottas and Carlos Sainz Jr. On lap 30, Bottas was forced into retirement after his front-right tyre would not come off during a routine pitstop.

Verstappen took the victory, as well as the championship lead for the first time in his career; Red Bull came away from this race with a one-point lead in the Constructors' Championship. Behind Verstappen, Sainz took his first podium for Ferrari, and Norris took his second podium of the season in third place. Under the previous rules, drivers could be disqualified as soon as such error had occurred. The race time limit for red-flagged races was also be reduced from four hours to three hours.

From the 2021 United States Grand Prix, lap times set under double waved yellow flags were automatically deleted. Valtteri Bottas finished first in sprint qualifying, but was required to start the race from the back of the grid for exceeding his quota of power unit elements. Charles Leclerc set the fastest time in qualifying, but did not start the race. Max Verstappen, in the second slot, was the first driver on the grid.

A statement from the FIA acknowledged the controversy, and that it was "tarnishing the image of the championship and the due celebration". BBC commentary around this statement was that it was an "effective admission of mistakes in the running of the race that decided the world championship". The statement was made after a meeting of the FIA World Motor Sport Council, which was scheduled for 15 December 2021, and was described as "extending an olive branch to Mercedes". On 16 December 2021, Mercedes announced that it had withdrawn its challenge to the race result. In addition, Hamilton boycotted the end of season FIA prize-giving ceremony, held on 16 December 2021, and at the time there were questions whether he would continue in F1.

Hamilton is due to be investigated for breaching the Sporting Regulations which state the top three drivers in the championship must attend the FIA Gala. Newly elected FIA president Mohammed bin Sulayem stated that there would be "no forgiveness" for Hamilton's failure to attend the event. Verstappen was required to start from the back at the Russian Grand Prix for exceeding his quota of a number of his power unit components. Norris took his first career pole position, from Sainz , and Russell.

The running order changed substantially as heavy rain began to fall in the closing laps. Hamilton took his 100th Formula One victory as well as the championship lead, ahead of Verstappen and Sainz. Hamilton was fastest in qualifying to start in first place for the first ever sprint in the British Grand Prix. On lap five of the sprint, Pérez spun, dropping him to the back of the field, and later retiring, forcing him to start from the pits for the race. On the first lap of the Grand Prix, Verstappen and Hamilton collided at approximately 290 kilometres per hour at Copse corner.

Hamilton made contact with Verstappen's right rear wheel, causing the tyre to come off and Verstappen travelled into the barrier, causing the race to be stopped temporarily. Hamilton was penalised for the contact with a ten-second penalty, which he served during his pit stop. Leclerc led most of the Grand Prix, but finished second after Hamilton overtook Norris, Bottas, and Leclerc in the late stages to win the race. Hamilton reduced his gap to Verstappen from 33 points to eight points. Max Verstappen took pole position on the opening round in Bahrain. On the formation lap, Sergio Pérez stalled at the last turn and was relegated to start in the pit lane, leaving his 11th place spot vacant.

On the first lap, Nikita Mazepin spun at turn 3, crashing into the barrier and calling out the safety car. AlphaTauri's Pierre Gasly collided with Daniel Ricciardo's McLaren the lap after the safety car ended, while Mick Schumacher spun off behind the pack. Lewis Hamilton got past Verstappen on lap 40, but on lap 53 Verstappen overtook Hamilton at turn 4, before being ordered to give the place back because he exceeded track limits. In the end, Hamilton won from Verstappen, and Valtteri Bottas completed the podium.

Lando Norris came fourth and Pérez, after starting from last, recovered to fifth. We have a safety car with 10 laps to go and the top six is all on soft tires. The broadcast is touting Verstappen's straight-line speed vs. the Ferraris, but Leclerc has been faster all day. That being said, Max is about as aggressive a driver as there is on the field.
