Formula One: Complete guide to all 20 drivers on the 2021 grid

The 2021 Formula One season finally revs into action at the Bahrain Grand Prix this weekend. With pre-season testing now completed in Sakhir, the 10 teams are ready for the 23-race year, culminating in the Etihad Airways Formula One Abu Dhabi Grand Prix on December 12. With the traditional curtain-raiser at the Australian Grand Prix moved to November for logistical purposes amid the coronavirus pandemic, the F1 season will instead begin in Bahrain with Friday's practice sessions, before qualifying on Saturday and the race on Sunday. The notable addition to the 2021 calendar is the first ever grand prix in Saudi Arabia , which will be the penultimate race weekend prior to the finale in Abu Dhabi. There are also some eye-catching changes on the grid. Here is a complete guide of the 20 drivers competing in the upcoming F1 season. With a record 95 race wins and a record-sharing seventh world title, Hamilton has done what many thought was unimaginable, occupy the same lofty pedestal as Michael Schumacher. The newly knighted Sir Lewis , who also has more pole positions and podiums than any other driver in the championship's history, will now be favourite to earn the right to be considered Formula One's GOAT with an eighth title in what could be his swansong. He has emerged as so much more than just a supporting teammate chasing crumbs off Hamilton's plate, although he is still more often than not fastest on Friday practice but not 48 hours later when it matters most. For Hamilton, Bottas "does his talking on the track, I have a huge respect for him". That came after the Finn had deprived him of pole in the Emilia Romagna Grand Prix. He has signed, like Hamilton, a one-year contract extension until the end of this season. The Monegasque will be anticipating a better season than last, which shouldn't be hard after a misfiring car contributed to the team's worst performance in 40 years. He finished eighth, making the podium only twice, and will be anxious to forge new and altogether more positive memories with an improved car to capitalise on his prodigious talent. He replaced two-time world champion Fernando Alonso at McLaren and now four-time champion Sebastian Vettel at Ferrari to form the team's' youngest pairing in the past 50 years. In Sainz, Ferrari feel they have found an ideal fit for their family, pointing to his technical ability, talent and character. Last term Sainz came in sixth, with his new teammate two places behind. Byron Young | Carlos Sainz gets his chance to prove there is more to F1's nearly man Unbridled ability, a razor sharp competitive streak and streetcar racing nous have contributed to his position as heir apparent to Hamilton's crown. A drop in form by Red Bull and Mercedes' relentless excellence has counted against his title aims, but a win in the last race of 2020 in Abu Dhabi and strong form in testing last week are encouraging signs for a revival. Verstappen was best of the rest last term, with two wins and 11 podiums. An improvement is on the cards, with Honda supplying a new engine in their final season. It would be one almighty leaving gift if the Dutchman was to break Hamilton and his team's hegemony. Things looked bleak for the Mexican in terms of remaining on the grid for 2021 in the run up to the penultimate race of last season. He was out of contract with Racing Point and without a win from 189 starts. But he conjured up a stirring maiden victory to earn a call from Red Bull to replace Alexander Albon. Ninth with 97 points in his second season last year, the 21-year-old Englishman is confident of being more than a match for new teammate Daniel Ricciardo after proving an equal partner to Ferrari's new driver Sainz. He anticipates making ripples in the F1 pool in 2021. "I am in that earlier phase of my career but I still need to perform very well, and there are no excuses for me anymore." The Australian is counting on McLaren's upturn in fortunes after a barren spell to help reignite his career after a quiet two years with Renault. Beneath the surface of his endearing good nature lurks a fiercely ambitious streak, which at 31 and after nine full seasons, is stronger than ever. His brilliant best was dimmed by the under-performing Renault over the past two years. At McLaren, he will want to become better acquainted with the podium after only two visits in the past two seasons. The 2005 and 2006 world champion with Renault returns to his first love after a two-year flirtation with Le Mans, the Dakar Rally and Indy 500. He insists that at 39, a two-year exile, and jaw surgery following a cycling accident last month, he is in the best shape of his career. Alonso last competed in F1 car for McLaren in 2018 but says he is now a more complete driver after winning Le Mans twice but failing to win the Indy 500 and emulate Graham Hill by completing the so-called Triple Crown of winning the Monaco Grand Prix, Le Mans and Indy 500. Byron Young | Fernando Alonso's F1 return is exciting, intriguing and controversial – just like the superstar driver himself Ocon says he is keen to relive "that podium feeling" after experiencing it for the first time when second in Bahrain for the rebranded Renault team. Fast, determined, unafraid of tough battles, and at 24 he is impatient for his first win in the top division after graduating as GP3 champion in 2015, proving himself with Manor and Force India and a year's sabbatical 'on the bench' at Mercedes. If his startling showing in pre-season testing is anything to go by this diminutive newcomer is poised to make a sizeable impact on his first season. With only Verstappen in front of him, Tsunoda clocked the second-best time. The first Japanese driver to compete in F1 since Kamui Kobayashi in 2014 stands at just 1.59 metres (5ft 3in) and has hit the gym to bulk up after confessing that he "couldn't even lift" his head after driving 123 laps in Abu Dhabi testing in December. He was named FIA rookie of last year after finishing third in his debut season with British team Carlin in the Formula 2 championship. A year after demotion from Red Bull to their sibling team the Frenchman conjured up his debut Grand Prix success in a chaotic race at Monza for only his team's second ever win. He took time to recover from a bruising experience alongside Verstappen at Red Bull and the 2016 GP2 champion will be keen to build on last season's form. The four-time champion with Red Bull endured a miserable last season with Ferrari, coming in a humiliating 13th in the drivers' championship. But now the German is back talking about a fifth world title for the rebranded Racing Point team. He concedes he was not at his best in 2020, but says he has made peace with that and the winner of 53 Grands Prix believes he still has all the ingredients to win the championship again for the famous British marque returning for the first time to F1 since 1960. The 22-year-old son of team owner Lawrence Stroll may have had a cushioned arrival in the sport but his performances have helped silence those who questioned whether he deserved his place on the grid. Raw speed, competitive zeal and a beneficial partnership with former teammate Perez helped produce his first pole position in Istanbul in treacherous conditions. He came in 10th in the season standings on 74 points, a tally to build on this term. Hamilton wasn't the only record-breaker in 2020 with Raikkonen starting a record 323rd race at the Eifel Grand Prix at the Nurburgring. He arrived a fresh-faced 21-year-old at Sauber in 2001, went on to collect the 2007 world title with Ferrari, and now is enjoying the twilight of his career with his first team albeit under a different name. A modest 16th place and four points last term is a target he will enjoy eclipsing. He matched his more illustrious teammate's points haul last term after extending his tenure at the team with a flourish to the end of an unimpressive opening half to 2019. Runner-up in GP2 to Gasly and can aim at continuing his progress with a secure midfield place. Nine years after dad Michael's last race, the Schumacher name is back on the grid with the F1 legend's son Mick graduating as Formula Two champion to drive for Haas. The 22-year-old says he's proud to follow in his famous father's footsteps, but another son of a world champion has warned of the pressures he will have to face. "It's not easy to be the 'son of'. And with Mick, it is 10 times more difficult, because Michael's era was not so long ago and he was much more successful," said Nico Rosberg. The team's second rookie is the 22-year-old son of billionaire Dmitry Mazepin, a non-executive director of Russian company Uralkali, the main title partner of the Haas team. He takes his place only after the team had to hold an internal investigation over a controversial social media video. For his second season Russell was tipped for stardom by Mercedes chief Toto Wolff after the 23-year-old stepped in for the Covid-19 quarantining Hamilton in Bahrain, upstaging Bottas in Friday practice. He would likely have stolen the show in the race itself only for a bungled pit stop and puncture that left him in ninth. With changed ownership, former champion Jenson Button in as a senior advisor, the gifted Russell can approach the campaign with plenty of optimism. Like Stroll, the 25-year-old Latifi is the son of a billionaire. In his second season after graduating as the team's reserve driver last term and still searching for his first point.
