Formula 1 2023: All you need to know about the teams and drivers

All you need to know about the teams and drivers in 2023 (all facts correct as of 1 February).

Alfa Romeo - Zhou Guanyu (car number 24), Valtteri Bottas (77)

Alfa Romeo finished sixth in the constructors' championship last year - level on 55 points with Aston Martin - and stick with the same driver pairing of Zhou Guanyu and Valtteri Bottas.

China's Zhou starts his second campaign in Formula 1 following a rookie season which included a major crash on the opening lap of the British Grand Prix at Silverstone.

The 23-year-old walked away uninjured after sliding upside down across the gravel trap and vaulting the barriers. He finished the season 18th in the standings, with six points.

Former Mercedes man Bottas, meanwhile, was 10th in the championship. The 33-year-old Finn's best result was a fifth-placed finish at the Australian Grand Prix in Melbourne.

Alpha Tauri - Yuki Tsunoda (22), Nyck de Vries (21)

Alpha Tauri will present a new driver line-up at the opening race in Bahrain in March following a difficult season last year.

Japanese driver Yuki Tsunoda waves goodbye to former partner Pierre Gasly and will now drive alongside Dutchman Nyck de Vries at Red Bull's sister team.

De Vries made his case for a full-time seat in F1 when he stood in for Alex Albon at Williams at the Italian Grand Prix in September, finishing ninth on his race debut.

Alpine - Esteban Ocon (31), Pierre Gasly (10)

This could be a team to watch in 2023 as Alpine get their wish of an all-French pairing.

Gasly and Ocon, both 26, have a long history that dates back to their early years in karting. The childhood friends from Normandy fell out but now reunite to become the first entirely French driver line-up in F1 since 1994.

Alpine beat McLaren last year to take fourth in the constructors' title race, while Ocon finished six places higher than new team-mate Gasly - who was driving for Alpha Tauri - in the drivers' championship.

Aston Martin - Lance Stroll (18), Fernando Alonso (14)

With four-time world champion Sebastian Vettel now enjoying his retirement, Aston Martin look to another multiple title winner as they seek winning performances.

Fernando Alonso switches from Alpine after signing a surprise multi-year contract with the team in August. The 41-year-old Spaniard said he was "very impressed" on his first outing with Aston Martin in November.

Canadian Lance Stroll, 24, begins his eighth season in Formula 1 and finished 2022 in 15th spot in the championship.

Ferrari - Charles Leclerc (16), Carlos Sainz (55)

Charles Leclerc and Carlos Sainz are preparing for their third season as team-mates at Ferrari but will this be the year either driver can bring success back to the Scuderia?

Leclerc started last season superbly with wins in two of the first three races, but the 25-year-old Monegasque driver only secured one more race victory in 2022 and had to fight off Red Bull's Sergio Perez for second place in the standings.

Spaniard Sainz, 28, celebrated his maiden F1 victory from pole position at the eventful grand prix at Silverstone in July, and also took a further eight podium places across the campaign.

Haas - Kevin Magnussen (20), Nico Hulkenberg (27)

Haas are making changes for the new season, with a familiar face returning to the grid to partner Kevin Magnussen for the US-based team.

Germany's Nico Hulkenberg, 35, will take the place of Mick Schumacher, who heads to Mercedes as a reserve driver. Hulkenberg will be returning to Formula 1 for a full season for the first time since being dropped by Renault in 2019.

It was a memorable year for Magnussen last term as the 30-year-old Dane sensationally put his car on pole position for the sprint race at the Sao Paulo Grand Prix.

McLaren - Lando Norris (4), Oscar Piastri (81)

McLaren had to settle for fifth place in the constructors' title fight last year, and are hoping Lando Norris and rookie Oscar Piastri can begin a new era of success at the team.

Piastri joins as a replacement for fellow Australian Daniel Ricciardo but his announcement was far from smooth as the 21-year-old rookie became involved in a contract dispute with Alpine.

Norris, meanwhile, secured just one podium finish in 2022 - the 23-year-old Briton coming third at the Emilia Romagna Grand Prix early in the season.

Mercedes - Lewis Hamilton (44), George Russell (63)

Can Mercedes put their 2022 woes behind them and regain the type of form that helped them achieve eight consecutive constructors' championships?

It took until the penultimate race in Brazil for the Silver Arrows to celebrate a grand prix victory following a campaign of porpoising issues and lack of competitiveness.

The Mercedes win did not come via seven-time world champion Lewis Hamilton, however, as the 38-year-old Briton failed to add to his 103 Formula 1 victories over the course of last year's 22-race season.

His team-mate and compatriot George Russell, 24, was the man to deliver success at Interlagos, sealing wins in both the sprint event and the 71-lap grand prix - his maiden successes in the sport.

Hamilton would eventually finish sixth in the drivers' standings - 214 points behind champion Max Verstappen.

Red Bull - Max Verstappen (1), Sergio Perez (11)

Red Bull were the dominant force last season, securing their first constructors' trophy since 2013, at the United States Grand Prix in October.

Max Verstappen was in a class of his own, the Dutchman claiming his second Formula 1 title with four races to spare amid confusing circumstances in Japan.

The 25-year-old also broke the record for wins in a season, securing his 14th victory in Mexico to move clear Michael Schumacher and Sebastian Vettel, who won 13 races in 2004 and 2013.

His Mexican team-mate Sergio Perez was victorious in Monaco and Singapore but the 33-year-old was beaten by Leclerc to second place in the championship at the final race in Abu Dhabi.

Williams - Alex Albon (23), Logan Sargeant (2)

The new regulations introduced in 2022 failed to help Williams build on their eighth-placed finish in 2021, and they ended last season bottom of the constructors' pile.

Alex Albon finished inside the top 10 in Australia, Miami and Belgium, and qualified in a season-high sixth place in the third of those races.

The 26-year-old Thai-British driver will not be alongside Canadian Nicholas Latifi at Williams this season, and will instead be partnered by Logan Sargeant.

Rookie Sargeant, 21, will become the first American to have a full-time Formula 1 seat since Scott Speed at Toro Rosso 16 years ago.
