F1 2023: The teams, drivers, rules, races - Everything you need to know

The teams 

Red Bull and Ferrari are likely to be fighting for world championships again, but can Mercedes join the fight at the front of the grid after their well-documented struggles in 2022? 

Having won the last eight constructors’ world titles and seven of the last eight drivers’ titles, Mercedes have endured a hugely challenging season that was plagued by porpoising problems and a failure to grasp the new regulations. 

Promising gains have since been made leading to optimism for Lewis Hamilton and George Russell in 2023.

Elsewhere, there'll be plenty of attention and expectation on Aston Martin following Fernando Alonso’s shock switch to replace the retiring Sebastian Vettel. Can the likes of Aston Martin, McLaren and Alpine close the gap to the frontrunners? And will Williams be able to lift themselves up the grid after another difficult year? 

No new teams will enter F1 in 2023, but Porsche continue to explore future opportunities despite the breakdown of talks with Red Bull. Audi's entry for 2026 has been confirmed, while Andretti have stated their intention of joining the F1 grid.

The drivers 

Here is the F1 2023 driver line-up.

Rules 

F1 will continue to race with the new-generation cars which debuted last season.

Following safety concerns raised in the wake of the porpoising issues experienced with the 2022 cars, the FIA has intervened to submit new technical rules aimed at tackling the phenomenon. 

The FIA will raise the car floor edges by 15mm. The throat of the diffuser will also be raised and lateral floor deflection tests are due to be more stringent. 

Despite the threat of rebellion from teams, the changes were approved by the World Motor Sport Council on Wednesday 16 August. 

The F1 2023 season will feature six sprint events, double the amount held in 2021 and 2022, following approval from the FIA in late September. 

F1 will also trial a revised format for qualifying at select events with the FIA wanting to cut back on the number of tyres used across a grand prix weekend.

At two as yet unspecified races in 2023, the number of sets of tyres available to drivers will be reduced from 13 to 11. 

In addition, the tyre compound choice will be mandated for each session. Drivers will be forced to use the hard tyre in Q1, the medium tyre in Q2 and the soft tyre in Q3.

Races 

The 2023 F1 calendar has now been confirmed.

The 2023 season will kick off on March 5 - an earlier start than usual - in Bahrain before heading to Saudi Arabia.

Imola has been moved to May for the Emilia Romagna Grand Prix, taking place a week prior to Monaco.

The Belgian Grand Prix at Spa-Francorchamps has been moved to before the summer break on July 30, while the Dutch Grand Prix will be the only race in August.

Las Vegas will make its debut on November 18 - just before the finale in Abu Dhabi.
