In a statement on their website, the FIA wrote 

‘’The World Motor Sport Council has approved by e-vote a number of key changes to regulations to allow it to react more swiftly to the challenges currently posed by the global COVID-19 pandemic.   

In addition to these changes relating to the wider motor sport landscape, the World Council has also approved a number of changes to regulations for specific championships.’’ 

The raft of changes and new rules can be read below.  

- Mercedes' innovative DAS system banned for the 2021 season 

- No tyre testing will take place in 2020  

- Any more rule changes during the 2020 season will only need the approval of 60% of the teams.   

- An optional one-day young driver post-season test replaces the usual three-day test held in Abu Dhabi.   

- All Power Unit manufacturers must observe a three-week shutdown period. The teams must do this for 21 consecutive days during months of March and/or April.  

- In the event that public health concerns or government restrictions continue beyond the shutdown period initially envisaged, the competitors and the FIA shall consult in good faith to determine whether the shutdown period should be extended and the length of any such extension, in order to ensure equal treatment as between all competitors. 

- If the calendar has 14 or fewer events each driver will be permitted only 2 Power Units. More changes to specific elements if the calendar ends up with less than 11 events.  

- In order to prevent testing which aims to develop for the 2022 season [it was confirmed earlier this month that the 2021 regulations pushed back a year following the outbreak of the coronavirus], from 28/03/2020 until 31/12/2020, [Restricted Wind Tunnel Testing] may only be carried out using a scale model that substantially complies with the 2020 or 2021 F1 Technical Regulations. No wind tunnel testing may be carried out using car geometry partially or wholly compliant with and/or substantially derived from the 2022 F1 Technical Regulations.
