Formula 1's plan for cost-cutting measures has been approved by the sport's governing body the FIA.
The changes to the sporting, technical and financial regulations were passed by e-vote at Wednesday's world motorsport council meeting.
It was "due to the need to reduce costs and safeguard the sport in light of the Covid-19 pandemic", said a statement.
F1 had previously agreed to introduce a budget cap for the 2021 season, but these new measures go further.
Last Friday teams voted to accept a plan to lower the budget cap to be introduced next year by $30m to $145m (£114m).
