The sport had planned to overhaul its technical regulations for the 2021 championship in one of the largest changes in its seventy-year history. The pandemic prompted these changes to be postponed until 2022, with teams required to enter their 2020 cars in the 2021 championship to minimise the financial stress placed on the teams.[30] The sport had also planned to introduce a $175 million budget cap in 2021, which was later revised to $150 million.[31] Teams called for further revisions to $100 million, arguing that the pandemic threatened the future of four of the ten teams.[32]
