Formula One bosses and teams have agreed to push back the radical rule changes originally planned for 2021 amid the economic uncertainty caused by the coronavirus pandemic.
F1 had set aside next year to introduce a radical overhaul of car designs, which it hoped would allow for closer racing and more overtaking. However, the first seven races of the current season have been suspended indefinitely in the midst of the pandemic.
With the global economy also suffering a significant downturn, F1 teams had voiced their concerns about the imminent rule change, which under normal circumstances would require a ramping up of development over the coming months.
On Thursday, teams met with F1 bosses and FIA president Jean Todt and unanimously agreed to the change.
To further control costs at this uncertain time, it has been agreed teams will use their 2020 chassis for 2021, with a statement on Thursday saying, "the potential freezing of further components to be discussed in due course".
The cost cap, which was part of the sweeping 2021 changes, will remain in place as planned.
F1's teams had already united to agree to bring forward and extend the mandatory shutdown of facilities, usually reserved to split up the season in August. Each team now must shut its factory for three consecutive weeks at some point in March and April.
