Answers: How do the 2021 Formula 1 technical regulations and development freezes work?

• Formula 1 2021 technical regulations
• F1 car development freeze
• F1 homologated components
• F1 token system for car updates

What it concludes

• The 2021 technical revolution has been pushed to 2022 because teams were unable to do development work in 2020 due to lockdown.
• F1 cars in 2021 will have their aerodynamics nerfed slightly by cutting away part of the floor, causing cars to lose about half a second in performance.
• Most components of the 2020 car will be frozen into 2021 as homologated parts, prohibiting changes unless strictly necessary for safety, reliability, cost, regulation, supplier change, or driver comfort.
• Teams will have two tokens in total to spend on developing parts that have already been frozen.
• Engine supplier changes require spending both tokens and making chassis modifications.
• Customer teams using older spec components can upgrade to the newer version at no token cost.
