Formula 1 intends to freeze teams’ power unit designs from the 2023 season, ahead of the introduction of new engine regulations.
Previously, each power unit design had to be homologated for a single season. This requirement will be dropped as some specifications will be used for more than one year.
Power unit manufacturers will be allowed to introduce new specifications of engine, turbo and MGU-H once per year in 2021, 2022 and 2023. The specification will then be frozen for subsequent seasons.
Their MGU-K, energy store and control electronics will be subject to tighter restrictions. Teams may introduce a new design for each of these before the end of 2021, and a further new specification of each for the two-year period covering 2022-23. These will then be frozen.
Teams will also be required to ensure any changes they do make to their power units do not significantly alter how they are installed within a chassis.
The FIA is planning a new engine formula for 2025 to replace the current V6 hybrid turbo power unit regulations which were introduced in 2014. Progressively freezing the current designs will allow power unit manufacturers to make significant savings on their developments costs at a time when budgets are under serious pressure as a result of the pandemic.
Revised regulations detailing the changes have been circulated to the teams and are expected to be approved this week.
