The championship's new technical ruleset will debut in Season 9 (2022/23), before which financial regulations will come into effect from October 1 next year.
That will see teams' spendings capped at €13 million per season for the 2022/23 and 2023/24 campaigns before increasing to €15 million per season, inclusive of driver expenses.
Formula E manufacturers meanwhile will be bound by a €25 million limit over two consecutive seasons starting from 2022/23, covering costs for research and development and the like.
Jamie Reigle, Formula E's CEO, explained sustainability was a key consideration.
“Over the past 18 months, we have worked closely with the FIA and all participants in the ABB FIA Formula E World Championship to create a regulatory framework that will underpin the long-term financial sustainability for all participants in Formula E,” said Reigle.
“When combined with recent enhancements to our technical regulations and sporting formats, this financial system will strengthen Formula E's value proposition.
“In partnership with the FIA, we have created a framework which places long-term financial success at the core of the Championship which will support our existing teams and manufacturers while attracting new competitors and investment.
“The financial regulations are designed to complement our ambitious technical roadmap and enable manufacturers in Formula E to showcase the potential for electric vehicles in the most demanding racing conditions: the ABB FIA Formula E World Championship.
“The shift to electric vehicles is accelerating, Gen3 will set the standard for performance and efficiency.
“There is no turning back.”
The financial regulations will be enforced by the FIA's Cost Cap Administration.
