Christian Horner has conceded the superiority of his Red Bull team and rivals Mercedes is under threat in 2022.
The new season gets underway on the weekend of March 18-20 to Bahrain, the first race to be governed by drastic new technical regulations.
In what represents a major overhaul of current rules, aspects such as aero-dynamic testing, tyre widths, and development of engine power units will all be restricted.
FIA chiefs hope the changes will ensure a more competitive season, with the likes of McLaren, Ferrari, and Alpine all tipped to challenge more regularly at the front age of races.
