Red Bull Formula 1 chief Christian Horner has revealed huge apprehension ahead of the 2025 season, issuing a stark warning to the sport and its governing body, the FIA.
Red Bull embark on their 2025 season looking to gain back some pride having finished third in the constructors' standings last campaign.
Max Verstappen did still manage to win the drivers' championship, his fourth consecutive title, but even that came with its tough times, with Red Bull's performance struggles leading to him having a 10-race winless streak in the middle of the year.

2024 constructors' champions McLaren appear to be the favorites heading into the season, with drivers Lando Norris and Oscar Piastri now proven race winners.
Elsewhere, Ferrari has a supremely talented driver lineup, with qualifying maestro Charles Leclerc being joined by seven-time world champion Lewis Hamilton for 2025 and beyond.
Red Bull will be without key team members Jonathan Wheatley and design genius Adrian Newey heading into that particular season, as they start a new era themselves. The team will be powered by their own power units for the first time, starting a powertrain department alongside car manufacturer Ford.
2026 is set to see a huge aero and engine regulation change
Now, Red Bull team principal Horner has issued his concerns surrounding the 2026 regulation changes, as he looked ahead to the upcoming championship battles.
"This year is set to be super, super competitive, which is very, very exciting," Horner told TalkSport. "I think where there is a little bit of apprehension is we have a big regulation change for 2026.
"So it's the first time car and engine in probably 50 years have been changed simultaneously. And inevitably there will be a divergence of performance at that point.
"It's really important that FIA and the commercial rights holder, they make sure that the boundaries of that, that there's the ability to recover quickly."
