Red Bull team principal Christian Horner says it is “too late in the day” to be making changes to Formula 1’s 2023 floor rules to help a “certain team”.

In an attempt to combat the porpoising issues that teams have suffered with under the 2022 regulations, the FIA announced last week a raft of measures planned for next year.

These tweaks are significant enough to have an impact on car designs that has left more than half of the grid unhappy with the proposed changes.

The FIA has insisted it would press on with its actions as it feels they are a “significant safety matter”, but Horner has suggested Mercedes is behind the push for a change as they have struggled with porpoising this season.

Speaking to Sky Sports F1 at the French Grand Prix, Horner said while the planned clampdown on flexi-floors was not a concern for Red Bull, he was clear it was too late to make “fundamental” changes to the 2023 regulations.

“I think the problem is what they’re looking at as a remedy for next year,” Horner said.

“The directive [for Spa], it’s neither here nor there for us. I think there’s an awful lot of lobbying to change the regulations significantly for next year, so a certain team can run its car lower and benefit from that concept.

“It’s a very late point in the year to be doing this. I think the president is doing the right thing, he’s collating all of the information, and hopefully a sensible solution can be found. Because it’s too late in the day for fundamental regulation changes, which something like that would be.”

Discussing the matter further, Horner hoped the FIA’s intervention wouldn’t go too far, acknowledging Mercedes has seemed to have got on top of the excessive bouncing in recent races.

“Just run the car higher: it’s easy. We haven’t had a problem all year. There’s only one team that’s had a big problem,” Horner added.

“We’ve got some of the most talented engineers in the world in this sport, and I can almost guarantee you, if we come back next year, there would probably be no cars with issues.

“With the last few races, it’s looked OK. Here it looks OK. So I think what we don’t want to do is knee-jerk into an overreaction that could have fundamental impacts on next year’s cars.”
