Christian Horner has revealed that there has been no decision made as yet over Red Bull joining with Porsche for its 2026 power unit programme in Formula 1.

The Belgian Grand Prix weekend saw Audi confirm that they would be entering the sport as engine manufacturers from 2026, with new regulations in place around the power units from that season onwards.

Audi are also being tipped to join up with Sauber, especially now Alfa Romeo are leaving them at the end of 2023, but Porsche's plans are a little less clear as things stand.

For quite a while, they have been linked with joining up with Red Bull come 2026 but, as yet, nothing has been confirmed and Christian Horner says there is no rush to get things done:

“We have plenty of time, and of course, strategically, we will have to do what's right for the team and for the company. And obviously that's between the shareholders. And there are constructive discussion ongoing discussions obviously with Porsche.”

It would certainly be cool for motorsport fans to see another iconic brand like Porsche join the grid but whether that is going to happen or not remains to be seen.

VW Group is already getting back into the sport via Audi but the suggestion has always been that both they and Porsche would be on the grid for 2026, with F1's new regulations in mind.

The sport revealed said regulations over the summer break as it outlined its plans for 2026 onwards in terms of its power unit, and part of those plans was to try and make the sport more attractive to big automotive brands who'd be willing to join.

Audi are in, then, but it remains to be seen if Porsche are too.
