New constructors in the race to enter F1
While doubts persist about Porsche's entry into F1 alongside Red Bull, other manufacturers are on the lookout in case the agreement fails. Their names have not been revealed yet.

Red Bull and Porsche were supposed to join forces in 2026 with the new engine regulation. The agreement involved a 50% stake from Porsche in the Milton Keynes company and would assist Red Bull in developing the new engine.
But contradictions between the two parties have created difficulties in the agreements. Red Bull has reevaluated its demands and asked Porsche to comply with their conditions, which Porsche did not accept. The partnership between the two groups seems almost impossible.
One of the only solutions would be for Porsche to get involved in Red Bull’s powertrain division. But the German manufacturer didn’t want to just be an engine supplier.
Porsche was supposed to accompany Audi in entering Formula 1 as early as 2026. It is possible that we may only see Audi arrive in the championship.
But the F1 director Domenicali hinted that other constructors were ready to arrive and that they had kept a low profile for the moment.
I believe that we as F1 are currently a very inclusive platform. There are also other manufacturers sitting at the engineers’ table who prefer not to reveal themselves.
Domenicali believes that the regulations for the 2026 F1 season are very attractive to the constructors and that the sport is strong enough to withstand changes in the teams. Arrivals or departures would not jeopardize Formula 1.
« As far as we are concerned, we’re not afraid. In the latest Concorde Agreement, we only asked for a one-year notice from teams or constructors intending to withdraw from Formula 1, the rules used to be much stricter in the past. »
This change has been included because we feel strong and robust enough to move forward anyway, and there are very good backup plans.
Today, like never before, we have a mix of top-level teams, manufacturers, and engine suppliers. If anything changes, we know what to do.
The future of F1 looks bright, and the arrival of another manufacturer could happen if Porsche fails.
