McLaren: F1 partner team limits have to be reviewed

The subject of so-called "B teams" has a been a recurring topic in F1 in recent years.

With the budget cap coming into force and the top teams reined in by the aerodynamic testing regulations, the benefits of sharing of IP with a partner has become more relevant than ever.

The relationship between Haas and Ferrari has been contentious among rivals since the US-owned team first arrived in the series, and it has been in the spotlight again since the new VF22 first appeared.

Although Seidl didn't want to talk about that specific case, he made it clear that McLaren, which has no alliances other than taking a Mercedes engine, wants the situation clarified.

"First of all of us in the team are very busy with ourselves this week, so I can't speak specifically about the two cars of Haas and Ferrari for example," he said.

"But it's not a secret that in general definitely these relationships that can exist within the regulations, how they are in place at the moment is a concern for us.

"That's why we are definitely of the opinion that moving forward we should put steps in place that F1 is actually a championship again of 10, 11 or 12 true constructors.

"From our point of view F1 should be to be a championship of 10, 11 or 12 teams competing where the only things you should be allowed to share are actually the power units and the gearbox environments; everything else, you have to do yourself.

"Because we know that soon as you go further you have definitely a change or transfer of IP which is performance relevant regarding the car, and that's not what F1 should be about.

"That's why we are also bringing continuously this topic up together with other teams as well that have the same concerns. That's why we have the dialogue as well
