Ferrari supplies Haas with teams of parts that they must not design and build on their own, while the junior team of Red Bull Toro Rosso will use many components of last year's RB14.
Besides these examples of what have been called "B-teams" there are concerns that large teams can be helped by their clients or affiliates who provide research and development resources.
The FIA has previously indicated that it is closely monitoring how F1 is preparing to introduce a cost limit and other resource restrictions for 2021.

"If they are able to combine their resources with other teams, or get the benefits of synergies within a budget limit, this is a problem for us and a problem for at least two other teams on the field. "
This is a reference to McLaren and Williams, who joined Renault last year and initially refused to approve Racing Point while maintaining Force India's commercial rights when the Silverstone team fell into administration.
This was among the fears that Racing Point would become closer to Mercedes.
Abiteboul said that Renault is not satisfied with the response received from the rulers on how to handle the situation for 2021
"This is a serious topic because perhaps we are saying that there are three top teams and it will be like that," he said. "Perhaps anyone who joins will have to accept that they will not be able to be competitive.

Answering the same question as Abiteboul, Red Bull team principal Christian Horner and Ferrari boss Mattia Binotto said he supported the current F1 model
They said it was the small teams that benefited from these agreements, citing the existence of Haas as a prime example.
"The convenience of Formula 1 is extremely expensive," said Horner.
"C & # 39; is ultimately a reasonable compensation between the need to be a team of builders in good standing and the possibility of acquiring those parts not listed."
Binotto said "the model itself is the right model" and is a good thing for F1.
He added: "If there are concerns, it's up to us to understand what they are and make sure we mitigate or avoid them."
