New Sauber principal Frederic Vasseur has insisted that there are no plans to make the team into a junior Ferrari squad.
Sauber will use Ferrari's fully up-to-date 2018 engine next year, and have a closer working relationship with the Scuderia. However, that doesn't mean they will become a formal B team.
"It is good that we will be supported by one of the top teams, and not only technically," Vasseur commented on Thursday at Spa.
The Italian manufacturer already has a technical partnership with the Haas F1 team. However, Vasseur said there was no plan for Sauber to enter into a similar partnership.
"Honestly no. Haas has its own philosophy and we have ours," he insisted.
"At Sauber we already have very good infrastructure," he pointed out. "Perhaps Haas does not. We have one of the best wind tunnels in Formula 1, for example.
"We want to develop our own project with Ferrari, with the engine and gearbox at the heart," he continued. "But we can expand the number of parts we receive from Maranello.
"Perhaps at some point we will find a better option to collaborate. But we will not become a B team or customer team."
Even so, there has been speculation that Sauber could be tasked to run one or more of Ferrari's promising junior drivers.
Both Antonio Giovinazzi and Charles Leclerc have been tipped for a race seat at Sauber next season as a side result of the engine tie-up. The current line-up consists of Marcus Ericsson and Mercedes protege Pascal Wehrlein.
But Vasseur said there was no decision yet about who will be driving for the team in 2018.
"I knew you would ask me about the drivers," Vasseur said. "We will only discuss the situation and make a decision in the next few weeks."
