Mercedes open to F1 customer deal similar to Ferrari-Haas arrangement

Mercedes currently supplies its gearbox and complete hydraulic systems to Force India, while Williams only uses its engines and associated systems.

Williams backer Lawrence Stroll is keen to have a closer relationship and is pushing for the Grove team to use more Mercedes technology, and has already pitched the idea.

However deputy team principal Claire Williams has made it clear that she wants her team to remain independent and be perceived as a constructor.

Wolff says that Mercedes would consider a Haas-style deal if it made sense for all parties.

"We have seen that the system between Ferrari and Haas has worked, it has worked for both," said Wolff.

"It's an interesting revenue filler for Ferrari, and in terms of synergies, there is a lot you can work on, and it has functioned for Haas.

"They are a very competitive team without having built on a legacy, or without having built on knowhow that would have taken years and years to collect.

"So far the system is very successful, and of course our thinking goes in that direction - whether it is Williams or Force India to collaborate.

"But we are in the middle of a tough fight for this 2018 championship, so we need to prioritise."

Asked whether Mercedes could do such a deal next season he said: "We can do something for 2019. We have certain capacity."

Wolff said it was too early to say whether Mercedes could work with both of its teams.

"The devil is in the detail," he added. "It is not only about production, but it's also it is about getting in order not to distract yourself, you need to do it properly.

"It would be a long-term project and not something where you can expect a huge impact for 2019. You need two or three years to ramp up.

"It can be beneficial, but it needs to be done in the right way because you need to get the balance right between distraction and really optimising the synergies. It's not trivial."
