McLaren boss Zak Brown says Formula One management cannot afford to bow to the wishes of existing manufacturers like Ferrari and Mercedes when deciding the next set of regulations.
Last year Ferrari threatened to quit F1 when new owners Liberty Media presented the first post-2020 engine proposal. F1 and the FIA want to make the next set of rules more appealing for new manufacturers to join while also driving down supply costs, but Mercedes and Renault have also voiced concerns over the direction outlined in the original blueprint.
Brown is sceptical Ferrari would ever follow through with its threat and believes F1 must stay strong in its vision for the future.
