Ferrari has questioned Liberty Media's plans for the future of Formula One, warning it is prepared to quit the sport after 2020.
Since its takeover of F1 was completed earlier this year, Liberty Media has been pushing to future-proof the sport and make it more appealing to its fanbase. Steps have already been taken, with the FIA and FOM working together to propose a new set of engine regulations for 2021, a vision that was presented in a meeting with F1 teams in Paris on Tuesday.
Earlier this week, rivals Mercedes and Renault expressed doubts over the new 2021 engine plans, while fellow manufacturer Honda is yet to comment.
