Ferrari chairman Sergio Marchionne insists Ferrari is serious about its threat to withdraw from Formula One if Liberty Media does not change its plans for the sport's immediate future.
Ferrari, the only team to have contested every world championship since F1's inaugural year in 1950, issued the warning in early November after Liberty outlined its blueprint for the next cycle of engine regulations, set to start in 2021. The sport's new owners, who took control in early 2017, are believed to be considering ways to redistribute prize money among F1's teams, while also looking at how to enforce a cost cap to address the current disparity in performance between teams on the grid.
