Ferrari could lead other Formula One teams into an alternative championship if the sport becomes too much like the US-based NASCAR series, but says they hope it doesn't come to that.
Speaking to reporters at the Italian team's pre-Christmas lunch in Maranello, Fiat Chrysler chief executive Sergio Marchionne said his
previous threats to take Ferrari out of the sport after 2020 should not be taken lightly.
He also announced a February 22 launch date for the team's 2018 car and said Ferrari should be challenging for the title after finishing runners-up to Mercedes this year.
Marchionne said Liberty Media, the US-based company which took over Formula One in January and sidelined former commercial supremo Bernie Ecclestone, was learning the ropes.
He took issue, however, with the approach taken by former Ferrari technical director Ross Brawn, the Formula One managing director who won titles with his own Brawn GP in 2009 before serving as Mercedes F1 team boss.
"The thing that most annoys me is that there is an experienced man like Ross Brawn there who is looking for ways that go against the DNA of Formula One," the Gazzetta dello Sport website quoted Marchionne as saying.
"Making cars all the same with simpler and cheaper engines is like NASCAR, it doesn't interest us," he added. "We need to find a balanced solution for the future that satisfies everyone and I think we will do it in time.
"Otherwise Ferrari will leave. If they (sceptics) think we are bluffing, they are playing with fire."
Most of the Formula One teams have contracts that expire at the end of 2020 and Marchionne said Ferrari would be able to walk away.
"I think that Ferrari has the strength to drag others as well to an alternative championship," he added.
There have been similar threats in the past from Ferrari, before Marchionne's time, without any of them coming to anything.
Marchionne is a very different character to former Ferrari chairman Luca di Montezemolo, however, and Ecclestone told Reuters in November he did not consider it an empty threat.
