Formula One racing team Red Bull Racing has threatened to quit the sport once again if F1's new owners and rule makers do not drastically change the motorsport's engine formula the next time the regulations change.
Speaking to F1.com, Red Bull motorsport consultant Helmut Marko claimed that the sport needed to drastically change its engine formula by 2021 when the next set of engine regulations come into place.
Marko stated, "The latest must be 2021 that an independent engine supplier comes into F1. This is more than necessary - and the engine has to be simple, noisy and on the cost side below ten million. We are talking about a much less sophisticated engine to what we have now - a simple racing engine. There are enough companies around that could supply. So we expect from the new owners together with the FIA to find a solution at the latest by the end of this season. If that doesn't happen our stay in F1 is not secured."
While Marko's words may seem threatening, F1's new owners shouldn't take him seriously as the Milton Keynes based racing team has threatened to quit the sport on numerous occasions over the past few years. Both Marko and Red Bull owner Dietrich Mateschitz have been firing such salvos since 2014 when F1 entered the current hybrid era.
