Dr Helmut Marko has issued another quit threat, this time if the Red Bull-Honda partnership does not work out.

Red Bull’s ever-outspoken motorsport advisor is never too far from saying the four-time World Champions will leave Formula 1, but has suggested this time that their upcoming partnership with the Japanese manufacturer is their last roll of the dice.

“We are pleased with the great cooperation with Honda for the coming years, and if this cooperation, for whatever reason, does not work as expected, then Red Bull will leave Formula 1,” Marko told Speedweek.

Honda have produced some impressive results this season with Red Bull’s junior team, Toro Rosso, with Pierre Gasly’s fourth place finish in Bahrain the absolute pick of the bunch.
