Red Bull advisor Helmut Marko warned the team could pull out of Formula One over its rules and organisation after a disappointing opening race in Australia.

Marko said the Austrian team was "unhappy" with the current situation, as team principal Christian Horner called for new regulations to level the playing field.

Mercedes' Lewis Hamilton and Nico Rosberg tore away to a one-two finish in Melbourne, 30 seconds ahead of the next driver, in an ominous sign for the other teams.

Red Bull's Daniil Kvyat suffered a gearbox problem on his way to the starting grid and Daniel Ricciardo was sixth out of just 11 cars to finish.

"We are unhappy with the way Formula One is regulated and run," Marko said. "Therefore we will also be thinking about an exit scenario if the cost-benefit analysis no longer adds up."
