Red Bull team principal Christian Horner has been accused of 'crying out and moaning' by Mercedes Formula One boss Toto Wolff over his calls for Formula One to equalize engines.
Red Bull, who use Renault engines, had a poor weekend at the season-opening Australian Grand Prix, with one car lapped and the other retiring, whereas Wolff's team took a one-two with Lewis Hamilton and Nico Rosberg in Australia.
Wolff said that Red Bull and engine supplier Renault should get their heads down and work hard and sort it out, the BBC reported.
Horner had questioned if it was healthy to have this, adding that the FIA have an equalization mechanism within the rules, insisting that Mercedes perhaps need to look at that.
Wolff, whose team won 16 of the 19 races last year, responded to the claim by saying that if one comes into Formula One and tries to beat each other or perform at the highest level and equalization is what one needs after the first race and they cry out after the first race, it is not how Mercedes has done things in the past and not how they have moaned.
The FIA is not expected to make any moves to appease Red Bull.
Horner said that the Renault engine used by Red Bull in Australia had less performance than the one they used at the final race of the 2014 season. The engine also had major problems with reliability and driveability, the report added.
