Marko believes there might be a bias towards Mercedes

Red Bull Racing motorsport advisor Dr. Helmut Marko thinks Formula 1 may be a little bias in the direction of champions Mercedes.

Mercedes have won seven times this season, including in Canada at the weekend, to maintain its 100% record thus far this campaign. Marko's Red Bull haven't been able to really compete with the Silver Arrows - with the team winning six constructors' and drivers' titles in a row.

"Let's put it this way: it's noticeable that the rule changes and decisions lately have always been good for Mercedes," Marko said to Auto Bild. "For example, Pirelli changed the tyre tread for 2019, so they wouldn't overheat, but last year only Mercedes had a problem with them.

When Marko was quizzed whether Mercedes were receiving some "special treatment" from Formula 1, he wouldn't deny the claim.

"I cannot prove that Mercedes got data earlier than us, but I cannot rule it out," Marko added. "We at Red Bull will look very closely at the future development of Formula 1 and there will also be discussions with Pirelli."
