Magnussen 'not worried' after third Haas power unit failure

Kevin Magnussen said he is "not worried" about the power unit failure that forced him to retire from the British Grand Prix.

It is the third power unit in a row for Haas and the fourth for Ferrari, after Nico Hulkenberg suffered a failure in FP2 at Canada and retired from Austrian Grand Prix.

Magnussen's car appeared to suffer a catastrophic engine failure when he pulled off after 31 laps at the Wellington Straight and fire started to appear from the rear of his car.

Despite the recently failures adding up at Haas, Magnussen was unconcerned when speaking to media including RacingNews365.com: "It's one of those things that is so much out of my control that I don't tend to worry about it.

"I offer my feedback if they [Ferrari] need it, but it's really up to them to run the engine and that's not something I can have an influence on."

Magnussen: Haas struggling to get into top ten

Magnussen was running in P14 before he retired, while Hulkenberg only managed to climb up to P13 having qualified higher up in P11.

While Haas had a more competitive race weekend in Austria, Magnussen says the team is still struggling to comfortably finish in the points.

"I think we were just trying to learn to get into top then. We would have needed some lucky Safety Car, which could have happened," he explained.

"But at the moment it's a little too hard to be in the top ten, we can't really get that without something external happening so we need to look at that next step."
