Horner suspects higher engine modes at Mercedes: "Will be analysed"

Mercedes seems to be struggling with a problem. This is reflected in the engine of Valtteri Bottas, who is already on his sixth change of the season. Red Bull Racing team boss Christian Horner sees it all happening, but wants to keep the focus on his own team.

"Obviously they have some problems, but we are concentrating on our own performance and making the most of it this weekend," Horner told Sky Sports, who incidentally does not expect the grid penalty to be a major problem for Mercedes. "I think under normal circumstances they should be okay but you can never say never. The changes in Sochi put us in a reasonable position with Max," explained the team boss.

Horner suspects that his rivals have upped the engines. "Are they just running a higher engine mode or is it the system they are activating now? They'll be analysis of this after the session. It's not usual for them to run their engines as hard as they have."

"They're running them harder, there's a significant difference in straight line speed. It's not just down to the engine, they've dropped their rear height in Turkey. We've just got to make sure we get the best out of our car and I think there's more performance to come," Horner said.
