Suzuka F1 track exposed Renault's lack of 'magic' power mode - Horner

Ricciardo Bottas Red Bull Mercedes F1 2017

Red Bull thinks that the combination of Suzuka's layout and the 2017-spec Formula 1 cars exposed its lack of a 'magic' engine mode from Renault more than usual.

The Milton Keynes-based team was surprised to be one second off the pace of Mercedes in the fight for grid positions, before Max Verstappen went on to threaten Lewis Hamilton for the race victory.

Red Bull boss Christian Horner thinks that a normal gap in qualifying, thanks to Mercedes' Q3 engine boost, was exacerbated because the Suzuka circuit was more power sensitive this year.

When asked why Red Bull was so much better in the race than in qualifying, Horner said: "I think we run the same modes [in the race] as we do in quali. It is a big difference.

"This circuit is quite sensitive given that such a large percentage is flat out, even with load-bearing corners.

"So what we seemed to find is, if we pick a corner like 130R, compared to our immediate competitors, even though that corner is flat-out, we never recover on the exit of the corner.

"We drop two tenths in that one corner. It's like Turn 3 in Barcelona, Turn 3 in Russia... those types of corner are particularly painful.

"And with this track now being a bigger percentage full-throttle, particularly towards the end of the first sector, accelerating out of the two Degners, out of the hairpin, around into the last sector... we see it's pretty painful there.

"We gave away in qualifying the best part of a second.

"The chassis has been strong all weekend, we can see from the GPS overlays that the chassis is right there.

"And obviously [Mercedes and Ferrari] can't run in the high power modes for that duration during the race."

Horner said that the nature of the corners at Suzuka meant that any power deficit was punished more than normal.

"Ultimately it's power, because as soon as you put a little bit of scrub, the engine isn't able to pull through," he said. "It's very sensitive to its acceleration at that point.

"Whereas if you've got the power, you can see that Mercedes and Ferrari are running more downforce than us.

"They're running a monkey seat, a deeper rear wing, and still their speed is extremely impressive."
