Red Bull keeping keen eye on engines as they watch "with interest"

Christian Horner insists Red Bull will wait until after the Canadian Grand Prix before making a decision on next years engine. Both Honda and Renault are expected to bring in upgrades.

Depending on whether either improves, Red Bull will swing one way or the other. It’s increasingly looking like Renault will get the pick with Honda struggling once more with reliability and pace.

Horner spoke to RaceFans about the issue confirming the team are waiting until Montreal.

“Potentially both engine suppliers are bringing an upgrade around Montreal, so we wait and see with interest,” said Horner.

In terms of development, time is running out for the Austrian team. Cyril Abiteboul, Renault’s boss, warns Red Bull of this factor coming into play.

“There is some urgency due to changes in the regulations. So if Red Bull wants our engines, they should let us know,” added Abiteboul.

Despite saying this he refused to put a deadline on the deal because “it’s not our style.”
