Red Bull team principal Christian Horner has admitted that he'll be keeping a close eye on both Renault and Honda engines, as Red Bull hasn't made any commitments yet when it comes to engine partners for the coming years.
Red Bull has been partners for a long time with Renault and the teams have won championships together, but there have been rumblings of Red Bull switching sides and going to Honda in 2019.
Red Bull's development team Toro Rosso is currently with Honda, which is a good thing for the Bulls themselves, as they can keep a close look before making a decision.
“Hopefully around Montreal time, there’s a next engine introduction,” Horner predicted.
“We’re hoping from a performance increase.
“Potentially both engine suppliers are bringing an upgrade around Montreal so we wait and see with interest.”
Red Bull has been holding conversations with Honda since Azerbaijan, according to sources. Renault gave Red Bull the obligation of choosing an engine partner by the end of May, but Horner already dismissed that idea.
“There won’t be a decision in May.”
