Red Bull Formula 1 chief Christian Horner says he has never doubted the team has enjoyed parity ൲with the works Renault team for its power units, but believes the recent FIA technic🎐al directive is a positive step.

The FIA issued a technical directive to all 10 F1 teams in February stressing there must be parity between engines used by manufacturer teams and those it supplies to custom𓂃er ou🍸tfits on the grid.

Despite being a stringent critic of Renault in recent years over performance and reliability issues, Horner said that he has never been given reason to doubt t💮he French marque's engine supply has been equal to the one it us🦩es in-house.

Asked if it was good that the FIA was pushing for parity, Horner said: "I think so. We’ve never doubted that we’ve had parity w꧋ith Renault.

"We’ve had a different fuel and oil supplier, but we haven’t seen an♐ything concerning about the product that we’ve been supplied by Renault."

Re🦩nault F1 boss Cyril Abiteboul agreed with Horner, saying that it would allay any fears customers had about a lack of performance.

"I know it🤪's a constant concern from customer team𒁃s, and for very good reason, to make sure they are treated equally because that certainly should be the case," Abiteboul said.

"It certainly has been the way that we have been acting towards our customers in our 40 years of history of being an engine supplier in Formula 1🔥. That was always our intent, that has always been in the regulations. Now there is a clear directive in relation to that.

"But we also have to a🌄ccept that there will always be some small differences. Red Bull Racing is using a different petroleum partner. They will be using a different typꦆe of fuel and lube. That's creating some small discrepancies, but they know that and they've done their decision."

'GO AND SPEAK TO CLAIRE WILLIAMS'

While Horner stressed Red Bull never had any concerns about engine parity with Renault, he remained coy when asked if he belieꦫved other power unit suppliers were offering the same kind of guarantee.

"I don’t know. We’ve worked with theℱ same supplier for 10 years," Horner said.

"I’d go and speak to Claire Williams."

Williams Martini Racing deputy chief Claire Williams was asked about ꦏthe engine parity ruling not long after Horner's comments, and expressed her support for it, with the team working with reigning champion tea💃m Mercedes since 2014.

"It is a regulation that says that ဣwe have everything that the works team has," Williams said.

"We are happy with that."
