Renault managing director Cyril Abiteboul has hit back at Adrian Newey’s claims that the french firm’s engine is to blame for Red Bull’s tough start to the season.
Red Bull struggled at the 2015 season opener in Australia, with Daniel Ricciardo coming home a lapped sixth, prompting team boss Christian Horner to criticise long-time engine partner Renault, revealing its 2015 power unit is 100bhp down on those of its rivals.
Technical guru Newey added that there was no light at the end of the tunnel for Renault, but Abiteboul has rubbished the claims, suggesting the Red Bull chassis is also not up to scratch.
“Yes, it’s difficult to have a partner who lies,” Abiteboul told French publication Auto Hebdo.
“Adrian is a charming man and an engineer without parallel, but he’s spent his life criticising engine partners. He’s too old to change his ways.”
Abiteboul is adamant that both Renault and Red Bull need to work together to recover lost ground, and is confident of an improved showing in Malaysia this weekend.
“Our figures have shown that the laptime deficit between Red Bull and Mercedes in Melbourne was equally split between driveability issues, engine performance and chassis performance,” he said in a Renault press release on Tuesday.
“It’s therefore the overall package that needs some help and we have been working with the team to move forward.
“We’ve been particularly aggressive in development and we should see the results a lot more clearly in Malaysia, particularly since we have had the opportunity to refine the PU using the data from Australia.
“Work is still ongoing but even now we are in a completely different place to where we finished Melbourne.”
