Engine swap

Daniel Ricciardo says that he struggled to get as much from Renault’s upgraded power unit as his team-mate Max Verstappen. Renault brought a new-spec unit for all six of its cars in Canada, but Ricciardo trailed Verstappen in both qualifying and the race. He told Sky: “We had the upgrade and my car struggled more with the driveability, the calibration. It could have been better, let’s say that. I was just struggling to keep the tyres under control with that driveability. I would say it explains some of the inconsistency. But also, Max was driving really well all weekend, so I won’t take that away from him.”

Aston are confident rules will be adjusted for Vantage
