Renault will prioritise the reliability of its power unit above all else in 2018 after admitting it rushed through a series of performance upgrades this season.
In the back of a Red Bull, Renault power won three of 2017's 20 races but the French manufacturer was down on power throughout the season compared to rivals Ferrari and Mercedes. Towards the end of the year, its engines were also hit by a series of reliability issues that resulted in a number of retirements and grid penalties for its customers at the final rounds.
The pressure to perform will increase next year as McLaren joins Red Bull and the works Renault team in using the engines from Viry-Chatillon, but Renault Sport F1 managing director Cyril Abiteboul is confident his outfit has learned its lessons from 2018.
