Daniel Ricciardo says Renault have a “pretty big” upgrade package for this weekend’s Spanish Grand Prix, including a reliability update for its power unit.
A further reliability tweak is coming in a new engine specification this weekend, according to Ricciardo.
Cyril Abiteboul: “Some materials, I know what they are but I don’t know how much I can obviously say, but some materials have changed to help reliability.”
Ricciardo hopes this means the team will be able to shift its focus back to improving the performance of its E-Tech 19 power unit.
Ferrari has also brought a new power unit to this weekend’s race.
