Renault’s Formula 1 teams have been given the all-clear to run their engines at full power in the Australian Grand Prix this weekend.
The French car manufacturer’s power units have had to run in a de-tuned specification so far to ensure reliability amid the teething troubles it suffered in pre-season testing.
But with software modifications to address its problems having delivered improvements on the dyno since the last test in Bahrain, Renault is now confident enough about the state of its equipment to allow its engines to run unleashed.
