But interestingly they didn't require any tokens to make the fix since it was on reliability grounds.GPR-A wrote: Mercedes also had knocking problems at the beginning of last year, which didn't allowed them to run the PU at the same configuration as they were using in qualifying. They brought the fix in Canada and since then they started running closer to the quali mode in races. I don't think they attributed the fix to the fuel change.
Mercedes and Ferrari both sound as if they're pushing to the same kind of targets in terms of pressure, so will be interesting to see whether either or both push the envelope too far in order to beat the other and in process compromise reliability. They could potentially trip each other up in this way and others would benefit.
