..... if he is referring to 2017 engines which I think he is, then this figure could be smaller this year as the F1 engines will start to converge.
So in race trim, we must be there or thereabouts. I don't think there will be a great difference between race mode and quali-mode this year due to 3 engine rule.
Reliability will be KING this year...... just my take in the whole picture.
I think for the team this year, they'd rather get a few excellent results than a lot of average results. Or putting it another way, I think they would be reasonably happy to sacrifice some unreliability for the chance of podiums or wins, even if it might cost them championship points overall. This is not to say that I think the team will take big risks with reliability either - after all, they wouldn't want to throw away the chance of podiums or wins due to poor reliability.
For the championship hopefuls, reliability will be key indeed.
