2017 all vs Merc:
2017 all vs Mclaren
2017 Works teams vs Mclaren
Not sure it is as insightful as the audio analysis, but it is a lot quicker and easier to do :p
Of note is that the first four races were particularly bad for Mclaren last year, likely due to the difficult preseason testing. As such the comparison between this years performance and last years for the first four races needs to be carefully considered.
However I think its fair to say that from Russia / Spa last year they were racing against Renault and the same is pretty much true this year. Therefore the Renault and Honda PUs were and are pretty much even.
