There will be plenty of people out there who will disagree with this analysis of the competitive order based on pre-season testing. And I hope I am wrong.
To make any sense out of these two pre-season tests is pretty difficult. But over the days a trend emerges, and that trend points to Mercedes having once again done an exceptional job.
You would have to tick all the boxes: performance, reliability and tyre degradation all look to be under control with the W09. The only little fly in the ointment might just be that Mercedes won't be as good as others when push comes to shove using softer tyres for qualifying.
