Ric was 4/10ths down at Monaco in a qualifying skewed by Rosberg's incident in the dying moments of the session.
Vettel was 6/10ths down.
Your suggestion Ricciardo was cruising in the race intimates that relative to the Mercs he could've gone quicker.
Yet we know 4/10ths was the original deficit, which could've been greater had Hamilton completed his final effort in Qualifying.
We also know Kimi Raikkonen set the fastest lap on lap 75, which can directly verify that if Ricciardo was cruising in the initial phase of the race, Mercedes too had been cruising toward the end by virtue of the Ferrari not being anywhere near as fast as the W05.
We also know that Hamilton could not see out his left eye. Around Monaco, that is nigh on lethal.
Rosberg knew Hamilton could not catch him in such circumstances, and held station.
Ricciardo had all to gain so was racing a one-eyed Hamilton to the flag.
If we look at Hungary, another of the less relevant tracks to engine power, we see that Mercedes had a gap of 7/10ths to Red Bull in qualifying.
If it all boiled down to the engine, all Mercedes powered teams would be in contention. Yet McLaren and Force India don't trouble Red Bull.
The gap in Canada qualifying to Red bull was 7/10ths too....what happened to all this engine power in Canada if the in Hungary the car maintained the gap?
At some point's this year, Mercedes have been around 1.7 to 2 seconds seconds quicker than McLaren in race and qualifying.
This in spite of them using the same PU.
If you look at this from any logical perspective, you'd conclude from the statistics available, that Mercedes W05 has chassis to match anything out there at present.
And today we have Lowe stating it clearly.
These cars are about system performance, not individual elements.
It's about how you put it all together. It's the power unit, the efficiency of the power unit, the aerodynamics, and the manner in which they're all put together. It's the collective efficiency of that package from a power, aero and suspension point of view, as well as a weight point of view. Our car is very quick. There are other cars running that power unit that aren't as quick, so it's a whole system.
