Lewis Hamilton :
We tried our best to go long today and were hoping that we might benefit from a safety car or a VSC. Unfortunately it never came to us, and we ended up finishing slightly further back than we started. It was worth trying something different though. We gave it everything we had, and that was likely the best result we could get today given how the race played out.

The car today was pretty good in the medium and low-speed corners, but we were losing out in the high-speed. These next few races will be tricky but we will be putting in a great deal of effort to improve as much as we can. I know everyone at the factory will be getting their heads down and working as hard as they can.
