Chief F1 writerFirst practice was an inconclusive session as a result of the different tyre choices and the constantly changing track surface at the Autodromo Hermanos Rodriguez, which started off extremely dusty and became quicker through the session as the circuit cleaned up.
But Mercedes did say that Nico Rosberg, who finished seventh, had not had any problems, and the two Mercedes drivers did set their times at similar points in the session, when the difference in track surface would have been minimal.

Spooky F1 drivers

Here's Daniel Ricciardo looking like a skeleton saddened by the fact he can't digest apples.

"We had an issue, with the rear brakes basically overheating," Red Bull team principal Christian Horner told Sky Sports.
"It was an energy recovery setting that we were trying that just got the rear brakes out of control. It damaged a couple of the electric looms and that's caused a bit of down time just to get that fixed."

Image source, Getty ImagesLewis Hamilton headed championship rival Nico Rosberg in first practice at the Mexican Grand Prix.
Hamilton was 0.759 seconds ahead of Rosberg, exactly the sort of display he needs at a race he really needs to win to keep his title hopes alive.
Rosberg, who leads by 26 points with 75 points available from three races, will be crowned champion on Sunday if he wins and Hamilton is 10th or lower.
Hamilton was fastest and Rosberg only seventh in an inconclusive session.

It's advantage Lewis Hamilton after first practice but, as we all know, it is very, very early days. Too early to guess how the weekend could pan out.
It's almost time for us to put things on hold for a couple of hours, with second practice at 20:00 BST.

As the session ends, Jenson Button reports feeling some pretty big vibrations. He's not kidding, it sounded like he was talking while sat on top of a washing machine.

The clouds have darkened considerably and Felipe Nasr reports some rain. His team initially are having none of it, saying: "Nothing on our radar" before quickly amending that with "rain reported Turn 16 thorough 17."
It looks to be only a few specks, though, nothing to really affect the drivers in the minute or so that remains.
