Meanwhile, replays show the pit entry bollard skimming across the track after Valtteri Bottas' late decision to head in sees him drive his Williams into it. Out scampers a marshal to recover the bollard while the red flag is out.

Jenson Button is back out on the medium tyre. He has some catching up to do on the rest of the field, having spent much of this session back in the McLaren garage.

It may not be high-tech, but cutting holes into the car appears to be doing the business as Red Bull muscle in between the two Mercedes on the timesheet.
Daniil Kvyat goes second fastest - just 0.2s off Nico Rosberg's time - with Daniel Ricciardo third fastest.

We saw Nico Rosberg suffer from the effect high altitude has on the brakes in first practice, with the thin air making it harder to keep them cool and Mercedes blast cool air into the wheels as soon as Rosberg and Hamilton return to the pits in an effort to keep the temperatures down.
Meanwhile, Red Bull are combating the overheating by cutting some holes in their cars.
Quite amazing to think such a basic method is utilised in then high-tech world of F1...

Encouraging stuff for McLaren with Fernando Alonso sixth fastest on his soft tyre run, just two tenths of a second down on Valtteri Bottas' best effort in the Williams.
Still no lap-time for Jenson Button, however, who has managed just two exploratory laps in this session.

Andrew Benson
Chief F1 writer"The innovative ‘stadium’ section has drawn praise, even if the very low-grip new surface was not massively popular with the drivers in first practice. The parkland setting makes the location look quite attractive on television - the circuit snakes through verdant surroundings with a mountainous backdrop, with even the famous Popocatepetl volcano visible to the south-east - belying the traffic chaos and urban sprawl outside."

That stadium section captures the atmosphere superbly as each time a car weaves its way through that twisting section of the circuit you can hear the loud cheers from the fans in the stands.

Lewis Hamilton and Nico Rosberg have joined the yellow-walled tyre party and they immediately brings about a sense of familiarity to practice by going first and second fastest respectively. Hamilton went top with a 1:21.961, with Rosberg three tenths of a second slower.

Seven drivers have got the soft tyres bolted on, Carlos Sainz and Romain Grosjean among them included and they are currently second and third fastest respectively.
