Hello and welcome to out live coverage of the day's action from Shanghai, kicking off with the third and final practice session ahead of Sunday's Chinese Grand Prix.

Plenty of action out there early on today, Kovalainen, Karthikeyan and Vergne having been first out.

And McLaren have confirmed that Hamilton has changed his gearbox for this session, meaning he will drop five places from where he qualifies today.

Before that, McLaren's Lewis Hamilton laid down a marker in first practice, banging in the quickest lap of the session after spending much of the morning in the garage.

Michael Schumacher showed the one-lap pace of the Mercedes with the quickest time of free practice two ahead yesterday.

Here we go then! Saturday practice is under way! This session will be an hour long.

The sun is out in Shanghai with the air temperature at 18 degrees, 22 degrees on the track.
