So far, the weather has played a huge part in the practice sessions, leaving the true order of things something of an unknown. Qualifying position isn't the be all and end all in Brazil like it is at some other circuits, but as the final race of the year, there's pride at stake. Who will get the last pole position of 2013? Can Mark Webber set himself up for a good start at last? Can Heikki improve on his qualifying in the US? All these questions and more will be answered over the next few hours.
