Qualifying is going to be an exciting prospect at the Yas Marina Circuit in Abu Dhabi, with Lewis Hamilton leading Nico Rosberg in both the practice sessions.
Both the drivers have admitted that they can go quicker and the German will hope that he can grab pole ahead of his teammate, giving him the best chance to snatch the title from the Briton.
Caterham have returned to the grid after financial issues restricted them from attending the last two Grand Prix in the United States and Brazil. Marussia still remain sidelined due to similar issues.

It was business as usual for the 2014 Constructors' Champions in FP1 and FP2, but unlike Brazil it was Hamilton leading his German teammate in both the sessions.
In FP1 the quickest Mercedes car was 1.7 seconds faster than the next best car, with Fernando Alonso, who is driving his last race for Ferrari.
However, in FP2 the rest of the field closed the gap and McLaren's Kevin Magnussen did his chances of retaining a seat for 2015 no harm by finishing just 0.782s off the Mercedes duo.
Alonso suffered electrical problems in just his third lap into FP2 and ended the session in the last place without setting competitive lap.
McLaren's Jenson Button lost out on much needed track time during both sessions with suspension and hydraulics issues. This could be the 2009 World Champions' last F1 qualifying session, with reports suggesting that the Briton is set to make way for double World Champion Alonso.
