Hello and welcome to ESPN's coverage of third and final practice ahead of this weekend's Abu Dhabi Grand Prix.
This afternoon's one-hour session is the final chance the teams have to tweak their set-up ahead of qualifying and the race. We expect a tight battle for pole between Hamilton and Rosberg later, the margins between them over one lap are so fine.
Another oddity about this session is that the temperature is much hotter than it will be in qualifying or the race, given that both are evening sessions. For that reason, FP2 had added importance yesterday and Mercedes was some seven tenths clear of anyone else.
@mfbull: This might be Button's last grand prix weekend, so there's that.
@Pronny: Hulkenberg said after FP2 he thought it would be lucky for Force India to get into Q3 today.
That last tweet is something I'm curious about. Vandoorne has been superb this season in GP2. While it makes sense for him to stay in that series for another season and challenge for the title, I imagine he's made a hard decision even more difficult in Woking.
The clock is ticking and Maldonado is the first man to make his way out of the pit lane. Mind the walls, Pastor.
Raikkonen and Bottas among the first cars to head straight out on track.
As ever with practice sessions, these drivers will complete their installation laps in the opening minutes and return to the pits.
@mfbull: There's all sorts of ways you could read into it. Perhaps it is waiting to see who wins the world drivers' championship... Hamilton is contracted for 2015 at Mercedes but not beyond.
I do not think Hamilton would leave Mercedes in 2016 even if he lost this year's title, but it's a theory.
@Pronny: If anything degradation will be worse in this session than it will in the race, because of the hotter mid-afternoon temperatures in FP3.
Rosberg out on track early on.
Soft tyres all around at the moment. Expect to see some qualifying simulations on the super soft tyre later on.
@@radical: Mercedes, Hamilton especially, looked pretty supreme in the longer runs. Hard to tell from Williams as it had such limited running in FP1 with those bodywork issues.
@Mohan: The big one is that the noses will change, so no more of the horrible Lotus tusk nose any more. They should look more like F1 noses next year.
@Prithvi: As I said, I don't think Hamilton would leave Mercedes. But the delay suggests to me Dennis is keeping all his options open in that regard.
Alonso the early pace-setter, a 1:44.581 the benchmark.
@Harish: No,sorry to be unclear. McLaren has signed Alonso for next year - it hasn't been confirmed but it's widely accepted in the paddock. The main delay is over his team-mate for next year. Alonso has no worries for next year.
@TheeUnderBrake: Good luck to any new team joining at the moment.... I'm curious to see how they do though. Unlike some other recent ventures, it's not just being bankrolled by some millionaire looking for F1 exposure (Caterham - Fernandes) but actual racers from NASCAR.
@AnderKaver: No announcements, no.
@Heman: Nope, results from the test were kept pretty guarded overall.
