@jee1: Nope, they get an extra set of tyres for the first half hour in FP1 and FP2.
Grosjean goes straight on at Turn 1.
@ABHISHEK: 6pm local time, that's 3pm GMT.
@JJA: I think they'll move quickly up to the midfield battle. Let's not forget Button predicted McLaren could have a car ready to win races by the end of 2015.
Nasr has moved into fifth with a 1:37.598.
@AdiosAyrton: I've been impressed so far, yes.
@JJA: I don't think so, no.
@ZAC: Current air temp 38 degrees C, 29 degrees C for track temp. Air temp should drop to around 28/29 later.
@JJA: It's certainly possible, with the engines still relatively new there is no real ceiling for the progress a new team can make. Plus, Mercedes and the others are likely to suffer the law of diminishing returns before Honda. So yes, they can keep making strides forward.
@mfbull: The race will be cooler than the race in China.
@gaurav2438: They can't move this session otherwise qualifying will be even later in the evening.
@VernonMitchell: 14 minutes left.
@jee1: Yes, he's only had three races. But then again, Red Bull is notorious for having limited patience with its drivers.
@chrisinnightimeperth: Honda should be praised for the fact it hasn't really tried to copy another manufacturer's PU. It could have just copied the successful Mercedes split turbo design but it didn't. I
@Prince: Because of the hotter temperatures in this session Mercedes isn't chasing headline times, which was the case in FP1.
Hulkenberg has bolted on a set of soft tyres and gone top with a 1:36.421.
Surprisingly, other teams have followed suit - Rosberg is out on the yellow-striped tyre as well. Didn't think we'd see these runs today.
@mandy: Hamilton beat Rosberg in a thrilling wheel-to-wheel battle, perhaps the best race of the season.
Perez, also with the soft tyre on, moves into third.
Rosberg now first with a 1:34.968. Massa into second with a 1:35.471.
Bottas moves into second. Both Ferraris out on softs too, so maybe the temperatures are cool enough that the teams can get some representative times in at the end of this session.
Purple first sector from Vettel.
Hamilton has moved into P1 with a 1:34.599, but let's see how Vettel can match up.
@Prince: The thing with noisy engines is that noise is wasted energy. The louder the engines, the less efficient you could argue they are. So I doubt we'll move back to throaty engines any time soon.
Vettel crosses just a tenth off Hamilton's headline time.
Well that was a nice busy spell I wasn't quite expecting.
Raikkonen has gone green in the first two sectors.
But the Finn can only finish fourth.
