@sat: Nope, Nasr and Wolff will be done for the day.
I'll be sure to ask them later! As for Kimi's time, as ever with testing, it's impossible to make an accurate reading because there are a lot of things we don't know. I'm only reporting the fact that it is quicker than Hamilton's pole lap from last year because it is, so read into it what you like!
@MarcosLeitão: Hard to know. Both teams are apparently reviewing video of what happened but until we hear from the teams (and Wolff and Nasr) we won't know for sure. Though, I can't remember an F1 driver being keen to own up for a mistake before....
Wehrlein continues to accumulate miles for Mercedes in Hamilton's stead. The German is racking up quite a personal haul, he's done 51 laps today in two different cars.
Anyone who needs proof the headline times might be misleading - Perez is currently second in a 2014 car.
The information trickling through the paddock is clear on what happened with Wolff/Nasr (Wolff's front left clipping Nasr's left rear). It isn't so clear on who is to blame as of yet.
@Nimitz: I doubt the car is underweight, although it may be on light fuel. However, Hamilton's pole time last year was on low fuel too.
@MikeInDenmark: My mistake - Wolff's front left clipped Nasr's rear right
@Nimitz: Nope, cars qualify on low fuel and then refuel for the race.
@MB: As I said, it's correct that Hamilton was on low fuel when he did his qualifying lap last year. But the Pirelli tyres are not two seconds quicker than last year's compound, they are in fact very similar compounds. The only difference is that they are currently in the wrong operating temperatures. However, I agree - as I said before - that it is very unlikely the Ferrari is underweight.
Ricciardo has just completed his fifth lap in a row - this is the longest stint I can remember him doing all day.
@mfbull: How much they weight often depends on whether ballast is added to the front, but they are reasonably heavy. The FIA deflection tests put them under a load of 100kg but the loads when on track are much higher.
@Canuck: That's true, but what advantage is there to running underweight? The teams are typically looking for relevant data to help prepare the cars for racing.
Max Verstappen is also back out on track after a rather sizeable delay.
@bongc888: It was a faulty seal that caused the issue.
@hacke: Ah, an MGU-K is the Motor Generator Unit - Kinetic. It is part of the Energy Recovery System, which harvests energy from the rear axle under braking. As the car is off throttle, the MGU-K puts resistance on the rear axle - acting like a brake but more importantly gathering energy. That kinetic energy is then stored in a battery and used to boost the power of the power unit over the course of the lap.
@Tirthankar: We didn't have a pre-season test here last year, but the best time a Force India set at this circuit was a 1:27.685. I'm not sure which tyre compound Perez was on for his lap, but the gap will also be down to the development that went into the VJM07 between the Spanish Grand Prix and the end of last season.
@JDC: Hamilton's pole time was a 1:25.232 but the fastest time in a 2014 car was set by Maldonado at the post-season test with a 1:24.871. Given the intense development over the winter, I think we can expect times in the 1:23s this week. The best time in a 2013 car here in winter testing was a 1:20.130, but that was with exhaust blowing and faster tyres.
