@MarieClaude: Possibly. It certainly doesn't sound like any other engine in F1!
@RohanMehta: We usually see Williams lower down in the pecking order on Friday practices and then pick up the pace on Saturday morning. I'd say they will be much higher up in qualifying as they usually focus on other things in practice.
@vinay: Well, they're ninth and 11th so far on the supersoft tyres, both very good drivers. Traction has never been a huge issue on the VJM08. Maybe we'll see one of those boys get into Q3.
@Phoenix: I haven't yet, but I plan to. Would be curious to know what people's thoughts are?
Great onboard with Alonso as he goes up the hill. I've never forget thesite of him binning the car there in 2010 FP3, which cost him the race win.
@rockedin123: The damage wasn't enough to stop him competing in qualifying but the missed running and data will be a huge blow.
Ericsson has a huge lock up and slides into the runoff area at Ste Devote.
@RTCB: They've both only used one set each in this session, I believe.
Ricciardo has moved above Rosberg with a 1:17.139. Rosberg on a supersoft lap though and has gone purple in the middle sector.
That's much better from Rosberg as he moves to within 0.065s of Hamilton.
@BE: All four drivers had moments in the season where they lost points they didn't need to. Webber in Korea, Hamilton in Monza and Singapore, Alonso in Monaco, Vettel in Hungary and Belgium. Was a great season full of twists and turns.
Not a lot of changes on the timing screens now as we enter the final six minutes.
@papalicius: I think it's harsh to judge their abilities against each other on one season. The consensus from people who were at McLaren at the time was that Alonso was quicker but let the drama and politics consume him a bit - one issue is he's always been very poorly advised by those around him. Without Hungary and his blackmail threat I think his position in the team would have been a lot stronger and he would have won the championship.
Vettel goes P1 with a 1:16.143, half a second quicker than Hamilton. That track is really evolving but that has raised a few eyebrows.
@aguickdrag_on: Well, they'll have general data that both sets of engineers use, yes. But it's not like he's stealing Vettel's data, or anything.
Rosberg jumps above Hamilton with his latest time but can't topple Vettel, he's two tenths down. Hamilton appears to be finding himself some track space for a late run now.
Perez having a big moment through the final corner, after having to dive around Vettel's slow-moving Ferrari at Rascasse.
Hamilton's lap didn't look spectacular but he has to bail out through the final sector as he hits numerous cars backing each other up.
Sainz switches places with Raikkonen to finish fifth. Toro Rosso still looking handy.
"Something's not right with the car," Hamilton complains. His race engineer tells him the pressures were not right on his last run. Potential issues before qualifying?
The drivers make their way to the grid for practice starts. That's all we have for you this morning - thanks as always for joining and please do come back this afternoon for the all-important qualifying session.
