The Lotus duo look reasonably placed if they can get third row or higher tomorrow. The strength will be their race pace.
Some teams conducting pit stop practice at the end of the session but most teams still out.
As the session draws to a close it’s Vettel from Webber, Grosjean, Massa and that man Vergne. Should end that way.
It’s been an encouraging session for Jean-Eric Vergne. He’s fifth quickest with Ricciardo 16th.
Perez told to push for the remaining four laps.
Work continues on Vettel’s car and the floor is being removed.

Christian Horner says he is unsure of the cause of the puncture.
Hamilton locks up towards Les Combes and throws up some sparks as he hops over the kerbing.

Replays seem to confirm that Vettel’s problem occurred in the same spot as Van der Garde went off and it happened over the kerbing.
Vettel has left the garage so that seems to be session over.
Vettel climbs from his red Bull in the pits. Late drama in this session when nothing seemed to be happening!
A very strange situation, the back end just left him out of Turn 15.
Giedo van de Garde has slewed off the track and into the barriers. The yellow flags are out. He's okay.
That was Vettel’s 11th lap on the medium tyre.
It doesn’t look like a dramatic delamination but a slow uncture.
Well drama here! Vettel has had a right rear tyre blow out. Vettel says it’s a slow puncture so it wasn’t like at Silverstone.
Hamilton: ‘Is my dashboard telling me the right time because the car is all over the place’.
@clubforce: Paul Di Resta back on track on mediums
Most of the cars out on the circuit conducting long fuel runs. Alonso not consistently fast on the mediums.
@Marussia_F1Team: Jules is P21 and out on circuit. Max's return to the track delayed by a steering rack change
Chilton has changed his steering rack.
Hamilton back on the hard tyre after tinkering with his car balance.
This could be a low fuel run for Alonso so we’ll get a measure of his true pace.
Out comes Alonso on the medium compound!
More problems at the Bus Stop as Rosberg outbrakes himself. Hamilton not happy with the set up of his Mercedes.
@Lotus_F1Team: Back out on mediums Mr Raikkonen
Alonso is having work done to the rear of his Ferrari. Still yet to try the medium compound.
With most cars on the longer runs, the times are unlikely to be bettered.
Webber is over six seconds slower on his tenth lap on the hard tyres than on the mediums.
Vettel pushing hard on his heavy fuel run. He runs wide at Rivage and kicks up some gravel.
Massa struggling for grip out of the Bus Stop but he still goes fourth fastest.
Vettel and Rosberg are on heavy fuel long runs.
A good lap from Sutil on the mediums. He goes P8.
Hamilton has completed four laps on the medium tyre but is still off the pace relative to the competition.
Interestingly, Ferrari have not used the medium compound on either car yet.
Perez looking better than Button. He goes fifth ahead of Rosberg.
Vettel heads the times from Webber, Grosjean, Raikkonen and Rosberg.
Button is slow through sector 2 on the mediums, over a second off the pace. Worrying for McLaren.
Hamilton only ninth on the mediums.
Horner predicts the long runs to start in ten to 15 minutes. Webber back out.
Christian Horner confirms that his drivers are on different strategies.
Hamilton out on the medium tyre so it will be interesting to see where he is relative to the Red Bulls.
Raikkonen goes fourth quickest. He has won four times around Spa.
Raikkonen out on the mediums. Alonso told to run three laps on the hard tyre.
Grosjean is third quickest with a 1:50.440. Alonso back out.
Massa: ‘The car is having oversteer everywhere. Everywhere!’
A lot of snap oversteer for Massa on the exit to turn 8.
And Vettel reclaims his top spot with a 1:49.331s. Red Bull looking good at the moment.
Alonso is fourth quickest but he has only completed five laps. Rosberg goes third quickest on the medium tyre.
Now Vettel is on the medium tyres.
He doesn’t better his time.
Webber has been told to push for one more timed lap.
@McLarenF1: 30m gone in Belgian Grand Prix FP2. First runs completed for most cars. Jenson is P8, Checo P10. VET leads with 1:50.555.
Still some way off last year’s pole time so it suggests they may be running heavier fuel loads.
And he’s comfortably quickest as expected with a 1:49.390.
A fastest first sector for Webber. He’s on it…
Webber also out on the mediums.
Vettel still the fastest man on the circuit from Massa, Alonso, Hamilton and Webber.
Raikkonen returns to the pits.
Grosjean also out on the mediums.
@MyCaterhamF1: RT @charlie_whiting: Race Control: Teams may only have 1 car in the bus stop runoff at a time. cc @MyCaterhamF1>>> yes, noted....
And his time puts him seventh on the sheets.
Ricciardo is out again and he’s on the white medium compound. This will be interesting.
Felipe Massa preparing to go back out again.
A lot of the cars back in the pits for evaluation. Hamilton, Grosjean and Massa the only ones out. Lewis has a moment at turn 9 too.
Grosjean also has a little moment into turn 9. Not an easy circuit Spa in any conditions.
Button complaining that the oversteer at the top of Eau Rough is ‘pretty bad’.
Vettel improves further to a 1:50.555s.
Hamilton has just gone out.
A little moment for Perez between turns 12 and 13. Nothing serious.
And Vettel goes to the top of the timesheets with a 1:50.867s.
A lot of Flo Vis paint being used by the teams. It’s a way of seeing what the airflow is doing over the car.
Masa userps Webber at the top of the times. Alonso third.
All the cars out on the track, it’s already a busy session.
Mark Webber the fastest man on the circuit with a 1:51.317.
Vettel comes up to the Caterhams and Charles Pic doesn’t appear to see him into the Bus Stop as he veers back into him. Vettel not happy.
The lead time is swapping all the time. It will be a while before we get an accurate reading.
Gutierrez sets the first time. A 1:52.558s. Ricciardo goes quicker.
Strange that Lotus would do that. It must mean it isn’t working.
Mercedes have their new rear wing on for this session and Lotus have taken their passive DRS off.
@OfficialSF1Team: The sun is out for FP2 air 21C track 28C no rain expected for the session.
A flood of cars have followed the Hulk out onto the circuit. Expect the lap times to tumble.
Nico Hulkenberg is the first car out and he’s on the hard tyre.
The pit lane is open and we’re underway again.
The sun is beaming down now and it’s blue skies all round. Great stuff. Pit lane opens in five minutes.
Even the wettest sectors, namely sectors 1 and 3, are relatively dry now. We may see the medium tyre for the fist time.
The good news is that the track has been drying out further so teams will get some significant running this afternoon and we may get a truer reflection of where we stand for the rest of the weekend.
Fernando Alonso topped the timesheets after a wet opening practice session. The circuit did dry towards the end of the session and his time was set on the hard compound tyre.
Hello and welcome back to the second free practice session for the Belgian Grand Prix. The pit lane opens at 12.00 GMT, 13.00 BST.
