2014 Italian Formula 1 Grand Prix - First free practice

07:47
Hello and welcome to live coverage of opening practice for the Italian Grand Prix!
07:48
It's a pleasant day at "Il tempio della velocita" (the temple of speed), albeit slightly cloudy
07:49
We arrive at Monza on the back of the season's most controversial moment
07:49
That was the clash between Mercedes duo Nico Rosberg and Lewis Hamilton
07:50
The pair appear to have moved on, with Rosberg apologising for his actions, but we're set for a fascinating weekend on and off the track...
07:51
As a reminder, Pirelli is supplying its Medium and Hard tyres this weekend
07:51
In terms of DRS, there are two zones in place, controlled by separate detection points
07:52
The first sits between Turns 7 and 8, with the detection just before Lesmo 2
07:52
The second comes along the main straight, with detection before Parabolica
07:53
There has also been a change at Parabolica, with tarmac run-off replacing gravel:
07:54
Remember, you can join in the discussion throughout the session
07:54
There is an interactive Facebook panel on the right-hand side of this page
07:54
And we can be found on Twitter via the @GPUpdate handle
07:55
We're just a few minutes away from FP1, with a few driver changes to mention
07:56
Giedo van der Garde is in for Adrian Sutil at Sauber, Daniel Juncadella for Sergio Perez at Force India, Charles Pic for Romain Grosjean at Lotus and Roberto Merhi – making his Formula 1 debut – for Kamui Kobayashi at Caterham
07:57
The regular drivers will be back in their cars a little later on
08:01
The green light comes on at the end of the pit lane and FP1 begins!
08:01
Plenty of cars heading out immediately, all on the Hard compound tyre
08:01
We don't expect to see the Medium rubber until this afternoon's session
08:02
All four stand-in drivers are in the group of early runners
08:02
Juncadella, importantly, will only be in for the first half an hour, following which teams must hand the extra set of Prime tyres back to supplier Pirelli
08:04
Hamilton completes a practice start before heading out for the first time
08:05
08:06
Plenty of flow-vis paint at the rear of the Force India
08:06
Teams are running special low-downforce packages here
08:07
Rosberg puts a couple of wheels over the new Parabolica run-off area
08:08
Perhaps the German is testing grip levels in the event of drifting wide?
08:13
Chilton and Merhi have the track to themselves at the moment
08:14
08:15
Chilton posts the first time of the weekend, lapping in 1:33.435
08:15
We're already seeing straight line speeds approaching 200mph
08:17
Replays show Chilton getting out of shape at the exit of Ascari
08:17
Kvyat, Merhi and Magnussen have joined Magnussen in posting times
08:18
Vergne takes over at the front with a time of 1:30.511
08:19
Magnussen is the first to break the 1m30s barrier (1:28.256)
08:19
Merhi is told that he is pressing the DRS button too early
08:19
He is also told to be less aggressive in terms of acceleration and braking
08:19
Plenty to learn for a rookie at a supremely fast circuit
08:20
Button makes it a McLaren 1-2 in the early stages
08:21
Massa and Rosberg now split the team-mates
08:22
Ricciardo is reporting that his DRS isn't working
08:22
Ericsson locks up and runs slightly wide at the first chicane
08:23
Magnussen has improved to 1:27.228 at the front of the field
08:26
Parabolica's new run-off is tested as Bottas locks up and takes to the tarmac
08:26
Button edges ahead of Magnussen with an improved time
08:28
The Mercedes duo now move to the fore, with Hamilton just ahead of Rosberg
08:28
Just seven thousandths of a second separating them after those latest laps...
08:28
Replays show Maldonado locking up and going straight on at the second chicane
08:29
"I feel like I only have front braking," Magnussen reports
08:29
That's a rather serious issue at any circuit, let alone Monza
08:30
All 22 drivers back in the pits as we pass the 30-minute mark
08:30
This is to allow teams to return to extra set of Hard tyres
08:32
Perez will reclaim his Force India cockpit from reserve Juncadella
08:35
08:38
Expect some more track action very shortly...
08:44
Merhi breaks the silence in his Caterham
08:44
Chilton and Raikkonen soon follow him
08:46
Merhi is weaving along the straights to get some extra heat into his tyres
08:46
Drivers are expecting a difficult task with the harder compounds here
08:47
Perez is now kitted up and ready to go after his early spell on the pit wall
08:48
Raikkonen has a big snap through Parabolica but keeps his car on track
08:50
Replays show Merhi having a moment at the Ascari chicane
08:51
Raikkonen improves to usurp Ferrari team-mate Alonso
08:52
Maldonado locks up, runs wide and clatters the kerbs at the first chicane
08:52
The Lotus driver appears to have avoided any car damage
08:53
Magnussen's head rest has worked its way loose
08:54
He makes it back to the pits for the issue to be fixed
08:54
Force India mechanics are changing the floor on Perez's car
08:55
It was secretly brought into the garage under a sheet earlier on
08:56
Merhi has moved ahead of Caterham team-mate Ericsson for P21
08:57
Alonso improves to reclaim fifth from Raikkonen
08:58
Kvyat has popped up to seventh, just ahead of Vettel
08:58
Maldonado has gone off at the first chicane again, taking to the escape road
08:59
The Lotus drivers are currently slower than the Marussias
08:59
Button jumps ahead of the Mercedes drivers with a 1:26.810
09:00
Vettel has displaced the Ferrari drivers with his latest run
09:00
But Alonso improves again to clear both Vettel and Magnussen
09:00
Ricciardo reports a loss of power over the radio
09:01
He is told to return to the pits as the car has an "issue"
09:03
Button sets new bests through the first two sectors, but backs off in the last split
09:04
Hamilton and Rosberg both improve, but stay second and third
09:07
Perez heads out for the first time, with just over 20 minutes left on the clock
09:08
Hamilton retakes P1 with a time of 1:26.547
09:09
Replays show Bottas drifting his way out of Ascari and through Parabolica
09:09
09:11
Hamilton lowers the FP1 benchmark to 1:26.187
09:11
That puts him six tenths clear of Button
09:13
Force India drivers Perez and Hulkenberg have broken into the top 10
09:19
Perez is now up to eighth, just ahead of Kvyat
09:20
Kvyat dips two wheels into the gravel coming out of the second chicane
09:23
Massa currently tops the speed trap on 346.4km/h (215.2mph)
09:25
Magnussen is told to be careful of high tyre surface temperatures exiting Turn 5
09:26
Merhi runs wide at the first chicane and takes to the escape road
09:26
Rosberg does a similar thing at the second chicane
09:27
Massa is another to misjudge his braking spot for Turn 1
09:28
Perez flies over the grass at the Ascari chicane
09:28
Mechanics will need to inspect the floor again after that one
09:29
Perez has another moment at the first chicane on his next lap
09:30
The chequered flag comes out, bringing the first session to an end
09:30
