Still a dozen cars on the circuit as we enter the final minute…
And Massa pits. That could be that.
Massa out on track, currently P6. Some encouragement for Ferrari.
Five minutes remain in the session. The order – Hamilton, Rosberg, Webber, Sutil, Raikkonen.
Grosjean also has a new front wing fitted to his Lotus. Currently P11.
Now Hamilton locks up into Turn 1. A lot of drivers having problems there.
Looking unlikely that anyone will better Hamilton’s time now. Gutierrez reporting a lot of vibrations, probably as a result of the lock up.
@clubforce Both driver head back on track for the last 11 minutes of this FP1 session. Programme proceeding according to plan
Vettel improves his time and goes P8, Raikkonen is up to P5 and he’s coming in for a front wing change.
Hamilton and Rosberg still lead the way. Webber now back in third.
Every runner has used the medium tyre so far so we’ll probably see the softer compound this afternoon.
A wobble for Raikkonen as he runs very wide at Turn 11 kicking up gravel and sparks.
And Hamilton and Rosberg also head back out so it could be an interesting end to the session.
Vettel back out on the circuit so let’s see if he can improve.
Vergne also locks up into Turn 1. A lot of drivers struggling with that corner early on.
Still Hamilton and Rosberg remain in the pits but it’s been a good session for Mercedes so far.
@InsideFerrari @alo_oficial is foced in the pits as the problem on his car continues. His session is over.
Indeed Alonso does climb out of his car and his helmet is off. Bad start for Ferrari.
Huge lock up for Gutierrez at Turn 1 as Chilton sets a time.
Looks like Alonso is preparing to get out of his car and that could be that for the Spaniard!
There is a problem with Alonso’s ECU. Only he and Chilton have yet to set a time.
Mechanics still working on Alonso’s car and there’s also work being undertaken on the back of Vettel’s Red Bull.
Adrian Sutil jumps to P3 with a 1:31.754.
Hamilton and Rosberg have completed more laps than anyone else but are now sitting in the garage.
Troubles for some drivers. Ricciardo misses the apex at Turn 1 and Button bottoming out into the same section.
Hamilton’s time is already quicker than the quickest FP1 time of 2011.
So with half an hour remaining in FP1, Hamilton leads from Rosberg, Raikkonen, Webber and Sutil.
There is a problem with the DRS system and teams have informed their drivers of the issue.
@Lotus_F1Team Driver feedback time: Understeer, oversteer, wombling free...
Rosberg improves his time but Hamilton still the quickest man out there. He improves to a 1:31.754.
Raikkonen is the only non-Mercedes to lap in the 1:32s. He’s currently third quickest.
@clubforce Programme going to plan this morning. Both cars will be out on mediums shortly for more laps. #FeelTheForce
Massa’s car is now being worked on. Worrying early signs for Ferrari.
More on the FIA banning tyre swapping for the German Grand Prix.
The bad news for Alonso is that the electrical glitch has again reared its ugly head. Luckily he made it back this time.
The Mercedes already looks strong. Its problems so far have been with rear tyre wear but this is a cooler circuit.
Lewis Hamilton the new fastest man on the circuit. A decent 1:32.349.
Raikkonen goes second quickest with a 1:32.965 as Alonso returns to the pits. Still to set a time.
And indeed Rosberg does go quickest with a 1:32.552.
Rosberg going quickly although the Mercedes looks a little nervous. The new nose cone on both cars.
Both Red Bulls at the top of the time charts as Vettel goes second quickest with a 1:33.505.
Hulkenberg runs wide into the final corner. It’s his first GP at the Nurburgring.
Grosjean locks up and runs slightly wide into Turn 10. No real dramas.
Massa goes P4. Webber still quickest from Button and Grosjean.
Mark Webber, the 2011 pole sitter, goes quickest with a 1:33.047.
@InsideFerrari @Felipe1Massa jumps back in the car and out he goes to start his first run on Medium tyres. Set-up work and aero mappings on the job list.
And Button improves further with a 1:33.545s. Alonso looks like he’s ready to go out again.
Action aplenty now, lots of cars on the circuit. Button still quickest from Perez and Grosjean.
Sparks fly from the front wing of Grosjean’s Lotus. He goes second quickest.
Button goes quicker still with a 1:33.642.
As a reference, the 2011 pole time was set by Mark Webber with a 1:30.079.
McLaren team-mate Sergio Perez is second quickest with a 1:36.120.
Button’s lap set on the medium compound Pirellis.
Button continues to press and clocks a 1:34.342.
Hoorah! Button has set a time. He crosses the line in 1:39.929.
Christian Horner: “I hope the situation has been sorted as more than anything, safety is of paramount importance.”
Christian Horner thinks that Pirelli have addressed the concerns of last weekend and doesn’t forecast any problems.
It’s the usual FP1 problem with the big hitters biding their time as the other cars clean up the track. Button goes out.
With Hamilton still the only driver to set a time, albeit a slow one, teams are treading carefully so far. Ricciardo prepares to go out.
@clubforce The 'ring is such a great track. Lots of difficult turns mixed with exhilarating high-speed corners. A pleasure to watch Paul out on track.
With relatively low track temperatures expected, Ferrari and Lotus are predicted to struggle more this weekend.
The Williams team are officially celebrating their 600th grand prix this weekend with a big ‘600’ stamped on the side of the car.
Both cars on the medium compound.
Still Hamilton the only man to set a time. Only Di Resta and Chilton out.
Valtteri Bottas: “It’s nice that Pirelli and the FIA have reacted so quickly. I hope the problem is resolved and I don’t have any problem with the car.”
Mercedes appear to be running a new nose with the Lotus cars running their innovative passive DRS system.
A lot of cars opting to run the medium compound white banded tyres early on.
Alonso has finally made it back to the pits. He’s smiling, which is fairly unusual after that disappointment. Reports are it may be an electrical failure.
Jean-Eric Vergne breaks the silence and comes back out again.
Sebastian Vettel is searching for his first German GP victory this weekend. Lewis Hamilton won last time out at the Nurburgring.
@InsideFerrari @alo_oficial forced to park his F138 alongside the track for a problem (still to be verified) on his installation lap.
Replays showing smoke from the left front of Hamilton’s Mercedes. Cars back in the pits after the initial installation laps.
Lewis Hamilton sets the first time of the weekend. A slow 2:16.935.
@MyCaterhamF1 "The track is quite dusty, but ok" reports
The car is on the infield section so they may be able to get it quickly back to the pits and rectify the issue.
Still nobody has set a time as marshals surround the stricken Ferrari.
A disaster for Alonso. He’s out of the car and this could be the end of his session too.
Fernando Alonso has lost all drive and stopped on the circuit coming out of Turn 5. Yellow flags out.
Pirelli and the FIA have set tyre pressures at this race to prevent the tyre failures we saw at Silverstone.
There is one driver change in FP1. Rodolfo Gonzalez is in for Jules Bianchi at Marussia.
A gaggle of cars flood out onto the circuit for their installation laps. Medium and soft tyres in operation.
The pit lane is open and one of the most crucial practice sessions of the season is underway. Let’s hope the new Kevlar belted Pirelli tyres hold together! It's dry but cloudy.
Five minutes until the pit lane opens. Check out our big German Grand Prix preview.
@MyCaterhamF1: Weather update (they do like to keep us on our toes eh!) Low cloud ./ grey skies this morning, minimal shower risk (10 - 120&) & very mild.
