Hello and welcome to live coverage of opening practice for the German Grand Prix!
07:50
It's a glorious day at Hockenheim, with the sun out in force
07:51
Air and track temperatures are currently sitting at 25°C and 35°C respectively
07:52
Expect those to rise considerably as the day progresses
07:52
Sunday is the only question mark at present, with some showers being forecasted
07:53
As a reminder, Pirelli has brought its Super Soft (Red) and Soft (Yellow) tyres to Germany
07:53
In terms of DRS, there are two zones in place for the weekend's action
07:54
Controlled by separate detection points, the first comes between Turns 1 and 2, with the second following along the curving Parabolika, between Turns 4 and 6
07:54
There are two driver changes for this morning's first session
07:56
Susie Wolff, hoping for a much smoother run than Silverstone, is in for Valtteri Bottas at Williams, with Giedo van der Garde replacing Esteban Gutierrez at Sauber
08:00
The green flag comes on at the end of the pit lane and FP1 is underway!
08:01
Wolff is the first driver out for Williams
08:01
Wolff's car is moving extremely slowly on her installation lap. Could it be another problem?
08:03
She's crawling back to the pits while a host of cars move past on their install laps
08:03
Replays show some smoke coming from the rear of Chilton's Marussia
08:05
Wolff has finally brought the Williams back to the garage
08:05
It looks as though she was stuck in first gear for the entire lap
08:06
All 22 drivers have been out on track for exploratory laps
08:08
08:10
Wolff's car is up on jacks, with mechanics already hard at work
08:10
A brief lull as the drivers prepare for their first proper runs of the day
08:12

08:13

08:21

08:23

08:24
Hamilton had gone fastest of all through the first sector, but he locked up at the hairpin
08:25
Rosberg moves to the front with a 1:20.337
08:25
Vettel goes fourth, just behind the two McLarens
08:26
Alonso is now fifth, from Ricciardo and Vergne
08:27
Vettel edges 0.042s clear of Rosberg
08:29
Replays show Hamilton locking up and running wide at Turn 8
08:30
We've hit 30 minutes, meaning the extra set of Prime tyres much be handed back
08:31
This sparks another quiet phase
08:32
Ferrari reports that Raikkonen has a technical problem
08:32
We will bring to more on that as and when we find out
08:34
08:36
Chilton completes a practice start at the end of the pit lane and returns to the track
08:38
The track temperature has now hit 40°C, with air creeping up to 27°C
08:39
With the softest compounds in use, tyre degradation is likely to be a key theme
08:40

08:44
Replays show Kobayashi misjudging his entry to the first corner
08:44
Hamilton is having a discussion with boss Toto Wolff in the Mercedes garage

08:56
Rosberg now takes over, lapping in 1:19.276
08:57
Hamilton slots into second, three tenths behind his team-mate
08:58
Hamilton improves, but stays in P2

09:07
Massa puts himself back ahead with a small improvement
09:07

09:13
Just Ricciardo, Button and Kvyat on track at the moment
09:19
The track action has intensified with the minutes ticking down
09:21
Few improvements are on the way, however, with tyres reaching the end of their life
09:24
Van der Garde runs wide at the first corner, but keeps his car facing in the right direction
09:24
The Dutchman escaped unharmed from a massive shunt at the Silverstone test
09:25
But in general, there have been plenty of mistakes on track this morning
09:26
This is likely due to the removal of FRIC, with cars reacting differently
09:28
09:30
The chequered flag comes out at Hockenheim
09:30
