"Force India say it's "looking unlikely" that Sergio Perez will get out in P2. 'There was a lot of damage and a lot of parts to change,' the team says."
A win for Lewis Hamilton or Nico Rosberg in Hungary might deal a psychological blow to their title rival, but the loser might console themselves by looking in the history books.
No driver has won at Hungary and then gone on to win the title since Michael Schumacher triumphed back in 2004.

"If there was hope that someone might threaten Mercedes in the heat of Hungary - as Ferrari did in Malaysia back in March - it does not look very likely now. Lewis Hamilton and Nico Rosberg dominated the first session.
"Hamilton was highly impressive in the first part of the session, lapping at first two seconds clear of anyone else - and still a second clear after Rosberg's second run.
"The German closed to just over 0.1secs by the end of the session. But it looks already as if Rosberg will have his work cut out this weekend."
It was a dramatic first practice session in Hungary this morning as Lewis Hamilton went fastest while Sergio Perez flipped.
The Mexican was fortunately unhurt after his huge crash but, apparently, will not be running, external in second practice. Not really a surprise, looking at the above picture...
Right, time for a bit of lunch (or maybe it should be brunch?) but we will be back with live coverage of second practice at 12:30 BST.
See ya then.
We are just about done with our coverage of first practice. You can read Andrew Benson's report about the session and Sergio Perez's dramatic crash here.
That was one of the strangest practice sessions I have seen in some time, with Sergio Perez's unusual crash and then Kimi Raikonnen's front wing dropping off.
The two red flags means there will be plenty of work to do for the teams in FP2, which gets under way at 13:00 BST.

"A bizarre session with some incidents we were not expecting but no surprises at the top with a Mercedes one-two."
1) Lewis Hamilton 2) Nico Rosberg 3) Kimi Raikkonen 4) Daniel Ricciardo 5) Daniil Kvyat 6) Sebastian Vettel 7) Carlos Sainz 8) Sergio Perez 9) Valtteri Bottas 10) Max Verstappen
11) Fernando Alonso 12) Jenson Button 13) Nico Hulkenberg 14) Felipe Massa 15) Felipe Nasr 16) Marcus Ericsson 17) Pastor Maldonado 18) Will Stevens 19) Fabio Leimer 20) Jolyon Palmer
Lewis Hamilton finishes fastest in first practice for the Hungarian Grand Prix.
Yes they do, Daniel Ricciardo gobbles up the chance for a few more seconds on the circuit.
Green light on with 50 seconds left. Anyone fancy popping out?
That could well be that. The marshals are out to sweep up the debris but with minutes left there is unlikely to be time for anyone to do anything more in this session.
Frustration for Kimi Raikonnen as he runs on to the kerb at Turn 12, causing his entire front wing to inexplicably drop off, Raikkonen drives over it and punctures his tyre.
"I don't know what happened, I lost a piece of front wing," observes Raikkonen.
Bit more than a piece, mate...
As ever, nothing but a hair's breadth between Lewis Hamilton and Nico Rosberg. The current world champion slices one tenth of a second off his benchmark time, clocking 1:25.141 before Rosberg also improves and is just 0.109s off the pace of his Mercedes' team-mate with his latest effort.
Sauber: Both are off for the last laps in.
Pastor Maldonado is out now but is struggling with a lack of grip as he battles to keep the Lotus on track through corners. All a bit "thrupenny bit", as Ben Edwards puts it.
Will Lotus get some laps under their belt in this final segment? There's been plenty of thumb-twiddling for Joylon Palmer and Pastor Maldonado, whose only appearance on the circuit was to complete installation laps.
Debutant Fabio Leimer has got a solid 14 laps in the Manor and has the 18th fastest time at the moment.
James Rowe: It's clear that Sergio hasn't spoken to the team. Oblivious to the suspension failure and what actually caused the roll.
The track is green again and out stream the cars for the final 15 minutes of this practice session.
