That's the end of the morning session. A bit of a damp squib this morning with drizzle coming down in the last hour or so. Hopefully things will brighten up this afternoon.
An update from Ron Dennis. The key points:
-Alonso is perfectly healthy and McLaren hopes he will race in Australia. Waiting on doctors to clear him. If not Magnussen will race.
-Alonso was unconscious for a brief period of time after crash. McLaren puts that down to his head striking either side of the cockpit during impact.
-Was kept in hospital due to heightened awareness over head injuries in sport and because he displayed concussion symptoms. Scan showed he was perfectly healthy.
An actual quote from Dennis: "Fernando is devoid of all injuries". Also refuted the electrocution theory.
The oddest thing was Ron Dennis saying the team is yet to speak to Alonso about the crash and whether he has any recollection of it.
Testing resumes at 14:00 local time - in about 50 minutes - so we will take a little lunch break of our own and be back with you then.
@MikeTheFan: At the moment the regulations are the same as they were at the end of last year. No driver coaching as in "brake here", "less throttle there" but they can still inform drivers of imminent problems with the car. However, it is interesting to see that all teams have fitted a full screen display in the cockpit to offer more info to the driver. Red Bull and Williams were two teams without this feature last year but have it installed this year.
@JanVisser: McLaren says it is another engine problem. Details are a bit thin on the ground at the moment.
@XXX: It is definitely not a priority at the moment. But it's interesting to see that McLaren has taken a different approach to the rear suspension compared to its rivals - as it did last year. We might see a return to the "blockers" mounted to the rear suspension, but I don't see why that would rule out a monkey seat as well. A lot more to come on the McLaren - not least a reliable power unit!
@XXX: Last year's McLaren always struggled for top speed and that was considered to be one of the reasons - when they were running. The other reason was that the Mobil 1 fuel was not as suited to the Mercedes engine as the Petronas used by the works team and that meant they were down on power.
@Glenny: It's fair to say the main problem is the power unit, although each car should be seen as a package (chassis and PU) and McLaren and Honda are very much one team. The main problem is that the team can't uncover any car or set-up issues at the moment because it simply can't do the running.
@GeorgeS.: To be fair to McLaren, it is not uncommon for patients who are knocked unconscious not to recall anything from the accident. A friend of mine had a bike accident in London a couple of years ago and I took him to the hospital when it became clear his memory was stuck on a 30 minute loop asking the same questions. His memory slowly came back (initially he couldn't remember things that happened several months before the accident) but still doesn't remember the accident itself. Of course, each case is different, but memory loss is common in cases with concussion or concussion-like symptoms.
@Prithvi: They still have to work around the PU they are given. In terms of heat-rejection figures and all the information needed for installation nothing will be held back, but they don't have any say in the development route of the PU.
@Salman: I think McLaren's account is entirely plausible and makes sense. I think the unusual thing about the accident was the angle the car hit the wall. It seemed as though most of the energy was dissipated through the chassis (and Alonso's helmet) rather than being absorbed by suspension arms falling off or the front or rear crash structure. The FIA should investigate the matter, not because it is that suspicious but because it can help to inform future safety regulations.
@Kimi_Fan: Most teams stick to what the engine supplier offers, but some go there own way due to partnership deals. Mercedes, Lotus, Williams and Force India all use Petronas - Williams was considering using Petrobras this year as part of its deal with the Brazilian company, but is sticking to Petronas for now. Red Bull and Toro Rosso both use Total with their Renault engine, as Lotus did last year when it had Renault power. Ferrari and Sauber use Shell and Mobil 1 has been working hard with McLaren and Honda to come up with specific fuel and lubricants for the new engine. It is a big part of the story under the new regulations as efficiency, with fuel, lubricants and coolants is vital for getting the most power from the limited fuel/fuel flow rate in races.
@MrTuK: I can't remember an example in recent history. Red Bull exceeded the fuel flow rate last year and BAR famously had a clever (and illegal) secondary fuel tank in 2005, but I can't remember the fuel itself being declared illegal. The fuel suppliers have mobile labs at the races and check the oil after each session. The first signs of an engine failure can often be detected in the oil itself.
@MrTuK: Sorry, should have been oil, not fuel. The fuel is of course used in the combustion chamber. But fragments of metal or impurities in the oil can be traced back to a problem somewhere in the engine.
@GeorgeS.: No, the sun is starting to come through. Hopefully we'll have some more action soon.
@Glenny: They haven't changed a huge amount but all compounds have been tweaked slightly. Pirelli has adapted them to what they expect to be faster cars, but we are expecting more degradation i.e. the evolution of the cars has moved quicker than the evolution of the tyres. The super-soft tyres have been given the most attention over the winter with a new rear construction. It's hard to say who will be best on the tyres in these low temperatures, but Mercedes has looked ominously quick on long runs with little drop off.
