No, they just have a high pressure nitrogen bottle. But usually it's possible to refill it during a pit stop, it have been done in the past at least.

Learn something new every day! Might be off topic, but how many cubic feet of nitrogen do those bottles contain and at what pressures do they hold? Or is that a closely guarded secret?

If it wasn't for the "environmentalists", we would be nuclear-sheiks all of us.

But anyway, the limitation for a rational electric car will always be storage and charding of the electric energy, 1 MW for a 10 minute charge of a 600 MJ battery, not in this lifetime.

Railway cars are simply not comparable, obviously.

I would think that the main limitation with regard to charging would be the power that can be supplied by the electric grid. The european 0.4kV low voltage grid can for instance usually handle 63 amps, which will give a maximum charge of 45 kW. More than that would be expensive in terms of intrastructure.

So there we go,if 45 kW is the charging limit, it would take you four hours to fill up the equal energy of less than 18 liters of gasoline (600 MJ). Not xactly useful for the autobahn would you think?

Very true very true but most people only travel a distance that is easily catered for by a full electric vehicles range and if it is for work the vehicle is then parked for longer than four hours anyway, ideal just to plug in rather than mess around in a smelly petrol station wasting loads more time handling toxic fuel.
Those who travel longer distances than 200 miles every day require specialised (hybrid) vehicles and those that do so just to commute should change their life style anyway.
Sorry about the thread tifo, does anybody know the state of play on Ferrari valve systems?

Indeed Auto, our revered moderators are getting irritated we are swaying off topic, I still believe that one of 32 reciprocating seals at 30 Hz could have been faulty and leaked out the whole flask of Nitrogen. Stranger things have happened, remember Damon Hill in Hungary 97 with a leaking 30 pence bonded washer in the hydraulics?

I agree, however I have seen nothing recently on the issue, does anyone know?

Another element of the F10 package that has undergone close scrutiny in recent weeks is the engine. A lot of work was carried out on the test bench, completing several long runs and this work produced some solutions which it is felt will solve the reliability problems experienced in Bahrain and Malaysia. The team therefore requested and received authorisation from the FIA to make some changes within the framework of the current engine regulations and these modifications will be fitted to the engines to be used in Spain.

This is good, really good - and reassuring!

IMO it was OK to allow Ferrari to fix this problem.
So long as the FIA monitired what was done.
I previously was against any work on the engines outside the regulations,
however I think the restrictions could have resulted in this problem happening to any ot the teams and any of the engines.
There are two reasons. One is of course the restrictions in the regulations preventing engine work and two, the need for the teams to run the cars on weaker fuel mixture for longer periods because of fuel limits, which will increase the exhaust temperatures for longer periods. IMO this was the root cause of their valve problem.

What is different from last years lump that is making them blow up? Nobody else is having these issues... not even the new Cosworth... once again clear proof that Ferrari is cheating and was cheating over the entire winter... and the FIA looks the other way.

If they are leaking air they should be forced to mount a bigger air tank, and not be allowed to make internal changes to the engine. It is absurd that they are allowed to tear up the rules every time their spaghetti management makes a decision that puts them at a disadvantage.

I just came home after a day of work at my dad's factory, making some money in my Holidays. I open internet to look at the F1 News, and WHAT DO I SEE:

FIA approves Ferari engine change!

http://www.autosport.com/news/report.php/id/83320

WHY?? Why do they approve this? Made a bad engine, can't your Italian steel hold the pressure of the RPM's made! BAD LUCK!!!! Next year you have another change to make a beter engine

I DON'T understand it why the FIA aprove this.

Can somebody TRY to explain it in a way that doesn't say: To keep it honoust against the other teams. Because in that way the FIA should approve Hispania TOO, to make changes at their WHOLE car!

Alonso said several times recently that it was not an air leak that was the problem. That it was something else and that they found the way to fix it now. But no mention of what it was...

There already is a thread about the issue of the Ferrari engine failures, so stop opening a new one next time with a title that is useless.

Fyi, the issue was deemed a reliability problem which is a legal reason for making a change.

Whilst there is no proof per se, I think the case to answer is pretty compelling.
I wonder what the reaction would have been the reaction to Mercedes seeking to making a change. I think this is Ferrari making amends for a tank size screw up, or engineering a fault to be able to make a change.

Where have you been when Renault were granted the same? Are you desperate or what?

BTW, personally I don't like this whole equalization thing in F1.

Me neither, equalization is the for the weak. If you can't pay to play go home (or to a lower formula).

Good advice WB; please listen to this Doopie2you.
