The Formula One teams completed the second of 3 pre-season tests at Barcelona, with Friday the last of 4 day running on Circuit de Catalunya. Pirelli enjoyed seeing all compounds in action over the four days, but teams noticed high degradation on all tyres.
Yet they still go to Barcelona for far more useful testing despite temperature differences. Conclusion: temperatures don't matter, track and surface do.hollus wrote:Jerez is expected to have temperatures of up to 15, even 20C at midday in the sun, at that time of the year. Neither Valencia nor Aragon are.
Of course one can then be unlucky and end up testing at 7C. Still better that the snow you get in Aragon if you are unlucky.
The weather forecast for tomorrow midday in Jerez is 13C. In Barcelona 8C, in Aragon 5C and in Valencia 11C.

In short: not very useful. So forgive me for asking the obvious: why test there at all?!
Note – the last test, and next is in fact at the Circuit de Catalunya, which is very like a circuit they race at during the year
They do need multiple kinds of track – the Circuit de Catalunya is the single most high speed downforce biased circuits on the calendar. They need circuits that test low speed things too.The answer that they need two different tracks makes no sense when one of them is not useful. Costs? I don't think so. Weather? How? Better to have three days in Barcelona than four in Jerez. What else?

Agree with you 100% I don't think the pirelli's were not designed to be used in these cold condtions and that is why tyre degradation is higher....also think that Ferrari is not getting enough temp into the tyres at this stage(kinder to its tyres).....I think coming to some other tracks where temps are a little higher...they might be the ones in the sweet spot of the tyres and if the temps are way hotter they may suffer bit more degradation also...what is more important to me is that Nando made mention that the car responded very well to set up changes ....the car behaved as they expected it to and also what Fry has been saying that they are where they expected to be with the tunnel/simulation data....ie there is correlation and the gains made in the tunnel can be translated to the track..what to me is interesting is the teams with the low degradation right now might be the ones suffering higher degradation come most of the race tracks.....I could be totally wrong however and the only thing we really know is that almost all of the cars will have updates bolted on at some time during next test....f1316 wrote:Exactly.

If it was really hot, they would obviously find that they were overheating the tyres, but the cause would therefore be different and you could argue that you'd therefore see different cars with problems.
In fact, with Scarbs' comments in mind, it seems that Ferrari's problem might well be that they're still quite kind on tyres - i.e. the tyres are not being brought to a high enough temperature and are therefore too hard. The conditions in Barcelona are unlikely to be reporduced at most GPs this year, so the teams' concern is more that this data on tyre is completely irrelevant.

I think the main point he was getting at was Raikkonen was faster in Testing than he was in Qualy for the real race. Which Im finding a little odd aswell. They using the same layout for testing ?
By the time the Barca race came about last year, they'd have realised that they can't push the tyres so hard in qualy without hurting themselves in the race.
Hence Kimi not making Q3 by a single place in a tyre shredding Bahrain (possibly by choice), yet going through the field to take second place come race end.
True, tyres behaviour under these cold conditions are totally different but sometimes even with such conditions we can guess which cars are better or worse with the tyres. And I expect Ferrari to struggle a little bit.Rikhart wrote:Actually Pirelli says it´s exactly the other way around, with hotter track temperatures we will see milder degradation.munudeges wrote:In hotter conditions things are going to be exponentially worse.

That's tyre wear, not degradation. Besides, it's the same for everyone. If you're moving the car around then you're going to have problems, hot or cold.f1316 wrote:Actually Pirelli says it´s exactly the other way around, with hotter track temperatures we will see milder degradation.

What was the original point? That Ferrari's car was getting slower due to the way it was using its tyres; call it what you will, but "to degrade" is simply to get worse, so it was used in a generic sense in this instance.munudeges wrote:That's tyre wear, not degradation.

http://www.f1zone.net/news/engine-maps- ... tus/17878/ Maybe Lotus and Red Bull won't look as good with the proper engine mapping 
Very interesting, we will need to take a look at this weeks last test in order to gain an idea whether or not this so called "engine mapping" was taking place at the previous two tests.OppositeLock wrote:Stories are beginning to surface that the Renault powered teams have been using illegal engine maps.
With the fact that, there is nothing much changed on the engine side, I don't see a reason why this regulation was only applicable for last year. It's a regulation set on engine maps and the engine being the same, the regulation will continue to be applied. Being such smart engineering people, I would expect that rather than assuming the regulation was only for last year, they should have got a clarification from charlie whiting on the matter.Joie de vivre wrote:Reffered for only last year? They gotta be kidding! Yes, they set those regulations only for last year, this year you can map it the way you want ...
