There certainly was a design temperature range for the tires Pirelli made. The colder weather of Barcelona may not be within that range, or at a far end of it.

rubbish life from pirelli last year ? I thought the problem was they were lasting too long , and were to be designed to have shorter life this year ; last year the best teams soon got to grips with tyre usage after whining to start with

race driving is about more than the fastest lap ; tyre life , fuel usage etc always have been and always should be part of the skill set of a driver and the designer so that the cream comes to the top ; the conservative bridgestone policy detracted from those skills

Interesting read for sure. He is only looking at the quickest lap by each team and then comparing that to a supposed fuel load. There are so many other factors such as tire choice, track conditions, etc. This could easily sway these numbers a lot.

Most everyone else I've read has Red Bull and Mclaren in the lead. Then Mercedes and Lotus, next with Ferrari and then the rest.

Ferrari also said they haven't used DRS yet to put in a quick lap. Also, how ideal was their setup and package at that time, engine revs, how faultless was Alonso's fastest lap, engine revs, KERS ? Tooo many unknown variables to make conclusions about these fastest laps in testing. I didn't read the article though, italian isn't my forte.

This guy has Force India Sauber and Willaims pretty much level pegging with McLaren.
I suggest he crunches these numbers again.

He also has Lotus ahead of McLaren if im reading this table correctly.
More could have been done.

not rubbish enough perhaps ?

I feel pirelli have been extrememely brave in risking their reputation in order to produce better racing ...as they were asked to do I admit

but the tyres have to be for the temperatures that the races actually experience , not what has been experienced in testing ; anyone who woke up to -4C as I did will tell you that conditions were not normal for spain , a local told me that it was the coldest for 60 years

The analysis is based on pure care speed. With that, the drivers have to extract that speed from the car. So no, he isnt saying that Sauber and Williams will be fighting with McLaren in Melbourne. He says that the cars have a similar lap time (based on his estimates of fuel carried) if the cars were run with zero fuel. Also you need to take into consideration his last analysis on how the cars use their tires...both of which are also very important to ultimate race pace.

If you guys arent fluent in Italian, there is no way you can just look at some stats that he posted and agree or disagree with what he has said. Even if you translate it, you have lost 25% of what he was trying to get across.

the analysis is based on the fastest laptime the car posted...

so how is it only based on pure car speed and not what the driver extracted?

Iam afraid even this cannot be lost in translation:
> The Red Bull is still ahead;
> The Lotus is the second force;
> The McLaren is the third force;
> Ferrari - Mercedes - Williams is the fourth force;
> Force India-Sauber - Toro Rosso are the fifth force;


I disagree with this^^^^

And I'm certain it hasn't anything to do with the translate button on chrome. :D

From the sped up camera shake and pan I'd say that video isnt being played at x1 speed. Could be wrong tho...
