found on f1zone.net (this is not my personal opinion, I just quote it.)
"Ferrari are superb under breaking. The car looks like it handles well, doesn't seem to have too many problems with the tyres compared to a lot of other teams.
The Red Bull can get on the throttle quicker than the other teams, in that sense it is in a league of its own. However, after a while it gets a bit twitchier as the tyres wear down.
The Merc is awful, it looks slow and very dificult to handle. It seems to suit Schumacher more than Rosberg.
Mclaren, I don't know what to make of it. It definately looked a lot better in Hamilton's hands than Button's. With Button driving, it was all over the place. It was still nervous and twitchy in Hamilton's hands. It doesn't look slow, but it that quick either.
Lotus Renault, initially I thought the car looked slow, but it looked like it was consistantly heavily fuelled. However, it didn't appear to be too bad on the tyres. It looked consistant and there were a couple of times it didn't look as heavily fuelled and it did look a lot quicker.
Focee India was sometimes looking good and then sometimes looking twitchy. I cant make up my mind with that car.
STR, same as Force India.
Williams, fast car but a little bit nervous at times, I think it is in the top 4.
Team Lotus, looks like it has gained some downforce from last year, however how much of a step forward it has taken is an unknown.
Virgin is again the same as Team Lotus.
HRT, enough said. It looked awful.
I did get up close and personal with some used Pirelli tyres (they weren't Virgins tyres), and I have no idea how many laps had been done on them but they were grained and cracked.
I am no expert, but that was my observations. I could be wrong but Ferrari and Red Bull look to be out in front and the others have quite a bit of a margin to find to catch them up. I am not looking at this from a Ferrari fan perspective, but that is what it looked like from the track. And these observations looked pretty much similar whether the cars were on high fuel loads or not because quite often it was obvious whether they were on a high fuel load or not as the way the cars handled were slightly different and a trend emerged. It is hard to explain."
Finishing races is important, but racing is more important.
