During the last test in Barcelona - yes.
However they did better considering all four pre-season test.

Whats so interesting, HRT are not there to help rack up miles so its just normal.

They showed less speed and less consistency then the Merc, especially the final test.
hehehe I am a RF1 fan too and I have faith in them... :D :D

AutoMotorUndSport.de reports that there are rumors that Alonso carried on his quick 1.21,614 lap only 15Kg of fuel and ran on supersoft tyres!!!!
But in terms of tyre conservation the Ferrari is one of the best or the best.

In all of the testing times, one car had the most consistent (within .5 secs) 14 lap run and stopped without changing tires, went back out for three laps running 1 sec faster than the previous 14 laps.

That was Barichello in the Williams.... no other car tested with such consistency or with no drop off in laptime...IMHO

yes I noticed that. I found that a bit strange. I think the car was lighter than the 1.29 times it ran showed.
Or maybe Williams found the key!

On the same day, Webber ran a Low 22.. then switched tires and did a long run (12 or 13 laps), within an hour of Barichello's run... Webber did 28.5, couple high 28,s five or six high 29's then dropped to 32's and 33's on the last four laps.

Three pit stops for Schumi as opposed to four for the others... So much for the Mercedes chewing up the tires. But we have to remember these were not done the same day, or even the same week. So track temperature and weather will make quite a big difference.

At that point, I see the Ferrari around 1.5s quicker than the Mercedes, which would put it only about 0.5s ahead after the updates, but again with times set on different days, it means very little.

So if he did not change the tires, where did this one second improvement come from? Same tires, almost same fuel load, etc.. Interesting.....

3 stops vs 4 you will need a lot of extra speed in the car to make up for another stop even if you had no overtaking to do.
the 4 stopper will inevitably lead to a lot of overtaking to be done in the last laps when your overall elapsed time is not a lot quicker .And if it was ,why not conserve the tyres a bit more and save one stop -erasing the added risk of an additional stop?
I think a lot of teams will be very conservative in the first races ...not fighting for position no daring moves as the tyres will answer by losing their edge much quicker.the patient guys will have a clear advantage .-As soon as you got breathing space you need to push ,but not too much...so the ones trapped behind will wait for the guy in front to pit and make up lost ground.

I was thinking along those lines too. Also, would it even be possible to have tyre deg so different as to save on a pitstop? If we work on crude maths (not taking into account changing fuel etc) we soon find that in a situation with 3 vs 4 stops, the guy doing 3 stops (4 stints) must do 5/4 the laps of the one doing 4 stops (5 stints). That's tantamount to a 25% decrease in tyre wear. Did Prost and Senna ever get to a position where one could save an entire pitstop?

Save for Michael Schumacher's funky 5-stop race back in his Ferrari heyday. 4 or 5. I can't remember which.

In the prost days there was no regulatory tyre stop .And for example Neweys Leytonhouse in the hands of Capelli and Gugelmin somehow managed to go the whole distance without stopping in Le Castellet when all others needed 1 or more stops.When the others realised it was already too late.
thanks to mechanical glitches both ran into problems and Prost won.So also back then it was not just driver but also a car characteristic determining the life of the tyres .Ferrari was famous for gentle tyre use in those days.

Exactly. I was thinking that they would have to be on different compounds, and cars that treat tyres differently too. I don't think that driver alone and driver technique can make enough of a difference to allow an extra stop etc. Not to mention the pace difference required to allow additional stops

I think this may have been mentioned previously, but graphing those 3 race simulations shows approx 0.3 sec lost every lap due to the tires wear even with the fuel-weight going down. Also, the Ferrari showed a greater benefit from making an extra stop as far as having fresh tires and low fuel = fast laps.
