Lewis Hamilton was fastest in the second session and said he was happy with his car’s long-run pace.

But he added he is wary about Red Bull’s potential: “Degradation on the new [soft] tyre seems pretty acceptable; I was still doing decent times at the end of my run. I think there?s still a bit more to come, but we?re looking strong for the rest of the weekend.

“I also felt quite comfortable with the set-up changes we made going into this afternoon?s session, and our long runs seem to be pretty competitive too. You never know what the Red Bulls are doing, but I’m comfortable that we?re there or thereabouts.”

Looking at the data below, a dozen laps into their stints both Red Bull drivers were able to lap closer to their original times than Hamilton was.

That, combined Red Bull’s tendency to hide more of their true pace on Friday, indicates the RB7s are once again in a strong position this weekend.

Here’s the data from the first two practice sessions.

Longest stint comparison – second session

  • Pirelli believe the soft tyre will last for up to 25 laps and the medium 35 laps, with the soft tyre around 0.8s/lap faster.

This chart shows all the drivers’ lap times (in seconds) during their longest unbroken stint:

Ultimate lap times – second session

An ultimate lap is a driver’s fastest three sector times combined.

  • Lotus continue to move away from Virgin and HRT and closer to the midfield. A new rear wing design brought them within half a second of Williams over the three sectors, and over a second-and-a-half faster than Virgin.
  • Jarno Trulli said: “We need to do a bit of work on fine tuning the balance, and I think there?s more to come from the new rear wing, but the update is working and hopefully we can show in qualifying the sort of pace we?ve had recently in the races”

Complete practice times – first session

  • Both of today’s sessions were run in dry conditions – but as Paul di Resta notes there could be rain on the way: “It?s probably one of the best Fridays we?ve had in terms of collecting data ?ǣ although it remains to be seen how useful that information will be if the weather changes over the weekend.”

Complete practice times – second session

  • Lap times in the second session were almost one-and-a-half seconds slower than they were in 2011. “Maybe the tyres Pirelli have brought here are harder than the Bridgestones and also the temperatures are higher,” said Felipe Massa.
  • Massa’s team mate Fernando Alonso is concerned about the pace of the Mercedes: “I think that in the dry we are a bit less competitive than usual: I don?t think I can fight with the Red Bulls and McLarens and, on top of that, one of the Mercedes is very quick.”
  • Jan Charouz was satisfied with his first run in an F1 session: “I think I did quite a good job as I was pretty close to Daniel which was the main goal, I don?t think five tenths are too much.”

Speed trap – second session

  • Toro Rosso were quickest through the speed traps as they have been in several recent races. Jaime Alguersauri said: “We experimented with different levels of downforce over the two sessions and I think I felt happier with the car?s behaviour in the morning, although we will have to assess the data before making a decision about this element of the package.”
