With rain forecast for the race, some drivers have leaned towards wet weather set-ups for their cars, running more wing.

Red Bull’s Christian Horner said during final practice that teams no longer have to make major set-up changes to their cars in wet conditions as current F1 cars have so much downforce.

That’s certainly true for the RB7, but as the data below indicates some drivers in other teams have opted to run with more downforce.

Qualifying times in full

  • Jenson Button bounced back from a string of poor qualifying performances in Brazil – in the last five years he started 14th, 16th, 17th, 14th and 11th at Interlagos.
  • Having been very quick in Q2, Nico Rosberg lost half a second in Q3: “I was maybe a little too slow on my out lap in Q3 so my tyres didn’t work perfectly on my fast lap, and that’s why I wasn’t as quick as in Q2”, he said.
  • Felipe Massa had a troubled session: “In some corners I was locking up the front and in the slower ones I suffered with understeer, in others I lacked traction: all in all, the car was rather difficult to drive. On top of that, it was a rather complicated day. I had to use two sets of softs in Q2 and I paid for that in Q3, as I could only do one run.”
  • Unusually, both Virgins were out-qualified by both HRTs. “The car was bad to drive this morning – suddenly from one run to another it had no stability any more,” said Timo Glock. “So it was difficult to go into qualifying with confidence, even though in the first run the car felt okay. I got a safe lap in then I tried to push on the second set of tyres. I had a very good first three corners but then one of the Toro Rossos came out of the pits right in front of me and just stayed there during his out lap, so I couldn?t go quicker and lost some time.”

Team mate comparisons

Compare the best times of each team’s drivers in the last part of qualifying in which they both set a time.

  • Adrian Sutil made it into Q3 while team mate Paul di Resta missed out. The pair tied 9-9 in qualifiyng over the course of the season, with Sutil beating di Resta 8-2 over the last ten races.
  • Bruno Senna beat Vitaly Petrov into Q3. “I didn?t actually feel I made many mistakes,” said Petrov. “I had quite a quick lap at the end of Q1 but then I lost some grip on my lap in Q2, which left me where it did.”

Speed trap

Here are the drivers? maximum speeds.

  • The straight line speeds give us the best indication of which drivers are running more wing in anticipation of rain. It looks like two pairs have team mates have gone in different directions.
  • Pastor Maldonado suggested he was and this is borne out by the straight-line speeds plus his team mate’s fourth-quickest time through the final sector.
  • The same goes for the Toro Rosso pair, with Sebastien Buemi running more wing than Jaime Alguersuari, but still quicker than all bar four of the others.
