Q1 starts and there's a car out right away.
A few minutes later and we now have three cars on track, with Di Resta just cdoming out to join them.
Looks like Petrov will be the first to set a time.
10 of 24 cars are now out and the fastest four are:-
Petrov
D'Ambrosio
Trulli
Kovalainen
Di Resta sets the fifth time and gors P2.
Some of the cars have now put in a second fast lap and have noticibly improved their positions.
Vettel and Hamilton take to the track now and go P1 and P2 respectively.
Well into the session and only 13 times set.
3 slowest times currently are:-
Maldonado
D'Ambrosio
Glock
16 times have been set now and we have a, not unexpected, split. More experienced drivers faster and less experienced drivers slower. Though there is a bit of an overlap mid-field.
There are 7 drivers still to set times, Liuzzi, Karthikayan, Rosberg, Kobayashi, Perez, Buemi, Alguersuari.
Q1 current drop zone:-
Di Resta
Kovalainen
Trulli
Glock
D'Ambrosio
Liuzzi
Karthikayan
Perez leaps into P4
Liuzzi and Karthikayan in 23rd and 24th places are not showing times as they are slower than the required 107%, but they keep swapping positions with each other, but neither seems to be in any danger of breaking through the 107% barrier.
Q1 current drop zone:-
Heidfeld
Kovalainen
Trulli
Glock
D'Ambrosio
Liuzzi
Karthikayan
Alguersuari and Di Resta under pressure for a place in Q2 in P16 and P17.
