Qualifying
Sebastian Vettel managed to get the pole position by 0.45 seconds and a final lipe time of 1:22.275. Right next to him, completing the first line of the grid, was Lewis Hamilton.
Track evolution
As the qualifying session went on, with the track rubbering in, and the drivers testing the limits of the grip of their cars, the times per lap dropped, and 16 out of the 17 drivers that took place in Q2 were able to improve their times.
The Q3 is the time were all the remaining drivers put all their cards on the table, even those with a superior car who might have been managing their times in Q1 and Q2 push their cars to the limit in Q3. It therefore comes as no surprise that 7 out of the 9 drivers that took place in Q3 were able to improve their times.
