The final practice session for the 2011 Turkish Grand Prix would see both AT&T Williams F1 drivers take to the track early on in the session. Both Pastor Maldonado and Rubens Barrichello would remain in their cars after having returned to their pits. Both drivers appeared to be keen to make up for the lost time that they had in the final Friday practice.

Both drivers would return to the track and by half way in the session Rubens would had only completed seven laps. Prior to his returning to the pit lane Rubens had only set a time good enough for twenty third, 1m:33.669. Fastest time at this point was that of Vettel with a 1m:27.134. Rosberg was second from Webber and Petrov.

As the final twenty minutes of the session commenced drivers would start to set times running on the softer tyre. Buemi would go fastest with a 1m:27.080 ahead of Vettel, Rosberg, Webber and Petrov with just over fifteen minutes remaining. On the softer tyre Massa would go fastest with a 1m:26.883. Vettel would move up to second with a 1m:26.940 but he was running on the harder tyre. Rubens would set his first competitive time with a lap of 1m:29.448 to be nineteenth.

Alonso was now fastest with a 1m:26.819 with just over ten minutes left in the session. More drivers were now out on the track with the softer tyre and it would be Rosberg who would go fastest with a 1m:26.446, only to be passed by Schumacher with a 1m:26.038. Alonso was now third and Massa fourth. But Button and Hamilton would move into third and fourth. Webber would move up to third with a 1m:26.476. Team-mate Vettel would move ahead of Schumacher with a 1m:26.037 to go fastest.

For the AT&T Williams team Pastor would finish the session in twelfth, which was encouraging given his problems on Friday, while Rubens was down in fifteenth. Again Pastor would outpace Rubens as they prepared for qualifying. It was reported that Pastor had not been running with KERS making his time even that much more positive.
