The final practice session for the 2011 Hungarian Grand Prix would be run under sunny conditions with both AT&T Williams F1 drivers looking to improve from their Friday performances. Team driver Rubens Barrichello would have his sons in the Williams garage as he prepared for the start of the hour long session. With the start of the session both Rubens and team-mate Pastor Maldonado would take to the track returning shortly
after their installation laps. Both drivers would be testing the new rear wing in this session.

It would not be until around twenty minutes into the session that both Rubens and Pastor would come out for their first serious runs. With twenty five minutes of the session completed Rubens was in eighth with 1m:24.954 while Pastor was just outside the top 10 as they continued on their first runs. Rubens would pit but would return to the track still on the prime tyre. Midway through the session Pastor would put two wheels in the gravel seeing him returning to his pit.

With just over twenty minutes left in the session Rubens was tenth with a lap time of 1m:24.954 while Pastor was in fourteenth, 1m:25.265. At this time Vettel was fastest from Rosberg and Hamilton.

Both drivers would go out on their qualifying practice runs, both using the super soft tyre. Rubens would set a time good enough for tenth but despite been substantially quicker on the option tyre Rubens and Pastor would finish the session in fourteenth and fifteenth. Rubens time was a 1m:23.663 while Pastor had set a 1m:23.894. With the end of the session it would be Vettel who was fastest, 1m;21.168, from Alonso and Button.

For the Williams team their pace would most likely see them make it into the second period of qualifying but not any further as they look to find further pace from the FW33. But having said that their final pace in the session was not that far off that of one of their major rivals Sauber and ahead of both Torro Rosso cars.
