On a sunny and hot day the Williams F1 team would prepare for the first Friday practice for the 2012 Bahrain Grand Prix. Bruno Senna would again be replaced by Valtteri Bottas for this session, joining Pastor Maldonado. With the start of the session both Pastor and Valtteri would complete their installation laps returning to their pits. The circuit was reverted to its original 5.412 km configuration, rather than that used in 2010. Hulkenberg would set
the first time with a 1m:36.855 on a track that was still quite dusty. Team-mate Di Resta would eventually set a 1m:34.929 after a few laps out in the track. But Hulkenberg would improve with a 1m:34.859.

With thirty minutes of the session complete Pastor would come out followed shortly after by Valtteri. Pastor's first lap would be a 1m:36.764 which would see him sixth. His next lap was 1m:35.613 good enough for fifth. At this time Raikkonen was fastest with a 1m:34.609. Grosjean was second followed by Hulkenberg. With forty minutes of the session complete Vettel would go fastest with a 1m:34.311. Vettel would improve with a 1m:33.877 while second and third were now taken by Schumacher, 1m:34.483, and Rosberg, 1m:34.725. For Williams Valtteri had returned to his pit and with fifty minutes of the session complete was thirteenth. The medium tyre was the favoured one as the teams waited for the track to clean. Rosberg was now second with a 1m:34.249.

Hamilton would take to the track and would set a new fastest time with a 1m:33.572. Pastor was also back out on the track and would set a 1m:35.268 to be twelfth. As the first hour drew to a close the order was Hamilton, Vettel, Rosberg, Button, Schumacher, and Webber in sixth. Valtteri was currently in fourteenth, 1m:35.497, as both drivers continued to complete laps collecting data for the Williams team. With seventy minutes completed both Pastor and Valtteri would return to their pits after lengthy runs. There was a lot of complaints in regard to the drivers struggling for grip.

With the end of the session Hamilton was still fastest from Vettel, Di Resta, Rosberg, Button, Hulkenberg, Schumacher, Webber, Raikkonen, and Grosjean in tenth. Both Force India cars had set their times on the soft tyre. For the Williams team both drivers positions would remain unchanged in what was a session where the dusty track conditions made the conditions difficult and it was understandable that the team may not have been looking to set quicker times.
