The second Friday practice session for the 2015 Bahrain GP would again see Williams Martini driver Valtteri Bottas leading team-mate Felipe Massa. Valtteri would finish 5th and Felipe 10th. The early part of the session would see both drivers complete longer runs on the medium tyre as well as further aero testing including front wing changes. Late in the session both drivers would compleet soft tyre runs.
