Jules Bianchi will sample Force India's new VJM05 for the first time at Jerez on Wednesday. The 22-year-old Frenchman, who was announced as the team's reserve driver last month, will get behind the wheel of the car during the morning, before handing over to regular race driver Paul di Resta for the afternoon.
Most of the other teams will run with the same drivers that took part on Tuesday. The exception is Sauber, which will give Sergio Perez his first go in the C31 in place of Kamui Kobayashi.
Michael Schumacher will take on a whole day of driving duties for Mercedes, having relieved Nico Rosberg at the midway point of Tuesday's running with the team's 2011 car.
