The Russian driver set the eighth fastest time and managed a total of 76 laps. He will combine his F1 commitments with a second season in the Formula Renault 3.5 championship, driving for Fortec Motorsport.
The 18-year-old joined Sauber last August and was announced as the Swiss outfit’s test driver in December. He drove a Formula 1 car for the first time in a demo run at the Sochi Winter Olympic Park, the venue for this October’s inaugural Russian Grand Prix.
“Everything felt great today,” Sirotkin said after a busy day at the Bahrain International Circuit. “It was the first time for me in Bahrain and I liked the track. In comparison to what I am used to driving in World Series by Renault, I have quite a lot more engine power and more acceleration with the Sauber C33.
“On my fast lap in the morning I made a few mistakes, so I probably lost a second. But all in all, it was a good start to the session.”
The 18-year-old added: “It was not easy, but I am glad we completed the 300 kms. We know that there is a lot of potential for improvement and we should all be happy with this.”
Test engineer Paul Russell said it was a “positive day” overall, and Sirotkin “continuously improved his lap times”.
