Maldonado drove during the morning session before handing over to Bottas for the afternoon.
"It was a good morning for me," said Maldonado, who completed 79 laps on his way to the fifth quickest time.
" The track was still very cold when we did our first run on new tyres, but the time still looked competitive. We then moved into a race simulation and our race pace looks consistent. We completed our full programme without issue which is positive. The FW35 feels very comfortable to drive so I’m feeling happy."
Bottas set the sixth fastest time, completing 68 laps.
"We started the afternoon with some shorter runs but we still haven’t seen the full potential of the FW35," he said.
"I have been able to improve some things in my driving since yesterday, but there are still things I can work on compared to Pastor. We then completed a race simulation. Unfortunately it was cut a little short due to the red flag at the end, but we were still able to try all the tyre compounds and I was able to get a good feeling for how the tyres behave. Overall, the car feels really nice on the longer runs, which is promising."
Both drivers will test the FW35 again tomorrow, with Bottas conducting duties in the morning session.
