Sergio Perez: "The first session was very busy with lots of aero work. It's given us lots of information to help us understand which parts are giving the best performance. We were evaluating the new front wing and will decide tonight if we will continue using it for the rest of the weekend. The evening session went smoothly and we did all the usual things to prepare for the race. Our long run pace is still stronger than our qualifying speed and I think we can come away with some points this weekend."

Esteban Ocon: "The team worked really hard today. It's not easy to change the floor quickly during a session, but the guys did a really quick job and it didn't cost us too much time on track. All the aero work we did today will give us valuable information for the future. The second session was pretty normal. We did lots of laps and I'm feeling quite happy with the car. We made improvements each time, but we are still missing a little bit of pace to be right at the front of the midfield."

Otmar Szafnauer: "The hot track conditions this morning are not representative of racing conditions here so we chose to carry out a big testing programme to better understand the updated parts of the VJM11. Both cars ran with different aero configurations and it was an important day of learning. The evening session was focussed on the usual race weekend preparations and we completed the run plan without any significant issues."
