Lance Stroll: "It is great to be driving in Baku. It is a place that holds special memories for me and it is great fun to drive here. It is so high-speed; you are constantly close to the wall, and it is a challenge for the driver. You can gain a lot of lap time under braking because you arrive at high speeds, and getting the braking point right really helps bring a lap together. I think we made some good progress with the car today; we learned a lot about the set-up and I think we can make further gains with car balance. We will go away tonight, review it all, and try to make improvements for tomorrow."

Sebastian Vettel: "We covered plenty of laps and end the day feeling satisfied that we have done our homework. The track was in good shape from the start, but obviously improved quite a bit during the day. It is a tricky circuit at the best of times, but by the end of the sessions I was finding a nice rhythm. During my laps on the soft tyres, I did not maximise everything and I am sure it is the same for the others because there were a lot of yellow flags, especially this afternoon. So there is more to come. The long runs were a bit cleaner and I have a good feel for the car already. Let's see where we can improve overnight."
