Pierre Gasly: "It is always a unique challenge driving in Singapore with the conditions.

"It is not an easy one for us as it is very bumpy and that is an area where we tend to struggle more. So, it's been a busy day at the wheel and it's been good to try lots of things to try and further understand what we need to improve our package. The gap to the cars ahead is still not where we would like it to be but we will focus on ourselves and see what we can do to improve. There are a couple of corners here where I know we can do better tomorrow so we will try and work on those. I am feeling good in the car in terms of being comfortable at its limit. We need more than that, though, so we will see what more we can do. We also tried the cooling device today. I must say I don't have any thoughts and feelings on it, so that probably means it was quite seamless and worked as intended."

Franco Colapinto: "We had a productive day on track today, trying and testing lots of different things on the car. It's what Fridays are for, and we have a lot of useful data to go through tonight and make sure we're in the best possible position entering Qualifying tomorrow. Overtaking can be tricky here, so starting as far up the grid as possible will be important to having a good weekend. We managed to put in a lot of laps and complete most of the programme despite the interrupted second session due to some red flags. The laps towards the end of the session I felt the car was improving but I touched the wall at Turn 17 and didn't improve on my lap time. Lots to build on overnight and in Free Practice 3 tomorrow and we'll make sure to keep fine-tuning to try and maximise everything from our package."
