Carlos Sainz: "We had a really good Friday and we've started my home Grand Prix weekend well. I'm happy with today and I feel very comfortable in the car, but we need to keep working like we are because tomorrow it will all be much tighter than what it looks like today. It feels like we can have a strong weekend here in Barcelona and I'm really looking forward to it!"

Daniil Kvyat: "It was my first Friday with the team, so there were plenty of things to look at and adapt myself to, as well as trying to find the best compromise for tomorrow. We've definitely learned a lot from today and we know in what direction to go in order to make steps forward for the rest of the weekend. I already feel like at home here, the team has really given me a warm welcome and we are working well together."

Phil Charles (Chief Race Engineer): "It has been a pretty good day for us. Carlos worked through all of his program list and some more, so I'd like to thank him for his very good work today. We know Barcelona pretty well from all the laps we do in the winter, but for Carlos to complete his whole program here today means we have collected a lot of useful information to optimise the car around the particular conditions of this weekend - most specifically, the way the track and tyres are interacting in these temperatures, as well as correcting balance for the wind. For Daniil, it has been really nice to re-start our relationship with him and he is settling in nicely already. I would say the whole team is very happy to be working with him and he is already making us laugh in and around the debriefs. In terms of today, there is still a little work to do to get him happy in our car - matching balance to his driving style and getting the best from the tyres - but nothing that should be too tricky and so I am confident he will be ‘on it' this weekend."
