Daniil Kvyat: "I really enjoyed driving this track today and I'm quite happy with the car and how we managed to get through our programme. We improved the car balance between the two sessions and I have to say that I feel confident for tomorrow, where I hope we will continue on this strong trend and improve even further."

Jean-Eric Vergne: "This morning we had some Power Unit related issues, which compromised our programme a bit but nevertheless our performance didn't look too bad. In the afternoon, while trying different things, we probably didn't go in the right direction but we have a clear picture now on what we have to do for tomorrow. On the positive side, we seem competitive on the long runs, which is definitely an encouraging aspect for the rest of the weekend. Overall I'm happy, as we have a good car and we know what steps to take next."

Phil Charles (Chief Race Engineer): "Overall it was quite an interesting day for us. We tested a few things and played with down force levels across the cars. Both drivers have done a good job to work through their programme and we learned quite a bit, experimenting with the cars. On the long runs JEV looked quite strong, while Daniil looked particularly good on the short runs, so it's a matter of combining these two aspects. There is still some homework for us to do tonight, but hopefully we can put it all together for tomorrow and get both drivers in a good place."

Ricardo Penteado (Renault Sport F1 track support leader): "Spa lived up to its reputation of an engine circuit today, giving us plenty of work! While the Power Unit calibration and mapping was quite good, and Daniil set a strong time in FP2, we still have room for improvement on the energy management side to be competitive over one lap. On JEV's car we had to change the PU thanks to a water leak that occurred during the first session, but we don't expect any further issue. Tomorrow will be interesting as some rain is predicted so we'll try to maximize performance in all conditions."
