Cyril Abiteboul, managing director: The results we see on track at the moment don't do justice to the amount of work and progress that is going on behind the scenes at Enstone and Viry. We are steadily building the team and recruiting more people and our rate of development is high. We saw this during the Silverstone test when we trialled some new aero and suspension parts that we hope will bring some added performance to the car.

Our focus, however, remains our mid and long-term goals and we continue to put a lot of effort into this. That's not to say that 2016 isn't important as a significant amount of resources are still going into racing this year. The results are not necessarily impressive, but we are learning lessons all the time that will serve us well in the future.

We look forward to Budapest, but know that the challenge will be big. Slow, twisty circuits don't necessarily suit us well, but - as I said before - every lesson learnt, however harsh, gives us information for the future.

Renault Sport Formula One Team's Team Principal Fred Vasseur knows what he wants heading to Budapest.

What's the outlook looking to Hungary?
Fred Vasseur: We made some good progress at the Silverstone test and we have two drivers who are highly motivated to deliver after an ultimately frustrating previous Grand Prix so there's nothing to say we can't do a good job.

Where is the team's focus?
FV: We have updates still to come for this season but it's true that much of our development focus is on 2017. We had plenty of parts to bring performance to this year's car at the Silverstone test and if it wasn't for the weather we would have been running a lot more evaluations there. This year is all about developing the team, maintaining focus and getting all the details in place to be able to deliver once we have achieved the stronger performance that we're all working towards. We are still fighting for every position on track at every race we attend. The positive thing is that even though the results are not coming at the moment, the team is still positive. Everyone is working hard and wanting to get to where we can deliver results. It is a team of racers both at Enstone and Viry. We will get where we need to be.

What was learnt at the test?
FV: The British weather certainly wasn't beneficial that's for sure! Sergey Sirotkin did a good job in the car for us again even though he faced the majority of the rain at Silverstone. We were able to get more laps with Jolyon and even though we didn't complete all the programmes and assessments we wanted we still got a good knowledge base from the test.

What happened with the car right at the end of the test?
FV: The car caught fire. This looks to be the result of a hydraulic leak and we're naturally investigating what happened. The fortunate thing is that the fire happened on the final in-lap of the day so we were able to complete all we could for that day. There was no issue for Jo and the fire was soon extinguished.

What were the lessons learnt at the British Grand Prix?
FV: We didn't have a good weekend in many regards. The pace was not fantastic and we had a few incidents during the race too. Our reliability was not where we wanted it to be and there was a mistake in a pit stop which proved damaging to our strategy too. We know the areas where we need to improve.

What happened in that Silverstone pit stop?
FV: It was human error. As a team pit stops are conducted and practiced repeatedly but there is no pit crew that never makes mistakes. When you think about it, it's is truly remarkable that it is possible to jack up a car, change four wheels and lower the car to depart in around two seconds. We are working all the time to make our stops quicker and we understand what went wrong in that isolated instance. We have changed the process to ensure the same mistake can't happen again.

What's the strategy for Esteban's development?
FV: Esteban drove for us in FP1 in Silverstone then he was kept busy by AMG Mercedes for two days of testing at Silverstone so we'll be checking what he's allowed to tell us about that experience! The plan is for him to drive again in FP1 in Hungary as part of his season-long programme.

'The work we have done so far has paid off and now based on our latest spec we are really just looking at the smaller details such as improving the PU in certain conditions,' says Remi Taffin.

How did you feel the British Grand Prix went for the team?
Remi Taffin: It obviously wasn't a classic performance but we didn't have any particular worries. The power unit worked fine and we didn't have any major reliability issues. It's now the fourth race where we have used the new units and everything has worked well. We have now got to the point where we are working on the smaller issues to improve the wider picture and give extra performance through driveability or additional power. Having a reliable and generally driveable PU was one of our major targets this year and now that has been achieved we can work on the bigger picture, together with Enstone. We're learning as a team all the time about operating car and every lesson learnt helps for the future.

Did you test anything specific in the Silverstone test?
RT: The race weekend in Silverstone showed that we could still improve driveability in the wet. We experienced every type of condition over the three days, from heavy rain to a drying track, so we were able to see how the power unit performed in every circumstance. We identified that we could make minor improvements to the driveability in the slippery conditions so we have been concentrating on this in Silverstone. In actual fact we had perfect conditions to get this work done so when we go to another wet event - which will probably be the next race by the way we are going this year! - we will be fully prepared.

What challenges does Hungary present for the team?
RT: We know that slower tracks with lots of tight corners aren't where our strengths lie. In general the car didn't perform well over the kerbs and in the slower turns, but with the extensive work we achieved at Silverstone, Budapest should benefit from new parts and a better understanding of the car. On top of that, Budapest also has short straights between the corners so this could turn into our direction. We hence look forward to Budapest to maximise what we have got.

The same power unit is used in the Red Bull, does this give an indication of the performance potential of the engine now?
RT: It's obviously encouraging to see that the power unit is now capable of fighting on track at the front and going for pole positions. It shows the work we have done has paid off but we know we still need to increase the power output and this is where our focus lies as we know how to achieve that.
