"Renault F1's managing director Cyril Abiteboul said what the team learned about the car in the first half of the year prompted it to decide it needed to improve its Enstone windtunnel, which meant putting it out of action for nearly one month."
"The front wings are super-sensitive, the way that they are hitting the bodywork, hitting the floor, leading edge and so on, they are super-sensitive and we have understood a lot in the windtunnel. This meant the windtunnel was shut down for more than just the [summer] shutdown. That impact on development and the fact that we were working on multiple projects meant that we were delayed, but that was investment. If we want to be at the level we want to be ultimately, we had to do these things. So it is an encouraging sign of things to come."
"It was planned, and was the sort of thing that goes back to the previous ownership because very little investment was done and it is something that we were pushing back, pushing back, pushing back, but at some point we had to do it. With 2021 coming very near, we needed to be ready with everything, even if it meant sacrificing some of this year's development."
