McLaren racing director Eric Boullier has said that while the team are still not where they would like to be, he is "incredibly proud" of the steps they have made in recent seasons.
Despite the turmoil on and off track, Boullier remains pleased and is confident they can make big steps over the upcoming winter break.
"As I always say, we aren't where we want to be, of course, but we're fighting fit and looking ahead to a strong winter of further development.
"I'm incredibly proud of how far we've come in three short years – two on the track.
"[I'm] indebted to the incredible commitment, steadfast loyalty and unwavering support demonstrated by our team members in the UK and Japan, our partners, and our amazing fans."
