Williams have announced that their 2017 car will be called the FW40, despite this year's challenger carrying the FW38 moniker.
The name will be to celebrate the team's 40th anniversary, having first entered a Formula One Grand Prix at the 1977 Spanish Grand Prix.
"40 years ago Frank [Williams] and Patrick [Head] created what would become one of the most iconic teams in the history of Formula One – Williams," deputy team principal Claire Williams said.
"We are immensely proud of what we have achieved during our long and illustrious history. We have experienced the most euphoric highs - reaching the pinnacle of the sport nine times as a Constructor and created seven Champion drivers; Alan Jones, Keke Rosberg, Nelson Piquet, Nigel Mansell, Alain Prost, Damon Hill and Jacques Villeneuve. We have also experienced the lows; the heartache that the sport can cause and victories that have agonisingly slipped away."
"So much has changed in Formula One in the last 40 years but one thing remains the same, our passion for motorsport. We want to celebrate our passion, our achievements and our heritage with everyone who has made this journey possible – our fans, partners, media colleagues and the many friends we have made over the last four decades. Racing, it’s in our blood, it’s our DNA and has been since 1977. We are proud of that and that will never change."
