Felipe Massa has announced that he will retire from Formula 1 at the end of the 2017 season.
Massa intended to exit the sport 12 months ago but was tempted out of retirement to continue at Williams for 2017, in the wake of Valtteri Bottas' Mercedes switch, as a replacement for Nico Rosberg.
However, Massa confirmed on Saturday that the upcoming two events will be his last in the sport, bringing down the curtain on a distinguished career, which has yielded 11 wins and the runner-up spot in the 2008 championship.
"As everyone knows, after announcing my retirement from Formula 1 last year, I agreed to return this season to help Williams when the call came," said Massa.
"I have now enjoyed four great years with the team, but my career in Formula 1 will finally come to an end this season.
"Once more, I would like to say a big thank you to everyone who has supported me throughout this time: my wife and my father, my whole family, my manager Nicolas [Todt] and all my friends, colleagues and sponsors.
"I would also like to add a huge thank you to all of the fans who have been incredibly supportive and passionate over the years.
"I take so many great memories with me as I prepare for my final two races in Brazil and Abu Dhabi, and although they will be emotional, I am looking forward to ending on a high note and preparing for a new chapter in my career."
Williams added that its line-up for 2018 will be announced "in due course."
