Felipe Massa struggled to control his emotions in the final minutes before his 14th and last ever Brazilian Grand Prix.
The Brazilian driver, who will retire from Formula One at the end of the season, was seen crying moments before his final drive at Interlagos.
"I agreed to return this season to help Williams when the call came," Massa said on announcing his retirement.
"I have now enjoyed four great years with the team, but my career in Formula 1 will finally come to an end this season."
Massa went on to achieve his best finish in 15 Grands Prix, holding off Fernando Alonso to claim seventh place.
Sebastian Vettel won the race whilst four-time world champion Lewis Hamilton fought back from the back of the grid to fourth.
Massa, 36, will bow out at the Abu Dhabi GP later in November.
"I'm really emotional today because of all of you guys," the Williams driver said in a special interview with fellow Brazilian Rubens Barrichello on the podium in Sao Paulo.
"Thank you for everything that we passed together, for all the support.
"The energy that I felt today here, to make the best race I could. I'm so happy for my race, did the best the car could achieve.
"Thank you very much all you guys. I love you. Thank you so much."
Massa's son goes on Williams team radio
His eight-year-old son, Felipinho, gave a heart-warming message to Massa on the team radio at the end of the race.
"Daddy, I'm so proud of you. I will support you wherever you go. By the way, I loved your start!"

F1 fans on social media loved the touching message on the team radio.
Fernando Alonso stood by his car and applauded Massa as he came into the pit-lane for the final time in Brazil.
“I’m happy for him. Zero mistakes. I tried to put pressure on him. Hopefully he has a great future in another category and a happy life,” Alonso told NBCSN post-race.
