Brazilian Felipe Massa has announced he will retire from Formula One at the end of the season.

The 35-year-old Williams driver, who won 11 races for Ferrari from 2006-08 and finished runner-up to Lewis Hamilton in the 2008 world championship, is out of contract at the end of the year.

"After 15 years in Formula One...this will be my last season," Massa told reporters on Thursday in Monza ahead of Sunday's Italian Grand Prix.

Massa, who survived a near-fatal head injury in Hungarian GP qualifying in 2009, joined former champions Williams in 2014 from Ferrari.
