Though almost 1.5secs from the leaders, Williams and Force India were closely matched with Valtteri Bottas fifth fastest, ahead of Sergio Perez, Nico Hulkenberg and Felipe Massa, the latter embarking on his final Brazilian GP this weekend.
Sebastian Vettel and Kimi Raikkonen completed the top ten after choosing against fitting the faster soft tyres. Even so, Vettel was the only driver to spin during the session, turning around on the exit of turn five in the closing minutes.
Outside the top ten, Carlos Sainz and Daniil Kvyat – who suffered a puncture – followed up in 11th and 12th, ahead of the two McLarens of Jenson Button and Fernando Alonso.
Following the confirmation that Esteban Gutierrez will be leaving the Haas team at the end of the season, the Mexican made way for Charles Leclerc in FP1, the GP3 title contender 21st quickest.
Behind him, Sergey Sirotkin made his second FP1 appearance of the year in place of Kevin Magnussen at Renault, but managed just 10 laps before being struck by technical issues.
