Sebastian Vettel was third for Ferrari, despite a moment at Juncao, while Daniel Ricciardo was fourth as he trialled Renault’s upgraded power unit.
Kimi Räikkönen was fifth for Ferrari, though his session came to a premature end when he suffered a lurid moment under braking for Descida do Lago and spun through the gravel.
Daniil Kvyat posted the sixth best time for Red Bull, ahead of Valtteri Bottas and Max Verstappen, who recovered from a half-spin at the Curva do Sol.
Nico Hülkenberg and Pastor Maldonado rounded out the top 10, the latter sliding his Lotus through Turn 8.
Carlos Sainz Jr. edged out Lotus reserve driver Jolyon Palmer, who once again received an outing in place of Romain Grosjean as he prepares for a 2016 drive.
Jenson Button complained of tyre wear early on before recovering to 13th, ahead of home driver Felipe Nasr, Sergio Pérez and Fernando Alonso.
Felipe Massa suffered a few moments as he placed 17th, leaving Marcus Ericsson and Manor Marussia pair Alexander Rossi and Will Stevens to round out the runners.
