Nico Rosberg was fastest in opening practice for this weekend’s Brazilian Grand Prix at Interlagos.
Rosberg posted a best lap of 1:12.764 to beat his Mercedes team-mate and title rival Lewis Hamilton to the top spot by two-tenths of a second.
Daniil Kvyat was third for Toro Rosso, almost a second down on the dominant Mercedes pairing, but ahead of both Fernando Alonso and local favourite Felipe Massa.
Max Verstappen, standing in for Jean-Eric Vergne at Toro Rosso for opening practice, survived a number of off track excursions to finish sixth fastest, two-tenths clear of Pastor Maldonado.
Kimi Raikkonen finished the session eighth fastest after two spins.
Kevin Magnussen, who is still yet to be confirmed at McLaren for 2015, was ninth, while Daniel Ricciardo rounded out the top ten for Red Bull.
Several drivers were caught out by the newly resurfaced Interlagos circuit, with Daniel Juncadella, replacing Sergio Perez in FP1, crashing out at Turn 8 with half an hour remaining, prompting a red flag.
Jenson Button and Esteban Gutierrez both missed the majority of the session, with the McLaren man losing power on his opening lap, while the Mexican completed just six laps after an electrical problem.
