Mercedes driver Nico Rosberg moved to the front of the pack during Friday’s second practice session for the Brazilian Grand Prix at Interlagos.
During flying laps on Option tyres, Rosberg clocked a 1:12.385, 0.458s clear of team-mate Lewis Hamilton, reversing their positions compared to the first session.
Rosberg briefly complained of problems when upshifting from second to third gear but the issue appeared to be quickly resolved, though he later went wide at Juncao and had to take to the grass.
Rosberg’s time was almost a second clear of Mercedes’ nearest rival, Ferrari, as Sebastian Vettel and Kimi Räikkönen placed third and fourth.
Daniel Ricciardo was fifth for Red Bull, while Valtteri Bottas was sixth and later spun at Pinheirinho.
Romain Grosjean was a fine seventh for Lotus having sat out the first session, finishing ahead of Nico Hülkenberg, Daniil Kvyat and Felipe Massa.
Sergio Pérez eclipsed Pastor Maldonado and Felipe Nasr, while Max Verstappen finished a tenth of a second clear of team-mate Carlos Sainz Jr., despite spinning at Laranjinha.
Jenson Button was a lowly 16th, in front of Marcus Ericsson, but team-mate Fernando Alonso was struck by more problems as his Honda power unit failed half an hour into the session.
Flames briefly flickered from the back of the car and he pulled off the track approaching Mergulho, causing the session to be halted while his MP4-30 was recovered.
Will Stevens and Alexander Rossi completed the runners, the latter spinning on approach to Curva do Sol.
Light rain fell during parts of the session but did not have a major impact on track conditions.
