Nico Rosberg set the fastest time of a tricky first practice session for the Brazilian Grand Prix as drivers got to grips with a new track surface.

Rosberg set a best time of 1:12.764 to beat team-mate and championship leader Lewis Hamilton by 0.221s at Interlagos. Daniil Jvyat was third quickest - just under a second off Rosberg's time - as Toro Rosso looked competitive throughout FP1.

Fernando Alonso was the only other driver within a second of the fastest time in fourth place, ahead of Felipe Massa in fifth and Max Verstappen in sixth. Verstappen had an eventful session, being quick early on but then having to recover from a big moment at Turn 11 and ruining his tyres with a big lock-up at Turn 1.

Conditions were difficult for all drivers due to a smooth new track surface at Interlagos, and the session was interrupted by a red flag period following a crash for Dani Juncadella.

Juncadella had already had one spin at Turn 6 before he went off at Turn 8 with half an hour remaining to bring out the red flag. Juncadella ran wide on to the kerb approaching the right hander, losing control of the rear and running out of space after correcting the car, causing him to lock up and head straight on in to the barrier.

Kimi Raikkonen appeared to struggle more than most with the low grip, spinning twice late in the session. Having spun at Turn 6, Raikkonen then did the same approaching Turn 12 after the chequered flag.

One driver who was unable to learn about the track was Jenson Button, who completed just one lap in the whole session. Button stopped just as he returned to the pit lane on his installation lap, telling McLaren that everything on the car had shut down. The team later said an electrical issue was to blame, with Button failing to return to the track.

Esteban Gutierrez also hit trouble for Sauber as he completed six laps without setting a time, with an electrical problem with his power unit proving tricky to solve.
