for full FP3 times.
Nico Rosberg completed a clean sweep of all three practice sessions for the Brazilian Grand Prix as Lewis Hamilton edged closer to his team-mate.
Having been quickest in both Friday's sessions to the tune of 0.2s, Rosberg saw that advantage halved in FP3 but he remained on top during a dry session. His time of 1:10.446 is just 0.2s off the Rubens Barrichello's pole time from 2004 – showing how quick the track has become as a result of new asphalt – but with wet weather forecast for qualifying, the dry running could become irrelevant.
Hamilton said he never hooked up a lap throughout Friday practice and he seemed uncomfortable with the balance of his car once again in FP3 as he had a big lock-up at Turn 8 before spinning under braking for Turn 1. Having ruined that set of tyres, Hamilton returned to the pit for a number of set-up changes which limited his running to 20 laps compared to Rosberg's 28, although he did improve on the soft tyres to a 1:10.560.
Felipe Massa was third quickest as Williams looked capable of putting pressure on the two Mercedes cars in qualifying. Massa's best time was 0.429s slower than Rosberg but he was unable to complete either of his next two attempts on softs as he ran wide at Turn 4 and then was held up by Sergio Perez.
Valtteri Bottas was fourth ahead of Daniel Ricciardo and Jenson Button, with the McLaren three quarters of a second slower than Rosberg. Next up were the two Ferraris, with Kimi Raikkonen ahead of Fernando Alonso. Having had an engine failure at the end of FP2, Alonso completed only eight laps in the final practice session before ending his running early.
Kevin Magnussen and Daniil Kvyat rounded out the top ten, while Sebastian Vettel appeared to struggle in 11th place as he ended the session 0.8s off the pace of team-mate Daniel Ricciardo.
The two Force Indias were slowest at the end of practice, with FP3 providing Perez with his first track time of the weekend after Dani Juncadella damaged his car on Friday. Perez was 2.5s off the pace but was running a different program to those around him as he condensed all of his practice work in to 25 laps.
