Sebastian Vettel continued his good run of form in India after setting the fastest time during a truncated final practice session.
Vettel’s time of 1:25.332 was half second faster than team-mate Mark Webber.
The 60 minute session was reduced for 40 minutes due to visibility problems at the Buddh International Circuit.
The lack of visibility meant that the medical helicopter was unable to operate, but race control deemed the situation to have sufficiently improved for the session to begin 20 minutes late.
Fernando Alonso was the closest challenger to the Red Bulls, but was some seven tenths of a second in arrears of Vettel.
Nico Hulkenberg was fourth, ahead of Romain Grosjean, Felipe Massa and Paul di Resta.
Nico Rosberg set the eighth fastest time, with Jenson Button and Lewis Hamilton rounding out the top 10.
Hamilton’s run on option tyres was compromised when Grosjean made an error at Turn 10 and rejoined the circuit in front of the Mercedes.
Kimi Raikkonen was 11th, ahead of Pastor Maldonado, Sergio Perez, Adrian Sutil and Jean-Eric Vergne.
Valtteri Bottas was 16th, with Daniel Ricciardo and Charles Pic behind the Williams,
Esteban Gutierrez set only the 19th quickest time after running wide over a kerb and taking some air in his Sauber.
Giedo van der Garde, Max Chilton and Jules Bianchi rounded out the runners.
