Follow live coverage of the Singapore Grand Prix weekend with F1i.
The Marina Bay Circuit hosts one of the most spectacular races of the season, with the grand prix taking place under floodlights around the city streets. FP3 is the final opportunity for the teams to perfect their set-ups ahead of qualifying at 20:00 local time.
FP1 was topped by Nico Rosberg, but the second session on Friday was a much closer affair as Daniil Kvyat headed Kimi Raikkonen and Daniel Ricciardo. It was the first time this season a Mercedes-powered car has not finished in the top three of a practice session and Lewis Hamilton says the threat to Mercedes is genuine.
With Red Bull and Ferrari getting the better of Mercedes in FP2, the final practice session should provide a true indication of whether it will be the closest qualifying of the year, as it was in 2014.
McLaren looks more competitive too, with Jenson Button hoping to match Fernando Alonso's pace on Saturday, while Manor has to make up for lost time after crashes for both Alexander Rossi and Will Stevens on Friday.
