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. FP1 will take place in daylight before the sun sets, with the teams testing new parts during the practice sessions.
Manor will run a new driver in the shape of Alexander Rossi, who is taking part in five of the final seven races this season in place of Roberto Merhi. Rossi has driven in F1 practice sessions before but it will be his first race.
Sauber is introducing a major aerodynamic update, while a number of teams are bringing new parts to the street circuit.
You can follow all the live coverage on F1i's live page, which can be bookmarked as it will provide commentary on every session of the 2015 F1 season.
