Jolyon Palmer posted the fastest time as the Singapore weekend got underway with free practice on the Marina Bay street circuit.
The Carlin driver went 0.253 seconds faster than championship leader Fabio Leimer.
Marcus Ericsson was nearly six tenths slower than Palmer in third place, with Caterham’s Alexander Rossi taking fourth.
Mitch Evans was a strong fifth in his first running on the Singapore track, and was the last man within a second of the pace.
James Calado finished up sixth fastest, 0.022s ahead of fellow Briton Sam Bird. Bird, who is Leimer’s nearest title rival and driving in Singapore for the first time, set exactly the same time as eighth-placed Felipe Nasr.
Johnny Cecotto was ninth with Stephane Richelmi in tenth.
