Sebastian Vettel emphasised his FP1 pace in Singapore by going fastest again in the second free practice session at Marina Bay.
The world champion, who has endured a tough sequence of grand prix weekends in terms of pace recently broken only by his attrition-assisted second place in Belgium, looked rapid throughout Friday.
In the end Vettel recorded a time more than three tenths faster than his nearest rival - Jenson Button's McLaren.
Fernando Alonso was third quickest for Ferrari ahead of Mark Webber, Lewis Hamilton, Force India's impressive Paul di Resta and Nico Hulkenberg.
The first of the updated Mercedes W03s was eighth fastest in the hands of Nico Rosberg, while Felipe Massa and Romain Grosjean completed the top ten.
The second session, which ran entirely under dry conditions, burst into life quickly and it was the two McLarens of Hamilton and Button that set the early pace on the soft tyres. SECOND FREE PRACTICE
