Lewis Hamilton moved ahead of Mercedes team-mate Nico Rosberg during second practice for the Malaysian Grand Prix, grabbing the top spot by just over two-tenths as the pair bolted on a set of the soft tyes to dominate the field.
Ferrari's Sebastian Vettel was third quickest ahead of team-mate Kimi Raikkonen, although the duo found themselves more than half a second adrift of Hamilton's 1m34.944s, in Raikkonen's case that was closer to a second.
Ferrari look to have the advantage over Red Bull however with Max Verstappen fifth ahead of Force India's Sergio Perez and McLaren's Fernando Alonso, whilst the second Red Bull of Daniel Ricciardo could only manage eighth.
Jenson Button and Nico Hulkenberg completed the top ten.
The session saw very little drama unlike opening practice in which Kevin Magnussen's Renault burst into flames. His team managed to get things repaired for the second session and whilst Magnussen finished P19 – seven-tenths down on team-mate Jolyon Palmer – the Dane will be thankful for 19 laps he managed to complete.
