Hamilton, gettting to grips with his new Mercedes drive, clocked 1 minute 41.614 seconds in cold, rainy conditions at the Catalunya Circuit near Barcelona.

Brazilian Felipe Massa was the second quickest and posted a time of 1:41.848 40 in his Ferrari.

Jean-Eric Vergne had a time of 1:42.155 38 in his Toro Rosso.

The wet conditions meant that times were considerably slower than they were last week at the same venue.

Sahara Force India's Paul di Resta was tad slower than Mark Webber and was the fifth quickest.

Later in the day, Force India confirmed appointing Adrian Sutil as di Resta's partner for the 2013 season.
