Lewis Hamilton topped the times on Friday morning for the opening Korean Grand Prix practice session, putting his Mercedes just a fraction of a second ahead of the Red Bull pair.
Just behind Sebastian Vettel and Mark Webber was Hamilton’s team-mate Nico Rosberg, whilst McLaren’s Jenson Button was fifth, Fernando Alonso sixth and the Lotus duo seventh and eighth.
Kimi Raikkonen however crashed out of the session early at the final corner, badly damaging his Lotus.
Marussia stand-in Rodolfo Gonzalez had a similar accident, swiping the nose of Jules Bianchi’s car against the wall.
