Lewis Hamilton topped the second practice session for the Korean Grand Prix, just a tenth ahead of his teammate, Jenson Button.
The McLaren duo finished well clear of the remainder of the field, with Red Bull’s Sebastian Vettel almost two seconds down on the McLaren’s in third.
Fernando Alonso and Mark Webber rounded off the top five in another rain soaked session, though conditions were much improved compared to earlier in the morning.
Nico Rosberg, who finished P8, had a coming together with Jaime Alguersuari (P6) after he failed to judge the braking for T1 and sailed into the run-off. At the time, Alguersuari exited the pits, which runs through the T1 run-off area and was hit by the Mercedes.
As in the morning, several drivers explored the outer reaches of the track as they struggled in the intermediate conditions.
