Sebastian Vettel shows no signs of letting up this weekend at Korea International Circuit.
Fresh off back-to-back wins and nipping at the heels of World Championship leader Fernando Alonso, Vettel led Saturday's final practice ahead of Korean GP qualifying.
Vettel, who also paced the second of Friday's two practices, topped the P3 time sheet with a lap of 1:37:642 that easily beat out the McLarens of Lewis Hamilton (1:38:169) and Jenson Button (1:38:511).
The Lotus entries of Romain Grosjean and Kimi Raikkonen filled out the top five, followed by Alonso, Mark Webber, Felipe Massa, Pastor Maldonado and Nico Hulkenberg.
Sunday's Korean Grand Prix marks the 16th of 20 events on the 2012 Formula One calendar, which concludes in late November with the Brazilian GP.
Coming into the weekend, Alonso leads the drivers' standings by four points over Vettel, a winner last weekend in Japan and two weeks earlier in Singapore.
Raikkonen (-37), Hamilton (-42) and Webber (-60) complete the top five.
Alonso, Vettel and Hamilton each own a season-high three victories, while Webber and Button, both with two victories, are the season's other repeat winners.
