With the AT&T Williams drivers finishing an encouraging ninth and tenth, with Nico Hulkenberg ahead of team-mate Rubens Barrichello, the team would start the second Friday practice session. Nico would be amongst one of the early drivers to take to the track, joined by the likes of Vettel, Massa, Hamilton and Button. Several drivers would make a a quick start to the session. Rubens would follow Nico out onto the track a few minutes later.

The early times would see Buemi go quickest with 1m:48.334, but Nico would move ahead setting the fastest time with a lap of 1m:46.436. Alguersuari would move to the top of the times with a 1m:45.156. As the minutes counted down more and more drivers would set quick times and it would be Hamilton who would top the times lowering the benchmark to a 1m:42.064. Nico would move into second with a lap of 1m:42.172 as the drivers continue their short runs. Next would be Alonso who would go fastest with a time of a 1m:41.928.

As more laps were completed the track was starting to improve seeing quicker times. With ten minutes completed Nico would return to the pits after a short run of five laps. At that time Nico was third behind Alonso and Hamilton. Rubens would move into fourth in his Williams with a lap of 1m:41.757. His next lap would see him improve with a lap of 1m:41.201 to now be in second behind Alonso. Alonso would go fastest with a time of the 1m:40.167. Rubens had joined Nico in the pits after a run of seven laps. He had dropped to third behind Alonso and Rosberg. Massa was now fourth with Kobayashi up to fifth in the Sauber.

But Hamilton would move ahead of Alonso with a time of 1m:40.148. Alonso was in second, Webber third, Rosberg fourth and Rubens in fifth. Rubens would return to the circuit aiming to improve on his current fifth position. Rubens would set a time of 1m:45.966. He was most likely running a heavier fuel load given the drop off in his pace.

With twenty five minutes of the session completed the session was stopped as the marshals removed the HRT of Yamamoto who had spun exiting Turn sixteen and was not able to continue. With the car removed the session was restarted with Alguersuari leading a queue of cars back onto the circuit. Nico was back out looking to improve on his current position of fifteenth. Nico would move up four places to be eleventh, while Rubens was fifth, with a lap of 1m:41.018.

Button would set a time of 1m:40.006 to go fastest by three thousandths. Button was now leading the times as the session came to its halfway point. Schumacher was second, Hamilton third and Alonso in fourth. Button would return to his pit with a lot of smoke from what looked to be his rear brakes. His mechanics would use extinguishers on his car.

Vettel was running very quickly on the softer tyres and would set a new quickest time with a 1m:39.204. On his next lap he would set a time just 0.044 seconds down on his quickest time. He would return to his pit while with fifty minutes of the session completed Rubens and Nico would return to the track. Nico would improve to be twelfth with a lap of 1m:40.891. Webber was continuing to run with the hard tyres and he would set a time of 1m:39.251 to go second behind his team-mate Vettel. Schumacher has chosen to run the soft tyres joined by Alonso and Hamilton. Schumacher would set a 1m:39.921 and that moved him up one position to third. Hamilton would go fastest on his soft tyres with a 1m:38.922.

With nearly an hour completed Webber was is on a quick lap and would set a time of 1m:38.839 to go fastest. Hamilton was now second with Vettel third, as Rosberg moves up to fourth position with a lap of 1m:39.268. Rubens would post an improvement and he would move into seventh position with a lap of 1m:39.812. Massa was now third quickest with a good lap after a few laps on his soft tyres. Hamilton would go back to the top by over half a second with a lap of 1m:38.279. Massa continued to improve moving up the order, going second to Hamilton with a 1m:38.820. Hamilton was now back at the top of the order with Massa second, Webber third, Alonso fourth, Vettel fifth and Petrov in sixth. Alonso would beat his team-mate to second with a lap of 1m:38.537s on his soft tyres.

Kubica was now third quickest also running on the soft tyres. Webber was now on soft tyres for this run while Alonso would move his Ferrari back to the top of the times with a 1m:38.132. Webber would spin exiting Turn 12 but able to rejoin and with seventy minutes of the session completed Webber was able to go fastest with a time of 1m:37.942. Nico would report to the team that his tyres falling to pieces. Webber was now back in the pits. Alonso is second with Hamilton third, Kubica fourth, Massa fifth and Vettel in sixth.

Button was down in fifteen but a run on the softer tyres would see him set a time of 1m:38.726, moving up to fifth. So the the flag would signal the end of the first day of practice in Korea. Webber would set the quickest time with a lap of 1m37.942s. Alonso was second for Ferrari, with Hamilton third and Kubica fourth. Button was fifth ahead of Massa sixth, Vettel seventh, Petrov eighth, Rosberg ninth and Kobayashi rounding out the top ten.

For the AT&T Williams team, despite some early pace, they would end the session with Rubens with thirteenth and Nico in sixteenth. With it later being confirmed that the team was running on fairly heavy fuel loads the times that they set did not give a true indication of their quickest pace.
