Sebstain Vettel was once again the dominant driver, taking pole position for the Korean Grand Prix as he bids for a fourth straight GP win on Sunday.
Again his first run was decisive, and one lap was good enough to assure top spot.
Mark Webber was the first man out on track, the Australian running in the knowledge that his hitchhiking in Singapore would see him drop 10 places down the grid.
Webber's time was good enough to beat both Mercedes drivers on their first run, but Vettel pulled out a quarter of a second's advantage.
In Singapore Red Bull decided that the German's first run was good enough to claim pole—but he headed back out a second time at Yeongam.
Nico Rosberg led the top drivers out on their final tour, but failed to improve his time. Webber followed straight into the pits without setting a time, allowing Lewis Hamilton to nip in front of him.
It meant that Vettel could abort his final lap and saunter into the pits after bagging the 42nd pole position of his career.
His closest rival in the title race will again have considerable ground to make up: Fernando Alonso was the best of the rest in sixth place, leading the drivers who only made one run in Q3. It did seem as if he was in a different race from the German.
