Nico Hulkenberg starred in Korea as he finished the race in a career equalling best fourth place.
Hulkenberg started the race from seventh place in the Sauber but got ahead of Fernando Alonso at the start.
He subsequently moved up to fifth when Felipe Massa spun at turn three and later passed Lewis Hamilton for fourth place.
“Today I drove one of the best races in my career so far,” said the German, whose future remains uncertain.
“I have had cars in the mirrors before, but today there were a lot and it was a bit annoying.”
“Lewis really put the pressure on at the end, especially in the last sector. I knew I needed to get out of turn one well. The car’s traction was very good today, so that kept me alive against Fernando and then Lewis later on.”
“We were also very fast on the straight. I had a good start, although on the outside into turn one, which was a loss at first, but then I had a real good slip stream and was able to get past on the outside. A big thank you to the entire team for providing such an excellent car today.”
