World Champion Sebastian Vettel has praised his Red Bull team's ability to continue producing a race-winning car.

The 24-year-old, who retained the world title last week in Japan, claimed victory during this morning's Korea Grand Prix to help Red Bull win their second successive constructors championship.

"It's good to see that the whole team keeps on pushing," said Vettel. "To come here and after a tough Friday and Saturday to come back in the race was fantastic.

"At the end it was fantastic I was able to push when I wanted to. It's fantastic [to win] last week the drivers' championship and this week the constructors' championship."

Vettel is the youngest ever driver to become a double champion.
