Champion driver Sebastian Vettel said Thursday that he and his Red Bull team are still putting themselves under pressure to finish the season in style with the Korean Grand Prix in their sights.
The 24-year-old German clinched his second drivers' title in a row at Suzuka last weekend -- setting the team up to retain their constructors' crown this weekend in Korea.
Vettel said their success will not change anything and they will continue to do the best possible job in all the remaining races.
"We love racing and the moment you come to a race thinking it doesn't matter where you finish is moment you stay at home," he said.
"The championship was the ultimate target. Reaching that before the end of the season is not the usual but nevertheless we come here with pressure.
"The approach will remain the same. It was a tough venue for me last year... I've never been on podium here."
Vettel suffered a difficult race in Japan as he struggled with the degradation of softer tyres, but said the team have worked to fix the problem and is hopeful a new, more aggressive tyre strategy will work in Korea.
"It is true that in other races we always had the luxury to go a lap longer or two but had to pit for strategy reasons, whereas in Suzuka we were the ones pulling into pits first," he said.
"We have a good chance to understand more about tyres, as the tyre approach this weekend is very, very aggressive, so not sure how many stops we will see, surely more than two, maybe five, we do not know yet."
