Sebastian Vettel insists he can still improve despite third F1 crown

The Red bull driver became only the third driver to take a title triple alongside Juan Manuel Fangio and Michael Schumacher this year, but is certain there is still more to come from both him and his Red Bull team.

At just 25, he is still younger than any other triple world champion in the history of F1 and is widely expected to add significantly to his tally of three crowns and 26 victories.

"In terms of results, the last three years and winning the constructors' championship have been perfect but I still feel that there are little bits here and there we can improve on," Vettel told AUTOSPORT.

"That's the philosophy and the spirit that we share in the whole team. You can always do better."

The German is now one of only nine drivers to have won more than two world championships.

But even after sealing his third crown in the Brazilian Grand Prix last month, he is refusing to rest on his laurels and is uninterested in comparing his achievements to those of others while there are still more titles to be won.

"At the moment, I don't really reflect too much on what has happened over the last three years," said Vettel.

"I am extremely happy and extremely proud of what we have achieved.

"If you put it into perspective, it sounds even crazier when you look at the people who have achieved the same or similar in the past.

"It's better not to put it into perspective and to carry on focusing on what we do.

"We are having fun, we are very passionate and that makes the difference.

"We did it our way and that's what made the year very special."
