Red Bull adamant it can get stronger

Red Bull believes it can be even stronger in Formula 1 next year as it targets yet more world championship success.

The Milton Keynes-based outfit maintained its domination of the sport with Sebastian Vettel clinching his third consecutive drivers' crown in the Brazilian Grand Prix on Sunday.

Allied to Red Bull having taken its third straight constructors' title, it means the team is amid a spell of success that no team has enjoyed since Ferrari's domination with Michael Schumacher from 2000 to 2004.

Red Bull team principal Christian Horner sees no reason why his outfit cannot build on its areas of weakness this year to achieve even more in 2013.

"We've got such a strong group, we can always learn," he explained.

"We've learned a lot of lessons this year and we'll look to apply them, and that's one of the strengths of this team.

"We are never satisfied. We're always looking inwards, whether that's the drivers, engineers, or technicians.

"It is in all the different departments. It is that spirit and desire that has kept us at the top for three years."

With Red Bull having had to battle back hard from a difficult start to the campaign, Horner has been left in no doubt about the scale of his team's accomplishments this year.

"This is by far our biggest achievement as a team ever," he said. "We were restrained last week [when winning the constructors' championship] as we thought the job was only half done.

"It's been a tough week, but everyone's kept their focus, kept their nerve.

"And what we were faced with here in the rain could not have been more stressful.

"It's not just about today though; it's about the season as whole - all 20 races.

"It's ebbed and flowed and we've fought our way back into it. Sebastian, in particular, has never given up.

"He really wanted this championship. He's driven with great determination and it doesn't ever get any easier."
