Vettel: No problem adapting to Red Bull

The 21-year-old German enjoyed a strong relationship with STR team principal Franz Tost, technical director Giorgio Ascanelli and then-team co-owner Gerhard Berger at the Faenza-based outfit, but is enjoying the challenge of getting used to working with the staff at Red Bull Racing.

"I have to build new relationships with different people, but I'm not worried," Vettel told autosport.com. "There are many more people working here at Red Bull, and there a lot of people with great potential.

"It's still a young team and it will take time to meld together but I'm extremely confident.

"I felt very comfortable at Toro Rosso. We created something that was very unique and very special with Gerhard, Franz and Giorgio and we did the best we could.

"Red Bull is a new team for me. We may have the same parent company, but it's a completely different environment, atmosphere and philosophy. These things you need to get used to. Red Bull Racing has a lot of potential and it is up to us, as team and driver, to produce it."

The 2008 Italian Grand Prix winner is also confident that the upgrades Red Bull Racing engine suppliers Renault have been allowed to make to their V8 engine will help the team.

"The fact that Renault is allowed to do something to its engine will certainly be no disadvantage and will only help us.

"But to be honest the differences between the engines last year were quite limited. I don't think that just one thing will make a difference. F1 is all about details - it's about the whole car."

Vettel is due to return to testing action at Jerez next month after the new Red Bull RB5 is unveiled on February 9.
