Red Bull buys full stake in Toro Rosso

VIENNA, Austria (AP) -- Red Bull gained full ownership of Toro Rosso on Tuesday after buying Berger Motorsport's stake in the Formula One team.

Red Bull, led by Austrian billionaire Dietrich Mateschitz, acquired the 50 percent stake controlled by Gerhard Berger in a deal still pending approval by regulatory authorities.

Toro Rosso, long seen as a development team, outperformed Red Bull last year.

Torro Rosso's Sebastien Vettel won the Italian Grand Prix to become the youngest F1 champion. At the end of the season, the 21-year-old German driver swapped teams to ride for Red Bull next year.
