DUBAI — Red Bull says it has given the Formula One team's principal Christian Horner a multiyear contract extension. aThe team confirmed the extension Thursday and follows a stellar 2012 season in which the team won its third straight constructors' title and Sebastian Vettel clinched his third consecutive championship. A former junior series driver, Horner got his start running the Arden International Racing team. When Red Bull owner Dietrich Mateschitz decided to set up his own F1 team in 2005, he turned to Horner to run the operation. The 39-year-old Englishman has been running the team ever since. — AP
