Official...Allmendinger to drive 2nd Red Bull car in 2007, #84: 2006 Team Red Bull formally announces a multi-year agreement with American open-wheel race car driver AJ Allmendinger to race the #84 Red Bull Toyota Camry for the 2007 Nextel Cup season. AJ completes the 2007 driver line-up for Team Red Bull that already includes 23- year-old Brian Vickers, who’ll pilot the #83 Red Bull Toyota Camry. Rick Viers, the veteran crew chief who guided the 24-year-old Californian through two successful NASCAR Craftsman Truck Series races for Bill Davis Racing earlier this year, also joins Team Red Bull in the same role for 2007. A former Toyota Atlantic champion and Champ Car rookie of the year, AJ currently stands second in the 2006 Champ Car World Series standings with five race wins. To speed up his acclimation to stock car racing, Bill Elliott has graciously agreed to step aside and let AJ take on driver duties in the Team Red Bull entry for the upcoming 2006 Nextel Cup races at Atlanta and Texas.
