Elliott to drive for Red Bull UPDATE: Red Bull Racing is planning to announce that former Nextel Cup champion [1988] Bill Elliott will drive for the team for three races this season as the team prepares a full-time entry into Cup racing with Toyota in 2007, a source close to the situation has confirmed. The car Elliott will drive will not be a Toyota, but the make of car has not been determined. He will attempt to qualify for the races at Charlotte and Atlanta in October and Texas in November. He also is running select races this year for MB2 Motorsports and Michael Waltrip Racing. The Red Bull team will use the races to help get its crew ready for the Daytona 500 in 2007. Drivers and crew chiefs for 2007 have not been announced.(SceneDaily.com), Elliott is also scheduled to run five races for Michael Waltrip Racing in the #00 Burger King Chevy at Chicago, New Hampshire [July], Indy, California Homestead.(6-5-2006)
UPDATE: Originally scheduled to debut in 2007, Team Red Bull today announces a short schedule of three NASCAR NEXTEL Cup races it plans to enter in the fall of 2006 with veteran driver Bill Elliott, a two-time Daytona 500 winner, behind the wheel. “The organization and its competitive spirit are what attracted me to Team Red Bull,” says Elliott, who won the NASCAR Winston Cup driver’s title in 1988. “My job is simple . put the car in the show, drive it toward the front, and provide valuable input so that Team Red Bull is fully prepared by the Daytona 500. It’s really a great role at this stage of my racing career.” Leading the preparation of the non-Toyota equipped car are two recent race staff additions, Competition Director Elton Sawyer, a stock car racing veteran, and Technical Director John Probst, one of the racing industry’s top vehicle dynamics engineers. Sawyer and Probst join Gaunt and another appointee, Guenther Steiner, who came over to Team Red Bull from the Red Bull Racing F1 operation in a technical advisor role, as the team’s racing leadership operating out of the race shop in Mooresville, NC. The 60,000 sq. ft. facility recently underwent a Red Bull make-over since the energy drink company acquired the property from Penske Racing South prior to the team’s January 24 announcement by Toyota. Gaunt says the driver agreement with Elliott spans over three NEXTEL Cup races this fall – Charlotte, NC (Oct. 14), Atlanta, GA (Oct. 29), and Ft. Worth, TX (Nov. 5). Starting with the 2007 NASCAR NEXTEL Cup season, Team Red Bull will field two, full-time Toyota Camry entries. Rumors notwithstanding, more “official” information on the new team—including 2007 drivers and crew chiefs—will be made available later this year.(Red Bull Racing PR/Newsletter)(6-5-2006)
