AT&T has been pressuring NASCAR with its lawsuit over how to paint the quarter panels on Jeff Burton's Nextel Cup car as it rebrands Cingular under the AT&T logo. According to papers being filed in the suit, NASCAR officials told Stan Sigman, the president and CEO of Cingular, five weeks ago that in April 2005, George Pyne, NASCAR's CEO at the time, told the Richard Childress-Burton team that it would not allow a change in paint scheme or logos if Cingular was bought and had its name changed. NASCAR further said that its grandfathering of Cingular - after Nextel signed on as the series sponsor - "was tied directly to the Cingular Wireless brand and not the Cingular company." The papers further say that "it is generally not in NASCAR's interest to limit sponsors' participation in the sport." NASCAR suggested that AT&T could sponsor a Busch team or a Trucks team instead, if it wished. That is precisely the route that Verizon has taken. NASCAR's filing refers specifically to Pyne's letter to Childress, dated April 4, 2005. It specifies that "should Cingular be acquired by a third party, the Cingular brand is continually welcome as a team sponsor. However, should the company's name change, we will not allow any paint scheme or branding on the car promoting this new name."
