The final day of preseason testing at Daytona International Speedway will have a different look, at least with one car. Kurt Busch will drive a "car of tomorrow" in the final Nextel Cup test sessions Wednesday, getting behind the wheel of Penske Racing's Dodge Avenger. "It's just a matter of us wanting to get ahead of the game and set the curve and raise the bar for people thinking they've got their COT scienced out," Busch said. "We've got ours here ready to go for a speedway test. We've got three built. One is a test mule that will probably not ever be approved."
