NASCAR will test the "car of tomorrow" Jan. 12 and Jan. 19 at Daytona International Speedway. Nextel Cup Series Director John Darby said Jan. 10 that all the teams have been invited to the tests, but he is unsure how many will actually participate in the tests on the restrictor-plate track. About 12 tests for the car, which could debut in 2007, are being scheduled for 2006. Among one of the pieces NASCAR is testing is a wing that goes across the deck lid, Darby said. "There was a lot of favorable results from it," Darby said. "One thing a wing does is that it can duplicate the good parts of aerodynamics in regards to downforce and side-force things without creating the weight that a big spoiler would. It sits up off the deck lid a ways. We can use it a lot for testing purposes to learn more about what the car likes and what doesn't like and take it from there. We have got two choices. We can just go ahead and leave the wings on them or we can go back and take that information [for the spoilers]. It's a test piece for right now
