Over the last two days, Brad Keselowski, Tony Stewart, Denny Hamlin, Carl Edwards, Kurt Busch, Jamie McMurray, Paul Menard and Brendan Gaughan all took part in a Goodyear tire test with the next-generation cars at Phoenix International Raceway.
NASCAR vice president of competition Robin Pemberton said information gleaned from the drivers has helped hasten the evolution of the 2013 car. "When you have events that are like this -- Monday, Tuesday, Wednesday -- your relationships are won," Pemberton said. "Everyone is working on a test plan and everybody pulls on the same end of the rope. People have a tendency to drop their guard and talk more openly about the car and the testing and the results of the things that they are testing. We have great relationships with all of our teams and all of our drivers for the most part."
The next test for Goodyear and the 2013 cars is scheduled for Nov. 6-7 at Charlotte Motor Speedway
