NASCAR tests changes to Cup car for 2014 at Charlotte

NASCAR took a major step towards defining changes to the intermediate track package for its Gen-6 Cup car after 30 drivers tested at Charlotte on Wednesday

NASCAR tests changes to Cup car for 2014 at Charlotte

The series built upon data gathered in a previous test in October to trial physical changes to the car including ride height, splitters, skirts and spoilers in an effort to promote more side-by-side racing and overtaking during races.

Gene Stefanyshyn, NASCAR vice president of innovation and racing development, said that the information gathered throughout the day was invaluable.

"We accomplished our goal today," he said. "We wanted to take the results from October and get more data and feedback that will ultimately allow us to arrive at a final set-up for our intermediate tracks.

"With more cars and teams here today [than the six that ran in October], we were able to learn a great deal that will benefit the racing next year and beyond."
