On Wednesday, fans watched 30 NASCAR Sprint Cup Series drivers take to the track in the sixth-generation car test at Charlotte Motor Speedway from the enclosed Clubhouse seating of The Speedway Club.

NASCAR ran five different mock races, as well as several tuning sessions with cars completing single-car runs. The test session was intended to finalize rules packages for the 2014 season.

"We did an initial test here in October," said Gene Stefanyshyn, NASCAR Vice President, Innovation and Racing Development. "We got some information. We've been very fortunate that we've actually had a huge participation. We have 30 cars out there. We're trying to exercise all this in a real world environment."

"It is different when you have 30 cars, or 25 cars, versus the six (from October)," said Robin Pemberton, NASCAR VP of Competition and Racing Development. "It was important that we come back with a field of cars like we did. It gave us a little bit of a different view of some of the answers and has put us in some different directions that we will continue to work on."

The stars of NASCAR return to Charlotte Motor Speedway during the 10 greatest days in racing, highlighted by the NASCAR Sprint All-Star Race and the Coca-Cola 600. Fans can catch all the action, including reserved seats with the best views of pit road and the world's largest HDTV with weekend packages starting at just $99.

After testing concluded, fans were invited to enjoy Speedway Christmas, the region's largest holiday light show, which runs through Dec. 30. The 3.1-mile course allows families to experience more than 3 million lights and 800 holiday displays. The show is open from 6 to 10 p.m. and admission is only $15 per car on Monday through Wednesday when the infield Christmas Village is closed, and $20 per car Thursday through Sunday when the Christmas Village is open.
