It's not clear in what way these changes will filter down to the Nationwide and Camping World Truck Series championships, although NASCAR did reveal that it was to reduce the size of the starting grid for Nationwide races to 40 cars, down three spots from the current maximum. That's to reduce the number of start-and-park cars running in the race. The Truck Series already caps its grid size at 36 entries.
Away from qualifying, NASCAR also said that they were relaxing the rules on testing and will allow organisations to conduct up to four tests at tracks on the Cup calendar, rather than having to organise testing at non-Cup venues.
“We feel like it's time to open that up and allow the teams to manage their testing and get back to facilities that host our events,” said Pemberton. “We made the decision at the end of 2008 to restrict testing, primarily for economic reasons. Now we believe it will be best for the garage and for the tracks to have some testing return in 2013.”
For Nationwide and Truck Series teams, up to two such tests will be allowed. An extra test will be allowed for a team with an official series rookie. NASCAR added that it wil be making more track time available for practice at two additional events for each of the three national-level events in 2013.
