KANSAS CITY, Kan. (AP) NASCAR announced a new format for the All-Star Race at Charlotte on Friday that will feature two 50-lap segments followed by a 13-lap shootout in which a portion of the field will be on fresh tires.
The changes are intended to spice up the $1 million dash on May 21.
Drivers will be required to pit for at least two tires in each of the 50-lap segments, with the stop in the second segment coming with at least 15 laps to go. Then, a random draw will decide whether the first nine, 10 or 11 cars will have to do a mandatory four-tire stop for the final segment.

The idea is that cars on fresh tires will have to fight their way to the front over those 13 laps.
