NASCAR announces all-star change

On Wednesday, NASCAR revealed the format for the Sprint All-Star Race, slated for May 22 at Charlotte Motor Speedway. While there are slight changes, many things stay the same in the race to the checkered flag and a $1 million payout.

The first segment of the race will consist of 50 laps, and teams will be required to pit for four tires on lap 25. Teams will also have the option of making a second pit stop when the yellow flies at the conclusion of the first segment.

Segments two and three are both 20-lap segments. Just like with segment one, the caution will come out at the end of segments one and two to allow teams the opportunity to make optional pit stops.

There will be a 10-minute break at the end of the third segment, during which teams can make normal adjustments to their cars. Cars will then line up behind the pace car in the order they finished the third segment to make one lap behind the pace car. After that one lap is when the most noticeable change to the All-Star Race format comes in.

All cars will be required to make a four-tire pit stop after following the pace car for a lap prior to the start of the final 10-lap segment. The order the cars come off pit road will determine the starting order for the final 10 laps.
