Thanks to a run of 234 consecutive green-flag laps to close out Saturday night's Samsung Mobile 500, several track records were broken in the NASCAR Sprint Cup Series race.
The Samsung Mobile 500 also set records for fewest cautions (2) and caution laps (10). The previous marks were five cautions - which occurred on four occasions including November's AAA Texas 500 - and 21 caution laps (2011 AAA Texas 500).
The last three NASCAR Sprint Cup Series races at Texas Motor Speedway have resulted in an unusually high percentage of green-flag laps. Of the 1,002 laps run between the Samsung Mobile 500 and AAA Texas 500 in 2011 and Saturday night's edition of the Samsung Mobile 500, 927 laps have been run under green for a 92.5 percentage.
The 234 consecutive green-flag laps - which began on Lap 101 and continued until the end of the 334-lap race - eclipsed the mark of 122 set in the 2009 AAA Texas 500 (then-Dickies 500) won by Kurt Busch. It led to the fastest Sprint Cup Series race in speedway history at 160.577 mph, smashing the mark of 152.705 mph set in last year's AAA Texas 500 won by Tony Stewart.
