Fans set Sprint Unlimited format

DAYTONA BEACH, Fla. -- The format for Saturday night's Sprint Unlimited has been set at 30 laps, 25 laps and 20 laps.

The format for the non-points event involving 2012 pole winners and previous Unlimited winners was decided by a fan vote. Fifty-five percent voted for this format. Twenty-three percent voted for 40 laps, 20 laps and 15 laps.

Fans still have the opportunity to vote on two other elements for the 8 p.m. race. They have until the green flag drops to vote for the type of pit stop each team must make after the first 30-lap segment. The options are four tires, two tires or no stop at all.

Fans will have until the start of the second segment to vote for the number of cars that will be eliminated after the 25-lap second segment. The choices are none, two, four and six.

Votes can be cast on NASCAR's mobile phone app -- NASCAR Mobile '13 -- or at NASCAR.com/SprintUnlimited.
