For the first time in this race's history, fans will determine the format. The event will continue to be 75 laps in length, but fans will be able to vote on the number of laps in each of the three segments. They'll decide the segments as: 40 laps, 20 laps, 15 laps; 35, 30, 10 or 30, 25, 20.

Fans will also determine the type of pit stop a team makes after the first segment and how many cars will be eliminated following the second round. The choices for team pit stop include: no pit stop, two-tire change or four-tire change. The selections for the number of cars eliminated after the second segment are: none, two, four or six.

In addition, fans will vote on the design of the firesuit to be worn by Miss Sprint Cup in victory lane for the The Sprint Unlimited at Daytona.

Fans can vote on NASCAR's new mobile app, NASCAR Mobile '13, or at NASCAR.com/SprintUnlimited. The voting window closes on Wednesday, Feb. 13.

Twenty-two drivers are eligible for this year's Sprint Unlimited at Daytona, but 19 drivers are posted on NASCAR's preliminary entry list for this event. Those eligible are pole winners during the 2012 Sprint Cup Series season or past champions of the pre-season race at Daytona. A.J. Allmendinger, Bill Elliott and Terry Labonte have eligibility but are not on the entry list.

On Tuesday, officials from Daytona International Speedway announced that the fans will play even a bigger role in determining the format of this race. Fans will now be able to decide the starting lineup. Their three options for the lineup include: number of career wins for each driver (most to least), 2012 Sprint Cup final driver point standings or the order when drivers earned their pole position last season (Daytona 500 first place - season-ending race at Homestead-Miami Speedway last place).

Voting for the starting lineup will take place on the day of the race from 9:30 a.m. - 4 p.m. ET. Fans can cast their vote through a digital app at one of four Daytona Rewards Stations on the speedway's property or through texting.

The top-two drivers in the final 2012 Sprint Cup point standings -- Brad Keselowski and Clint Bowyer -- are not eligible for this race. Neither driver won a pole last year nor have they won a past preseason event at Daytona.

Mark Martin is expected to make his 24th appearance in the Sprint Unlimited at Daytona, which will set a record for most starts in this race. Bill Elliott and Martin currently have 23 starts. Martin had appeared in the most consecutive preseason races with 20 (1989-2008). With his start in this year's event, Jeff Gordon will tie Martin with 20 straight appearances.

There have been eight drivers who have won this race multiple times. They are: Dale Earnhardt, Dale Jarrett, Tony Stewart, Neil Bonnett, Ken Schrader, Jeff Gordon, Dale Earnhardt Jr. and Kevin Harvick. Dale Earnhardt holds the record for most wins with six (1980, '86, '88, '91, '93 and '95).

Just five times in the 34-year history of this race has the winner gone on to win the Daytona 500: Bobby Allison (1982), Bill Elliott (1987), Dale Jarrett (1996 and 2000) and Jeff Gordon (1997). Two drivers have won the preseason race and then gone on to capture the Daytona 500 pole and win the Daytona 500 during SpeedWeeks. Elliott did it in 1987, and Jarrett did so in 2000.

Kyle Busch won this race last year. Busch edged Tony Stewart to the finish line by 0.013 seconds, making it the closest margin in the history of this event.

The 2013 Sprint Cup points season kicks off with the 55th running of the Daytona 500 on Feb. 24. Matt Kenseth won last year's race, which was postponed one day due to rain.
