For the fourth consecutive year, NASCAR and Nationwide Insurance have combined to bring the "Dash 4 Cash" bonus program back for Nationwide Series drivers and fans alike.

Introduced in 2009, "Dash 4 Cash" (Twitter hash tag: #Dash4Cash) is a one-of-a-kind element that rewards the highest-finishing eligible driver in four designated races with a $100,000 bonus above and beyond the race purse. Fans also can participate via a sweepstakes that culminates with one lucky fan also winning $100,000.

Its basic format hasn't changed: In four select races during the 2012 season, four drivers who have earned the designation to compete for the $100,000 per-race bonus will "have at it." As a refresher, the "Dash 4 Cash" winner in the designated races does not have to win the race. He or she simply must be the highest-finishing eligible Nationwide Series driver championship contender in those designated races.

There are two key revisions. First, the July 6 race at Daytona will serve as the "qualifier" where the top four drivers to receive Nationwide Series driver championship points in that race will carry the "Dash 4 Cash" designation in the first race of the bonus program, July 14 at New Hampshire. Additionally, for the first time, the four "Dash 4 Cash" races will be successive: The July race at New Hampshire followed by the July 22 race at Chicagoland, the series' inaugural event on July 28 at Indianapolis and culminating at the Aug. 4 race at Iowa.

Driver eligibility is as follows:

* New Hampshire (July 14) -- Top four drivers to receive Nationwide Series championship driver points at Daytona qualify for New Hampshire.

* Chicagoland (July 22) -- New Hampshire "Dash 4 Cash" winner plus top three finishing drivers to receive championship driver points.

* Indianapolis (July 28) -- Chicagoland "Dash 4 Cash" winner plus top three finishing drivers to receive championship driver points.

* Iowa (Aug. 4) -- Indianapolis "Dash 4 Cash" winner plus top three finishing drivers to receive championship driver points.

Another returning perk: Should one driver collect the "Dash 4 Cash" bonus from the three previous designated races and win the Iowa Speedway race outright, Nationwide Insurance will pay an additional $600,000 to that driver in Victory Lane, making $1 million in total bonus money up for grabs at the onset of the program.

"We're looking forward to partnering with Nationwide Insurance for another round of the 'Dash 4 Cash' program," said Steve O'Donnell, NASCAR senior vice president of racing operations. "Since its inception, 'Dash 4 Cash' has brought increased notoriety to the drivers, teams and participating tracks in the Nationwide Series.

"We believe the $100,000 guaranteed winner for the select 'Dash 4 Cash' races will continue to elevate the series. Additionally, the condensed schedule will help our fans follow the exciting storylines and finishes we anticipate with the 2012 program."

"Offering a $1 million bonus opportunity for Nationwide Series teams brings another level of intensity to the race track and more attention to our series," said Jim McCoy, director of strategic partnerships for Nationwide Insurance. "There's a very good chance a driver could get hot and take home the $1 million bonus at the dramatic conclusion of our 'Dash 4 Cash' series at Iowa Speedway, where Ricky Stenhouse Jr. won both races in 2011."

The program isn't just for the drivers. Since the fans drive the sport, they're encouraged to participate as well by visiting www.nascar.com/dash4cash to register for a chance to win $100,000.

As part of the Nationwide Series $100,000 Sweepstakes, four lucky fans and a guest of each will win an all-expense paid trip to the final "Dash 4 Cash" race at Iowa. In addition to a VIP experience, those fans will be randomly paired with the four eligible "Dash 4 Cash" drivers for the final bonus program race at Iowa. The fan whose driver wins that "Dash 4 Cash" award also will receive a check for $100,000.
