When IZOD IndyCar Series teams unload their cutting-edge machines at New Hampshire Motor Speedway next August they will be rolling out Dallara race cars powered by Honda engines on Firestone tires.

 And according to IZOD IndyCar Series statistics, this generation of Dallara chassis, introduced in 2003, has proven to be the most competitive race car ever constructed.

 The IZOD IndyCar Series has presented 86 races since 1996 with an average margin of victory of less than one second. The current IndyCar race car, the 2003 Dallara, is responsible for 59 of the series’ closest finishes.

 Many of those victories are some of the most memorable in motorsports.

 One noteworthy finish came during the historic 90th running of the Indianapolis 500 on May 28, 2006.  Sam Hornish Jr. won the race by passing leader Marco Andretti a few hundred yards short of the finish line, producing the first final-lap winning pass in the history of the famed May race.  The margin of victory that day was 0.0635 seconds, making it the second closest Indianapolis 500 finish and an instant classic.

 The last points race of the 2008 season was at Chicagoland Speedway and it kept fans on their feet for the entire 300 miles.  Two-time Indianapolis 500 winner Helio Castroneves finished just 0.0033 seconds ahead of another 500 winner, Scott Dixon. The margin of victory was the second closest in IndyCar history.

 With IZOD IndyCar Series officials phasing in a new car for the 2012 season, New England race fans will have only one chance to see the most competitive cars in racing history compete at New Hampshire Motor Speedway.

 As part of its 15-race 2011 season, the IZOD IndyCar Series will visit New Hampshire Motor Speedway on Sunday, Aug. 14.
