It is fitting that the 2015 TUDOR United SportsCar Champion will be determined in the final minutes of the 10 hour season-ending Petit Le Mans race here at Road Atlanta. After nine races and 56 hours of competition, a Prototype cage match is expected to play out here at Road Atlanta.

With victories at Mazda Raceway Laguna Seca and Watkins Glen International, the Troy Flis led VisitFlorida.com Racing Corvette DP squad with Michael Valiante and Richard Westbrook (pictured right) hold a six point lead over a potent pair of Action Express entries heading into the 10 hour fight.

The defending champion Action Express Corvette DP team, featuring Joao Barbosa and Christian Fittipaldi, took the win at the Twelve Hours of Sebring and have four additional podium finishes.

Meanwhile, the rapidly rising Whelen Engineering Action Express combination of Eric Curran and Dane Cameron are tied with their AXR teammates Barbosa and Fittipaldi and enjoying every minute of their newfound Prototype success that includes wins at Belle Isle (Detroit) and Road America.

Two past champions that have already posted wins in 2015 TUDOR United SportsCar Championship competition are ready to play the spoiler role here at Petit Le Mans. The 2013 champion Wayne Taylor Racing team with Jordan Taylor and Ricky Taylor are in a ‘nothing to lose’ mode.

They took the victories at Long Beach and Canadian Tire Motorsport Park and could well be leading the championship if not for an early season drive time miscalculation.

To keep the fearsome Chevrolet Corvette DP foursome on their toes, Scott Pruett and Joey Hand are fresh from their first victory of the season for their Chip Ganassi Racing Ford EcoBoost Riley DP prototype at the most recent TUDOR Championship stop at Circuit of The Americas.

Add in the Chip Ganassi Racing victory for Scott Dixon, Jamie McMurray, Tony Kanaan and Kyle Larson in the season opening Rolex 24 At Daytona and the Prototype season has had six different winning cars in nine races.
