Bowlby then worked with Don Panoz to present the idea to representatives from the Automobile Club de l'Ouest, organizers of the 24 Hours of Le Mans.

[7] On February 5, 2013, Marshall Pruett of Speed Channel revealed that Don Panoz would enter the DeltaWing in the road course events on the American Le Mans Series for the 2013 season.

[8] A lawsuit was filed on November 22, 2013, by the DeltaWing consortium (Don Panoz, Chip Ganassi) against the former designer of the DeltaWing, Ben Bowlby and former engine-supplier Nissan for “damages and injunctive relief arising out of theft of confidential and proprietary information, misappropriation of trade secrets, breach of contracts, unjust enrichment, fraud, and negligent misrepresentation.

[9] The lawsuit, arising from the similarly designed and technologically derived Nissan ZEOD RC and BladeGlider concept car, was settled out of court for confidential terms in March 2016.

[10] The DeltaWing was designed to reduce aerodynamic drag dramatically, to allow a marginally faster straight and corner speed than a 2009–2011 Dallara IndyCar on both ovals and road/street courses with half as much weight, engine power and fuel consumption.

[14] The redesign was intended to bring the DeltaWing in line with Le Mans Prototype P1 regulations, and to minimize the chance of the driver's head being hit in the event of an accident.

[15] There are also several other changes to the design: including the adoption of a purpose-built monocoque (rather than the Aston Martin derived one used on the previous car), and addition of a roof mounted air intake.

[19] The car was retired after 75 laps following an accident in which the DeltaWing ran into a concrete barrier at the Porsche Curves after a collision with Kazuki Nakajima's Toyota TS030 Hybrid.

The four drivers at the 24 Hours of Daytona were Meyrick, Legge, eventual Indy Lights champion Gabby Chaves and Alexander Rossi.

[36] The DeltaWing led 15 laps of the 10-hour finale at Road Atlanta, the Petit Le Mans, en route to a season-high fourth-place finish.

The team spent significant time at the front of the field during the first 90 minutes, only to retire due to recurring problems with the car's redesigned gearbox.

In 2016, Legge would have two part-time co-drivers in Andy Meyrick and Sean Rayhall sharing a seat and driving together in North American Endurance Cup, with Andreas Wirth joining them at Daytona.

The team elected not to qualify at Daytona because of poor conditions, but quickly moving through the field, leading a total of 29 laps between Legge and Meyrick before the latter crashed into a stationary vehicle in the semi-blind Turn 1.

[37][38] The bad luck followed the team to Sebring, where the steering broke while running in eighth position, leaving the car to retire from the event.

[39] After starting sixth at Long Beach (which had skipped the event every year since 2013 due to fears of suspension trouble on the bumps of the street course), the team encountered braking issues that would plague them until an engine failure forced the car to be retired.
