IndyCar is the premier open wheel racing series in the United States. IndyCar features street races, road races, and oval track races around the country, including the world famous Indianapolis 500. "Indy cars" are technologically quite sophisticated, as they are built only for racing. One particular Indy car this season will be sporting a clean, new nuclear-themed look, courtesy of the Entergy, the second largest owner and operator of nuclear power plants in the United States.
