Gen 6 cars
In early February 2013, the Generation 6 Cars were announced as a downloadable content for the PlayStation 3 and Xbox 360. The cars were expected to be released for play sometime around the time of the 2013 Daytona 500. However, due to an issue while trying to release an update, they were not fully revealed until March 31 and released April 2. On October 19, the company officially announced that there will be no more Generation 6 paint schemes due to technical issues.
In the future though, it is expected there will be new downloadable content for each new Sprint Cup Series season, at least through the 2014 season, with new teams and cars with updated paint schemes and might go along with NASCAR '14. This will be unlike the EA Sports series of NASCAR video games, whereas there was a new game released for almost each new Sprint Cup season.
