The Generation 6 car, shortened to Gen-6, was the common name for the car that was used in the NASCAR Cup Series from 2013 to 2021. The car was part of a project to make NASCAR stock cars look more like their street-legal counterparts. The cars have used many different aero and downforce packages to improve their racing characteristics as well as using the safety measures of its predecessor, the Car of Tomorrow. The Generation 6 car has received both praise and criticism from fans and drivers.
The Generation 6 body style was introduced in the 2013 Daytona 500 and was originally scheduled to be retired after 2020 in favor of the new Next Gen car.[2] However, due to the COVID-19 pandemic, the implementation of the Next Gen car was pushed to 2022.[1]

NASCAR is expected to use the Gen 6 car at the 2022 non-championship race at Daytona because of an availability of chassis at the time of launch.
