Kyle Busch competes in the NASCAR Cup Series, where all drivers use purpose‑built stock cars that conform to a single set of specifications. The chassis, engine displacement, and body templates are standardized across manufacturers, meaning the term “Kyle Busch car” refers to a Chevrolet Camaro‑based race car that meets the series’ 2022‑2024 rulebook.
Public race footage, official entry lists, and the team’s press releases consistently list the make as Chevrolet and the model as the Camaro ZL1 body style. Beyond the make, specifics such as horsepower, aerodynamic package, or liveries are determined by the team (Joe Gibbs Racing) and can change from race to race.
