Generation 1 (NASCAR)
The Generation 1 in NASCAR refers to the inaugural generation of post-war cars used between 1948 and 1966. The first generation of stock cars used a strictly-stock body and frame, the doors were strapped with the use of seat belts being required, and a heavy-duty rear axle was mandated to stop the cars from rolling over during a race. These cars were almost identical to their road-going counterparts, albeit with tuning and modifications to the car itself being prohibited. It was also notable for being the only generation of stock cars to use real doors. Examples include the Hudson Hornet, Oldsmobile Rocket 88, Ford Galaxie, Plymouth Belvedere, Pontiac Catalina, and the Chevrolet Impala.
