Although cars began to show modifications compared to the road-going versions, NASCAR still required a minimum number of cars (500 cars in 1969) to be sold to the general public. For 1969 and 1970, Ford and Chrysler developed aerodynamic homologation special models that were later dubbed the Aero Warriors.^[2]

Changes in the United States automotive market that downsized passenger cars led to the Generation 3 cars in 1981, which featured shorter wheelbase and the cars being increasingly purpose-built.
