Six cars were made in 1970, 12 cars were made in 1971, and 4 cars were made in 1972. The ""Fat Daddy" Sizzlers" (oversized bodies with huge tires) were introduced in 1973. Mattel put the Sizzlers on a hiatus after that year, and in 1976 they created "Sizzlers II". That next year, the "Night Ridin' Sizzlers" (which had headlights you could turn on or off) were created. Mattel permanently stopped "Sizzlers" production in 1978. They were replaced by another spin off named "Scorchers". The "Scorchers" were "pull back" cars which wound a clock spring when pulled backwards a short distance, which then propelled them forward for several feet.
