Pontiac Catalina 421 “Swiss Cheese” (1962) 1 million
In 1961, Pontiac engineers manufactured numerous aluminum parts like bumpers, fenders, hoods, and so on, saving 159 pounds from the heavy car. Moreover, the vehicle was nicknamed “Swiss Cheese” since they also drilled holes in the car’s frame to save a few more grams. These Catalinas were lightning quick with a high-compression 421 V8 engine and 410 HP. Needless to say, “Swiss Cheese” Catalinas proved to be the fastest on the strips and won numerous races, earning Pontiac some much-needed publicity.
