in the 1950s, yes, but much quicker cars were available in the 60s. there were chevy caprice four-door sedans that made 425 hp and did 0-60 in around six seconds. that's not far off modern hot hatches (although I suspect the ones with 425 hp were probably less affordable at the time). it was possible to make plenty of power back then; it was mainly the weight that held those vehicles back. the specific model I'm looking at weighed 4100 lbs!
