Or even earlier, the 1950 Buick Special Fastback. ( my sister had one of these, 8 cyl inline, engine was about 10 feet long and had to weigh over 2000 pounds itself. )
Some interesting features :
Had 'door closer' type shocks.
Was 6v, the radio had a 'vibrator' to generate A/C.
2 speed Dynaflow, shifted to high about 60, then just kept going. I've seen 130 MPH.
Had at least 5000 lbs of torque.
