Wow! This is insane - forget the car, could you even imagine the fuel bill.

Watch Devels 12.3-liter quad-turbo V-16 make 5,007 horsepower (motorauthority.com)

Another V16.
Photographed by my father in 1950, racing on Sellicks Beach south of Adelaide.
It was supercharged 1.5L and developed 600hp at 12,000rpm.

A rare machine, even then.
