The 20 LARGEST Engines Ever Put in Old Cars!

Ever wondered what automotive engineers were thinking when they decided a 6-liter engine just wasn't big enough?

In this video, we explore the most outrageously oversized engines ever fitted into classic cars - mechanical monsters that make modern V8s look like toy motors. From Bentley's massive 8-liter straight-six to Bugatti's aircraft-derived 12.7-liter Royale engine, these pre-war powerplants represent an era when fuel economy didn't exist and bigger was always better. We'll journey through automotive history's most excessive creations, including secret prototypes with 13-liter straight-twelves, supercharged Auburn speedsters, and the legendary Cadillac V16 that started it all. These aren't just engines - they're monuments to an age of unlimited ambition and zero restraint.
