The Dark Story Behind the Chrysler A57 Multibank – The 30-Cylinder Frankenstein Engine

In this video, we uncover the dark story behind the Chrysler A57 Multibank — the 30-cylinder Frankenstein engine built from five passenger car motors bolted together in a star pattern. We explore how Chrysler designed it in just four months, why the US Army and the Soviets both rejected it, and how the British turned it into one of their most reliable tank engines — powering the deadly Sherman Firefly into Normandy. What happened when the engine everyone abandoned became the one that mattered most? #WWII #ShermanTank #ChryslerA57 #TankEngine #EngineeringHistory #MilitaryHistory #ArsenalOfDemocracy #ShermanFirefly #Wartime #EngineeringMarvels
