How One Fatal MISTAKE Destroyed America's Engine King

How Detroit Diesel abandoned the Screaming Jimmy — the rise and fall of America's greatest engine company and one of the most overlooked stories in industrial history. A business documentary on corporate failure, industrial decline, and what happened to the two-stroke engine that built the American interstate. This is the loudest engine ever made. And it isn't only loud — it is among the most prolific heavy-duty engines ever manufactured. At its peak, this engine put American infantry onto the beaches at Normandy, drove the Sherman tanks across France, and ran in more than one in three trucks on the American interstate for nearly fifty years. Two-stroke architecture. A power stroke every single revolution. A supercharger geared directly off the crankshaft. Five million units built. Forty percent of the American heavy-duty market. But by the early 1990s, every on-highway version of this engine had been pulled from production, and the sound was gone from the interstates inside a decade. So why did the company that built five million of them abandon it? This is the story of the Screaming Jimmy and Detroit Diesel — and it starts with one engineer refusing to let his own committee kill it. #DetroitDiesel #ScreamingJimmy #IndustrialDecline #BusinessDocumentary #RiseAndFall #CorporateFailure
