6 Unknown Cars You Were Never Supposed To See! Six cars were built in secret. Some were crushed on government orders. Some sank with ocean liners. Some were buried so deep that nobody could find them again. These aren't movie props or fictional vehicles. They're real cars that were engineered, designed, and built by some of the world's greatest automotive minds — and then systematically erased from history. The Chrysler Patriot was supposed to revolutionize motorsports with hybrid technology that wouldn't become mainstream for sixteen years. But when the company filmed its famous test at Donington Park, the car wasn't even running. A truck was towing it while the driver held a rope and pretended to steer. The project cost millions of dollars and two people their lives, but it never ran under its own power a single time. The BMW Garmisch simply disappeared after a car show in 1970. For forty-nine years, the only evidence it ever existed was old black and white photographs. When BMW's design chief finally recreated it decades later, he had to reverse engineer the entire car from pictures alone. Even the designer, Marcello Gandini, had almost given up hope that anyone would ever find the original. Chrysler's Norseman was the most expensive concept car ever built at the time. It took fifty thousand man hours to construct and cost over two million dollars in today's money. But it was crated aboard the wrong ship — the SS Andrea Doria — which sank in 1956, taking the car two hundred fifty feet down to the ocean floor where it remains to this day. Porsche's 989 was a four-door sports sedan that looked exactly like the 911 model that wouldn't exist for seven more years. The company built it in complete secrecy, then lied and claimed they destroyed it. The prototype actually survived and eventually proved the concept right when the Panamera launched years later. The Saab Catherina had a targa roof three years before Porsche made it famous on the 911. The board rejected it anyway, choosing an inferior design instead. The Catherina sits in a museum today as a reminder of what could have been. Finally, Chrysler gave fifty-five turbine-powered cars to regular American families for free in 1963. The cars ran so smoothly you could balance a nickel on the engine. But when the program ended, Chrysler crushed forty-six of them. The last two were discovered at a nuclear power plant decades later. ____ We do not own the footages/images compiled in this video.
