15. Monteverdi Hai 450 SS
Ask anyone who knows those classic supercars from the 1960s and early 1970s if they’ve heard of the Monteverdi Hai 450 SS, and you may be surprised. In fact, most people have never even heard of it. The Monteverdi company was a Swiss manufacturer of high-end coupes and limousines. They became popular for their elegant creations featuring Italian styling, German quality, and American engines. All their models featured Chrysler engines that delivered the raw power most European manufacturers of the period lacked. After a line of beautiful Gran Turismo coupes, Peter Monteverdi, the owner of the company, wanted to enter the supercar market. He decided to produce a car with a rear-mounted Chrysler engine, a low-profile body, and high performance.
They introduced a new model they named the Hai 450 SS in 1970. It featured a new chassis and body, as well as the famous Hemi 426 V8 engine in the back. Monteverdi wanted the most powerful engine Mopar had to offer and in 1970, that was the mighty Hemi. The car was called “Hai,” a German word for “shark.” Despite delivering 450 HP and superb performance, the Hai 450 SS emerged just as the automotive industry slid into the recession. So buyers were hard to find. Eventually, they sold one car at a high price and later produced two more. Monteverdi’s concern for customers contributed to their decision to cease production. He thought it was too fast and aggressive, making the Hai 450 SS dangerous. Today, this is one of the lost supercars and one of the rarest Swiss-built cars ever.
