23. Cadillac V-16 1930-1940 United States
The Cadillac V-16, or the Caddie Sixteen as it was known, was Cadillac’s flagship car from its premier in 1930 till production halted in 1940. Finished only for custom orders, only just over 4,700 cars were ever made during the eleven years which Cadillac produced them. This was the first V-16 powered car to reach production in the United States. Cadillac began working on the idea of a new “multi-cylinder” car in 1926 under tremendous secrecy. They wanted to design a car that was both more powerful and also had a smoother ride than any other vehicle available. They succeeded and the result is a beautiful, elegant car that packed more punch than anything else of its time. It is too bad that World War II killed demand for the car both in the United States and Europe. Cadillac scrapped the costly production in 1940.
