The Cadillac Sixteen was a concept car only the early 2000s could produce. At a time when companies were flourishing and the technology revolution was well underway, the Sixteen brought outrageous opulence and oodles of power.
The Sixteen is left to the history books, however, since its V16 engine was never of production intent. However, it did inspire a real-life production engine. The Detroit News reports two individuals looked back on the Sixteen concept as inspiration for a V16 marine engine.
The V16 engine found in the Sixteen concept was designed by General Motors, but it was actually built by Katech, the performance house responsible for building high-performance engines for motorsport.
