The Cadillac V-12, and its sister engine the V-16, were the logical outgrowth of the popularity and technology of the well-built Cadillac V-8, and the necessity of more powerful mechanisms to move increasingly larger and heavier automobiles. Simply enlarging the V-8 bores was ineffective as it caused certain thermal problems, and superchargers were only practical in racing machines. By process of elimination, more cylinders, a larger displacement, and higher compression became the solution. The V-12 and V-16 engines helped propel Cadillac into competition with the most expensive cars in the world. Although the timing of the production of these cars may have been less than ideal (the v-16 was introduced less than two months after the Wall Street crash), the cars are some of the best ever built by Cadillac.
The V-12s, introduced just nine months after the V-16s, were built on a 140-inch chassis that was also shared by the V-8 that was the mainstay of Cadillac's line-up. The smaller engine was known for free revving and smooth, even power. Twenty different models were available in the V-12 as opposed to over 50 in the V-16 model. The Roadster, the sportiest vehicle in the lineup, was one of the most desirable of the V-12 cars available. Cadillac's current 2003 prototype V-16 takes styling cues from the V-12 and V-16s of this era.Source - SDAM
