1933 Cadillac Series 452-C V16

Cadillac dwindled continued to offer the V16 model in 1933 as the Series 452-C. Despite the limiting production of 400 units, Cadillac only every sold about 125 cars. These are typically identified by their 3-bar bumpers and lined radiator without a chrome shroud.

General V16 Text

Built to each customer’s individual taste, it became an American icon of prestige and helped the company out-perform Packard and their V12. Cadillac initially prepared the V16 to prodigiously power its flagship model with more cylinders than anything else available. The introductory brochure proudly claimed “Sixteen-cylinder powering, complete individuality in style ”that, in brief, is the story of the Cadillac V16.”

At a time when a custom coach-built body was a symbol of status and wealth, the V16 became the one of the most revered chassis. Cadillac wanted the engine to be as vibration-free as possible, and eight combustion cycles per crankshaft revolution combined with balanced internals meant that a V16 was one of the best available packages.

As early as 1926, Ex-Marmon engineer Owen Nacker designed the V16 from two straight-8 Buick units that shared a common crankcase and crankshaft. Each bank was independently operated and only shared a common, center mounted camshaft which operated the valves with pushrods. The 45 degree angle between the banks was unusually narrow to fit inside the chassis. It was named after its 452 inch cubic displacement and produced 185 bhp which was good for 100 mph. It also used a unique hydraulic valve silencing system that reduced noise and was a novel feature in its day.

Chassis details were straight forward and borrowed from Cadillac’s 353/355 line. This included a huge steel ladder frame, rigid axles and hydraulically powered drums brakes to help with the large weight of the car.

Cadillac general manager Lawrence Fisher and GM’s stylist Harley Earl were largely responsible for the V16s styling. Most of the cars were bodied by Fleetwood in Pennsylvania which was later purchased and moved to Michigan by GM to keep business in-house. The customer could choose between 70 or so available bodies that were elaborately finished and all highly individualized in detail. If that wasn’t enough, Cadillac could also provide a bare chassis to be fitted by the independent styling house of the customer’s choice. These arrangements helped Cadillac excel in the luxury custom market.

The engine bay was as finely detailed as many of the bodies that covered it. Chrome and polished aluminum, were used and the wiring loom was neatly concealed.

The V16 was released right after the stock market crash at the New York Auto Show on January 4th, 1930. It became the first production road car to use the V16 which both Marmon and Peerless were also trying to launch. The first V16 shown was a Madame X Landaulet that was designed by Harley Earl a year earlier for two 314-B V8 chassis. The Landaulet was a limousine with division glass, a leather roof and a folding rear roof portion. Following these two special cars, other 4-door Madame Xs were built by Fleetwood in Pennsylvania and these were among the most expensive bodies available.

Despite difficult times, and a price tag higher than any previous Cadillac, the V16 was ordered in huge numbers throughout 1930. GM paraded six cars for European tour and the cars received acclaim by both the press and public. Production reached 2000 examples by June, but by the end of the year, the economic depression nearly hauled sales.

During an eleven year production, 4076 V16s were constructed in several series. Minor upgrades separated the types which included 452, 452B, 452C, 452D. In 1936 they became the Series 60 and Series 90 a year later. These final production cars used a new wide-angle V16 that offered a much lower profile, but kept the same power rating. This new unit also had a square bore and stroke that lower piston speed and crankshaft stress.

After the initial flourish in 1930, production grinded away for ten years with only fifty units made per year. Later, Cadillac reverted to their V12 unit but only after the V16 had made its lasting mark. In the end, Cadillac lost money on every car sold, but it was worth the cost of propelling the marque as a whole. It was estimated the V16 cost Cadillac 54 million dollars.

To emphasize the V16’s place in Cadillac history, a one-of show car was made for the 2003 Detroit Auto Show. Called the ‘Sixteen Concept’, it used a 13.6 liter engine with around and incredible 1000 bhp and 1000 ft lbs of toque on tap. This show car was part of GM’s initiative to re-establish Cadillac as GM’s top brand. Due to its excessive length, the V16 was not feasible in modern cars.

1933 Cadillac V16 Convertible Phaeton by Fleetwood – sold for $462,000

Fleetwoods were true customs – nearly 50 styles were offered, but only about 10 were built. According to the factory build sheet, the example offered here was ordered by the Chicago factory branch for G. E. Crandell, a Montgomery Ward executive who lived on Lake Shore Boulevard in Chicago. It took Fleetwood 16 weeks to construct, and at $8,000, it was double the price of the eight-cylinder Fleetwood all weather phaeton. For that sum, the new owner received, among other things, a personalized dash plaque giving his name and car number – #143 in this case
