1934 Cadillac Model 452D V16

The greatest period of economic hardship birthed some of the finest engineering feats and most alluring designs ever to grace the expansive roadways. The dwindling market created fierce competition amongst automakers to gain the admiration of the limited pool of buyers, and those who failed in this endeavor were soon out of business. Cadillac was unintentionally best suited for the Depression, as they had begun work on a sixteen-cylinder engine several years before the financial collapse. A near simultaneous introduction of an equally impressive twelve-cylinder model, the deep pockets of its parent company (General Motors), and the creation of the Art and Color Section helped Cadillac weather the Depression. Most other luxury automakers had to invest their limited resources in new engineering technology and designs during the height of the Depression to compete with Cadillac, a near-impossible task.

Cadillac introduced the Sixteen (V16) on January 4th, 1930, at the New York Auto Show, with production continuing through 1940 with a total of 4,076 units constructed.

Known initially as the Series 452A V-16, the name was changed to the 452C following a body redesign in 1933. Another restyling in 1934 resulted in the 452D, and as 452E in 1935. Styling features now included the Fisher Turret Top all-steel roof, though the cars were still built by Fleetwood.

The Multi-Cylinder Race
Bugatti produced a 16-cylinder engine mating a pair of inline eight-cylinder engines, however, it was Cadillac that produced the first true 16-cylinder engine to be designed and purpose-built from scratch. Shortly thereafter, Marmon introduced its own sixteen-cylinder model which they proclaimed as 'the world's most advanced motor car.' Comparatively, they were not wrong, as the car had the mechanical advantage, with its advanced chassis, 200 horsepower (compared to Cadillac's 175 hp), and nearly 400 lbs-ft of torque (higher than that of the Cadillac). The aluminum-alloy engine weighed just 930 pounds, giving the Marmon Sixteen the highest power-to-weight ratio of its time. They were, however, late to the party, and just 365 (possibly 370) examples of the Marmon Sixteen were built over a three-year period before the company was out of business.

Duesenberg relied on raw, race-bred power to outdo the mighty Cadillac Sixteen, and although it prevailed in generating higher amounts of horsepower, the Cadillac V-16 set new benchmarks for smooth, silent, and superbly impressive performance. It was refined, sophisticated, and more than adequate for carrying the large, luxurious coachwork fitted to the behemoth chassis.

Cadillac's Sixteen Cylinder Engine
Clandestine development of Cadillac's sixteen-cylinder engine began in 1926, with cover stories and notations on various blueprints claiming the V-16 was simply Cadillac's engineering contribution to a new GM bus or coach design. The engine design incorporated modern overhead-valve cylinder heads, a 45-degree cylinder bank angle, external manifolds, a silicon-aluminum crankcase, five-point engine mounts, and a single distributor with two sets of breaker points, controlled by two separate ignition coils.

Beyond just modern and sophisticated componentry, it was the first automotive engine ever to be 'styled' with completely hidden wiring and the use of polished aluminum, porcelain, and a pair of valve covers with brushed aluminum ridges prominently featuring the Cadillac emblem. Displacing 452 cubic inches (7.4 liters), the V-16 was conservatively rated at 175 horsepower and delivered incredible low-end torque – 320 foot-pounds at 1,200 to 1,500 engine revolutions.

Thanks to its evenly-spaced firing intervals, large but well-balanced forged crankshaft, and five main bearings, the engine was incredibly smooth, complemented by its whisper-quiet operation thanks to its hydraulic valve silencers.

Specification
The size of the Cadillac Sixteen fluctuated during its production lifespan, resting on a 148-inch wheelbase for 1930 and 1931 before changing to a shorter 143- and longer 149-inch platform in 1932 and 1933. From 1934 through 1937, a 154-inch wheelbase size was used. Equally, the length changed from 222.5 inches in 1930 and 1931, to 216- and 222 inches in 1932 and 1933, 240 inches in 1934 and 1935, and 238 inches in 1936 and 1937. The width measured 73.6 inches initially, growing to 77 inches in 1932, and shrinking to 74.4 inches in 1936.

The solid front axle was suspended by semi-elliptic leaf springs and hydraulic dampers, while the 3/4-floating rear axle used semi-elliptic leaf springs. Four-wheel vacuum-assisted mechanical drum brakes provided the stopping power.

Body Styles
The Fleetwood catalog for the V-16 initially included ten body styles but the number of different job and style numbers built by Fleetwood and Fisher on the Sixteen chassis was approximately 70. Additionally, full custom bodies were built by Murphy, Saoutchik, Vanden Plas, Pinin Farina, Waterhouse, and others. The majority of bodies were 'catalog customs' by Fleetwood. A small number wore bodies by Fisher, and approximately twenty percent of all early body styles were open (cabriolet / roadster) coachwork.

Production
Approximately 2,500 sixteen-cylinder Cadillacs were built in 1930, dipping to 750 units in 1931 and 300 the following year. Between 1935 and 1937, around 49 examples were built each year.

The Cadillac V16 Series 90 (1938 to 1940)
Cadillac introduced a new L-head (inblock valve / flathead design), 431 cubic-inch sixteen-cylinder engine with twin carburetors, twin fuel pumps, twin distributors, twin water pumps, a wider 135-degree V-angle, and a nine main bearing crankshaft. It continued to produce the same 185 horsepower as the previous OHV, five-bearing V16, but it was even quieter and smoother in operation.

The wheelbase now measured 141 inches, and the bodies were shared with the Series 75 V12, and they differed from the firewall forward from the V-8 cars. The eight-cylinder cars had a smaller wheelbase and were further distinguished by trim differences.

Series 90 Production
Cadillac produced 315 examples of the Series 90 in 1938 and 138 in 1939. Production of the 1940 models ceased in December 1939.
