Cadillac V-63 classic cars for sale

History of the Cadillac V-63

Launched in September 1923 to replace the Type 61, the Cadillac V-63 marked a strategic step for Cadillac within the GM portfolio, continuing the V8 engine tradition. Designed by Ernest W. Seaholm, it was built at Detroit’s facilities and sold until 1925. Cadillac, already renowned for its luxury reputation before the GM era, further solidified its standing with the conservative yet mechanically advanced V-63. Over 35,000 units were produced, a testament to both demand and production capability in its brief lifespan.

Model History

The Cadillac V-63 succeeded the Type 61 (1922–23) and set the stage for the later Series 355, which arrived in 1931. As the bridge between these generations, the V-63 was available in at least eleven body configurations at its debut—including sedans, coupes, phaeton, and extended-wheelbase models. The four-seat Phaeton proved most popular due to its price and practicality. The model was withdrawn after 1925, its technical components influencing subsequent Cadillac designs.

Highlights of the Cadillac V-63

The V-63 distinguished itself with a new V8 engine architecture, incorporating a crankshaft layout that greatly reduced engine vibrations and allowed for smoother operation—an uncommon technical feat in 1920s motoring. Four-wheel brakes signified a leap in driving safety. Multiple body styles broadened its appeal. The V-63’s Grand Tourer abilities, paired with elegant Fisher-bodied variants, reinforced Cadillac’s reputation for innovation and refinement.

Technical Data

Special Editions and Collectible Models

While no official limited editions are documented, the 1925 model year introduced a bespoke 'custom' trim—with a backward-sloping windscreen and unique interior detailing—that stands out for collectors and historians. Roadster versions aimed at sporting clientele and extended-wheelbase sedans for formal or chauffeur-driven markets are notable body-style highlights.

Weak Spots and Common Issues

There are currently no specific documented weak spots or common issues for the Cadillac V-63 in our sources. However, as with any 1920s car, attention should be paid to the condition of the mechanical brakes and the original V8 engine during evaluation and restoration.

Engine and Performance, Transmission and Handling

The V-63’s innovative crankshaft design in the V8 engine delivered smoother running and reduced vibration, elevating ride comfort markedly compared to earlier Cadillacs. Power was paired with a solid three-speed manual transmission. The chassis, built on the GM C platform, provided long wheelbases and robust axles suitable for luxury touring. The introduction of four-wheel brakes represented a significant improvement in safety and vehicle control for its era. Noteworthy versions include the popular Phaeton (open four-seater), seven-seat sedan for family and formal use, and the rare Roadster, which appealed to enthusiasts seeking a sporting edge combined with Cadillac’s traditional luxury.

Interior, Comfort, Exterior and Design

Designed under GM’s chief engineer Ernest W. Seaholm, the V-63 featured a lengthened bonnet, sophisticated Fisher bodywork, and multiple configurations to suit different clientele. Interior finishes included high-quality upholstery, unique dashboard instrument clusters, and elegant trim. Exterior design was marked by conservative lines, a prominent radiator shell, and options for custom paint and accessories. In 1925, the 'custom' trim introduced a backward-sloping windscreen for visual distinction. Detachable wheel covers, flexible roof options (for cabriolets/phaetons), and period-correct lighting completed the classic Cadillac luxury aesthetic.

Other Notable Features

The Cadillac V-63's refinement in crankshaft engineering not only benefited Cadillac but was also adopted by Peerless, indicating a broader industry impact. The rapid uptake of technical enhancements, such as the L-head V8 and braking advances, made this model a key reference point for 1920s luxury vehicles.

Summary

The Cadillac V-63, produced from 1923 to 1925, stands out for its innovative V8 crankshaft design, robust selection of luxury body configurations, and its role as a bridge between major Cadillac generations. This model set new standards for engine smoothness, safety, and body style variety in American luxury vehicles, and remains a significant reference point for classic car enthusiasts and collectors focusing on prewar automotive advancements.
