History of the Buick Series 50

The Buick Series 50, introduced in 1940 and produced through 1958 with a brief pause during World War II, marked Buick’s approach to combining high-end comfort with everyday practicality. Initially sharing the extended wheelbase of the flagship Roadmaster but equipped with a less potent straight-eight engine akin to the Special, the Series 50 was engineered for those prioritising passenger comfort and interior space. Throughout its run, it reflected the evolving post-war American taste for generously sized, smooth-riding automobiles. The Series 50 was sometimes marketed as 'Buick Eight' or 'Super Eight', referencing its eight-cylinder powerplant. Buick’s commitment to passenger satisfaction was visible in the model’s plush interiors and advanced features for its time, establishing the Series 50 as a preferred choice among upscale family vehicles.

Model History

The Series 50’s lineage can be traced back to earlier Buick mid-range models. Its predecessor was the Buick Special, while its successor was essentially the continued 'Super' line post-1958. Each model year brought subtle refinements, with post-war examples gaining more ornate styling, increased chrome detailing, and interior upgrades to meet the burgeoning demand for American luxury. Changes in engine specifications and mechanical improvements kept the Series 50 relevant in the full-size segment. Its enduring chassis shared numerous elements with the premium Roadmaster, ensuring strong road presence and ride quality.

Highlights and Statistics

The Series 50 is notable for combining the extended Roadmaster wheelbase with the smaller, more efficient straight-eight engine, delivering ample space without excessive power consumption. This made it ideal for long-distance cruising. Period advertising emphasised advanced comfort features and generous interior appointments.

Technical Data

Special Editions and Collectible Models

While the Series 50 did not often feature factory special editions, collectors particularly value models from milestone years or those equipped with rare factory accessories. Post-war versions with unique trim packages or limited paint finishes, as well as early examples with period-correct equipment, stand out in the classic car market.

Weak Spots and Common Issues

No specific known issues are documented in our current database for the Series 50. As with most American classics of this era, attention should be paid to maintaining the straight-eight engine’s seals, as well as the condition of suspension components and interior materials, which can suffer from age-related wear. Parts availability is generally good due to Buick’s sizable production volumes, but original trim and chrome pieces require diligence to source.

Engine and Performance, Transmission and Handling

With its straight-eight engine, the Series 50 provides steady power delivery and is engineered for smooth, relaxed cruising rather than sporting performance. The ride is supple thanks to the suspension design and long wheelbase, excelling in comfort and highway stability. Braking systems are conventional for the period and require periodic inspection for optimal safety. Manual transmissions were standard until the early 1950s, after which automatic options became available, further reinforcing the Super’s ease of operation. Notable Series 50 models include early post-war examples (1946–1948), valued for their classic styling, and early 1950s Super variations equipped with the Dynaflow automatic transmission which enhanced the relaxed driving experience.

Interior, Comfort, Exterior and Design

The exterior of the Series 50 features Buick’s trademark grille designs, flowing body contour, and extensive use of chrome, particularly in post-war models. Spacious interiors are trimmed in quality fabrics, often featuring a bench seat layout designed for maximum passenger comfort. Original colour palettes ranged from formal black and navy to more vibrant post-war hues. Accessories such as radio units, heater systems, and elaborate two-tone paint were available as factory options. Design refinements over the years included the addition of ornamental hood emblems, stylised badges, and more pronounced tailfins in later years, echoing wider trends in American automotive style.

Other Features

Additional noteworthy aspects include the Series 50’s adaptability for custom restoration projects due to its robust chassis and relatively accessible mechanical layout. The model’s popularity in period ensured a wide range of body styles, including convertible and sedan versions, though sedans remain most common on today’s market.

Summary

The Buick Series 50, especially in its Super designation, represents the height of mid-century American comfort and design innovation.
