Description
The Buick Six refers to a series of six-cylinder cars produced by Buick primarily during the 1910s and 1920s. These vehicles marked an important development in Buick’s lineup, offering more power and refinement compared to the brand’s earlier four-cylinder models. As one of General Motors’ leading divisions, Buick positioned the Six as a reliable, higher-performance option for families and professionals seeking a step up in capability and comfort.
Introduced in various forms across different model designations—such as the E-45, E-49, and later models like the Series 20 and Series 40—the Buick Six was known for its smooth-running inline six-cylinder engine. Early versions of this engine displaced around 4.9 litres and produced between 40 and 60 horsepower, depending on the year and tuning. The straight-six design provided a notable improvement in balance and smoothness over four-cylinder engines, which helped reduce vibration and made for a more comfortable ride.
Buick Six models were available in several body styles, including touring cars, roadsters, sedans, and coupes. The touring variants were especially popular, offering spacious, open-air motoring with the flexibility of folding tops and removable side curtains. Over time, enclosed models became more prevalent as consumers demanded better protection from weather and dust.
Stylistically, the Buick Six reflected the transition from the brass-era aesthetic to the more streamlined look of the 1920s. Early cars featured upright grilles, wooden-spoke wheels, and metal-trimmed lamps, while later models began to show smoother body lines, steel disc wheels, and more integrated fenders.
Mechanically, the Buick Six earned a reputation for reliability and robustness. Many of the features that made Buick famous—such as overhead valve engines and solid construction—were standard in these models, making them well-suited to the rugged driving conditions of the time.
Today, the Buick Six holds a place of honor among early American automobiles. Collectors and enthusiasts admire these cars for their pioneering engineering, elegant styling, and the vital role they played in establishing Buick as a trusted name in American motoring.
