Description
The Buick Special Eight Series 40 was a cornerstone of Buick’s lineup throughout the 1930s and 1940s, serving as the brand’s most affordable full-size model while still delivering the quality, engineering, and styling that defined Buick. Designed to offer a balance between cost and refinement, the Series 40 was often the entry point for buyers into the Buick family.
The “Eight” designation indicated its use of Buick’s inline eight-cylinder engine—a hallmark of the brand during this era. This engine, often a 248 cubic inch overhead valve straight-eight in later versions, was known for its smooth, quiet operation and strong torque delivery. Paired with a three-speed manual transmission, and later with the optional Dynaflow automatic, it gave the Series 40 respectable performance and excellent drivability for its class.
Stylistically, the Special Eight Series 40 followed the elegant design trends of the time. It featured graceful lines, rounded fenders, a prominent vertical-bar grille, and tasteful chrome accents. Available in a variety of body styles—including sedans, coupes, convertibles, and fastback Sedanets—the Series 40 could appeal to both families and style-conscious drivers alike.
The interior of the Series 40 emphasized comfort and practicality. While not as lavish as the Super or Roadmaster lines, it still offered durable and attractive materials, clear instrumentation, and options like a heater, radio, and clock. The seating was spacious and supportive, with thoughtful touches such as fold-forward front seats in coupe models for easier rear access.
What made the Special Eight Series 40 especially appealing was its ability to offer the prestige and smooth power of an eight-cylinder engine at a more affordable price point. It was Buick’s answer to drivers who wanted refinement and reliability without stepping into luxury territory.
Today, the Series 40 holds a special place among collectors and enthusiasts for its role in making Buick’s signature engineering accessible to a broader audience. It represents the brand’s commitment to quality and innovation during one of the most stylistically rich and mechanically significant periods in American automotive history.
