1931 Buick Series 90

During the first three decades of the 20th century, Buicks popularly priced automobiles were equipped with overhead-valve engines. By the early 1930s, Buick engineers felt the long-lived six-cylinder engine had reached its limits in size and efficiency. In 1931, Buick introduced an all-new straight eight-cylinder engine used to power an entire line of models, with the top-of-the-line being the Series 90. Its eight-cylinder engine offered just over 100 horsepower and incorporated such innovations as an oil temperature regulator to cool the engine at high speeds and warm it in cold weather, as well as thermostatically controlled radiator shutters, as found on Packards and Duesenbergs. Many of the Fisher bodies fitted to the Series 90 Buick were shared with Cadillac.

The all-eight cylinder Buick lineup ranged from 221- to 345 cubic-inches and only a few parts were interchanged among the three engines. Buick offered four different series of cars which included the 50, 60, 80, and 90. The Series 90 was avail in eight different body styles and had a wheelbase of 132 inches. The convertible coupe was introduced part way through the year and had a leather interior in similar fashion to the other open bodystyles. The closed bodystyles had mohair interiors with silk roller shades for the rear side and rear window.

For 1931, roughly 25,503 examples of the Series 90 were built which accounted for about 18 percent of total Buick production.
