1932 Maclaughlin-Buick Series 90 Convertible Coupe
In the early 1930s, with engineers feeling that the long-lived six-cylinder engine had reached its limit in size, Buick introduced an all-new straight eight-cylinder engine for its cars. For 1931, Buicks line of cars were all powered by eight-cylinder engines, with the top of the line offering being the Series 90. It came equipped with a 104 horsepower engine that featured an oil temperature regulator to cool the engine at high speeds. It also helped warm the engine in cold weather.
