The Stutz Vertical Eight (also known as the Stutz Model 8, or Stutz 8-Cylinder) was a series of luxury automobiles produced by the Stutz Motor Car Company of Indianapolis, Indiana, from 1926 until the mid 1930s. Introduced as the company's first inline eight powered model, the Vertical Eight represented a major technological leap for Stutz, featuring an advanced single overhead camshaft (SOHC) engine and the pioneering "Safety Stutz" chassis. It earned a reputation as one of the fastest American production cars of the late 1920s, with certain Black Hawk Speedster variants capable of exceeding 100 mph (161 km/h).[1]
The car was offered in a wide variety of body styles, ranging from formal sedans and broughams to sporty speedsters and roadsters, many of which were coachbuilt by firms such as Brewster, LeBaron, Rollston, Waterhouse, Weymann and others. Production overlapped several series designations (AA, BB, M, MA, MB) with incremental updates before the Great Depression forced changes to the lineup.[2][3]
