Miller
A short-lived American brass-era automobile built by the Miller Car Company in Detroit from 1912 to 1913.

Overview
Miller was an American automobile marque associated with the Miller Car Company of Detroit, Michigan. The company was established at the Detroit Excelsior Works in 1911, during the brass era, when numerous small manufacturers entered the rapidly expanding motor-vehicle market with relatively simple touring cars, roadsters, and commercial vehicles. Production of Miller automobiles began in 1912 and continued only into 1913. The cars were offered in roadster and five-seat tourer forms. They used four-cylinder Wisconsin engines in two power ratings, producing approximately 30 horsepower or 40 horsepower. This gave the marque a product range typical of the period: a small selection of open passenger cars differentiated mainly by body style and engine output rather than by a broad model hierarchy. In 1912, the company also added a delivery wagon rated for a 1,000-pound payload, extending the Miller name into light commercial transport. The business was managed at the factory level by Guy Sintz. Available historical accounts do not identify a separate founder with certainty, and the surviving reference material does not establish a substantial dealer network, export operation, racing program, or long-term corporate strategy. The company was financially unsuccessful and ran out of money in 1913. The factory was then purchased by the Kosmath Company. The Miller automobile design and Guy Sintz moved to Pittsburgh, where the design was further developed into the Pennsy automobile. Miller therefore represents a brief Detroit automobile venture rather than the later beer brand that shares its name. Its historical importance lies in illustrating the crowded early American automotive market and the movement of designs, personnel, and manufacturing assets among small automobile companies. The marque disappeared after its short production run and has no evidence of continuing commercial operations.
History
The Miller automobile emerged from Detroit's early twentieth-century manufacturing environment, when the motor industry was populated by many small firms experimenting with vehicle designs, component suppliers, and production methods. The Miller Car Company was established at the Detroit Excelsior Works in 1911. The available historical record identifies Guy Sintz as the factory manager, but it does not clearly name the company's founder or document a large corporate organization behind the marque. Production began in 1912. Miller offered open-body passenger cars in roadster and five-seat touring configurations. The vehicles were powered by four-cylinder Wisconsin engines, available in versions rated at 30 horsepower and 40 horsepower. These specifications placed the cars within the mainstream of the brass-era market, in which manufacturers commonly relied on externally supplied engines and emphasized body style, power, and price as principal selling distinctions. In the same year, Miller broadened its range with a delivery wagon designed to carry 1,000 pounds, suggesting an attempt to serve both private motorists and small commercial operators. The company remained in business for only a short period. By 1913, Miller had run out of money and ceased to operate independently. The Kosmath Company purchased the factory, while the Miller automobile design and Guy Sintz were transferred to Pittsburgh. There, the design was refined and became the basis for the Pennsy automobile. This outcome reflects the instability of the early American automobile sector, where production assets and engineering concepts frequently changed hands as small manufacturers encountered financing, manufacturing, and distribution difficulties. The Miller marque did not develop into a durable automobile company. Its surviving significance is primarily historical: it documents a brief Detroit production venture, the use of Wisconsin engines by an independent manufacturer, and the transition of an early design into another marque after the original company failed. It should be distinguished from other businesses and brands named Miller, including the later American brewing company.
