Stevens-Duryea was an American manufacturer of Veteran and Brass Era automobiles in Chicopee Falls, Massachusetts, between 1901 and 1915 and Vintage Cars from 1919 to 1927.

The rights and engineering for the Stevens-Duryea were acquired by a new company in 1919 and resumed car production on a limited scale until 1927.

Stevens Arms had recently purchased the factory of Victor Steam and bicycle maker Overman, and Stevens-Duryea shared the premises for several months.

By 1904 the stanhope runabout, was called the Model L. It had a flat-mounted water-cooled 7-hp engine, situated amidships of the car, four speed gearbox (three forward, one reverse), wire wheels, full-elliptic springs, and tiller steering.

[8][9] For 1906 the new Model S Big Six was introduced with a huge 9.6 liter six-cylinder motor, seven-seat tulipwood and aluminum body, weighing 2,900-lbs (1315-kg) and priced at $5,000, equivalent to $169,556 in 2023.

[10] Introduced at the January 1906 New York Motor Show, it along with Franklin, was one of two six-cylinder American cars shown.

[14][15] In 1909 Frank Duryea at the age of 40, on doctor's advice, retired from daily work with Stevens-Duryea due to 20 years over-work and job related stress.

The C-Six engine was rated at 44.6-hp and was priced at $4,500 as a touring car, ranging up to $5,950 (equivalent to $183,428 in 2023) as a 7 passenger Berline.

[17] J. Frank Duryea was now the majority shareholder and turned down financial investments that were conditional on adding a lower priced line of cars.

He did not feel Chicopee was a good location for volume production and was not interested in lowering his manufacturing standards.

[17] One building portion of the plant was retained to supply and make parts for the estimated 14,000 Stevens-Duryeas built.

[17] In July 1919, Ray S. Deering, engineer Thomas L. Cowles and former employees purchased the small factory building, name and goodwill of Stevens-Duryea from Frank Duryea for $100,000.

[1] Extensive advertising, hiring of well-known engineers, building a new plant and announcement of plans did not result in many cars being produced.
