Overview
The Locomobile Company of America was an early American automobile manufacturer established in 1899. It began by commercializing a compact steam-powered vehicle developed by Francis and Freelan Stanley, helping bring motorcars to a broader middle-class market at a time when the automobile industry was still experimental. Its early cars were inexpensive runabouts, but their practical limitations—including lengthy steam-up times, limited water capacity, operational complexity, and fire risk—made the technology difficult to sustain as gasoline propulsion improved. Locomobile operated in Watertown, Massachusetts, during its first two years before moving production to Bridgeport, Connecticut, in 1900. The company produced more than 4,000 steam cars between 1899 and 1902 and offered several body styles by 1901. The Stanley brothers later left to establish the Stanley Motor Carriage Company, creating a direct competitor in the steam-car field. Locomobile subsequently experimented with internal-combustion automobiles and abandoned steam production entirely in 1903. Its gasoline cars occupied a very different market position. The company introduced larger, more powerful touring and sporting automobiles, including four-cylinder and six-cylinder models, and developed a reputation for careful construction, substantial engineering, and high prices. Locomobile competed in major early races, most notably the Vanderbilt Cup. In 1908, George Robertson drove a Locomobile to victory in the Vanderbilt Cup, making it the first American-built car to win an international automobile competition. The marque also had a military and commercial presence: a Locomobile was used during the Boer War as a generator and searchlight tractor, while the company produced Riker trucks from 1916 to 1921. The brand's defining luxury product was the Model 48, introduced in 1911 as the Type M. It used a large six-cylinder engine, a long wheelbase, extensive high-grade materials, and costly custom coachwork. The car could cost many times more than a mass-market Ford Model T, placing Locomobile among America's prestige automobile manufacturers. A smaller Model 38 was added in 1913, while the company gradually concentrated on six-cylinder automobiles. Durant Motors acquired Locomobile in July 1922 and retained it as a top-level marque. The Model 48 continued, but the brand later introduced less expensive and more contemporary cars such as the Junior Eight, Junior Six, Model 90, and 8-70. The 8-70's use of a readily available Lycoming engine was viewed negatively in the marketplace and weakened the marque's distinct identity. Further models, including the 8-86 and 8-88, arrived in 1929, but they could not reverse the company's decline. Automobile production ended in 1929, and Locomobile remains chiefly remembered for its pioneering steam cars, high-performance early racers, and imposing luxury Model 48.
History
Locomobile was formed in 1899 after John B. Walker acquired the plans and production rights for a Stanley steam vehicle. Walker soon sold half of his interest to Amzi L. Barber, but the partnership dissolved rapidly. Barber relocated the business to Bridgeport, Connecticut, while Walker pursued a separate automobile venture. The Stanley brothers served as general managers during the company's early period and later left to form the Stanley Motor Carriage Company. The first Locomobiles were small steam runabouts. They were relatively affordable and attracted customers who wanted the novelty and mobility of a motorcar, including salesmen and physicians. More than 4,000 were built from 1899 through 1902. However, the cars required substantial preparation, had limited operating range between water refills, and could be difficult and hazardous to operate. Locomobile offered several body styles by 1901, but the shortcomings of steam propulsion became increasingly important as gasoline technology matured. The company began developing gasoline automobiles in 1902, including a four-cylinder design associated with engineer Andrew L. Riker. In 1903, it stopped building steam cars and returned the relevant rights to the Stanley brothers. Gasoline Locomobiles were larger, faster, and much more expensive than their predecessors. The 1904 touring car used a front-mounted four-cylinder engine and a substantial steel-framed chassis. Sporting and racing successes helped establish Locomobile as a manufacturer of high-quality luxury vehicles rather than merely an early steam-car novelty. Racing was an important part of the brand's early identity. Locomobile competed in the Gordon Bennett Cup and Vanderbilt Cup, although mechanical failures affected some entries. George Robertson's 1908 Vanderbilt Cup victory was the company's greatest racing achievement and a landmark for American automobile engineering. Locomobile also participated in long-distance events, including the Los Angeles–Phoenix rally, and produced vehicles with military utility. During the Boer War, one vehicle served as a generator and searchlight tractor, and Locomobile later manufactured Riker-branded trucks, 1,150 of which were used in Europe during the First World War. The Type M, generally known as the Model 48, became the marque's signature automobile after its 1911 introduction. Its very long chassis, large side-valve six-cylinder engine, careful workmanship, and expensive custom finishes placed it at the top of the American luxury market. Tiffany Studios supplied customized lamps and metalwork for some cars. The Model 38, a smaller six-cylinder automobile, joined the range in 1913, and Locomobile discontinued its four-cylinder offerings by 1914. Durant Motors acquired the company in July 1922. Durant retained the Model 48 and used Locomobile as a premium brand, but the marque had to respond to changing consumer expectations and the economic pressure affecting luxury manufacturers. The Junior Eight appeared in 1925 at a lower price, the short-lived Junior Six followed in 1926, and the Model 90 and 8-70 expanded the range. The 8-70's use of an off-the-shelf Lycoming engine was seen as inconsistent with Locomobile's established engineering character. New 8-86 and 8-88 models were introduced for 1929, but the business did not survive. Production ended that year.

Products and positioning
Initially an accessible pioneer of steam motoring, later a prestige American manufacturer of finely built luxury and sporting automobiles.
Steam automobiles · 1899
Steam runabouts
Locomobile's first products were compact, wood-framed steam runabouts using twin-cylinder engines and naphtha-fired boilers. They were sold at comparatively accessible prices and helped introduce motorcars to middle-class buyers. Their drawbacks included limited water capacity, lengthy steam preparation, difficult operation, and fire risk. More than 4,000 examples were produced between 1899 and 1902.
Luxury automobile
Locomobile Type 40
The Type 40 represented Locomobile's move toward powerful gasoline luxury cars. Later examples used large engines and substantial chassis construction, emphasizing speed, prestige, and workmanship rather than the low price of the earlier steam runabouts. The model family was associated with the company's sporting and competition image.
Luxury automobile · 1911
Locomobile Model 48
Introduced in 1911 as the Type M, the Model 48 was Locomobile's defining flagship. It featured a very long wheelbase, a large six-cylinder engine, conservative mechanical architecture, and exceptionally costly materials and workmanship. Custom lamps and metal details could be supplied by Tiffany Studios. The model remained in production through the Durant years until Locomobile closed in 1929.
Luxury automobile · 1913
Locomobile Model 38
Added in 1913, the Model 38 was a somewhat smaller six-cylinder automobile closely related in concept to the Model 48. It allowed Locomobile to offer a second luxury model while maintaining its concentration on large six-cylinder cars.
Commercial vehicle · 1916
Riker trucks
Locomobile produced trucks under the Riker name from 1916 to 1921. The vehicles had practical military and logistical value, and 1,150 Riker trucks were used in Europe during the First World War.
Passenger automobile · 1925
Junior Eight 8-66
Introduced in 1925, the Junior Eight was a smaller and less expensive straight-eight intended to broaden Locomobile's customer base beyond the very costly Model 48. It was phased out in 1928.
Passenger automobile · 1926
Junior Six
The Junior Six was introduced as an even smaller Locomobile model during the Durant period. It remained in the range for only one model year.
Luxury automobile · 1926
Model 90
The Model 90 appeared in 1926 as a larger Locomobile offering and continued until the end of production. It belonged to the company's attempt to refresh its range during the Durant era.
Passenger automobile · 1927
8-70
Introduced in 1927, the 8-70 used a Lycoming straight-eight engine. Although it added a modern eight-cylinder model to the line, its use of an off-the-shelf engine was perceived as weakening Locomobile's distinctive engineering identity.
Passenger automobile · 1929
8-86 and 8-88
The 8-86 and 8-88 were introduced for 1929, the company's final model year. They arrived too late to overcome Locomobile's commercial decline, and production ended before the marque could recover.
