The Ross was a brass era steam automobile built in Newtonville, Massachusetts from 1906 to 1909.
[1] Company founder Louis S. Ross (1877–1927) gained national fame in the early 1900s while an employee of Stanley Motor Carriage Company racing his own-design and own-built [2] Stanley Steamer-powered "Wogglebug" race car at Ormond-Daytona Beach.
It is said the two engines independently powered a rear wheel and they had separate speed controls.
[1] Ross closed his steam car business in 1911 and focused on the manufacture of torpedo signals used by railroads.
[3] The company produced a 25 hp two-cylinder, shaft-driven model[4] that was the first steam-powered car to have the boiler, engine, and tanks all up front under the hood.
