Rolls-Royce 10 hp

The Rolls-Royce 10 hp was the first car produced as a result of the agreement of 23 December 1904 between Charles Rolls and Henry Royce, and badged as a Rolls-Royce. It was built by Royce's company, Royce Ltd., at its factory in Cooke Street, Hulme, Manchester, and sold exclusively by Rolls' motor dealership, C.S. Rolls and Co., at a price of 395 pounds. It was exhibited at the Paris Salon in December 1904 together with 15 hp and 20 hp cars and the engine for the 30 hp models. The 10 hp was a development of Henry Royce's first car, the Royce 10, of which he built three prototypes in 1903, itself based on a second-hand Decauville that Royce owned and believed he could improve; in particular he made his car significantly quieter than existing cars. Unlike the Royce 10 it had a radiator with a triangular top, which would appear on all later cars, and its water-cooled twin-cylinder engine of 1800 cc was enlarged to 1995 cc on later cars.
