Riley 17hp / 17-30hp. (1914-23)
The 17hp was a surprise launch at the 1913 Olympia show, with no warning given of it's arrival. The car was designed by Harry Rush, and was launched as the new flagship model. It survived until the outbreak of war, even though only 6 are thought to have been sold.
After the war, it was the only Riley put into immediate production, using up stocks of parts from 1914, and sold well until the introduction of horse-power tax in 1921. This led to widespread sales resistance, and the (renamed) 17-30 was slowly phased out by 1923. The final cars had the new upright 'V' Radiator, as opposed to the original round unit.
