The Riley Sprite is a two-seater open sports car model produced by Riley Motors from 1935 to 1938. It followed on from the company's Imp and MPH sports cars.[1] The Sprite was mostly built with 4 cylinder engines, although alternatively a 6 cylinder engine was available.[2] The chassis was based on that of the preceding 'MPH' model.[1] Its racing success (especially in the form of the Riley T.T. Sprite model)[3] led to the adoption of 'Sprite' as a designation for the top-end sportier model in the Riley Kestrel saloon car range of the time.[4] [5]
